Determination of Body Composition in Community-Dwelling Older Adults With and Without Sarcopenia Using Data From Practical Measures.

Adequate body composition is essential for health, function, and independence in older adults. However, standard body composition assessments require complex and costly modalities, limiting their use for early detection of body composition changes and periodic follow-up. This study explored the ability of three practical measures-handgrip strength, five times sit-to-stand test, and upper limb loading during seated push-up test (ULL-SPUT)-to determine body composition in 109 older adults with and without sarcopenia. Participants (average age 76 years) were cross-sectionally measured for outcomes of the study. The ULL-SPUT and handgrip strength, but not the five times sit-to-stand test, significantly correlated with body composition (rs, r = .297-.827, p < .01). The ULL-SPUT, in combination with demographic data, could determine body composition up to 82%. Therefore, the ULL-SPUT may be a practical preliminary measure to identify older adults for whom standard body composition assessments and follow-up would prove timely and beneficial.

The determination of sarcopenia in older adults using a practical measure.

BACKGROUND: Many older adults are at risk of sarcopenia, a gradual loss of muscle mass affecting muscle strength and physical function, which can lead to adverse health consequences deteriorating their independence. However, the detection could be delayed due to the requirement of many measures, including a complex imaging modality. Thus, an exploration for a practical community- or home-based measure would be helpful to identify at-risk older adults and begin the timely management. OBJECTIVE: To explore the ability of the upper limb loading during a seated push-up test (ULL-SPUT) to determine the presence of sarcopenia in community-dwelling older adults. METHODS: Older adults (n= 110; 62 females, average age approximately 77 years) were cross-sectionally assessed for sarcopenia using standard measures (handgrip strength, appendicular skeletal muscle mass, and walking speed) and the ULL-SPUT. RESULTS: Data from standard measures indicated that 44 participants had sarcopenia. The ULL-SPUT index of < 16.9 kg/m2 for females (sensitivity = 86%, specificity = 78%, area under the receiver operating characteristic curve [AUC] = 0.85) and < 19.7 kg/m2 for males (sensitivity = 73%, specificity = 69%, AUC = 0.83) could optimally identify participants with sarcopenia. CONCLUSION: The ULL-SPUT index could be used to screen and monitor older adults with sarcopenia in various clinical, community, and home settings. This practical measure may be accomplished using a digital bathroom scale on a hard, even surface. Outcomes would identify an adult who should undergo further confirmation of sarcopenia through standard measures or the initiation of timely management to promote treatment effectiveness.

The Use of Practical Measures to Determine Body Composition of Older People.

Background: Older adults frequently experience body composition changes-decreased lean body mass (LBM) and bone mineral content (BMC), along with increased body fat mass (FM)-which affect their health and independence. However, the need for standard complex and costly imaging modalities could delay the detection of these changes and retard treatment effectiveness. Thus, this study explored the ability of practical measures, including simple muscle strength tests and demographic data, to determine the body composition of older adults. Methods: Participants (n = 111, with an average age of 77 years old) were cross-sectionally assessed for the outcomes of the study, including upper limb loading during a seated push-up test (ULL-SPUT), hand grip (HG) strength test and body composition. Results: The ULL-SPUT significantly correlated with body composition (r or rs, = 0.370-0.781; P < 0.05), particularly for female participants and was higher than that found for the HG strength test (rs = 0.340-0.614; P < 0.05). The ULL-SPUT and HG strength test, along with gender and body mass index (BMI), could accurately determine the LBM and BMC of the participants up to 82%. Conclusion: The ULL-SPUT along with gender and BMI can be used as a practical strategy to detect the LBM and BMC of older adults in various settings. Such a strategy would facilitate timely managements (i.e. standard confirmation or appropriate interventions) in various settings.

The seventh cervical vertebra is an appropriate landmark for thoracic kyphosis measures using distance from the wall.

