Abstract:

SUMMARYWhile Sit-to-Stand and Stand-to-Sit are routine activities and are crucial pre-requisites to walking and running their underlying dynamics are poorly understood. Furthermore, the potential for using these movements to regenerate energy in energy-sensitive devices such as orthoses, prostheses and humanoid robots has never been examined. Insights in this domain can lead to more energy-efficient prosthesis, orthosis and humanoid robot designs.OBJECTIVES: The objectives are two-fold: first, to determine how much energy can be regenerated during standard movements related to transitions between sitting and standing on a scale humanoid model and second, to determine if the chosen actuator could produce better results if the gear ratio were modified. This manuscript's main contribution to the literature is by showing which joint provides the most regenerative effect during transitions between sitting and standing.MODEL DESIGN AND IMPLEMENTATION: Joint trajectories from existing biomechanics trials of sitting and standing transitions were fed into a 1/10 scale model of a humanoid robot. The robot model, developed in MapleSim, is comprised of standard and off-the-shelf subcomponents, including amplifier, NiMH battery and Robotis Dynamixel RX-28 actuators.RESULTS: Using the RX-28 actuator, the ankle, knee and hip joints all show a degree of regenerative effects, the hip demonstrates the most dramatic levels during the transition from standing to sitting. This contrasts with recent publications which show that the knee has the most important regenerative effects during walking and running. It is also found that for under 3 degree trajectory error the regenerative effect is best for all joints when the gear ratio is increased from the RX-28's 193:1 value to a value of approximately 760:1 for the ankle, 630:1 for the knee and 600:1 for the hip.CONCLUSIONS: During transitions between sitting and standing the greatest potential for regeneration occurs in the hips. Therefore, systems designed to implement regenerative effects between sitting and standing need to include subsystems at the hip for maximum regenerative effects.

Abstract:

SUMMARYIn this paper, we introduce a lower extremity exoskeleton CUHK-EXO that is developed to help paraplegic patients, who have lost the motor and sensory functions of their lower limbs to perform basic daily life motions. Since the sit-to-stand and stand-to-sit (STS) motion is the first step for paraplegic patients toward walking, analysis of the exoskeleton's applicability to the STS motion assistance is performed. First, the human-exoskeleton system (HES) is modeled as a five-link model during the STS motion, and the center of pressure (COP) on the ground and center of gravity of the whole system are calculated. Then, a description of the CUHK-EXO hardware design is presented, including the mechatronics design and actuator selection. The COP position is an important factor indicating system balance and wearer's comfort. Based on the COP position, a trajectory online modification algorithm (TOMA) is proposed for CUHK-EXO to counteract disturbances, stabilize system balance, and improve the wearer's comfort in the STS motion. The results of STS motion tests conducted with a paraplegic patient demonstrate that CUHK-EXO can provide a normal reference pattern and proper assistive torque to support the patient's STS motion. In addition, a pilot study is conducted with a healthy subject to verify the effectiveness of the proposed TOMA under external disturbances before future clinical trials. The testing results verify that CUHK-EXO can counteract disturbances, and help the wearer perform the STS motion safely and comfortably.

Abstract:

Background It is unknown whether self-initiated sit-to-stand training with an assistive device is effective to regain the independence of sit-to-stand in stroke survivors. Objective To compare the effectiveness of self-initiated sit-to-stand training with an assistive device with manual sit-to-stand training. Design Parallel randomized controlled, assessor-blinded trial between January 2015 and May 2018. Randomization was performed by drawing lots to allocate treatment groups. Setting A rehabilitation hospital in Hong Kong. Participants 69 participants in medical wards with unilateral hemiparetic stroke. A total of 52 participants fulfilled the study requirements. Intervention Ten sessions of intervention with conventional physiotherapy program followed, by self-initiated sit-to-stand training with an assistive device, or by manual sit-to-stand training. Main outcome measure Number of participants regained the independence of sit-to-stand, sit-to-stand test from the Balance master® and Five-repetition sit-to-stand test. Results 69 participants (intervention, n = 36; control, n = 33) were randomized (mean age, 69.8 years (SD: 10.6), mean post-stroke days 18.6 (SD: 16.0)). Seventeen participants had not completed 10 sessions of training, leaving 52 ( n = 26; n = 26) participants for per protocol analysis. Eighteen participants in the intervention group and 10 participants in the control group had regained the independence of sit-to-stand (Phi and Cramer’s V: –0.31 and 0.31). The participants in the intervention group were faster to complete the Five-repetition sit-to-stand test than the control group (32.7 sec (SD: 1.93) versus 48.4 sec (SD, 6.8); 95% confidence interval, –30.8 to –0.7; p < 0.05). No adverse side effects occurred during and after the training across groups. Conclusions Self-initiated sit-to-stand training with an assistive device may have positive effects on speeding up regaining the independence of sit-to-stand on sub-acute stroke survivors.

