INTRODUCTION: To find the reference values for the 30-second sit-to-stand test and study the correlation of anthropometric measures with the test in the communitydwelling geriatric Indian population. MATERIAL AND METHODS: 136 individuals aged >60 years were recruited in this cross-sectional observational study. The study was conducted in India. After the initial screening, anthropometric measurements were recorded. Then, the 30-second sit-tostand test was conducted. RESULTS: Normal decade-wise values for the test were reported to be (mean ± SD): 60-70 years (10.2±3.6), 71-80 years (9.5±3.4), and 81-90 years (8.5±5.2). Age, height, waist circumference, and hip circumference were significantly associated with the 30-second sit-to-stand test values. CONCLUSION: Normal values for the test in the community-dwelling geriatric population were reported to be mean ± SD 10.0±3.7. Anthropometric factors should be taken into consideration when performing the 30-second sitto-stand test in clinical settings.

Objective By establishing finite element model of the proximal femur, the injury risk of proximal femur under the conditions of self-selected speed rise and rapid rise at initial stage of standing during sit-to-stand (STS) transition was analyzed.Methods CT images of proximal femur in the elderly were processed with three-dimensional (3D) reconstruction and reverse modeling, so as to complete the solid model. The finite element model was established through material assignment and meshing. Based on the finite element analysis software ANSYS, the boundary conditions were constrained, and 1.733 kN and 1.837 kN loads were applied to obtain stress distributions and strain of proximal femur at different rising speeds. Results The stress concentrated at medial edge of the greater trochanter and the femoral neck. The peak stress and micro-strain appeared on inner edge of the larger rotor. The peak stress was 30.16 MPa and peak micro-strain was 2 553.5 at rapid rising speed. The peak stress and peak micro-strain at self-selected rising speed were 28.69 MPa and 2 430.4, respectively, which were relatively lower. For stress concentration area of femoral neck, the stress ranges at rapid rising speed and self-selected rising speed were 13.42-23.46 MPa and 12.76-25.51 MPa, respectively.Conclusions Frequent STS transition may increase the risk of fatigue fractures for proximal femur in the elderly. Rapid STS transition has a higher injury risk for proximal femur than STS transition at self-selected speed.
ABSTRACT
Objects：Sit-to-stand (STS) interventions are frequently used as part of stroke rehabilitation. This study aimed to clarify the kinematic and kinetic characteristics of patients recovering from stroke, who have difficulties with STS movement.Method：The participants included 26 stroke patients who struggled to complete the STS maneuver. Using a 3D motion analysis system, the kinematic and kinetic parameters during STS were retrospectively analyzed and compared between failed and successful trials. The kinematic parameters of the trunk and lower limbs were obtained within the seat-off phases, and the kinetic indices of the lower limbs were obtained from measurements taken before and after the seat-off phase. The weight-bearing ratio on the unaffected side was calculated from the vertical ground reaction forces.Results：In the successful trials, analyses of the parameters revealed more forward tilting of the pelvic and thoracic regions, a further forward and downward shift of the center of mass, and larger hip and knee extension moments than those of the failed trials. However, there was no difference in the weight-bearing ratio on the non-paralyzed side.Conclusion：This study revealed that the kinematic and kinetic properties of the STS maneuver differed between successful and failed trials among patients with stroke. The study therefore provides useful information for clinical evaluation and rehabilitation.

