In this article I will share some reflections on my own experience as a historian. However, I will refrain from proposing my own case as a model. I dislike preaching; moreover, I regard ego-centred preaching as a ridiculous posture. So please: note what I will say, and then follow a completely different path.

Full textAbstract:
The rubric of the presence of Buddhist sculpture in the absence of an actual deity represents an admirable aspect of Buddhist art, especially sculpture, where the best works have drawn on this paradox in an astounding fashion. An important element in the realization of this religious archetype is the Buddhist statues’ sublime poses. This article demonstrates the Buddhist posture hierarchy, based on a case study of a Tang-Dynasty Chinese Buddhist Bronze collected by the Pulitzer Arts Foundation, the posture of which is identified as lalitāsana: one leg pendant and the other bent horizontally. This article shows how this pose engendered various other compositional situations and postures popular in East Asia icon design and, moreover, that this sculpture might form part of an assemblage, where the pose indicates the central Buddha figure, to which all of the other figures are formally and doctrinally posed following a hierarchy. This article argues that Buddhist figures of different religious ranks are characterized by their pose and degree of movement. This research proves that the myriad forms of Buddhist postures and hierarchy have been devised to illustrate mythologies and philosophical, doctrinal, or social concepts, and their representations, in turn, have engendered other myths and beliefs.

Rice harvesting is a high ergonomic risk due to the working position, an awkward posture, and the repetition activity. Rice harvesting causes body pain in the part of low back, hand, and wrist. This study aims to (1) identify the characteristics of non-mechanical rice harvesting; (2) determine the working posture of rice harvesters using the Ovako Working Assessment System (OWAS) method, Quick Exposure Checklist (QEC), Rapid Entire Body Assessment (REBA), Postural Ergonomics Risk Assessment (PERA); and (3) determine the best method to assess harvesters work posture. An observation was conducted to nine of healthy workers in Bantul and Sleman districts, Daerah Istimewa Yogyakarta (DIY) province. The questionnaire was set to collect respondent demographics data. Data for harvester body posture (neck, trunk, leg, wrist, lifting load, shoulder) repetition, duration and force were collected by observation in the field. A sickle was used to cut rice straw, while a manual gepyok and mobile hand thresher was used to threshing rice panicles. Four methods were applied to assess the work posture, i.e., OWAS, QEC, REBA, PERA methods. Based on observation, five workstations were identified: (1) cutting rice straw, (2) transporting rice straw, (3) threshing of panicles, (4) sorting, and (5) packaging and transporting. REBA and PERA showed a similar trend of the ergonomic risk, high to low risk took place in workstation transporting rice straw, packaging and transporting, cutting, and threshing. The assessment of work posture that is most suitable for non-mechanical harvesting methods was the REBA method with an accuracy of 92.9%.

Full textAbstract:
In the last two decades, incorrect posture has become significantly more widespread, particularly among school-aged children. According to various studies, scoliosis is one of the most prevalent incorrect postural types seen in school-aged children. The purpose of our study is to find out how common "Scoliosis" is among Albanian children. Methodology: About 308 kids aged 10 to 13 years (n = 151 girls, n = 157 boys) were randomly selected from Tirana public schools for this study. This group took part in a Posture Shape Examination (Anterior View), using Grid Chart Postural Analysis and the platform “Posture Screen Mobile®-PSM” (iPod). To provide exact information on their looks, children were photographed from the front (upright standing posture) wearing as little as possible. We analyzed the data statistically using "IBM SPSS Statistics 20," which included Descriptive and Frequency Analyze. Results: Our findings revealed that 34 individuals, or 11.03 % of the youngsters, had Scoliosis. This improper posture was more prevalent in 13-year-old youngsters (19.5%) than in children aged 10, 11, or 12. In comparison to females, boys were more impacted by scoliosis (12.7%) than girls (9.3%). The results reveal a minor difference in the degrees of postural displacement between boys (5.81850) and females (5.43610). Furthermore, postural displacement is greater in 13-year-old males (7.76500) and 12-year-old girls (6.14580). Conclusions and Recommendations: Based on the results of our study we conclude that incidents of anterior postural asymmetry occurred even in Albanian school-age children. Scoliosis, even why is detected more in boys, seems to be present in both genders. Based on these conclusions we recommend that parents, teachers, and children should be more informed about good posture and the problems that might arise from an incorrect posture. Further studies are important to be conducted in this field, in order to prevent the occurrence of these deviations and their aggravation in our young generation.

Full textAbstract:
Upright stance in humans requires an intricate exchange between the neural mechanisms that control balance and those that control posture; however, the distinction between these control systems is hard to discern in healthy subjects. By studying balance and postural control of a participant with camptocormia — an involuntary flexion of the trunk during standing that resolves when supine — a divergence between balance and postural control was revealed. A kinematic and kinetic investigation of standing and walking showed a stereotyped flexion of the upper body by almost 80° over a few minutes, and yet the participant’s ability to control center of mass within the base of support and to compensate for external perturbations remained intact. This unique case also revealed the involvement of automatic, tonic control of the paraspinal muscles during standing and the effects of attention. Although strength was reduced and MRI showed a reduction in muscle mass, there was sufficient strength to maintain an upright posture under voluntary control and when using geste antagoniste maneuvers or “sensory tricks” from visual, auditory, and haptic biofeedback. Dual tasks that either increased or decreased the attention given to postural alignment would decrease or increase the postural flexion, respectively. The custom-made “twister” device that measured axial resistance to slow passive rotation revealed abnormalities in axial muscle tone distribution during standing. The results suggest that the disorder in this case was due to a disruption in the automatic, tonic drive to the postural muscles and that myogenic changes were secondary. NEW & NOTEWORTHY By studying an idiopathic camptocormia case with a detailed biomechanical and sensorimotor approach, we have demonstrated unique insights into the neural control of human bipedalism 1) balance and postural control cannot be considered the same neural process, as there is a stereotyped abnormal flexed posture, without balance deficits, associated with camptocormia, and 2) posture during standing is controlled by automatic axial tone but “sensory tricks” involving sensory biofeedback to direct voluntary attention to postural alignment can override, when required.

