RESUMO

PURPOSE OF THE STUDY We aimed to investigate the functional outcomes and complications of a new approach, the primary UCL repair using JuggerKnot™ Soft Anchor-1.0 mm Mini (Zimmer-Biomet). MATERIAL AND METHODS This study included a total of 12 patients with acute UCL injury who were operated with primary repair with JuggerKnot™ Soft Anchor-1.0 mm Mini between January 2012 and September 2016. All patients were operated on using the same surgical technique. The thumb pinch and grip strengths, articular range of motion, and Glickel functional score were recorded for all patients. The pinch grip strength and articular range of motion were compared with the intact side. Early and late postoperative complications were recorded. RESULTS The mean follow-up time was 22.2 months (range 6-54 months). The grip strength and the pinch strength were 94.3% and 92.27%, respectively, of the contralateral side. Articular range of motion attained the same level as the contralatereal side in all patients at the final visit, and no patient suffered from any complication. The patients returned to work at a mean of 5.45 weeks, and the Glickel score was good in 1 patient and excellent in the remainder 11 patients. CONCLUSIONS Surgical repair using the JuggerKnot™ Soft Anchor-1.0 mm is an effective alternative treatment method for acute total ulnar collateral ligament (UCL) rupture. Key words:ulnar collateral ligament, acute total injury, thumb, soft suture anchor, JuggerKnot™.

RESUMO

Evidence suggests that mental health is associated with multiple factors such as physical activity, sedentary behavior, and physical function in older adults. The present study used latent profile analysis to identify classes of older adults based on their health profile among a representative sample of Korean older adults with hypertension. Differences in mental health between these classes were also examined.Seven hundred and sixty seven participants (mean age = 70.23, SD = 6.08; men 45.6%) were included in the analysis.There were 3 latent classes (class 1: a physically inactive lifestyle with low physical function and body perception; class 2: a physically moderate lifestyle with moderate physical function and low body perception; class 3: a physically active lifestyle with high physical function and body perception). According to class comparisons, older adults in class 3 had significantly lower anxiety/depression levels than classes 1 and 2. Older adults in class 3 had significantly lower stress levels than class 1.It is possible that among older adults, having a positive attitude of one's body shape may also be important for improving anxiety/depression along with having a physically active lifestyle and maintaining physical function.

RESUMO

AIMS: The aim of this study was to investigate whether clinical and radiological outcomes after intramedullary nailing of displaced fractures of the fifth metacarpal neck using a single thick Kirschner wire (K-wire) are noninferior to those of technically more demanding fixation with two thinner dual wires. PATIENTS AND METHODS: This was a multicentre, parallel group, randomized controlled noninferiority trial conducted at 12 tertiary trauma centres in Germany. A total of 290 patients with acute displaced fractures of the fifth metacarpal neck were randomized to either intramedullary single-wire (n = 146) or dual-wire fixation (n = 144). The primary outcome was the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire six months after surgery, with a third of the minimal clinically important difference (MCID) used as the noninferiority threshold. Secondary outcomes were pain, health-related quality of life (EuroQol five-dimensional questionnaire (EQ-5D)), radiological measures, functional deficits, and complications. RESULTS: Overall, 151/290 of patients (52%) completed the six months of follow-up, leaving 83 patients in the single-wire group and 68 patients in the dual-wire group. In the modified intention-to-treat analysis set, mean DASH scores six months after surgery were 3.8 (sd 7.0) and 4.4 (sd 9.4), respectively. With multiple imputation (n = 288), mean DASH scores were estimated at 6.3 (sd 8.7) and 7.0 (sd 10.0). Upper (1 - 2α)) confidence limits consistently remained below the noninferiority margin of 3.0 points in the DASH instrument. While there was a statistically nonsignificant trend towards a higher rate of shortening and rotational malalignment in the single wire group, no statistically significant differences were observed across groups in any secondary outcome measure. CONCLUSION: A single thick K-wire is sufficient for intramedullary fixation of acute displaced subcapital fractures of the fifth metacarpal neck. The less technically demanding single-wire technique produces noninferior clinical and radiological outcomes compared with the dual-wire approach.