ABSTRACT
| INTRODUÇÃO: As repercussões cardiorrespiratórias da cirurgia cardíaca podem ser avaliadas por teste submáximo. OBJETIVO: comparar as respostas cardiorrespiratórias do teste de sentar e levantar em um minuto (TSL1) nos indivíduos, entre o momento pré e pós de cirurgia cardíaca. MÉTODOS: Estudo de caráter transversal e analítico, incluiu 45 indivíduos de ambos os sexos, estáveis hemodinamicamente, com fração de ejeção maior que 45%, que foram submetidos à cirurgia de revascularização do miocárdio no Instituto do Coração de um Hospital do interior do estado do Rio Grande do Sul, entre 2018 e 2019. As variáveis de desfechos foram coletadas no repouso e ao final do teste, um dia antes da cirurgia e no pós-operatório: pressão arterial sistólica e diastólica (PAS e PAD em mmHg), frequência cardíaca (FC bpm), frequência respiratória (FR rpm), saturação periférica de oxigênio (SpO2 %), fadiga de membros inferiores (Fmm 0-10) e dispneia (Di 0-10), número de repetições e interrupções do teste. Foi utilizado o programa R para o tratamento dos dados, para avaliar a normalidade foi aplicado o teste de Shapiro Wilk, a comparação dos grupos pelo teste não paramétrico de Wilcoxon. RESULTADOS: A maioria do sexo masculino (71%) e média de idade foi de 61± 9 anos. No pré-operatório, ocorreu aumento entre o repouso e o final do teste, PAS, FC, FR, Fmm e Di (p<0,05). No pós-operatório, houve aumento entre o repouso e o final do teste, para FC, FR, Fmm e Di (P<0,05), contudo, sem elevação da PAS. Ao comparar as variáveis entre os momentos pré e pós, observamos maiores valores da FC, FR e número de interrupções na condição pós (p<0,05), bem como menores valores para a PAS, SpO2 e número de repetições (p<0,05) para essa condição. CONCLUSÃO: Os dados desta pesquisa comprovam que o TSL1 realizado no pré-operatório de cirurgia cardíaca, assim como entre o 4° ou 5° dia de pós-cirurgia cardíaca, é seguro e eficaz, representado pela ausência das repercussões cardiorrespiratórias que comprometessem ou agravassem o quadro clínico do paciente. O TSL1 foi capaz de induzir respostas cardiorrespiratórias fisiológicas no pré-operatório; contudo, na condição pós acarretou respostas cardiorrespiratórias mais elevadas no repouso e atenuada resposta em exercício em comparação ao pré-operatório.
INTRODUCTION: The cardiorespiratory repercussions of heart surgery can be assessed through submaximal testing. OBJECTIVE: Compare cardiorespiratory responses to the one-minute sit-and-stand test in individuals pre- and post-heart surgery. METHODS: An analytical, cross-sectional study was conducted involving 45 hemodynamically stable male and female patients with an ejection fraction greater than 45% submitted to coronary artery bypass surgery at a cardiology service of a hospital in the interior of the state of REDACTED between 2018 and 2019. The following variables were collected at rest and the end of the test one day before surgery and postoperatively: systolic and diastolic blood pressure (SBP and DBP, mmHg), heart rate (HR, bpm), respiratory rate (RR, rpm), peripheral saturation oxygen (SpO2, %), lower limb fatigue (LLF, 0-10), dyspnea (0-10), number of test repetitions and number of interruptions. The R program was used to process the data. The Shapiro-Wilk test was used for the determination of normality. The groups were compared using the non-parametric Wilcoxon test. RESULTS: Most participants were male (71%), and the mean age was 61±9 years. In the preoperative period, statistically significant increases (p≤0.05) were found for SBP, HR, RR, LLF, and dyspnea between resting values and the end of the test. Significant increases (p≤0.05) were found in the postoperative period for HR, RR, LLF, and dyspnea between rest and the end of the test, with no increase in SBP. Comparing the preoperative and postoperative evaluations variables, higher HR, RR, the number of interruptions and lower SBP, SpO2, and the number of repetitions were found after surgery (p≤0.05). CONCLUSION: The one-minute sit-to-stand test induced physiological cardiorespiratory responses in the preoperative evaluation. However, higher cardiorespiratory responses at rest and an attenuated response to exercise were found in the postoperative evaluation compared to the preoperative evaluation.

ABSTRACT
Objective:To study the human body's sit to stand transfer trajectory and kinematics based on knee joint support to provide a basis for designing the transfer aid with knee joint support. Methods:From April to June, 2019, 20 healthy volunteers were recruited and divided into three groups according to height and gender. Under the premise of knee support, the sit to stand transfer experiments with 20 cm and 30 cm between feet were conducted respectively. All subjects were repeated twice for each experiment with an interval of one minute. High-definition camera was used to record the motion trajectories of each subject's shoulder (armpit) and knee joint during the experiment, and the kinematics rules of subjects with different heights and masses were analyzed. Results:The body forward leaning displacement was less with 20 cm between feet than with 30 cm for subjects less than 172 cm tall; and was less with 30 cm than with 20 cm for subjects more than 173 cm tall. The forward flexion displacement of trunk was less with 20 cm between feet than with 30 cm for subjects with body mass index (BMI) < 23.9 kg/m2; and was less with 30 cm than with 20 cm for subjects with BMI > 23.9 kg/m2. The average time during sit to stand transfer was (1.7±0.05) s. Conclusion:In the process of sit to stand transfer, distance between feet may affect the way of joint extension, the body forward leaning distance and the forward flexion displacement of trunk. With the increase of height and mass, appropriate increase of distance between feet can reduce the difficulty of sit to stand transfer. With the increase of BMI, the time of sit to stand transfer also increases. The time spent on sit to stand transfer is more in female than in male.