Considerando que o treinamento suspenso (TRX® ST) remete à ideia de um treinamento completo, trabalhando o corpo como uma unidade, acredita-se que sua prática pode trazer grandes benefícios. Nessa perspectiva, objetivou-se identificar o efeito do treinamento suspenso TRX® ST sobre a funcionalidade, a postura estática da coluna vertebral e as dores corporais em geral em uma mulher idosa, a qual foi submetida à avaliação (1) da funcionalidade por meio do protocolo proposto pelo Senior Fitness Test (SFT); (2) das dores corporais utilizando-se o instrumento Informações sobre Dor nas Costas (IDC); e (3) da postura estática da coluna vertebral utilizando o Flexicurva antes do início do treinamento (1ª avaliação) e após a última sessão do treinamento (2ª avaliação). O treinamento suspenso (TRX® ST), composto de exercícios para força e flexibilidade, foi realizado durante 12 semanas, sendo cada semana composta de duas sessões, com duração de até 50 minutos cada. A participante apresentou: (1) melhora da funcionalidade (aumentando de 12 para 19 o número de repetições de sentar e levantar; diminuindo de 5,9s para 4,5s o tempo de sentar e caminhar; e diminuindo de 6cm para 0cm o resultado de sentar e alcançar, no STF), exceto nos membros superiores; (2) diminuição da dor nas regiões dorsal (de EVA intensidade 1 para intensidade 0), lombar (de EVA intensidade 1 para intensidade 0) e de glúteos (de EVA intensidade 2 para intensidade 1); e (3) mudança da postura da coluna lombar, passando de uma retificação (24°) para uma lordose fisiológica (41°). Em contrapartida, os resultados também demonstraram que a postura da coluna torácica não foi alterada pelo treinamento. Tendo em vista que esses são resultados iniciais, se faz necessária a condução de novos estudos a fim de verificar os efeitos do treinamento com TRX® ST sobre as variáveis dor, postura estática e funcionalidade, bem como sobre a postura dinâmica e a qualidade de vida de seus praticantes.Palavras-chave: Educação Física e Treinamento. Idoso. Postura. Dor.AbstractConsidering that suspended training (TRX® ST) refers to the idea of a full training, it is believed that its practice can bring great benefits. Thus, it was [ aimed to verify the effect of suspended training TRX® ST on the functionality, the static posture of the spine and general body pain in an elderly woman. The following were evaluated :(1) funcionality using Senior Fitness Test (SFT) protocol; (2) body pain using a validated questionnaire; and (3) spine static posture using Flexicurve before the training (1st evaluation) and after the last training session (2nd evaluation). The suspended training TRX® ST, that consists of exercises for strength and flexibility, was performed for twelve weeks, in such ways that each week consisted of two sessions, lasting 50 minutes each. The participant presented: (1) an improvement of the functionality (increasing from 12 to 19 repetitions the number of repetitions of sitting and standing up; decreasing from 5.9s to 4.5s the number of sitting and walking ; and decreasing from 6cm to 0cm the result of sitting and reaching up, in STF), except in upper limbs; (2) a reduction of pain in the dorsal, lumbar and gluteal regions; and (3) postural modifications in the lumbar spine, passing from a correction (24°) to a physiological lordosis. (41°). In contrast, the results also showed that the posture of the thoracic spine was not affected by the suspended training in twelve weeks. Since these are initial results, it is necessary to conduct further studies in order to verify the effects of training with TRX® ST on the variables pain, static posture and functionality, as well as on the dynamic posture and the quality of life of its practitioners.Keywords: Physical Education and Training.

Full textAbstract:
Purpose The purpose of this paper is to investigate the medical incident responses from two public hospitals in Hong Kong, namely, Kowloon Hospital and Caritas Medical Centre, in order to improve the strategic preparation for crisis management in hospitals. Design/methodology/approach The paper analyses two medical incidents using Situational Crisis Communication Theory by Coombs (2007). The two case studies presented herein demonstrate the importance of consistency in terms of crisis responses. Findings For the first case, the crisis responses from different parties after the incident, including Hospital Authority, the doctor and the nurses from Kowloon Hospital, are contradicting to each other. First, Hospital Authority confirmed that the incident is solely an accident which is a denial response. Second, the doctor passed the responsibility to the nurses which is a scapegoating response. Third, the nurses tend to reduce the responsibility for the death of patient by excusing strategy. As a whole, their responses are inconsistent to each other. For the second case, Caritas had initially denied the responsibilities, but finally had given partial apology under public pressure. That makes people think that Caritas does not really regret. Originality/value Rebuilding posture should be used instead of denial and diminishment posture. However, public organization and civil servants are reluctant to use a full apology due to possible legal consequences. The apology ordinance would ease the pressure to express regret and sympathy.

Full textAbstract:
The assessment of posture and asymmetries is common in musculoskeletal clinical practice, and correction is a frequent goal. In this setting, posture and asymmetries are usually interpreted in terms of musculoskeletal issues. This study aimed to evaluate spinal asymmetries in case studies of unilateral nephroptosis. A systematic review was performed using PubMed, CINAHL, Scopus and Web of Science. We included case reports and case series of nephroptotic patients which showed diagnostic imaging that allowed us to assess the presence of spinal asymmetries in the frontal plane. The methodological quality of the selected studies was assessed by using the CAse REport (CARE) checklist. Nineteen studies were included, with a total number of 78 reported patients (69 women) ranging 22 to 44 years old (mean: 29). Only one patient presented with medial nephroptosis, while the rest presented with caudal migration. Ninety-one percent of the cases affected the right kidney. All cases but two showed homolateral flank closure (lower rib descent, iliac crest raise and/or homolateral side-bending). The correction of nephroptosis, either by supine position or surgical treatment, removed asymmetries in some cases while other cases improved only partly. Manual therapists must consider visceral implications while assessing body posture. Further, since the most common symptom of nephroptosis is loin pain, and it has been claimed that loin pain is underdiagnosed, manual therapists should consider its potential presence during clinical practice. Finally, being that nephroptosis shares several features with idiopathic lumbar scoliosis (type of patient, postural adaptation), more research is needed regarding any possible relation between them.