Background: Hyperkyphosis is frequently found nowadays due to the change in current lifestyles and age-related system decline. A simple hyperkyphosis measurement can be made easily using the perpendicular distance from the landmark to the wall. However, the existing evidence applied two different landmarks [occiput and the seventh cervical vertebra (C7)] and the measurement using rulers was susceptible to error due to their misalignment. Objective: To assess an appropriate landmark for thoracic kyphosis measurement using distance from the wall (KMD), by comparing between occiput and C7, as measured using rulers and verified using data from a specially developed machine, the so-called infrared-gun kyphosis wall distance tool (IG-KypDisT), and the Cobb angles. Methods: Community-dwelling individuals with a risk of thoracic hyperkyphosis (age ≥10 years, n=43) were cross-sectionally assessed for their thoracic hyperkyphosis using the perpendicular distance from the landmarks, occiput and C7, to the wall using rulers and IG-KypDisT. Then the Cobb angles of these participants were measured within seven days. Results: The outcomes from both landmarks differed by approximately 0.8 cm (p= 0.084). The outcomes derived from C7 were more reliable (ICCs>0.93, p<0.001), with greater concurrent validity with the radiologic data (r= 0.738, p<0.001), with the overall variance predicted by the regression models for the Cobb angles being higher than that from the occiput (47-48% from C7 and 38-39% from occiput). The outcomes derived from rulers and IG-KypDisT showed no significant differences. Conclusion: The present findings support the reliability and validity of KMD assessments at C7 using rulers as a simple standard measure of thoracic hyperkyphosis that can be used in various clinical, community, and research settings.

Effects of modified long stick exercise on hyperkyphosis, muscle imbalance and balance control in elderly community-dwelling women with hyperkyphosis.

BACKGROUND: Hyperkyphosis is a condition often seen in older women. This condition causes muscle imbalance in the upper back of the body and impacts balance control. Long stick exercise (LSE) is an exercise programme for the elderly that improves muscle strength and balance control. OBJECTIVE: This research was designed to investigate the effects of a modified LSE on hyperkyphosis, muscle imbalance and balance control in elderly community-dwelling women with hyperkyphosis. METHODS: Twenty-eight elderly women with hyperkyphosis were divided into experimental and control groups. The experimental group was assigned to practice the modified LSE programme 30-40 minutes/day, 3 days/week, for 12 weeks. Hyperkyphosis, pectoralis minor length, muscle strength, functional reach test (FRT) and timed up and go test (TUG) were obtained at baseline, after 6 weeks and after 12 weeks of exercise. RESULTS: The experimental group demonstrated improved hyperkyphosis, pectoralis minor length, muscle strength, FRT, and TUG after 12 weeks of training. Moreover, the experimental group exhibited significantly greater improvements in all outcomes than the control group (p< 0.05). CONCLUSION: The modified LSE programme is an alternative exercise that is easy and low-impact for improving hyperkyphosis, muscle imbalance, and balance control in elderly community-dwelling women with hyperkyphosis.

Walking speed to determine walking performance of people with mobility limitations from a developing country.

BACKGROUND: The criteria to determine walking performance of people with mobility limitations from developed countries have been already reported. However, these criteria may not be suitable to be applied for people with mobility limitations from developing countries due to the differences in sociodemographic characteristics and environmental conditions. OBJECTIVE: To explore cutoff points of walking speed to determine walking performance of individuals with mobility limitations from a developing country. METHODS: Individuals with mobility limitations from a developing country (n = 136) were cross-sectionally interviewed and assessed for their demographics and walking performance. Then they were assessed for their walking speed using the 10-meter walk test. RESULTS: Walking speeds of ≥0.30 m/s, ≥ 0.40 m/s, and ≥0.65 m/s could optimally indicate the ability of outside-home walking, limited-community walking, and full-community walking, respectively (sensitivity = 78%-84%, specificity = 81%-93%, and area under the receiver operating characteristic curve [AUC] > 0.90). Moreover, a walking speed of ≥0.35 m/s could suggest the ability of functional walking (sensitivity = 78%; specificity = 83%; and AUC = 0.89). CONCLUSIONS: With the need of standard practical measure for early screening and monitoring of functional alteration over time, the present walking speed cutoff points may be clinically applied to suggest walking performance in daily living specifically for individuals with mobility limitations from a developing country.

The Use of a Single-Time Sit-To-Stand Test in Ambulatory Individuals With Spinal Cord Injury by Primary Health Care Providers.

