Resumen
Human controls dozens of muscles for different hand postures in a coordinated manner. Such coordination is referred to as a postural synergy. Postural synergy has enabled an anthropomorphic robotic hand with many actuators to be applied as a prosthetic hand and controlled by two to three channels of biological signals. Principle component analysis (PCA) of the hand postures has become a popular way to extract the postural synergies. However, relatively big errors are often produced while the hand postures are reconstructed using these PCA-synthesized synergies due to the linearity nature of this method. This paper presents a comparative study in which the postural synergies are synthesized using both linear and nonlinear methods. Specifically, the Gaussian process latent variable model (GPLVM), as a nonlinear dimension reduction method, is implemented to produce nonlinear postural synergies and the hand postures can then be reconstructed from the two-dimensional synergy plane. Computational and experimental verifications show that the posture reconstruction errors are greatly reduced using this nonlinear method. The results suggest that the use of nonlinear postural synergies should be considered while applying a dexterous robotic hand as prosthesis. Versatile hand postures could be formed via only two channels of bio-signals.

Resumen
Workers from various industries can be exposed to musculoskeletal disorders (MSDs) risks in the workplace. Most cases of MSDs happen because of the accumulation of repetitive bad postures. Postural analysis can be done to implement changes that minimize MSDs risks in the workplace. The rapid entire body assessment (REBA) method provides an easy and fast measurement to analyze various postures. The accuracy of REBA assessments from observations is not good enough due to the limitations of human vision. The input of photo-based postural analysis also has a lot of error potential and takes up even more time. Therefore, this study aims to design a tool to do body posture measurements accurately and quickly. The Arduino-based postural analysis tool measures the position of several body segments, which are then used as the input of REBA in real time. The acceleration of each body segment recorded by the MPU6050 will be processed as displacement data and used to analyze the posture. The posture measurements detected by the tool is then used as input for REBA assessment. The device's accuracy was tested by comparing the photo-based postural analysis result to the postural analysis result of the tool. The reliability of the device was tested by Cronbach's Alpha method. The Cronbach's Alpha value of normal standing posture is 0.692, and the extreme posture's Cronbach's alpha value is 0.537. Multiple postures can be recorded at once using the tool. The tool can capture and assess multiple postures in approximately 6 minutes.

Resumen
The analysis of the postural attitude of workers during the interaction with workstation’s elements and working environment is essential in the evaluation and prevention of biomechanical overload risk in workplaces. RULA (Rapid Upper Limb Assessment) and REBA (Rapid Entire Body Assessment) are the two easiest methods for postural risk assessment in the workplace. Few studies investigated postural risk in forestry sector with regard to human–machine interaction, in particular manually fed wood-chippers. The aim of this study was to evaluate the postures assumed by an operator during the manual feeding of a wood-chipper, and to compare RULA and REBA, in order to identify the more effective and appropriate method for the assessment of the risk of biomechanical postural overload. The results pointed out several postural issues of the upper limbs, and showed that RULA is a more precautionary method to protect operator’s health during the targeted tasks. Implications to improve the human–wood-chipper interaction are discussed.

Resumen
This paper presents a new method to empirically investigate the effects of task factors on three-dimensional (3D) dynamic postures during seated reaching movements. The method relies on a statistical model in which the effects of hand location and those of various task factors on dynamic postures are distinguished. Two statistical procedures are incorporated: a regression description of the relationship between the time-varying hand location and postural profiles to compress the movement data, and a series of analyses of variance to test the hypothesized task effects using instantaneous postures with prescribed hand locations as dependent measures. The use of this method is illustrated by an experiment which examines two generic task factors: 1) hand movement direction, and 2) motion completion time. The results suggest that the hand motion direction is a significant task factor and should be included as an important attribute when describing or modeling instantaneous postures. It was also found that the time to complete a motion under a self-paced mode was significantly different from a motivated mode, but the time difference did not significantly affect instantaneous postures. The concept of an instantaneous posture and its usage in dynamic studies of movements are discussed. Some understanding of human postural control as well as the implications for developing a general dynamic posture prediction model also are presented.

