OBJECTIVE:There is no consensus on which sit-up strategy to adopt in knee osteoarthritis patients of different ages.Therefore,this study evaluated the biomechanical characteristics of sit-ups in knee osteoarthritis patients of different ages compared with healthy individuals by meta-analysis system and analyzed the sit-up movement patterns of patients of different ages to provide a reference for improving the sit-up function of patients. METHODS:By March 2023,observational studies of biomechanical characteristics of sitting up in patients with knee osteoarthritis and healthy population were retrieved on PubMed,Web of Science and CNKI.Subjects were required to be patients over 50 years of age with knee osteoarthritis who had Kellgren-Lawrence severity grading≥Ⅰ on knee imaging and who had regular knee pain.Subjects were analyzed by age(50-60 years vs.over 60 years)and severity(mild to moderate patients vs.severe patients)subgroups according to inclusion and exclusion criteria.Quality assessment was performed using the modified Down and black scale.Stata 16.0 software was used to perform subgroup analysis to determine the biomechanical characteristics of sitting up in patients with knee osteoarthritis of different ages and severities. RESULTS:A total of 14 randomized controlled trials(824 subjects)were included in the meta-analysis.The mean quality score of all included literature was 76.2,with a range of 66.7 to 86.7,all of which were of medium to high quality and representative.The included studies were of moderate to high quality and representative.Meta-analysis results found that(1)compared to healthy individuals,patients with knee osteoarthritis had longer total sitting up time(SMD=0.92,95%CI:0.76-1.09),P<0.001)and longer extension phase time(SMD=0.46,95%CI:0.18-0.74,P=0.001).Compared to mild to moderate patients,the total duration increased more significantly in severe patients(P<0.001)and the duration of the extension phase increased more significantly in patients over 60 years of age than in patients 50-60 years of age(P=0.001).(2)Compared to healthy individuals,patients with knee osteoarthritis had greater sitting-up trunk flexion motion range(SMD=0.64,95%CI:0.37-0.91,P<0.001);knee flexion motion range(SMD=-0.47,95%CI:-0.70 to-0.24,P<0.001)and ankle dorsiflexion motion range(SMD=-0.32,95%CI:-0.56 to-0.08,P=0.01)were smaller.And knee flexion motion range decreased more significantly in patients over 60 years of age than in patients 50-60 years of age(P<0.001).(3)The peak hip flexion moment(SMD=-0.57,95%CI:-0.83 to-0.31,P<0.001)and peak knee extension moment(SMD=-0.83,95%CI:-1.08 to-0.59,P<0.001)were smaller in patients with knee osteoarthritis. CONCLUSION:(1)Patients with knee osteoarthritis over the age of 60 years have a longer sit-up cushion and extension phase than patients aged 50 to 60 years.The increase in total sit-up duration was also more pronounced in patients with higher severity grades.The increased length of sitting up in patients with advanced age and knee osteoarthritis severity may increase the duration of cartilage loading,exacerbate knee pain symptoms,and increase the difficulty of sitting up in this population.(2)Patients with knee osteoarthritis exhibit limited knee and ankle flexion motion range.Knee mobility is more limited in patients over 60 years of age.(3)Patients with knee osteoarthritis have reduced peak hip flexion and knee extension moments,which may be a compensatory strategy for pain relief.

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.

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.

| 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.

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.

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.

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.

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.

<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>

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.
Résumé
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 complet-ed STS movement with 3 different foot positions:ankle dorsiflexed 10° of both feet (BF), with the paretic foot posterior (PFP) or the undom-inant 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-lat-eral (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.