Background: The uncertain health care situations, such as that created by the COVID-19 pandemic, has limited hospital access and facilitated a paradigm shift in health care toward an increased demand for standard home visits and community-based rehabilitation services, including by ambulatory individuals with spinal cord injury (SCI). Objectives: This 6-month prospective study explored the validity and reliability of a single-time sit-to-stand (STSTS) test when used by primary health care (PHC) providers, including a village health volunteer, caregiver, individual with SCI, and health professional. Methods: Eighty-two participants were assessed for the STSTS using four arm placement conditions (arms on a walking device, arms on knees, arms free by the sides, and arms crossed over the chest) and standard measures, with prospective fall data follow-up over 6 months. Thirty participants involved in the reliability study were also assessed and reassessed for the ability to complete the STSTS conditions by PHC providers. Results: Outcomes of the STSTS test, except the condition with arms on a walking device, could significantly discriminate lower extremity muscle strength (LEMS) and mobility of the participants (rpb = -0.58 to 0.69) with moderate concurrent validity. Outcomes of the tests without using the arms also showed moderate to almost-perfect reliability (kappa = 0.754-1.000) when assessed by PHC raters. Conclusion: The findings suggest the use of an STSTS with arms free by the sides as a standard practical measure by PHC providers to reflect LEMS and mobility of ambulatory individuals with SCI in various clinical, community, and home-based settings.

Ability of the Seventh Cervical Vertebra Wall Distance to Determine Mobility Deficits of Older Adults.

Thoracic hyperkyphosis could affect mobility and independence of older adults. However, there was no clear evidence on the use of the seventh cervical vertebra wall distance (C7WD), a practical measure for thoracic hyperkyphosis, to indicate mobility deficits relating to independence of these individuals. This study explored the ability of C7WD to determine mobility impairments in 104 older adults. Participants (average age of 74.1 ± 7.4 years) with various degree of thoracic kyphosis were cross-sectionally measured for their C7WD, mobility, and Cobb angle. The findings indicate that participants with thoracic hyperkyphosis (Cobb angle = 46.1 ± 5.2°) had significantly poorer mobility than those without thoracic hyperkyphosis (Cobb angle = 32.8 ± 5.9°, p < .05). A C7WD of ≥7.8 cm could indicate mobility deficits of the participants (sensitivity = 71%-92%, specificity = 75%-94%, and area under the curve >0.80). The findings confirm the ability of C7WD that could be clinically measured using rulers to indicate mobility deficits of older adults.

Seated push-up tests: Reliable and valid measures for older individuals when used by primary healthcare providers.

BACKGROUND: Body composition decline, lower limb impairments, and mobility deficits affect independence of older people. The exploration for a practical measure involving upper extremities may offer an alternative tool to be used by primary healthcare (PHC) providers for these individuals. OBJECTIVE: To explore reliability and validity of seated push-up tests (SPUTs) among older participants when used by PHC providers. METHODS: Older participants (n= 146) with an average age of > 70 years were cross-sectionally assessed using various demanding forms of SPUTs and standard measures to assess validity of the SPUTs. Reliability of the SPUTs were assessed in nine PHC raters, including an expert, health professionals, village health volunteers, and care givers. RESULTS: The SPUTs demonstrated very good agreement, with excellent rater and test-retest reliability (kappa values > 0.87 and ICCs > 0.93, p< 0.001). Moreover, the SPUT outcomes significantly correlated with lean body mass, bone mineral contents, muscle strength and mobility of older participants (r, rp⁢b=-0.270 to 0.758, p< 0.05). CONCLUSION: SPUTs are reliable and valid for older adults when used by PHC members. The incorporation of such practical measures is particularly important during this COVID-19 pandemic with limited people's hospital access.

Muscle Activity and Co-Activation of Gait Cycle during Walking in Water and on Land in People with Spastic Cerebral Palsy.