Resumen
This narrative review delves into the historical and evolutionary aspects of human bipedal upright posture, tracing its development from anthropological perspectives to modern postural analysis methods. It examines the multifaceted factors influencing the evolution of upright posture in human ancestors, challenging the notion of a singular cause. The review highlights various environmental and social hypotheses, such as the need for gathering food, self-defense, or tool use, which may have contributed to this significant evolutionary shift. The concept of posture has been interpreted differently across historical periods, reflecting the prevailing cultural and scientific understanding. From Aristotle’s view of upright posture as a divine gift to Johann Gottfried Herder’s perspective of it as a distinguishing human characteristic from animals, and to the more contemporary views of Henry and Florence Kendall, the evolution of the concept mirrors the changing paradigms in human thought. The development of methods for evaluating posture is also a key focus. The review traces the journey from the introduction of the plumb line in the 1850s, a simple yet effective tool for assessing spinal asymmetries, to the advent of the Adams test and the scoliometer, which revolutionized scoliosis diagnosis. Today, advanced techniques like rasterstereography and AI-based methods offer sophisticated, non-invasive means for detailed posture analysis, minimizing errors and maximizing efficiency. The review emphasizes the ongoing importance of posture in the context of overall health, underscoring the adage of a healthy mind in a healthy body. It illustrates how the study of posture, from its evolutionary roots to modern analytical tools, remains a vital aspect of understanding human health and well-being.

Resumen
Human upright posture exhibits an everlasting oscillatory behavior of complex nature, called as human postural sway. Variations in the position of the Center-of-Pressure (CoP) were used to describe the human postural sway. In this study
CoP data, which has experimentally been collected from 28 different subjects (14 males and 14 females with their ages ranging from 6 to 84), who were divided into 4 groups according to their ages has been analyzed. The data collection from each of the subjects was performed in 5 successive trials, each of which has lasted for 180-seconds long. Linear analysis methods such as the variance/standard deviation, Fast Fourié
r Transformation, and Power Spectral Density estimates were applied to the detrended CoP signal of human postural sway. Also the Run test and Ensemble averages methods were used to search for stationarity and ergodicity of the CoP signal respectively. Furthermore, in order to reveal the nonlinear characteristics of the human postural sway, its dynamics were reconstructed in m-dimensional state space from the CoPx signals. Then, the correlation dimension (D2) estimates from the embedded dynamics were calculated. Additionally, the statistical and dynamical measures computed were checked against any significant changes, which may occur during aging. The results of the study suggested that human postural sway is a stationary process when 180-second long biped quiet stance data is considered. In addition, it exhibits variable dynamical structure complex in nature (112 deterministic chaos versus 28 stochastic time series of human postural sway) for five successive trials of 28 different subjects. Moreover, we found that groups were significantly different in the correlation dimension (D2) measure (p&
#8804
0.0003). Finally, the behavior of the experimental CoPx signals was checked against two types of linear processes by using surrogate data method. The shuffled CoPx signals (Surrogate I) suggested that temporal order of CoPx is important
however, phase-randomization (Surrogate II) did not change the behavioral characteristics of the CoPx signal.