ABSTRACT
Objective:To study the effect of chair inclination angles forward on sit-to-stand time and muscle activation of lower extremities in stroke patients with hemiplegia. Methods:From January to August, 2019, 15 stroke patients with hemiplegia finished five times sit-to-stand at seat slope 0°, 10° and 20° forward. The time, and surface electromyogram (sEMG) signals of rectus femoris, hamstrings, anterior tibialis and peroneus muscle were recorded. Results:The total EMG peak, root mean square and integrated electromyography (iEMG) of all the muscles decreased at seat slope 10° and 20° forward compared with those at 0° (F > 4.530, P < 0.05). The time decreased at seat slope 20° forward compared with that at 0° (P < 0.05). Conclusion:Seat inclination forward at some angles may improve the sit-to-stand performance in stroke patients with hemiplegia.
ABSTRACT
Introduction: Functional status assessment in patients suffering with Chronic Obstructive Pulmonary Disease (COPD) is the essential component and Six-Minute Walk Test (6MWT) is a valid tool for it. The amount of physical activity possible in patients with chronic obstructive pulmonary disease (COPD) predicts exacerbations, hospital admissions, and mortality. Therefore, guidelines advocate the need to entitle improved physical activity status as a major target of treatment in such patients. Objective: To determine the correlation of sit to stand test with 6-minute walk test in patients with chronic obstructive pulmonary disease. Methodology: An analytical cross-sectional study was done in Chest Medicine department, Jinnah hospital, Karachi during 2015-16. A total of 100 patients with mildto-severe COPD were included in this study. The STST and 6MW Test was performed and compared with each other and with COPD Assessment Test (CAT). Results: Overall 100 patients were recruited for the study with mild-tosevere chronic obstructive pulmonary disease. The mean age of the patients was 60.50 ± 7.03 years. On applying the Correlation coefficient test, a moderate positive correlation was found between Sit to stand test and 6-minute walk test distance (r=0.71, p=0.0005). Mild positive correlation was also found in these patients between the Sit to stand test and chronic obstructive pulmonary disease Assessment Test score (STST and CAT r=0.46, p=0.011). Similarly, moderate positive correlation was found between 6-minute walk test distance and chronic obstructive pulmonary disease Assessment Test score (r=0.58, p=0.001). Conclusion: It is concluded that in COPD patients, the functional capacity can be assessed through STST instead of 6 MW Test having the same results.

ABSTRACT
@#Hemiplegics after stroke are often disabled in sit-to-stand(STS).This article discussed the biomechanics of STS in the hemiplegic stroke patients,in terms of kinematics,kinetics and surface electromyography,and the rehabilitation for the stroke patients with STS dysfunction.It was found that the stability,duration,symmetry of support and degree and se-quence of muscular activation were different when the patients finished the STS task in three foot positions of natural, symmetrical and unaffected foot behind.The early STS rehabilitation training or other rehabilitation may improve the function of the hemiplegic lower extremity to prevent falls and apraxia.
ABSTRACT
Objective To evaluate the physical functions of community-dwelling older adults, and analyze the related factors. Methods From September to October, 2016, 80 adults over 55-year-old in one community in Wuhan, Hubei, China were selected with convenience sampling. General situation was collected through questionnaires. Physical functions were measured by tests of grip strength, Five-Times-Sit-to-Stand Test (FTSST), modified Clinical Test of Sensory Interaction and Balance (mCTSIB) and TimedUp and GoTest (TUGT). Their correlation was analyzed. Results The average grip strength of the participants was (27.46 ± 9.66) kg; the average time of FTSST was (11.58 ± 4.03) s;there was only one (1.25%) participant observed with an impairment in mCTSIB;the average time of TUGT was (9.05±3.47) s. Grip strength was correlated with gender (r=-0.669), education level (r=0.238), the score of Mini-Mental State Examina-tion (MMSE) (r=-0.302) and activities of daily living (ADL) (r=-0.344) (P<0.05). The time of FTSST was correlated to gender (r=0.274), the score of MMSE (r=0.243) and ADL (r=0.321) (P<0.05). The time of TUGT was correlated to gender (r=0.255), education level (r=-0.362), income level (r=-0.245), the score of Self-rating Depression Scale (r=0.223), the score of MMSE (r=0.328) and ADL (r=0.354) (P<0.05). Conclusion The levels of grip strength, FTSST and TUGT are related to the demographic characters in community-dwell-ing older adults. Little abnormity has been found in mCTSIB.