Full textAbstract:
Costello syndrome (CS), a rare syndrome with multisystemic involvement inherited as a dominant trait, is characterized by developmental delay, coarse facial appearance, cardiac defects including hypertrophic cardiomyopathy, skin abnormalities, brain complications, and a predisposition to certain malignancies. The musculoskeletal system is particularly affected in CS, with peculiar orthopedic anomalies that impact posture and gait. Dystonia has been recently documented to contribute to abnormal postures and musculoskeletal anomalies characterizing CS, suggesting the possible use of pharmacological treatments to treat these complications. We report the case of a child affected by CS displaying a particularly severe musculoskeletal involvement with dystonic posture especially in the arms and legs. The Movement Disorder-Childhood Rating Scale (MD-CRS) and a gait analysis were used to assess clinical patterns of hyperkinetic movement disorder and dystonia. The child was further treated with trihexyphenidyl for six months with a final dosage of 14 mg. MD-CRS and gait analysis assessments provided evidence for a significant improvement of posture and the related musculoskeletal problems with no side effects. Our preliminary study report provides first evidence that pharmacological anti-dystonia treatment significantly improves movement and posture disorders in patients with CS. Further studies enrolling larger cohorts of patients should be performed to validate these preliminary observations.

The aim of this study was to know issue of the relationship between mandibular asymmetry and body posture. The literatures of mandibular asymmetry and body posture published in the last 10 years (2012-2022) which were collected from the electronic databases PubMed and Google Scholar. The data obtained was anaylized using observational, prospective, retrospective, case reports, systematic reviews and meta-analyses, showed that there is a relationship between themandibular and C2-3 with the rela-tion of the suprahyoid, hyoid bone, infrahyoid and sternocleidomastoid muscles connecting to spine. So, the changes in mandi-bular position will also change the body posture, and body posture will also affect the position of the mandibular with spinal de-formities which results in distortion of the vertebral column and asymmetrical face, shoulders, and waist. It was concluded that all studies cited in this literature review reported thatmandibular asymmetry and body posture have a reciprocal relationship.

ABSTRACT
Cerebral palsy is a motor problem as a result of non-progressive brain lesions in impaired brain development. In children who suffer from Cerebral Palsy experience damage to the brain that is permanent. The characteristic of Cerebral Palsy with the Spastic Hemiplegic type is characterized by the appearance of problems in the upper and lower limbs of one side of the body. The intervention given in this case is a postural control exercise which aims to improve the child's ability to control body position with the aim of stability and orientation. This research method is experimental, the research design uses case studies and data collection techniques use Pre and Post Tests. The sampling technique used was accidental sampling. Examination of posture using a posture assessment scale and functional examination of activities using the GMFM form. After six sessions of therapy, the results showed an improvement in posture and an increase in the functional score of children's activities, although not significant. Postural control exercise programmed to patients is able to improve posture and increase the functional ability of children's activities.

No studies have described physical therapy treatment for children with congenital Zika virus syndrome. In this case report, the authors aimed to improve postural control, mobility, and social skills in a 17- to 18-month-old child with congenital Zika virus syndrome through a period of 6-week home-based, intensive physical therapy intervention. Outcome measures were the Posture and Postural Ability Scale, Pediatric Evaluation of Disability Inventory, and Caregiver Priorities and Child Health Index of Life With Disabilities. From pre- to postintervention, the child’s Posture and Postural Ability Scale scores increased for level of postural ability in the prone position and postural alignment in all 4 positions (prone, supine, sitting, and standing). The authors saw an overall improvement in mobility and social skills from preintervention to follow-up 3 weeks after intervention. In conclusion, postural control, mobility, and social skills improved for a child with congenital Zika virus syndrome after physical therapy intervention, but future studies are required to confirm these findings.

Full textAbstract:
Common practices to improve the ability to swallow include modifying physical properties of foods and changing the posture of patients. Here, we quantified the effects of the viscosity of a liquid bolus and patient posture on the bolus pathway and pharyngeal residue using a computational fluid dynamics simulation. We developed a computational model of an impaired pharyngeal motion with a low pharyngeal pressure and no pharyngeal adaptation. We varied viscosities from 0.002 to 1 Pa·s and postures from −15° to 30° (from nearly vertical to forward leaning). In the absence of pharyngeal adaptation, a honey-like liquid bolus caused pharyngeal residue, particularly in the case of forward-leaning postures. Although the bolus speed was different among viscosities, the final pathway was only slightly different. The shape, location, and tilting of the epiglottis effectively invited a bolus to two lateral pathways, suggesting a high robustness of the swallowing process. NEW & NOTEWORTHY Thickening agents are often used for patients with dysphagia. An increase in bolus viscosity not only reduces the risk of aspiration but also can cause a residual volume in the pharynx. Because information obtained from videofluoroscopic swallowing studies is only two-dimensional, measurement of pharyngeal residue is experimentally difficult. We successfully quantified the three-dimensional bolus pathway and the pharyngeal residual volume using computational modeling and simulation.

Purpose – The purpose of this paper is to demonstrate three techniques to extract human factor information from specific railway maintenance tasks. It describes the techniques and shows how these tools can be applied to identify improvements in maintenance practices and workflow. Design/methodology/approach – Three case studies were conducted on single group of technicians (n=19) at a railway maintenance workshop in Luleå, Sweden. Case study I examined the posture of the technicians while they were changing the brake shoes of freight wagons; the study employed the Standard Nordic Questionnaire and a videotape using the Ovako Working Posture Analysis System (OWAS). Case study II looked at maintenance repair times required to change the wheel axle on freight wagons at the workshop. A video filming method suggested by the European Agency for Safety and Health at Work was used to measure actual maintenance time. Finally, case study III considered the technicians’ (n=19) perception of work demands, their control over the work and their social support while performing maintenance tasks (brake shoe and wheel axle maintenance); to this end, the case study used a demand control support questionnaire. Findings – In the first case study, the Standard Nordic Questionnaire confirmed that technicians at this particular railway vehicle maintenance workshop suffer from back and shoulder pain. The Ovako Working Posture Analysis showed that 21 percent of the working time required to fit the brake wedge and cotter pin fits into two OWAS categories: category 3, where “change is required as soon as possible,” and category 4, where “change is required immediately”. Problems stem from poor workplace layout, incorrect posture and inaccessibility of tools and components. In the second study, the video analysis indicated that the working time to change the wheel axle of a freight wagon is greatly affected by poor workplace layout. The third case study showed that the technicians have lower “psychological demands” (mean=13), “higher control over work” (mean=16) and “high social support” (mean=22). Practical implications – The objective of this study was to apply knowledge about human factors to the functional relationships between maintenance personnel, tasks and the working environment to improve safety. If the workplace layout, working posture, maintenance manuals and accessibility of tools are poorly planned, maintenance performance can be adversely affected. The results of this study should assist maintenance management to design new policies and guidelines for improving the work environment. Originality/value – Three case studies were conducted at a railway maintenance workshop in Luleå, Sweden, to collect data on how human factors affect various railway maintenance tasks.