BACKGROUND: The purpose of this study was to investigate the differences in the muscle activity and co-activation index (CoA) of the rectus femoris (RF), biceps femoris (BF), gastrocnemius medialis (GM,) and tibialis anterior (TA) during walking on land and in water in healthy adolescents compared with those with spastic diplegia cerebral palsy (CP) adolescents. METHODS: Four healthy individuals (median; age: 14 years, height: 1.57 cm, BMI: 16.58 kg/m2) and nine CP individuals (median; age: 15 years, height: 1.42 cm, BMI: 17.82 kg/m2) participated in this study and performed three walking trials under both conditions. An electromyography (EMG) collection was recorded with a wireless system Cometa miniwave infinity waterproof device, and the signals were collected using customized software named EMG and Motion Tools, Inc. software version 7 (Cometa slr, Milan, Italy) and was synchronized with an underwater VDO camera. RESULTS: A significant decrease in the muscle activity of all muscles and CoA of RF/BF muscles, but an increase in TA/GM was observed within the CP group while walking in water during the stance phase. Between groups, there was a lower CoA of RF/BF and a greater CoA of TA/GM during the stance phase while walking in water and on land in the CP group. A non-significant difference was observed within the healthy group. CONCLUSION: Walking in water can decrease muscle activity in lower limbs and co-activation of thigh muscles in people with spastic CP, whereas CoA muscles around ankle joints increased to stabilize foot weight acceptance.

Effects of four-week lower limb loading training with and without augmented feedback on mobility, walking device use, and falls among ambulatory individuals with spinal cord injury: a randomized controlled trial.

PURPOSE: To compare the effects of lower limb loading training (LLLT) with or without augmented loading feedback during stepping activity on mobility, walking device use, and falls among ambulatory individuals with chronic spinal cord injury (SCI). STUDY DESIGN: Randomized controlled trial (assessor-blinded) with prospective fall data follow-up, clinical trial registration (NCT03254797). METHODS: Forty-four ambulatory participants (22 participants/group) were prospectively monitored for their baseline fall data over six months, with baseline assessments for their mobility and walking device used after six months. Then participants involved in the LLLT programs with or without loading feedback according to their groups for 30 min/day, 5 days/week, over 4 weeks. Mobility outcomes were re-assessed at week two and week four, with prospective fall data monitoring over six months, and mobility measured thereafter. RESULTS: Mobility outcomes of the participants were significantly improved from their baseline ability, especially in those who were trained using augmented feedback (the difference in main outcome, timed up and go, between the groups was 1.8 s; 95% confidence interval = 1.0-3.5s). CONCLUSIONS: LLLT during stepping activity, especially with augmented loading feedback, could be applied effectively to promote mobility and safety of ambulatory individuals with chronic SCI (post-injury time of approximately four years).

A training program of bodyweight shifting and lower limb loading training during stepping activity significantly improved mobility, walking ability, and fall rates of ambulatory individuals with chronic spinal cord injury.The improvement in those who were trained using augmented loading feedback was significantly greater than those who were trained without feedback.Such training programs may be applied to distribute effective community-based rehabilitation and home healthcare services.

Reference Values and Cutoff Scores of the Spinal Cord Independence Measure III to Determine Independence for Wheelchair Users and Ambulatory Individuals With Spinal Cord Injury.

OBJECTIVE: To establish the reference values and optimal cutoff scores of the Spinal Cord Independence Measure Version III (SCIM III) to indicate independence of wheelchair users (WU) and ambulatory (AM) individuals with spinal cord injury (SCI). DESIGN: A cross-sectional study. SETTING: Tertiary rehabilitation center and communities. PARTICIPANTS: A total of 309 (168 WU and 141 AM) participants with SCI. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE(S): SCIM III scores. RESULTS: Participants with greater levels of independence had significantly higher SCIM III scores, both total and subitem scores (P<.05). The SCIM III scores of ≥55 and ≥75 were optimal indicators of modified independence in WU and AM individuals, respectively (sensitivity and specificity >93%, AUC>.95). In addition, scores of 90 were proved to be excellent indicators for independence of AM individuals (sensitivity 94%, specificity 100%, AUC=.99). CONCLUSIONS: The present findings provide the reference values of SCIM III scores covering WU and AM individuals with SCI at various levels of independence as well as optimal cutoff scores to indicate independence of these individuals. These data can be used as standard criteria for data comparison with patients' ability, and target functional values for individuals with SCI in clinical-, community-, and home-based settings.