Abstract:

Strengthening exercise for lower limbs is required in elderly. Repeated sit to stands could improve lower limbs strength, reduce limitations, and fall. The researchers developed a Sit to Stand Trainer, a device that assists and offers variable levels of weight support for users to stand. It was validated by comparing the kinematics and the kinetics between 2 experimental conditions; the movement that was assisted by Sit to Stand Trainer (STST) and the natural movement that was unassisted by Sit to Stand Trainer (No STST). This study is an Experimental Design using Pearson Correlation Coefficient. The time span of the observed movement was 2.5 s for all trials. The results in kinematics showed significant similarity in trunk, hip, knee, ankle angles and angular velocities including speed and distance of head between No STST to STST (P = 0.000). However, in kinetics, the maximum of vGRFs showed significant decrease in STST compared to No STST (P = 0.000). This represent that this device produces natural movement and speed. It also supports and helps to reduce the body weight that contacted to the ground in order to stand up easier. Thus, therapists could possibly consider this device for training in clinical practice. This research was studied within 6 weeks into training with Sit to Stand Trainer. This part of the study is a Quasi-Experimental Designs using Paired Samples T-tests. The results of the T-tests were compared before and after the training. The results showed a significant improvement in physical outcomes measurement tests; Berg Balance Scale (P = 0.000), 30-second Chair Stand (P = 0.001) and 4-meter Gait Speed (P = 0.000) among the elderly.

Abstract:

Osteoarthritis is a disease found in the elderly or often called a degenerative disease. The prevalence of total osteoarthritis in Indonesia was 34.3 million in 2002 and reached 36.5 million in 2007. An estimated 40% of the population above 70 years old suffer from osteoarthritis, and 80% of osteoarthritis patients have limited mobility in various degrees from mild to severe resulting in reducing the quality of life because of the high prevalence. The development of a simple approach to quantitatively estimating functional motor performance in various ages is very important for early detection of locomotive syndrome (LS), one of which is the sit to stand test (STST). In Indonesia, there are no studies that discuss STST, so the cut off point or even the average can be different. This can be influenced by differences in culture, demographics, activities, or treatment regimens. Based on the problem above, the researcher tries to find out the average and standard deviation of STST scores in Osteoathritis patients at Ahmad Yani Hospital, Surabaya by accidental sampling method on secondary data, namely Medical Records in 2019 at the Rehab ilitation outpatient clinic of Ahmad Yani Hospital in August-September 2019. The data recorded is in the form of quantitative data in units of seconds. Furthermore, the data is processed using SPSS 17 and displays the average value and standard deviation.

Abstract:

Background.In older patients, hospitalization is associated with a decline in functional performance and loss of muscle strength. Loss of muscle strength and functional performance can be prevented by systematic strength training, but details are lacking regarding the optimal exercise program and dose for older patients. Therefore, our aim was to test the feasibility of a progression model for loaded sit-to-stand training among older hospitalized patients.Methods.This is a prospective cohort study conducted as a feasibility study prior to a full-scale trial. We included twenty-four older patients (≥65 yrs) acutely admitted from their own home to the medical services of the hospital. We developed an 8-level progression model for loaded sit-to-stands, which we named STAND. We used STAND as a model to describe how to perform the sit-to-stand exercise as a strength training exercise aimed at reaching a relative load of 8–12 repetitions maximum (RM) for 8–12 repetitions. Weight could be added by the use of a weight vest when needed. The ability of the patients to reach the intended relative load (8–12 RM), while performing sit-to-stands following the STAND model, was tested once during hospitalization and once following discharge in their own homes. A structured interview including assessment of possible modifiers (cognitive status by the Short Orientation Memory test and mobility by the De Morton Mobility Index) was administered both on admission to the hospital and in the home setting. The STAND model was considered feasible if: (1) 75% of the assessed patients could perform the exercise at a given level of the model reaching 8–12 repetitions at a relative load of 8–12 RM for one set of exercise in the hospital and two sets of exercise at home; (2) no ceiling or floor effect was seen; (3) no indication of adverse events were observed. The outcomes assessed were: level of STAND attained, the number of sets performed, perceived exertion (the Borg scale), and pain (the Verbal Ranking Scale).Results.Twenty-four patients consented to participate. Twenty-three of the patients were tested in the hospital and 19 patients were also tested in their home. All three criteria for feasibility were met: (1) in the hospital, 83% could perform the exercise at a given level of STAND, reaching 8–12 repetitions at 8–12 RM for one set, and 79% could do so for two sets in the home setting; (2) for all assessed patients, a possibility of progression or regression was possible—no ceiling or floor effect was observed; (3) no indication of adverse events (pain) was observed. Also, those that scored higher on the De Morton Mobility Index performed the exercise at higher levels of STAND, whereas performance was independent of cognitive status.Conclusions.We found a simple progression model for loaded sit-to-stands (STAND) feasible in acutely admitted older medical patients (≥65 yrs), based on our pre-specified criteria for feasibility.