The food industry is one of the most important industries in human life. Raimin SME is a form of business engaged in the food sector that produces tofu. The tofu production process at Raimin SMEs is mostly done manually. There are some subjective complaints from workers when they are active on the production floor. This complaint was obtained by conducting an initial survey in the form of filling out the Nordic Body Map. Unnatural posture is one of the problems faced by workers, especially in the process of cutting tofu and in terms of ergonomics, working posture in the process of removing tofu from mold and process of tofu cutting. The purpose of this research is to design a tool based on an ergonomic approach so as to reduce the risk of injury and excessive fatigue. The tool in question is also expected to increase the efficiency of processing time. Based on the results of the Nordic Body Map, the most problematic body parts are known, then the Rapid Entire Body Assessment (REBA) and Workplace Ergonomic Risk Factor (WERA) scores are calculated. The results of the REBA calculation for removing tofu from mold resulted in a score of 11 (very high risk category). The results of calculations using the WERA method in the tofu cutting process resulted in a score of 37 (medium risk category). The results of the heart rate (HR) measurement show that workers need energy of 6.34 kcal/minute (classified in heavy work). Furthermore, tool design, simulation with CATIA software and implementation on the production floor are carried out. Of the 8 design concepts, the best design was selected and a simulation was carried out with CATIA software, the result of the REBA score of the cutting process was reduced to 3 (low risk category). The results of the implementation of the tool show that the REBA score after implementation decreases to 3, the WERA score becomes 27, and the energy consumption rate decreases to 3.98 kcal / min, which is categorized as light work. The standard time for removing tofu from mold decreased by 48% (from 48.05 sec to 24.9 sec), while for tofu cutting process it decreased by 69.2% (from 44.58 sec to 13.70 sec).

Full textAbstract:
Using survey data collected in 1995, this article examines how Mexicans assess responsibility for the 1995 Peso Devaluation Crisis. Mexicans primarily blame former president, Carlos Salinas, but a significant number also blame external actors and institutions for the crisis. The tendency to blame recent presidents is related to assessments of economic conditions and to partisanship; by contrast, the tendency to blame external actors and institutions is related to traditional Mexican nationalism with its defensive posture toward the United States. This posture is found primarily among the economically maginalized and the politically alienated. Nationalism remains an important force in citizen politics in Mexico, but its meaning is still contested. A travéés de una encuesta de 1995, este articulo examina la manera en que los mexicanos deslindan la responsabilidad de la crisis de la devaluacióón del peso en 1995. Por lo general, los mexicanos culpan al presidente Carlos Salinas, aunque un buen numero atribuye la crisis a factores e instituciones externas. La tendencia a culpar a los presidentes recientes se relaciona con la evaluacióón de las condiciones econóómicas y las lealtades de partido; por contraste, la tendencia a culpar a factores e instituciones externas se relaciona con el nacionalismo tradicional y con su actitud defensiva hacia los Estados Unidos. Dicha actitud se percibe principalmente entre los marginados econóómicamente y los alienados polííticamente. De tal modo que el nacionalismo aúún permanece como una fuerza importante en la políítica del ciudadano en Mééxico aunque su significacióón todavíía se disputa.

Radiographic osteoarthritis of the knee is very common in Saudi patients, especially in the patellofemoral compartment.
Some studies have considered repetitive daily prayer activities as a factor of causation. However prevention and management recommendations appear to be non-existent in the literature. This report describes the case of chronic bilateral anterior knee pain in a devout adult male, which was dramatically alleviated by simply using a padded cushion under the prayer rug. Simple strategies of temporarily modifying prayer posture, insuring good prayer form, and adequate knee padding, may offer promise as low tech and economical solution for the management of anterior knee pain in this cultural group.

Purpose: To describe multidisciplinary interventions aimed at treating a child diagnosed with an autism spectrum disorder. Case description: The mother sought medical help for her son who exhibited language delays. He was agitated, did not respond to calls, and exhibited a delay in speech development. For psychopharmacological treatment, risperidone 1 mg/mL associated with vitamin D, was prescribed. Multidisciplinary therapies were proposed and applied according to the patient’s needs. In sessions with a speech therapist, he responded to all stimuli, demonstrating good interest in the proposed activities and maintained good eye contact. He performed several circuits to improve posture, image, laterality, and body scheme. After participating in hippotherapy supervised by several professionals, the child exhibited an improvement in social interaction, motor performance, especially in posture practice, and in communication. After interposing equine-assisted therapy with intellectual clinic sessions, he started activities at an inclusive school. Discussion: Multidisciplinary interventions demonstrated effectiveness and continuous and positive evolution in the patient. Studies reporting multidisciplinary therapies are relevant for demonstrating the importance of this method and the adaptation to the reality of each autistic patient.

Full textAbstract:
Musculoskeletal diseases represent a constant phenomenon in occupational health and safety (OHS) despite the large effort at governmental and technical levels. In the industrial context, numerous studies have dealt with the evaluation of the physical demand of workers. Moreover, numerous studies have investigated the problem, providing tools for ergonomics analysis. However, practical approaches aimed at integrating ergonomics issues in risk assessment activities are still scarce. To reduce such a gap, the current study proposes a procedure for the evaluation of the static working postures of workers to be included in the risk assessment activities. Such an approach is based on the ISO 11226 standard, providing a practical checklist that can be used both at the workstation’s design stage and during risk assessment activities. Its effectiveness was verified through a case study at a manufacturing company. The results achieved showed that as well as the non-conformity of the workstations’ design, the lack of training of the operators on how to maintain a neutral posture while working can also lead to awkward postures of the trunk and head. Additionally, the proposed methodology allowed us to verify the correctness of each workstation based on the physical characteristics of the workers, providing a useful guideline for the company managers on how to properly assign working tasks.