Resumen
L’analyse de la stabilité posturale chez l’homme a fait l’objet, ces dernières années, d’un intérêt grandissant au sein de la communauté scientifique. Le système postural permet de maintenir la stabilité du corps humain en posture statique ou dynamique. Cette capacité à maintenir cette stabilité devient critique dans le cas des sujets Parkinsoniens. La maladie de Parkinson a en effet une forte incidence sur la stabilité posturale. Un moyen efficace pour évaluer l’équilibre postural consiste à analyser les déplacements dans le plan horizontal du centre de pression du corps humain en posture orthostatique ; les trajectoires mesurées dans la direction medio-latérale (ML) et la direction Antéro-postérieure (AP) sont appelées signaux stabilométriques. Dans cette thèse, nous visons le développement de méthodes efficaces pour l’analyse de l’équilibre en posture orthostatique sous différentes conditions liées à l’entrée visuelle (yeux ouverts/yeux fermés), la position des pieds (pieds joints/pieds écartés) et en considérant d’autres facteurs comme le genre et l’âge. Dans ce cadre, nous proposons, tout d’abord, une méthode exploitant la variante EEMD (Ensemble Empirical Mode Decomposition) de la décomposition en modes empiriques (EMD) et l’analyse de la diffusion du stabilogramme. Dans le contexte du diagnostic de la maladie de Parkinson, la discrimination entre sujets sains et sujets Parkinsoniens est très importante, de même que l’évaluation du stade de la maladie pour les sujets atteints. Dans ce cadre, deux méthodes sont proposées. La première consiste tout d’abord en une extraction et sélection de caractéristiques temporelles et spectrales, à partir des signaux stabilométriques brutes ou des modes de fonctions intrinsèques dérivés de la décomposition EEMD. Des méthodes standards de type KNN, CART, RF et SVM sont ensuite appliquées pour reconnaitre les sujets Parkinsoniens. La deuxième méthode proposée, est une approche de classification qui repose sur l’emploi de HMMs construits en utilisant les signaux stabilométriques brutes dans les directions ML, AP et ML/AP. Enfin, une dernière méthode est proposée pour la segmentation automatique des signaux stabilométriques sous différentes conditions (entrée visuelle, position des pieds). Pour ce faire, un modèle de régression régi par une chaine de Markov cachée (HMMR) est utilisé pour détecter automatiquement les variations des structures des signaux stabilométriques entre ces conditions. Les résultats obtenus montrent clairement la supériorité des performances des méthodes proposées par rapport aux approches standards, aussi bien, en termes d’analyse de l’équilibre postural que de diagnostic de sujets Parkinsoniens
Recently, human balance control analysis has received an increasing interest from the research community. The human postural system maintains the stability of the body both in the static posture (quiet standing) and during locomotion. This ability to maintain stability becomes hard with aging and Parkinson's disease (PD) subjects. PD has a strong effect on postural stability during quiet standing situations, and during locomotion. One effective way to assess human stability is to analyze the center of pressure (CoP) displacements of the human body during quiet standing. The recorded CoP displacements in quiet standing are called stabilometric signals. This thesis aims to develop efficient approaches to analyze the human postural stability in quiet standing under visual and feet position conditions, as well as under age and gender. This is achieved using Empirical Mode Decomposition (EMD) method and stabilogram-diffusion technique. In the other part, the discrimination between healthy and PD subjects is very important for diagnosing Parkinson's disease, as well as for evaluating the disease level of the patient. In this context, two approaches are proposed; the first approach consists of an EMD-based temporal and spectral feature extraction from the stabilometric signals. The second approach is based on a Hidden Markov Model (HMM) using the raw stabilometric signals. The HMM model is an efficient tool to analyze temporal and sequential data. Another approach is proposed in order to segment the stabilometric signals according to the visual and feet position conditions. This is achieved using a Hidden Markov Model Regression (HMMR)-based approach. This study help clinicians to better understand the motor strategies used by the subjects during quiet standing and may guide the rehabilitation process. The obtained results clearly show high performances of the proposed approaches with respect to other standard approaches in both postural stability analysis and discrimination healthy from PD subjects

Resumen
Postural distortion of human bite marks on skin occurs when photographing a bite mark in a body position other than the position of the body at the time of biting. Postural distortion in the bite mark may introduce significant changes in both the shape and size of the recorded marks. As a result, the analysis of the marks may be hindered and a proper comparison between the bite mark and the causal dentition may be precluded. Therefore, a method by which postural distortion in a bite mark photographic record can be evaluated and eliminated with minimal operator subjectivity is required. This study describes the development of an objective technique for evaluating postural distortion in bite mark photographic records and for minimising postural distortion during photography of bite marks. The source for developing these techniques was provided by digitally analysing the symmetry of dental arches in a defined population including males and females (236 subjects) whose ages ranged between 20 and 30 years. The analysis resulted in quantifying a mathematical relationship between the biting edges of each homologous pair of the anterior teeth and specified reference lines. The validity of the analytical method of dental arch symmetry is discussed. The developed techniques were applied to posturally distorted (test) bite marks. The results demonstrate the validity of the developed techniques in determining postural distortion and recording correct images (shown to resemble the biters dentition) of the test bites. Suggestions for further work are proposed.

Resumen
This thesis investigates on clinical applicability of a novel sensing technology in the areas of postural steadiness and stroke assessment. The mechanically simple Distributive Tactile Sensing approach is applied to extract motion information from flexible surfaces to identify parameters and disorders of human movement in real time. The thesis reports on the design, implementation and testing of smart platform devices which are developed for discrimination applications through the use of linear and non-linear data interpretation techniques and neural networks for pattern recognition. In the thesis mathematical models of elastic plates, based on finite element and finite difference methods, are developed and described. The models are used to identify constructive parameters of sensing devices by investigating sensitivity and accuracy of Distributive Tactile Sensing surfaces. Two experimental devices have been constructed for the investigation. These are a sensing floor platform for standing applications and a sensing chair for sitting applications. Using a linear approach, the sensing floor platform is developed to detect centre of pressure, an important parameter widely used in the assessment of postural steadiness. It is demonstrated that the locus of centre of pressure can be determined with an average deviation of 1.05mm from that of a commercialised force platform in a balance application test conducted with five healthy volunteers. This amounts to 0.4% of the sensor range. The sensing chair used neural networks for pattern recognition, to identify the level of motor impairment in people with stroke through performing functional reaching task while sitting. The clinical studies with six real stroke survivors have shown the robustness of the sensing technique to deal with a range of possible motion in the reaching task investigated. The work of this thesis demonstrates that the novel Distributive Tactile Sensing approach is suited to clinical and home applications as screening and rehabilitation systems. Mechanical simplicity is a merit of the approach and has potential to lead to versatile low-cost units.