Abstract:

Purpose Prolonged workplace sitting can harm employee health. Sit-stand desks are a potential workplace health initiative that might reduce and break up the time office-based employees spend sitting in the workplace. However, little is known about the feasibility and acceptability of providing sit-stand desks. The paper aims to discuss this issue. Design/methodology/approach The present study sought stakeholder employee views surrounding sit-stand desk implementation within two UK-based non-profit organisations with open-plan offices. This paper draws on qualitative semi-structured interviews with 26 stakeholder employees and 65 days of participant observations. Data were analysed using thematic analysis, and organisational cultural theory framed the study. Findings Stakeholders employees’ positioning of sit-stand desks as a workplace health initiative reflected their perceptions of the relationship between sit-stand desk provision, employee health and organisational effectiveness. Perceptions were shaped by the nature and context of the organisation and by occupation-specific processes. Relatively fixed (e.g. organisational structure) and modifiable (e.g. selecting products compatible with the environment) factors were found to restrict and facilitate the perceived feasibility of implementing sit-stand desks. Practical implications The findings offer several recommendations for workplaces to improve stakeholder employee attitudes towards sit-stand desk provision and to increase the ease and efficiency of implementation. Originality/value Whilst extant literature has tended to examine hypothetical views related to sit-stand desk provision, this study consulted relevant stakeholders following, and regarding, the sit-stand desk implementation process.

Abstract:

Introduction Evaluation of sit-to-stand and stand-to-sit activities is used by physical therapists in patients with neurological and musculoskeletal disorders. Sit-to-stand activity presents different descriptions of phases and movements; however the phases of stand-to-sit activity have not been established yet.Objectives To describe the movements during stand-to-sit activity and create an evaluation protocol.Materials and methods Stand-to-sit activity was described on anterior and lateral views based on the observation of 27 healthy subjects. The body segments chosen to analyze were feet, ankles, knees, hips, pelvis, trunk, spine, upper limbs, head and cervical spine. The movements of body segments were described as adduction and abduction, eversion and inversion, valgus and varus, neutral position and asymmetry. The protocol was assessed with questionnaires answered by 12 physiotherapists experts in the area.Results Stand-to-sit activity was divided in 4 phases: 1- "Neutral position", 2- "Pre-squat", 3- "Squat" and 4- "Stabilization". Two models of protocols were developed considering 5 body segments to the anterior view and 7 segments for the lateral view.Conclusion Stand-to-sit activity was described in 4 phases with sequential movements of each body segment. These protocols allow physiotherapists to identify unusual movements of body segments during the stand-to-sit activity.

Abstract:

INTRODUCTION: Sit-to-stand and stand-to-sit are two of the most mechanically demanding activities undertaken in daily life and which are usually impaired in stroke subjects. OBJECTIVES: To determine the distinguishing characteristics in musculoskeletal biomechanical outcomes of the sit-to-stand and stand-to-sit activities with stroke subjects, with an emphasis on the clinical management of stroke disabilities, in a systematic review. MATERIAL AND METHODS: An extensive literature search was performed with the MEDLINE, CINAHL, EMBASE, PEDro, LILACS, and SciELO databases, followed by a manual search, to select studies on musculoskeletal biomechanical outcomes in both activities with stroke subjects, without language restrictions, and published until December/2007. RESULTS: Out of the 432 studies, only 11 reported biomechanical outcomes of both activities and none reached the total score on the selected quality parameters. The majority of the experimental studies which compared groups did not achieve acceptable scores on their methodological quality (PEDRo). The investigated conditions and interventions were also restricted. Only one study compared biomechanical outcomes between the activities, but only evaluated the time spent to perform them. Few musculoskeletal biomechanical outcomes have been investigated, being weight bearing on the lower limbs and duration of the activities the most investigated. CONCLUSION: There is little information regarding musculoskeletal biomechanical outcomes during these activities with stroke subjects and no definite conclusions can be drawn regarding the particularities of these outcomes on their performance with stroke survivors.