To carry out an integrative literature review on the postural analysis softwares available today. It is an integrative-narrative review of qualitative and methodological nature performed during April-July 2014. As inclusion criteria, the articles should be bibliographical or original research and available with full access. At first, we proceeded to the identification of the keywords for the softwares related to postural assessment commonly used in the health field, in such case "posture", "software", and "postural assessment". The search was narrowed by publication date from 2002 to 2014. Through the information acquired from the articles and from the software developers, information on 12 programs that assist the postural evaluation were obtained - Alcimage, All Body Scan 3D, Aplob, APPID, Biotonix, Corporis Pro, Fisimetrix, Fisiometer Posturograma, Physical Fisio, Physio Easy, Posture Print and SAPO. However, only one tool has more information and studies, namely SAPO. There are many postural analysis softwares available on the internet today, however, these are quite disparate in relation to possible answers and are still poorly widespread as research tools.

Full textAbstract:
In this article, Austin Walker discusses streaming, the practice of broadcasting the gameplay footage. Providing a brief analysis of the range of streaming practices, Walker argues that streaming represents a sea change in how players share and collaborate, adding new sorts of social interactivity to an experience that was, for so long, solitary. Live streaming’s novelty grants it special status as a practice still in formation, making it especially useful in analyzing how late capitalism identifies and appropriates fresh cultural activity--doing so in this case through the development of an infrastructure that supports and encourages voluntary self-surveillance. While there are resistive elements of live-streaming, such as allowing new voices access to broadcast capabilities, streaming also represents socialized labour. Walker separates streaming into two stances: the active streaming posture, where streamers voluntarily choose to broadcast their play, and the passive streaming posture, where streaming is automatically incorporated into the hardware and/or software of the gaming platform and players are unable to opt in or out.

Full textAbstract:
Inspired by the notion of swarm robotics, sensing, and minimalism, in this paper, we study and analyze how a collection of only 1D depth scans can be used as a part of the minimum feature for human body detection and its segmentation in a point cloud. In relation to the traditional approaches which require a complete point cloud model representation for skeleton model reconstruction, our proposed approach offers a lower computation and power consumption, especially in sensor and robotic networks. Our main objective is to investigate if the reduced number of training data through a collection of 1D scans of a subject is related to the rate of recognition and if it can be used to accurately detect the human body and its posture. The method takes advantage of the frequency components of the depth images (here, we refer to it as a 1D scan). To coordinate a collection of these 1D scans obtained through a sensor network, we also proposed a sensor scheduling framework. The framework is evaluated using two stationary depth sensors and a mobile depth sensor. The performance of our method was analyzed through movements and posture details of a subject having two relative orientations with respect to the sensors with two classes of postures, namely, walking and standing. The novelty of the paper can be summarized in 3 main points. Firstly, unlike deep learning methods, our approach would require a smaller dataset for training. Secondly, our case studies show that the method uses very limited training dataset and still can detect the unseen situation and reasonably estimate the orientation and detail of the posture. Finally, we propose an online scheduler to improve the energy efficiency of the network sensor and minimize the number of sensors required for surveillance monitoring by employing a mobile sensor to recover the occluded views of the stationary sensors. We showed that with the training data captured on 1 m from the camera, the algorithm can detect the detailed posture of the subject from 1, 2, 3, and 4 meters away from the sensor during the walking and standing with average accuracy of 93% and for different orientation with respect to the sensor by 71% accuracy.

Full textAbstract:
Inertial measurement units have recently shown great potential for the accurate measurement of joint angle movements in replacement of motion capture systems. In the race towards long duration tracking, inertial measurement units increasingly aim to ensure portability and long battery life, allowing improved ecological studies. Their main advantage over laboratory grade equipment is their usability in a wider range of environment for greater ecological value. For accurate and useful measurements, these types of sensors require a robust orientation estimation that remains accurate over long periods of time. To this end, we developed the Allumo software for the preprocessing and calibration of the orientation estimate of triaxial accelerometers. This software has an automatic orientation calibration procedure, an automatic erroneous orientation-estimate detection and useful visualization to help process long and short measurement periods. These automatic procedures are detailed in this paper, and two case studies are presented to showcase the usefulness of the software. The Allumo software is open-source and available online.

Traumas of locomotion system, even recovered at a great extent may change subjects’ posture and stability along time by determining an emphasis of balance or forces developed at the foot-ground contact level. In this paper we present the analysis of a subject’s case study, after a trauma in the heel area, which recovered by surgery and physical and kinetic therapy, but whose normal and/or added steps gait was changed due to the prolonged recovery time. The analysis method is based upon the information gathered from the Footscan plate sensors at the contact moment between the locomotion system (sole) and the ground. In the first part of the paper, the fundamental aspect related to the measuring of contact pressure between the human body and the ground in dynamic regime are presented, also the influence of the trunk and head posture upon this type of locomotion action. In the second part, the experimental system and the experimental development are presented, while in the final part we show the results and conclusions of this experimental research on specific case studies.

PurposeFacility structures in liquefied natural gas (LNG) plants require tremendous amounts of scaffolding to facilitate relevant industrial operation and maintenance. As such, the productivity of scaffolding operations in turnaround maintenance (TAM) has attracted much attention in recent years. In addition, health and safety issues have been recognised as a key contributor along with productivity improvement in the LNG industry. This study aims to integrate work posture analysis into value stream mapping to achieve an optimised and balanced improvement in both productivity and health and safety.Design/methodology/approachA case study approach is adopted to integrate lean and work posture analysis in a TAM site. The lean improvement is conducted through value stream mapping, and the work posture analysis is conducted through the Ovako Working Posture Analysis System method. A three-step optimisation strategy is then developed for achieving optimised performance in waste reduction and work posture improvement.FindingsIt is found that the implementation of value stream mapping can help eliminate waste in the installation process, therefore eliminating potential health and safety risks. However, health and safety of onsite workers does not always improve as lean implementation intensifies. There is an optimised erection schedule that has the lowest health and safety risk within a waste reduction target.Originality/valueIn contradiction to previous studies, which rely on qualitative assessment to identify the a positive correlation between lean and health and safety, this study reveals the distinct difference between lean attributes and health and safety attributes through a quantitative assessment and is more readily to be implemented at the site level for simultaneous improvement in lean and health and safety.