Validity and feasibility of a seated push-up test to indicate skeletal muscle mass in well-functioning older adults.

INTRODUCTION: Skeletal muscle mass (SMM) is a major component of the human body (> 30% of the body-weight) and plays crucial role in many bodily functions. However, SMM assessments require a complex and costly machine, which delays the ability to detect abnormalities related to SMM decline and, subsequently, reduces the effectiveness of the clinical management of older adults. PURPOSE: This study aimed to: 1) assess the correlation between upper limb loading during a seated push-up test (ULL-SPUT) and SMM (concurrent validity); 2) compare the SMM of participants who passed and failed a seated push-up test (SPUT; discriminant validity); and 3) explore the ability of a failed SPUT to identify older individuals with low SMM. METHODS: Participants (n = 40, age approximately 73 years) were cross-sectionally assessed for their SMM using a portable bioelectrical impedance analysis, and SPUTs were evaluated using digital push-up loading devices that were the size of clinical push-up boards, in three starting positions: 1) high; 2) ring, and 3) long sitting positions. RESULTS: The ULL-SPUT, especially in a ring sitting position, was significantly correlated to SMM (rs = 0.457-0.608, p < .005). The SMM and ULL-SPUT were significantly different between participants who passed and failed the SPUT (p < .05). Failure to complete the SPUT - that is, being unable to lift the body up from the floor during the test - showed an excellent ability to indicate participants with an SMM of < 28% of their body-weight (sensitivity > 83%, specificity > 82%, area under the curve = 0.93). CONCLUSIONS: The inability to lift the body up from the floor during sitting using the upper limbs can be used as a screening tool to indicate those with low SMM. Such a simple screening measure may enhance the distribution of healthcare services across various community- and home-based settings, particularly during the coronavirus (COVID-19) pandemic, when hospital services are limited for many individuals, including older adults.

Responsiveness and minimal clinically important difference of the five times sit-to-stand test in ambulatory individuals with spinal cord injury: A six-month prospective cohort study.

OBJECTIVES: To explore the responsiveness and minimal clinically important differences of the five times sit-to-stand test in ambulatory individuals with spinal cord injury. METHODS: This six-month prospective cohort study was conducted in 109 individuals with spinal cord injury who could walk with or without a walking device for at least 10 meters. Participants were assessed for the five times sit-to-stand test in the four arm-placement conditions and standard measures to determine responsiveness of the test, at baseline, and one, three, and six months. At six months, participants were also interviewed for the global rating of change to estimate the minimal clinically important differences of the five times sit-to-stand test. RESULTS: The five times sit-to-stand test showed large internal responsiveness (standardized response means>0.83), with moderate external responsiveness as compared to the 10-meter walk test (ρ = -0.28 to -0.48, p < 0.005). The changes in the outcomes >2.27 and >2 s could be used to indicate a level of minimal clinically important change for participants who executed the test with and without hands, respectively. CONCLUSION: The five times sit-to-stand test is a responsiveness measure for ambulatory individuals with spinal cord injury. The levels of minimal clinically important differences found in this study (>2.27 and >2 s) can be applied as a useful benchmark for the decision of clinically relevant changes over time for these individuals.

The 7th cervical vertebra wall distance (C7WD) identifies balance control, functional mobility and the risk of multiple falls in elderly community-dwelling women with thoracic hyperkyphosis.

BACKGROUND: Thoracic hyperkyphosis is common in the elderly, especially in women, and results in impaired balance control, impaired functional mobility and an increased risk of multiple falls. The 7th cervical vertebra wall distance (C7WD) is a practical method for evaluating thoracic hyperkyphosis. OBJECTIVE: This study calculated C7WD cut-off scores that may identify impaired balance control, impaired functional mobility and an increased risk of multiple falls in elderly community-dwelling women with thoracic hyperkyphosis. This study also explored the correlation between C7WD, balance control and functional mobility. METHODS: Sixty participants were assessed for thoracic hyperkyphosis using the C7WD, balance control using the functional reach test (FRT), functional mobility using the timed up-and-go test (TUG) and a history of falls using their personal information. RESULTS: The data indicated that a C7WD of at least 7.95 cm, 8.1 cm and 8.8 cm had a good to excellent capability of identifying impaired balance control, impaired functional mobility and an increased risk of multiple falls, respectively. The C7WD results were significant and correlated with balance control (rs=-0.68) and functional mobility (rs= 0.41). CONCLUSIONS: The C7WD may be utilised as a screening tool for these three impairments in this population.