Texto completo
Resumen
Anticipatory Postural Adjustments (APAs) are a crucial aspect of the voluntary movement organization, being fundamental in stabilizing both the whole-body (inter-limb APAs) and its segments (intra-limb APAs). Until now, only a few works investigated the neural structures involved in APAs programming, by correlating neurological diseases with APAs changes. This approach clarified not only the knowledge regarding these pathologies, but also the relationships between these structures and the APA command. So, to enrich the comprehension about the neural network generating and influencing APAs, this thesis is focused on two aspects. The first part investigated the role of two subcortical structures, basal ganglia and cerebellum, in APAs organization. In particular, it was analyzed (i) how intra-limb APAs stabilize the arm and the forearm, when flexing the index-finger, in patients with basal ganglia dysfunction, as well as (ii) the inter-limb APAs associated to gait initiation in children with cerebellar ataxia. Results showed that basal ganglia seem to be involved in APA control, since the normal pattern of intra-limb APAs is disrupted in parkinsonian patients. On the other hand, the role of the cerebellum as a timing-machine was confirmed, since several alterations were found in the temporal organization of inter-limb APAs in ataxic vs. healthy children. Considering recent studies showing that basal ganglia and cerebellum are reciprocally interconnected and that the cerebellum exerts a functional compensatory activity in parkinsonian patients, it could be interesting to address future studies to inquire a reciprocal compensatory role of basal ganglia in cerebellar disease. The second part dealt with the possible influence of cognitive processes on APA control. To achieve this goal, a cerebellar area with a well-known cognitive role, Crus I-II, was examined. In this context, a protocol of Magnetic Resonance Spectroscopy was developed, able to characterize and quantify metabolites in a cerebellar area of interest. The protocol was validated in healthy subjects and could be used in future investigations of neurological diseases affecting postural and motor control. Finally, the Parietal Operculum (PO) activity was studied. This is a cortical sensory-motor integration center, notably involved in a multimodal network. So, intra-limb APAs associated to index-finger flexion were analyzed in healthy subjects before, during and after modulating the contralateral PO (coPO) excitability by anodal and cathodal transcranial Direct Current Stimulation (tDCS). Since no significant effects were found on intra-limb APAs amplitude and timing, the coPO does not seem to be involved in APA control. However, future studies should address the possible influence of both POs by bilateral tDCS.

Resumen
This chapter continues to develop the enriched conception of embodiment that fits an enactivist approach to cognition. It discusses recent biological and evolutionary theory concerning the upright posture and the role of human hands, which are free not only to reach and grasp, but also to contribute to the shaping of human rationality. The notion of affordance space can help to discriminate between what changes (of brain, body, environment) belong to evolution as opposed to development or culture, or individual experience. This analysis relates to the pragmatic concept of manipulatory area (Mead), which contributes to an understanding of the roles of tools, technology, and intersubjectivity in cognition.

Resumen
This chapter discusses human figurines from later Iranian prehistory and pays special attention to the figurines from the sites of Tepe Sarab, Zaghe, Hajji Firuz, and Choga Mish. It also presents an overview of human figurines produced at other Iranian sites. Drawing on the analyses of the figurines’ morphologies, materials used, production processes, contexts of disposition, breakage patterns, bodily details, and representation of attire, these figurine industries from the Neolithic and Chalcolithic periods of Iran have the potential to enlighten us about communal and private matters, bodily concerns through the life cycle, and issues related to identity constructions via dress, posture, and corporeality.

Resumen
The stability of the human spine in compression has attracted a considerable amount of attention in recent years. The passive ligamentous thoracolumbar and lumbar spines are known to exhibit large displacements or hypermobility (i.e., instability in an imperfect column) under compression loads <100N. Since such compression loads are only a small fraction of those supported by the spine even in regular daily activities, let aside the manual material handling tasks, the question arises as to how the spine is stablized in vivo? Various stabilizing mechanisms have been proposed and investigated; wrapping loading [Shirazi-Adl and Parnianpour, 2000], postural adaptations [Shirazi-Adl and parnianpor, 1999], intra-abdominal pressure [Cholewicki et al, 1999] and muscle activation/coactivation [Bergmark, 1989; Crisco and Panjabi, 1991]. In this work, a novel kinematics-based methad [Shirazi-Adl et al., 2002] is first applied to compute muscle forces and internal loads in standing postures under gravity with or without 200N loads held either on sides or close to the body in front. The stability of the system under given loads and prescribed postures is sudsequently examined using both linear bucking analysis based on the deformed configurations and nonlinear analysis while employing a liner stiffness-force relationship for muscules [Bergmark, 1989; Crico and Panjabi, 1991]. The relative accuracy of foregoing methods in stability analysis of some sample structures is also investigated. Moreover, the effect of co-activity on stability of the spine in neutral postures is studied.