Abstract: Worldwide neurological disorders that particularly affect the central nervous system are a major health challenge, leading to deficits accompanied by neuromorphic sequelae with implications for the functional state of the body. Background: Current studies show that hemorrhagic stroke occurs mainly at a young age, often fatal as opposed to ischemic stroke that characterizes old age or an alert lifestyle, both types of strokes can result in motor sequelae and functional (mild, moderate or severe hemiparesis or haemiplegia). The peculiarity of the studied case is the coexistence of multiple comorbidities which require an interdisciplinary team to solve (neurologist, cardiologist, endocrinologist, physiotherapist, psychotherapist, aquatic therapy instructor). The aim of our paper is to demonstrate the efficiency of exercise in the aquatic environment, facilitating the recovery of the functions of the neuro-myo-arthro-kinetic apparatus as well as the cardiovascular and metabolic functions. Results: The main objective is general and muscular relaxation, re-education of external and proprioceptive sensitivity, orthostatic posture and gait reeducation, in conditions of stability and balance. Conclusions: Through the means of aquatic therapy, an attempt is made to obtain the independence of self-care in order to interrelate with the environment, to regain the ADLs, , the family and socio-professional reintegration of the patient.

Full textAbstract:
The L2 motivation self system (L2MSS) has been extensively researched in a variety of contexts, but few studies have delved into its relationship with international posture and the sustainable development of L2 proficiency in the COVID-19 era. To address this issue, we surveyed 156 English majors in China and analyzed their response data with structural equation modelling. The results show that the ideal L2 self positively predicts the L2 learning experience, while the ought-to L2 self has a negative predictive power. The international posture exerts a positive influence on the ideal L2 self and L2 experience, and a negative insignificant influence on the ought-to L2 self. The L2 experience and ideal L2 self have a positive influence on L2 proficiency, while the ought-to L2 self has a negative influence. Our results not only contribute to the generalizability of L2MSS but also deepen the understanding of possible contextual variations of L2 motivation, as well as the uniqueness in the sustainable development of English majors in China during the COVID-19 pandemic.

Background: Postural skills are fundamental in motor activities, so far no evidence of a direct relationship has been found, it is therefore recommended to consider the following directions, the higher the level of sports competition, the better the body posture; or better athletes also have a better body posture. Around the age of 11-14 years, it is a period of aggressive development, if the rapid growth of the bone system is not associated and symmetrical with the development of soft tissues serious postural deficiencies may develop in table tennis players. Methods: We used the web camera – photographic method (38) related to the Sensor Medica software that allows the acquisition of images in order to detect postural deficiencies and we considered it necessary to have a clear image of the level of technical-tactical training of female juniors III using 5 tests specific to topspin attack in order to assess the influence of body posture on such tests. Eighteen female juniors III (the mean ± SD age, height and weight were 11.1 ± 0.2 years, 147.7 ± 2.6 cm, 39.0 ± 2.0 kg). Descriptive statistical analysis was performed on the procedures for establishing the normality of data distribution, Levene's Test for Equality of Variances, the t test for independent samples. The confidence interval was set at 95% (p < 0.05), Results and Conclusions: Since Sig. (2-tailed) or p < α = 0.001 and taking into account that the confidence interval limits for the difference between the sample mean and the reference value (95% CI for the mean difference) do not contain the zero value, it is accepted that there are statistically significant differences between the shoulder inclination for the female athletes in the sample studied and the reference value. We identified that at the level of alignment between anatomical landmarks, the percentage of deficiency of the entire lot of female juniors III in the case of shoulders is 100% and at the level of PSIS is 66%, which validates several studies that stated that in this period of aggressive growth correlated with repetitive unilateral executions specific to the topspin attack lead to postural deficiencies. In terms of the influence of body posture on the quality level, we identified that Group 1 – (without PSIS imbalance) has a higher average overall efficiency of the 5 tests (11.33) compared to Group 2 (8.58), even if from a statistical point of view these differences are not significant.

Full textAbstract:
The objective of the present study was to evaluate the influence of posture on the responses of blood pressure (BP) and heart rate (HR) to the Valsalva manoeuvre (VM). Neurohumoral activation, as well as changes in intravascular and intracardiac volumes and pressures, are well known effects of orthostatic stress. These changes are likely to have significant effects on cardiovascular reflexes, such as the response to the VM. However, the influence of posture on the VM has not been intensively evaluated, except for a few studies involving small sex- and age-selected case series. We therefore investigated the effects of posture on the VM in a larger non-selected group of healthy control subjects. In 19 healthy volunteers (ten female/nine male; age range 20–72 years, mean age 43 years), two reproducible VMs (40 mmHg; 15 s) were performed after 10 min of supine rest, 10 min of sitting and 10 min of standing. HR and BP were monitored continuously. End-diastolic volume, total peripheral resistance and cardiac output were calculated at baseline for each position. We found that assuming an upright position resulted in increases in total peripheral resistance and HR, accompanied by decreases in end-diastolic volume and cardiac output. The fall in BP during early phase II and the BP overshoot during phase IV were clearly more pronounced with increasing orthostatic stress, whereas the rise in BP during late phase II remained unchanged; pulse pressure was more compressed during phase II, but higher during phase IV. The Valsalva ratio was not significantly affected, but baroreflex gain (calculated from early phase II) was significantly decreased in the upright position. While a reduced late phase II was observed on one occasion in each of the lying and sitting positions, three abnormal responses were observed during standing. We conclude that posture has a significant influence on BP responses to the VM, probably resulting from changes in the intrathoracic blood volume. Standing results in a lower rate of ‘flat-top’ responses, but also seems to reduce the specificity of this test. Sympathetic activation in the upright position seems to blunt baroreflexes, leading to similar HR responses in spite of larger changes in BP.

Full textAbstract:
Progressive dystonia with diurnal fluctuations sensitive to levodopa, also known as Segawa's disease, is a rare form of autosomal dominant extrapyramidal disease in the pediatric age group. The dystonic and Parkinson-like symptoms are the main clinical features of the disease and, characteristically but not in all cases, show a diurnal variation. They are absent or present to a lesser extent in the morning, worsening during the day. Treatment with small doses of levodopa results in remission or marked improvement of the symptomatology. We present the case of a 11 years old female patient that developed a dystonic posture in her feet that led her to a tip-toe walking pattern, since the age of 2. Diurnal fluctuations of the symptomatology were noticed by her mother. At 7 years of age she developed a left deviation of the head and an abnormal flexor posture of the left arm. In the next years the symptoms progressed and the fluctuations became less evident. At the age of 10, they were present soon after she woke up in the morning. The neurological examination disclosed a dystonic posturing of the head and left arm, a generalized rigidity of the extremities and a palpebral tremor. Laboratory examinations, including copper and ceruloplasmin, and neuro-imaging studies were negative. She was started on levodopa 150 mg/day with prompt disappearance of the symptomatology. After one-year follow-up she is symptom-free with only 100 mg/day of levodopa. No adverse effect was observed so far.