Knee Extensor Muscle Strength to Measure the Ability of Five Times Sit to Stand Independently in Patients with Incomplete Spinal Cord Injury.

Background: Patients with incomplete spinal cord injury (iSCI) and lower extremity muscle weakness often fall while standing up from a chair. The sit-to-stand (STS) task primarily uses the strength of the knee extensor muscles. The five times sit-to-stand test (FTSST) is often applied to determine lower limb function and the results are related to lower extremity muscle strength. This study explored the cut-off point for knee extensor muscle strength in patients with iSCI to independently determine their FTSST results and the correlation between knee extensor muscle strength and FTSST results. Methods: Forty-four participants were assessed for knee extensor muscle strength using a hand-held dynamometer (HHD) and the FTSST. Results: The data indicated that knee extensor muscle strength ≥ 53.06 Newton was the best independent predictor of the FTSST results (sensitivity 72.7%, specificity 72.7%). Moreover, knee extensor muscle strength was significant and correlated with the FTSST results (r = -0.45, P = 0.035). Conclusion: The findings offer a cut-off point for the knee extensor muscle strength measured while standing up from a chair that may help medical professionals set rehabilitation goals for patients with iSCI.

Reliability and concurrent validity of the Spinal Cord Independence Measure III among rehabilitation professionals.

STUDY DESIGN: A cross-sectional design. OBJECTIVES: To investigate rater reliability of the Spinal Cord Independence Measure or SCIM III among rehabilitation professionals, along with the concurrent validity of the tool as compared to standard measures covering wheelchair users (WU) and ambulatory (AM) individuals with spinal cord injury (SCI). SETTING: A tertiary rehabilitation center and communities. METHODS: Eighty-two participants with SCI (39 WU and 43 AM individuals) were assessed using SCIM III items. The data of first 30 participants were video recorded for rater reliability assessments by seven rehabilitation professionals, including nurses, occupational therapists, and physical therapists (one novice and one experienced rater for each professional). All participants were also assessed using standard measures to verify concurrent validity of SCIM III by an experienced rater. RESULTS: The SCIM III showed excellent intra-rater and inter-rater reliability among rehabilitation professionals when analyzed for overall items (intraclass correlation coefficient (ICC) >0.90) and separately for each subscale (kappa values >0.80). The total SCIM III of WU and the mobility scores of AM participants showed significant correlation with standard measures for muscle strength, limit of stability, balance control, functional endurance, and walking ability (rs = 0.343-0.779; p < 0.05). CONCLUSIONS: The present findings extend clinical benefit and confirm the use of SCIM III interchangeably among rehabilitation professionals after they have been adequately trained. The findings are important for community-based rehabilitation and home healthcare services, especially during the coronavirus (COVID-19) pandemic, when hospital beds and in-patient services are limited for individuals with SCI.

Ability to detect history of falls among individuals with spinal cord injury using upper limb loading during a seated push-up test.