Abstract:

Background/Aims The sit-to-stand test is a quick and cost-effective measure of exercise tolerance and lower body strength. The literature focuses on its use in stable patients with chronic obstructive pulmonary disease. This study in patients hospitalised for chronic obstructive pulmonary disease exacerbation aimed to investigate possible associations of the sit-to-stand test with pulmonary function and risk of future acute exacerbations. Methods This study was conducted on a sample of 22 patients with chronic obstructive pulmonary disease. Participants' clinical details were recorded before they undertook spirometry, 30-second and five-repetition sit-to-stand tests. Participants were assessed via a structured telephone interview for the occurrence of acute exacerbation events in the 12 months following discharge. Results Patients were classified based on the presence or absence of acute exacerbations of chronic obstructive pulmonary disease over 12 months. A negative correlation was observed between five-repetition sit-to-stand test performance time and number of repetitions during the 30-second sit-to-stand test; longer sit-to-stand times and fewer repetitions were observed in patients who experienced exacerbations during follow up. The 30-second sit-to-stand test repetitions correlated positively with forced expiratory volume in 1 second (FEV1). Five-repetition sit-to-stand test performance correlated negatively with FEV1, FEV1% predicted, forced vital capacity and FEV1/forced vital capacity ratio. From the various exercise parameters, five-repetition sit-to-stand test performance time demonstrated a moderate ability to predict exacerbations. Conclusions This study is the first to focus on the use of the sit-to-stand tests in inpatients with acute exacerbation of chronic obstructive pulmonary disease. There was a significant correlation between the 30-second sit-to-stand test and five-repetition sit-to-stand test results. Both tests were associated with pulmonary function indices and risk of future chronic obstructive pulmonary disease exacerbations.

Abstract:

Background:Sit-to-stand movement is an essential function for participation in many activities of daily living. Although this movement is one of the most important functional tasks, there is limited research investigating strategies of sit-to-stand movement in transtibial amputees.Objectives:To examine movement strategies of the sit-to-stand task in persons with transtibial amputation and healthy non-amputated individuals.Study design:Cross-sectional study.Methods:A total of 12 male unilateral transtibial amputees and 19 healthy male subjects participated in this study. Sit-to-stand movement was evaluated in terms of weight transfer time, weight-bearing symmetry, sway velocity, and rising index by using Balance Master System.Results:Participants in both groups exhibited similar weight-bearing transfer time ( p > 0.05). Transtibial amputees demonstrated significantly greater weight-bearing asymmetry, higher sway velocity, and lower rising index than healthy subjects during the sit-to-stand transfer movement ( p < 0.05).Conclusions:Transtibial amputees were unable to use the same movement strategies during a sit-to-stand task as healthy individuals; therefore, they had to develop new strategies to perform this task.Clinical relevanceLittle is known about the altered movement strategies during sit-to-stand task in transtibial amputees. The results of the study might provide some new insight into the motor components of the sit-to-stand movement in persons with transtibial amputation for both clinicians and researchers.

Abstract:

This study describes the approach taken and the results measured thus far from the introduction of sit-stand workstations in an office environment. Adjustable workstations have been developed and introduced in an office within United Parcel Service (UPS). A sit-stand workstation consists of the following components: modular panel walls, an adjustable front work surface, an adjustable rear work surface, and an adjustable chair. An employee can sit or stand while working and perform the adjustments to the workstation with fingertip ease and control. The job requirements of all of the employees using the new workstations are sedentary in which there is constant use of the computer to perform a variety of tasks. A training program was also introduced to review basic principles of human factors and ergonomics and to provide instruction in how to properly use the new workstations, chairs, and other accessories. Prior to the installation of the workstations, various benchmark data were collected including: production levels, absenteeism, and injuries and illnesses. A survey of body part discomfort identified areas that were of concern. Following the installation of the workstations, the same data have been and will continue to be collected to measure the effectiveness of the ergonomic interventions. Body part discomfort decreased by an average of 62 percent. Production in two departments that were monitored demonstrated improvement, however at this time the study cycle is too short to hypothesize long term results. The occurrence of injuries and illnesses decreased by more than half. Absenteeism did not show significant changes. These data will continue to be tracked to measure the results of the interventions.