Full textAbstract:
In the past several years, grasp analysis of multi-fingered robotic hands has been actively studied through the use of posture synergies. In these grasping planning algorithms, a formulated optimization is usually performed in the hand’s low-dimensional representation together with the hand’s position and orientation. The optimization terminates at a stable grasp, often after repeated trials with different initial guesses. Furthermore, there is no guarantee that the generated grasp leads to a smooth reach-to-grasp trajectory since the grasping planning process mostly concerns hand poses with the fingers proximal to the object. A unified theoretical framework of a gradient-based iterative algorithm is hence proposed in this paper to plan a reach-to-grasp task, predicting the grasp quality and adjusting the hand’s posture synergies, position and orientation during the approaching phase to achieve a stable grasp. The grasp quality measurement is adopted from a highly efficient pseudo-distance formulation. Stable power grasp and precision pinch can be consistently and intentionally planned with different contact conditions specified in the formulation, which means that an intention for planning a power grasp would not generate a pinch result. Several numerical simulation case studies are presented to demonstrate the effectiveness of the proposed algorithm.

Individuals with severe physical and psychomotor modifications after a brain injury need measures of motor training beyond the usual physiotherapy. The effects of an intensive mobility training in the phase of late rehabilitation are reported in two case studies. The coordinative and conditional progresses were controlled by the methods of photographic anthropometry, light-track registration, and bicycle ergometry. Improvements were found in posture and dynamic endurance in correlation with the generally improving motor control. Tests of everyday relevant movements revealed qualitative progresses in the sense of increased motor precision and economy.

The worldwide health impact of the COVID-19 epidemic has been felt all across the world, mostly due to respiratory issues, but many additional signs such as cardiac manifestations and different thromboembolisms have also been observed. Case Summary. We provide you with a 48-year-old female patient with COVID-19 pneumonia following a severe infection, who developed Unstable Angina due to coronary thrombosis. She has a history of hypertension and obese posture. No diabetes, hypercholesterolemia, or smoking habit had been recorded. And she still has regular menstrual cycle. Around a month prior to being referred to our hospital, this patient has been admitted to ICU of satellite hospital. She was treated with ventilator and discharged around a week before she was admitted to our Emergency Department. She had typical chest pain with ST-segment depression ECG at antero-septal area. PCI was performed and a large thrombosis was found at LAD artery. Discussion: Many studies have showed that COVID-19, through various ways, has developed thromboembolism both in arteries and venous system. The actual process of thrombus development in the coronary arteries is unknown, however, it is thought that pro-inflammatory cytokinesis released by the body, which stimulates the coagulation cascade and prevent fibrinolysis, are the major cause. This condition that leads to hypercoagulable state which eventually makes an increased risk of thromboembolism.

Background: Medial tibial stress syndrome (MTSS) is a common diagnosis. Several studies have demonstrated that excessive static navicular drop (ND) is related to the diagnosis. However, no studies have yet investigated ND and the velocity of ND during dynamic conditions. The aim of this study was to evaluate ND characteristics in patients with MTSS in dynamic and static conditions. Methods: In a case-control study, 14 patients diagnosed as having MTSS were included from an orthopedic outpatient clinic. A control group consisting of 14 healthy participants was matched regarding age, sex, and typical sporting activity. Navicular drop was evaluated during treadmill walking by a two-dimensional video analysis. Static foot posture, static ND, dynamic ND (dND), and velocity of dND were compared. Results: The two groups were comparable in relation to age, sex, height, weight, and foot size. No significant difference was found in static foot posture. Static ND showed a mean difference of 1.7 mm between the groups (P = .08). During treadmill walking, patients with MTSS had, on average, a 1.5-mm-larger dND (P =.004) and a 2.4-mm/sec-larger mean velocity of dND (P = .03). Conclusions: Patients with MTSS display a larger ND and a higher ND velocity during treadmill walking. Increased ND velocity may be important to this condition. Future studies should include velocity of dND to investigate the mechanisms of dND in relation to overuse injuries. (J Am Podiatr Med Assoc 102(3): 205–212, 2012)

Full textAbstract:
IntroductionPisa Syndrome or pleurothotonus is a form of dystonia and often can arise as a side effect of antipsychotic treatment conditioning high morbidity and limiting management options. Despite the fact that the precise mechanism remains unclear, a neurochemical imbalance in dopaminergic and cholinergic transmission but also in serotoninergic and noradrenergic transmission can be a possible pathophysiologic mechanism, which can lead to changes in the axial axis with abnormal posture and marked lateral trunk flexion and abnormal gait.ObjectivesRegarding a clinical case, the authors intend to review the relevant and current literature on the relationship between psychotropic drugs and Pisa Syndrome.MethodsDescription of a clinical case by consulting databases of current and scientifically relevant articles.ResultsThe clinical case reports a 48-year-old woman with a history of HIV and Substance Use Disorder, hospitalized for unspecific behavioral changes, characterized by mood changes, self-referential, persecutory and somatic delusional ideas, and delusions of the control of thought. She was medicated with antipsychotics and mood stabilizers, with subsequent development of an acute-onset dystonic condition, characterizing the Pisa Syndrome. In this context, the dose of antipsychotics was lowered and anticholinergics were introduced, with progressive improvement of the clinical picture.ConclusionsPisa Syndrome, previously seen as a rare adverse effect, can occur as a dystonic reaction related to the use of psychotropic drugs, so its use should be judicious. Further studies are needed to understand the extent of this association and its pathophysiological mechanisms in order to guide more rigorous therapeutic lines.DisclosureNo significant relationships.

Full textAbstract:
Recent studies have confirmed the relationship between head posture, mandibular position and visual focusing. A case-controlled study was conducted to assess the occurrence of ocular convergence defects between subjects with functional mandibular latero-deviation and healthy subjects in pediatric age. Sixty subjects (the study group) presented mandibular latero-deviation classified as functional according to the use of a clinical examination and frontal and basal tele-radiography. Sixty subjects without functional mandibular laterodeviation (control group) were selected randomly from all subjects seeking pediatric dental care and matched by gender and age to study group. All one hundred and twenty subjects were submitted to orthoptic tests performed by the same operator. These results seemed to confirm that in mandibular latero-deviation subjects ocular convergence defects occurred in greater frequency than in controls underlining the importance of role of pediatric dentistry among interdisciplinary cooperation.