BACKGROUND: A history of falls is an important risk factor for future falls, including for individuals with spinal cord injury (SCI) who often experience falls and subsequent injuries. This may be even more pronounced during the current COVID-19 pandemic because of the extreme shortage of hospital admission and restricted access to important services. Therefore, the ability of detecting a history of falls that can be applied to wheelchair users and ambulatory individuals with SCI in various settings are essential. AIM: To investigate the discriminative ability of three clinical measures-the handgrip (HG) test, Spinal Cord Independence Measure (SCIM) III and Upper Limb Loading During a Seated Push-Up Test (ULL-SPUT)-in discriminating individuals with SCI with and without a history of falls over the past six months. DESIGN: A 6-month retrospective observational cohort study. SETTING: Inpatient tertiary rehabilitation center. POPULATION: One hundred and fourteen wheelchair users and ambulatory individuals with SCI. METHODS: The participants were interviewed and assessed for their demographics, SCI characteristics and fall data over the past six months, with data confirmation from related events, their caregivers and medical records. Subsequently, they were assessed using the HG test, SCIM III, and ULL-SPUT. RESULTS: In total, 29 participants (25%) fell during the past six months (with the number of falls ranging from 1-20, with minor consequences after the falls). Among the three clinical measures assessed in this study, the ULL-SPUT data of faller participants were significantly higher than those of non-fallers (P<0.05). CONCLUSIONS: The limited rehabilitation length and increased staying home and social isolation prompted by the COVID-19 pandemic may have reduced the fall rates of the participants. The findings suggest a higher likelihood of falls among wheelchair users and ambulatory individuals with SCI who have good mobility as determined using ULL-SPUT data. CLINICAL REHABILITATION IMPACT: Apart from being an important rehabilitation strategy, the present findings suggest an additional benefit of ULL-SPUT to identify individuals with SCI with a likelihood of future falls. The measurement can be done easily using digital bathroom scales placing over a flat and smooth surface. Therefore, it would enable the timely initiation of fall prevention strategies in various clinical, community, home and research settings; particularly in this COVID-19 pandemic of limited beds and hospital services for these individuals.

Validity and feasibility of using a seated push-up test among community-dwelling older adults.

Background: Older individuals face a high risk of mobility and body composition decline, which can affect their independence. In light of a current uncertain healthcare situation created by the coronavirus (COVID-19) pandemic, healthcare paradigm has been shifted with increased demand for a practical measure to promote standard home healthcare services for all individuals, including older adults. Objective: This study explored the feasibility and validity of seated push-up tests (SPUTs) as clinical measures to reflect the body composition, muscle strength, and mobility among community-dwelling older individuals, aged ≥65 years (n=82). Methods: Participants were cross-sectionally assessed using SPUTs with various demanding forms, including the 1-time SPUT (1SPUT) along with its upper limb loading SPUT (ULL-SPUT), 5-time SPUT (5SPUT), 10-time SPUT (10SPUT), and 1-min SPUT (1minSPUT) and standard measures. Results: Participants who passed and failed a 1SPUT showed significant differences in the outcomes of all standard measures (p<0.05). The ULL-SPUT significantly correlated to all body composition, muscle strength, and mobility (r=0.247-0.785; p<0.05). Outcomes of 1minSPUT significantly correlated with muscle strength and mobility outcomes (r=0.306-0.526; p<0.05). Participants reported no adverse effects following the SPUTs. Conclusion: The findings suggest the use of the 1SPUT, ULL-SPUT, and 1minSPUT as practical measures to reflect the body composition, muscle strength, and mobility of older individuals, according to their functional levels. The tests may especially clinically benefit those with lower limb limitations and those in settings with limited space and equipment.

Outcomes of the five times sit-to-stand test could determine lower limb functions of ambulatory people with spinal cord injury only when assessed without hands.

Context/Objectives: Various clinical application of the five times sit-to-stand test (FTSST), with or without hands, may confound the outcomes to determine the lower limb functions and mobility of individuals with spinal cord injury (SCI). This study assessed the concurrent validity of the FTSST in ambulatory individuals with SCI who completed the test with or without hands as verified using standard measures for lower extremity motor scores (LEMS) and functional mobility necessary for independence and safety of these individuals.Design: Cross-sectional study.Setting: Tertiary rehabilitation centers and community hospitals.Participants: Fifty-six ambulatory individuals with motor incomplete SCI who were able to walk independently with or without a walking device over at least 10 m.Outcome Measures: Time to complete the FTSST with or without hands according to individuals' abilities, LEMS, and functional mobility.Results: Time to complete the FTSST showed moderate-to-strong correlation with the LEMS scores and all functional mobility tests (ρ = -0.38 to -0.71, P < 0.05), but only in those who performed the test without hands. By contrast, data of those who completed the FTSST with hands were significantly correlated only with the ankle muscle strength and the functional mobility measures that allow upper limb contribution in the tests (ρ = -0.40 to 0.52, P < 0.05).Conclusion: Upper limb involvement could confound the outcomes of the FTSST. The present findings suggest the use of FTSST without hands to determine the lower limb functions of ambulatory individuals with SCI.