ABSTRACT
Objective Currently,the sit-to-stand process is not well evaluated.The aim of the study is to evaluate quantitatively the reliability of posturographic parameters in the sit-to-stand process.Methods Seventy-four healthy participants were enrolled and required to finish 20-second sitting,standing and the sit-to-stand process.The computer calculated the posturographic parameters automatically.The test was repeated twice to assess the reliability at an interval of six days.Results During sitting and standing position,the intraclass correlation coefficients (ICCs) of all the parameters were above 0.50,indicating a good or fair reliability.During the standing stance and sitting phase of the sit-to-stand process,the ICCs of all the parameters were above 0.40 and 0.60 respectively,showing a good or fair reliability.Conclusions Sit-to-stand posturographic parameters are a new way to assess the position control ability among the healthy participants with a good reliability.Further study should be conducted among patients to result in better functional and effectiveness evaluation.
ABSTRACT
<p>We aimed to elucidate the impact of the conducting state in exercise programs and the degree of improvement in sit-to-stand power index (STS-PI) on the continuation of Chokin exercise by participants one year from the completion of the intervention period. Subjects participated in a 12-week Chokin exercise class for the elderly, which consisted of 10 body mass-based exercises. As variables indicating exercise conditions, the number of exercise days weekly and the total number of sets performed during the intervention period were adopted. STS-PI was calculated using the time required to perform 10-times-repeated sit-to-stand task, and its relative change (%∆STS-PI) was used to represent the degree of improvement in physical function. Among 52 men and 129 women who responded to the inquiry about the continuation of Chokin exercise one year from the completion of the intervention period, 32 men and 93 women confirmed continuation of the exercise program. Logistic regression analysis showed that %∆STS-PI for men, as well as %∆STS-PI and the number of exercise days weekly for women, were factors associated with the decision of subjects to continue the Chokin exercise. These results indicate that the degree of improvement in STS-PI associated with the Chokin exercise class is a factor for continuing the exercise program one year from the completion of the intervention period, at least in elderly men and women. Furthermore, high exercise frequency during the intervention period may be associated with the decision to continue Chokin exercise after the completion of the intervention among women.</p>
ABSTRACT
Objective To determine the value of five repetition sit-to-stand test (FTSST) to evaluate lower limb function in the patients with chronic obstructive pulmonary disease (COPD).Methods Sixty-one patients with COPD were tested for FTSST,isokinetic testing muscle strength for lower limb,6-minute walking test.The relationship between FTSST time and muscle strength,6-minute walking test distance (6MWD) were analyzed.Results FTSST time was (7.86±2.21) s,extensor peak torque was (67.58± 24.83) Nm,extensor relative peak torque was 0.95(0.46) Nm/kg,6MWD was (444.05±112.53) m.FTSST time related to extensor peak torque,extensor relative peak torque,6MWD and types of complication,correlation coefficient values were-0.303,-0.393,-0.428,F =2.813,P ＜ 0.05.Multivariate linear regression analysis showed that when the dependent variable was FTSST time,the variables of the equation were 6MWD and types of complication.Conclusions FTSST can be used for the rapid evaluation of lower extremity function in patients with COPD.The lower limb function gets worse,the FTSST time will be longer.Nursing staff should pay more attention to the lower limb function of patients with COPD,along with complications,using FTSST to evaluate lower extremity function.
ABSTRACT
OBJECTIVE: The purpose of this study was to compare postural control in typically developing (TD) children and children with cerebral palsy (CP) during the sit-to-stand (STS) movement and to assess the relationship between static (during static standing position) and dynamic postural control (during STS movement) in both groups. METHOD: The center of pressure (CoP) behavior of 23 TD children and 6 children with spastic hemiplegic CP (Gross Motor Function Classification System [GMFCS] I and II) was assessed during STS movement performance and during static standing conditions with the use of a force plate. The data obtained from the force plate were used to calculate CoP variables: anteroposterior (AP) and mediolateral (ML) amplitudes of CoP displacement and the area and velocity of CoP oscillation. RESULTS: According to the Mann-Whitney test, children with CP exhibited higher CoP values in all of the analyzed variables during the beginning of STS movement. Pearson's correlation verified a positive correlation between the CoP variables during both static conditions and the performance of STS movement. CONCLUSIONS: Children with spastic hemiplegic CP present major postural oscillations during the beginning of STS movement compared with typical children. Moreover, the observed relationship between postural control in static and dynamic conditions reveals the importance of body control in the static position for the performance of functional activities that put the body in motion, such as STS movement. .