Full textAbstract:
ABSTRACT Death-feigning behaviour occurs when the animal simulates a state of immobility. This behaviour is described for some lizard families, among them the family Gymnophthalmidae with only one record. Iphisa elegans is a diurnal and terrestrial Amazonian gymnophtalmid lizard. It has cryptic behavior and moves rapidly on the ground, hindering observations of its behavior. We report a case at the Comodoro Municipality, Mato Grosso State, Brazil. An adult male of I. elegans, when manipulated, turned its venter up and put itself in a death-feigning posture. This species is preyed upon by birds, snakes and other lizards¸ possibly behaving this way when the cryptic behaviour or escape attempt fails. More studies are necessary to evaluate the efficiency of this behaviour, as well as its frequency of occurrence, using individuals of both sexes. We also suggest to evaluate if the orange venter of males could have any antipredation advantage.

Summary. A retrospective analysis of case histories and radiographs of 138 patients with hip-lumbar syndrome who underwent hip joint replacement in the clinic of orthopedics and adult traumatology at the ITO NAMS of Ukraine was carried out. It has been determined that the variant of vertical posture, acting on the morphogenesis of coxarthrosis, determines the rate of its progression. It was determined that in the presence of hip-lumbar syndrome, a moderate form of CA progression most often occurs, regardless of the type of lordosis. The slow rate of progression of coxarthrosis is characteristic of hyper- and normolordosis. Hypolordosis is statistically significant (p < 0,05) characterized by a faster course of the pathological process in the hip joint than other types of lordosis. The studies will contribute to the further development of the clinical diagnostic and therapeutic algorithm for patients with hip-lumbar syndrome.

AbstractThis article aims to highlight stroke considerations in the evaluation and management of dysphagia. Although dysphagia was previously thought to occur only following brainstem or bilateral cortical strokes, the development of brain imaging and dynamic swallowing studies has revealed small, unilateral supratentorial strokes can produce dysphagia. In this article, screening, evaluation, and management of dysphagia are outlined, as well as the clinical decision making that occurs when taking into account cognitive and communication deficits that may be present. For the clinical swallow examination, chart review, interview, informal evaluation of cognition and communication, observation of posture, oral cavity inspection, cranial nerve examination, and the direct swallowing assessment are reviewed along with tailoring of each according to the deficits observed. Specific compensation and rehabilitation strategies are discussed along with how cognitive and communication deficits can guide the clinician's decision-making process to select an appropriate plan of care. A case study is provided to synthesize the process into a real-world scenario.

Full textAbstract:
Whenever a human body stands on a platform like a bus, train, etc then the waveform, frequency, amplitude, and duration due to vibrations can be changing and these variations produce some advantages in muscles and bone mineral density whereas high acceleration of platform viewed as dangerous. The reason behind this is the resonance of the human body that depends upon some factors: the seat surface material, the posture, vibration magnitude, and frequency, etc. In this study, modal and harmonic response analysis has been performed to calculate the natural frequencies of Indian human male subjects in standing posture conditions under un-damped and damped free vibration conditions. With the help of this, we are capable to know how these vibrations affect our muscles, bones, joints, etc. Joint studies of the human body help us to replace body joints in case of any serious injury or in emergency and multibody dynamics, modal analysis, and harmonic response play crucial roles in these effects. This study shows the vibration effects of transmissibility and stresses on the knee joints and neck joints of the human body. For this purpose, a revolute joint is separately designed and fixed at the location of joints in human subjects to understand the effect of these vibrations. The results are determined in this study are within the frequency range of 0-20 Hz.

Full textAbstract:
Background Altered spinal postures and altered motor control observed among people with non-specific low back pain have been associated with abnormal processing of sensory inputs. Evidence indicates that patients with non-specific low back pain have impaired lumbo-pelvic proprioceptive acuity compared to asymptomatic individuals. Objective To systematically review seated lumbo-pelvic proprioception among people with non-specific low back pain. Methods Five electronic databases were searched to identify studies comparing lumbo-pelvic proprioception using active repositioning accuracy in sitting posture in individuals with and without non-specific low back pain. Study quality was assessed by using a modified Downs and Black’s checklist. Risk of bias was assessed using an adapted tool for cross-sectional design and case–control studies. We performed meta-analysis using a random effects model. Meta-analyses included subgroup analyses according to disability level, directional subgrouping pattern, and availability of vision during testing. We rated the quality of evidence using the GRADE approach. Results 16 studies met the eligibility criteria. Pooled meta-analyses were possible for absolute error, variable error, and constant error, measured in sagittal and transverse planes. There is very low and low certainty evidence of greater absolute and variable repositioning error in seated tasks among non-specific low back pain patients overall compared to asymptomatic individuals (sagittal plane). Subgroup analyses indicate moderate certainty evidence of greater absolute and variable error in seated tasks among directional subgroups of adults with non-specific low back pain, along with weaker evidence (low-very low certainty) of greater constant error. Discussion Lumbo-pelvic proprioception is impaired among people with non-specific low back pain. However, the low certainty of evidence, the small magnitude of error observed and the calculated “noise” of proprioception measures, suggest that any observed differences in lumbo-pelvic proprioception may be of limited clinical utility.

Body image involves perceptions, attitudes, and beliefs concerning one’s body, while body schema involves the sensorimotor capacities to control movement and posture. A review study is needed to obtain sufficient data to determine the effect of body awareness on the normal development of children. This study is a systematic review of interventions related to body awareness among typically developing children. Studies focusing on interventions related to body awareness from 2010 to 2021 were analyzed and extracted from four major scientific databases, and the three that met the inclusion criteria were analyzed. Methods were analyzed by frequency, and the results were analyzed by calculating effect sizes. Two studies involved a nonrandomized two-group design and a single-case experimental study. Two studies targeted early childhood, and one study focused on middle childhood. This review indicates that determining the effectiveness of interventions related to body awareness is necessary for typically developing children because body awareness is a potential influencing factor in their development. Additional research is needed to determine the effectiveness of body awareness assessment tools and interventions.