Resumen
Adolescent idiopathic scoliosis (AIS) is the complex three-dimensional deformity of the spine. AIS is commonly accompanied by postural alterations and imbalance problems. Adolescents with a spinal curvature between 6-20 degrees are defined as being in the early stages of scoliosis. Generally, bracing treatment with a hard brace is only recommended for adolescents with a spinal curvature between 21-40 degrees, while observation with periodical re-examination of the spine is suggested for cases of early scoliosis. Nevertheless, more treatment options could be provided to adolescents with early scoliosis as opposed to only observation. Therefore, a posture correction girdle has been developed with the aim to reduce posture imbalance problems and the possibility of spinal curve progression. In this study, the immediate effects of the posture correction girdle on four adolescents with early scoliosis are reported. Each subject undergoes a 2-hour trial of the girdle. Data collection is carried out before and after the trial by using radiographic imaging and three-dimensional body scanning. To evaluate the immediate effects of the posture correction girdle, comparisons are made pre and post results. Apart from the radiographic analysis, the changes of the postural angles in the frontal, horizontal, and sagittal planes during standing are also considered. The evaluation results show that the girdle has positive effects on the subjects. Two of them show a significant reduction in their spinal curve, while all of them reduce their postural imbalance during the time that the posture correction girdle is worn.

Resumen
In this paper the methodology for assessing interactions between eye movements and induced emotional level was present. It was found during analyzes the bio-behavior of young people some corresponding changes in eye movements when they are surprised by the positive or negative emotions. This behavioral change is accentuated and manifests itself on the eye level but also by changing the biomechanical postural stability. By this research was developed a procedure for evaluating the postural response correlated with ocular motility recordings and facial temperature variations, when subjects were induced them, in separate way, the same positive / negative emotions. In the first part they are analyzed static and dynamic characteristics of the human body (stability, posture) to establish normal bio-behavior and also the facial temperature variations in normal environmental conditions. Also was analyzed the eye movement and facial temperature variations in the same conditions. In the second part of the paper, the experimental setup and recordings are developed and presented. Experimental tests conducted on a sample of 16 young human subjects, according to the procedure and methodology developed is presented in the third part of the paper. The paper presents some important aspects of the experimental use assessment methodology and also results on a sample of young people to understand and to correlate the eye movements with the postural bio-behavior during induced emotions (calculus of correlation index in different emotional situation). At the end of the work are reviewed and analyzed primary results shown, during recordings as the basis for future research.

Resumen
Abstract Understanding the mechanisms behind human balance has been a subject of interest as various postural instabilities have been linked to neuromuscular diseases (Parkinson’s, multiple sclerosis, and concussion). This paper presents a classification method for an individual’s postural stability and estimation of their neuromuscular feedback control parameters. The method uses a generated topological mapping between a subjects experimental data and a data set consisting of time series realizations generated using an inverted pendulum mathematical model of upright balance. The performance of the method is quantified using a time series realizations with known stability and neuromuscular control parameters. The method was found to have an overall sensitivity of 85.1% and a specificity of 91.9%. Furthermore, the method was most accurate when identifying limit cycle oscillations with a sensitivity of 91.1% and a specificity of 97.6%. Such a method has the capability of classifying an individual’s stability and revealing possible neuromuscular impairment related to balance control, ultimately providing useful information to clinicians for diagnostic and rehabilitation purposes.

Resumen
Review question / Objective: This study aimed to conduct a meta-analysis of Tuina in the treatment of Sciatica to clarify its efficacy and safety. Condition being studied: Sciatica is one of the common pain symptoms in the human body, also known as radiating leg pain. Sciatica is increasingly occurring due to poor posture and lack of physical exercise all over the world. At present, many studies have indicated that Tuina can improve the clinical symptoms and functional status of sciatica. However, there is currently no relevant systematic review to evaluate and report this clinical scientific issue. Consequently, this study will conduct a meta-analysis on the effectiveness and safety of Tuina therapy for sciatica.