@#Objective To explore the interaction of foot placement, trunk control and weight-bearing (WB) during sit-to-stand (STS) movement. Methods 32 hemiplegic stroke patients (experimental group) and 32 healthy people (control group) were recruited and completed STS movement with 3 different foot positions: ankle dorsiflexed 10° of both feet (BF), with the paretic foot posterior (PFP) or the undominant foot posterior (UDFP), with the non-paretic foot posterior (NPFP) or the dominant foot posterior (DFP). Balance function assessment system (model AL-080) was used for collecting the WB, WB asymmetry (WBasym), and the center of pressure of the buttocks in medial-lateral (CoPx) and anterior-posterior (CoPy) sway during STS movement. Results The control group had the mostly WB symmetry, and little trunk side movement in BF, and there was significant difference in all indicators compared with in DFP or UDFP. For the experiment group, the WB, WBasym and CoPx were different as BF from as NPFP (P<0.05); while all the indicators except CoPx were different from PFP. When PFP, the trunk moved to the non-paretic side, and then to paretic side, all the indicators were different from NPFP. When BF and NPFP of the experiment group compared with BF and DFP of the control group, all the indicators were different (P<0.05). CoPx and CoPy increased in the experiment group compared with the control group. CoPx negatively correlate with WBasym in the experiment group (r=-0.626, P<0.001) and in the control group (r=-0.776, P<0.001). Conclusion The trunk side movement affects weight-bearing symmetry, and foot placement can modify weight-bearing distribution during the STS movement in hemiplegic stroke patients.

ABSTRACT
Levantarse de una silla y volver a sentarse es una de las actividades que se realizan varias veces al día siendo un requisito importante para el logro de muchos objetivos funcionales como lo es caminar. La incapacidad para realizar la transferencia de sedente a bípedo (SAB) conduce a una limitación severa en la movilidad, como en el caso de las personas con parálisis cerebral (PC). El objetivo de este artículo fue describir las características biomecánicas y sistemas de análisis de la transferencia de SAB en niños con PC, por medio de la revisión de artículos en diferentes bases de datos. El análisis parte de 50 artículos y culmina en la selección de 11. Los resultados eviden-cian un incremento en el tiempo de ejecución de la tarea, con clara evidencia de movimientos compensatorios en los niños con PC para poder ejecutar y finalizar el paso de SAB, además de una relación entre el nivel de GMFCS y la capacidad de hacer la transferencia. Se concluye acerca de la importancia en la evaluación de este tipo de trasferencia para poder determinar el grado de independencia funcional de los niños con PC, además de tener en consideración factores que son determinantes a la hora de realizar el cambio de SAB, como lo es la posición del tobillo y la altura de la silla para realizar con eficacia el movimiento, lo que traduce un aumento del desempeño funcional del niño con PC en su entorno cotidiano.
Getting-up and sitting from a chair is a frequent activity during the day, and is an important requirement for achieving functional goals such as walking. Inability to sit-to-stand (STS) leads to severe mobility limitations like in Cerebral Palsy (CP) patients. The aim of this study is to describe biomechanical characteristics and analysis systems of the change from STS in children with CP by means of reviewing published papers in scientific databases. Fifty papers were fond and 11 were selected. An increase in the task execution time of the change from SSP was found in children with CP, along with compensatory movements necessary to achieve the task. Besides, a relationship between the GMFCS level and task execution time was also found. Assessing this kind of tasks are important for define functional independence in children with CP. Besides, it is important to consider compensatory movements when performing change from STS, like ankle position, and other variables like the height of the chair, when children perform the activity. Controlling these variables reflects a better functional performance of children with CP in their every-day environment.

The purpose of this study was to investigate the physiological and psychological effects of sit to stand exercise using a video game. Twelve young male adults performed sit to stand exercise with a video game and without a video game. Heart rate, oxygen consumption (VO<sub>2</sub>), electromyogram of lower limbs (%MVC) and perceived exertion (RPE) were measured during exercise. Mood states (POMS) were measured before and after exercise. There were no significant differences in physiological measurements between the two conditions. On the other hand, depression scale was significantly decreased after exercise only in the game condition. These results suggest that sit to stand exercise with a video game may have positive psychological effects without change in physiological load compared to the same exercise without a video game.