RESUMO

INTRODUCTION: Sarcopenia is associated with a higher risk of adverse outcomes among hospitalized patients with chronic diseases. Currently, an unmet need lies in its low diagnostic yield. We conducted a pilot study with the aim to screen hospitalized patients for sarcopenia using the EWGSOP2 criteria. PATIENTS AND METHODS: A cross-sectional study among hospitalized patients in internal medicine was carried out, inclusion criteria: age>55, ability to stand-up from a chair. EXCLUSION CRITERIA: bed-bound, terminal stages of the disease, ICU stay. We measured hand-grip strength, fat-free mass by bioimpedance and short physical performance battery test (SPPB). Sarcopenia was diagnosed in low hand-grip strength and low muscle mass (EWGSOP2), severe sarcopenia in sarcopenic patients with low physical performance (SPPBT≤8). RESULTS: 40 patients were enrolled, sarcopenia was diagnosed in 8/20 (40%) men and 3/20 (15%) women (p=0.15), severe sarcopenia in 6/20 men (30%) and 2/20 (10%) women (p=0.24). 65% of men and 40% of women had SPPBT≤8, and 60% of men and 55% of women had gait speed≤0.8m/s. CONCLUSION: Among hospitalized internal medicine patients sarcopenia and severe sarcopenia are common, particularly in males. New diagnostic criteria provide a relatively simple and applicable tool for screening among internal medicine inpatients (Tab. 3, Ref. 25).

RESUMO

Aims: The study aimed to assess the percentage difference of hand dimensions and their correlation with grip and pinch strength among school children in Saudi Arabia. Materials and Methods: Anthropometric measurements, hand dimensions, grip, and pinch strength measurements were obtained from 200 healthy schoolchildren in both genders aged 6-16 years. A Jamar electronic handgrip dynamometer was used to measure handgrip strength in kg. Pinch dynamometer was used to measure the two-point pinch strength, three-point pinch strength and lateral pinch strength in kg. Hand circumference was measured following hand arch at the maximum palm level. Hand span from the tip of the thumb to the tip of the little finger with the hand opened as broad as possible. Hand length from the tip of the middle finger to the midline of the distal wrist crease. Palm length from the distal wrist crease to the base of the middle finger. Results: The percentage of difference of hand dimensions between both the genders was statistically significant. Both handgrip and pinch strength were significantly correlated with anthropometric measurements and hand dimensions. Body mass index had mild correlation with both handgrip strength and pinch strength (P < 0.05). Age, hand circumference, hand span, hand length and palm length had moderate to strong correlation with both grip and pinch strength (P < 0.01). Conclusion: The current study provides a source of perspective reference values in clinical settings for hand dimensions. The present study showed significant correlations with handgrip and pinch grip strengths among schoolchildren in Saudi Arabia.

RESUMO

Objective: To examine the association between long-term exposure to ambient PM(2.5) combined with indoor air pollution and handgrip strength among people aged 50 and over. Methods: Data were from the first wave of World Health Organization Study on global AGEing and adult health in China. Ambient annual concentration of PM(2.5) was estimated by using the satellite data we also investigated the use of fuels and chimneys as indoor air pollution. A two-level (individual level and community level) linear model was applied to examine the association between long-term exposure to ambient PM(2.5) combined with indoor air pollution and the handgrip strength. Results: A total of 13 175 individuals aged 50 years and over were included for analysis. The handgrip strength was (26.67±0.54) kg. Ambient PM(2.5) was found to be significantly associated with the risk of decreased handgrip strength. Outdoor PM(2.5) concentration was negatively correlated with handgrip strength (ß=-0.23, 95%CI: -0.31 - -0.14) decrease in handgrip strength after adjusting for gender, age, residence, education, household assets, intake of vegetables and fruits, smoking and drinking, physical activity. In rural area, compared to those who used solid fuel, use of clean fuel increased (ß=1.41, 95%CI: 0.36-2.46) handgrip strength. But in urban area, we did not find any statistically significant association between the use of clean fuel and handgrip strength (ß=0.19, 95%CI: -0.95-1.32). Conclusion: This study found that long-term exposure to ambient PM(2.5) combined with indoor air pollution was significantly associated with low handgrip strength among people aged 50 years and over, this suggested that ambient PM(2.5) might serve as one of the risk factors for low physical function seen in the people aged 50 years and over.

RESUMO

INTRODUCTION: Winter pruning is a cultivation practice necessary for maintaining the balance between the vegetative and the productive activity of plants and requires many working days using hand scissors. This operation involves the subjects carrying out a series of gestures that are repeated with considerable frequency, which are all musculo-skeletal disorders risk factors (MSDs) for the hand-wrist area. OBJECTIVE: The aim of this study was to investigate the forces applied to pruning tools. MATERIAL AND METHODS: Using a sensor matrix, peak and average forces were measured which are exerted while cutting branches of 3 different diameters, from 5 wine-grape cultivars. Samples were tested on 8 participants using sensored scissors to record, in 6 hand areas, the forces necessary to cut. RESULTS: Results showed that while cutting, the factors which can impact the force employed (peak and average forces) by the subjects are branch diameter and percentage of branch humidity. Cut duration was inversely related to the size of the subject's hand. The middle finger area of the hand recorded the highest force average and peak levels, while the hand region least affected during the cuts was the farthest from the thumb. CONCLUSIONS: The study enabled the highlighting of which factors influence the forces employed by the operator while cutting grape branches, and to identify the hand regions where muscle activation is at its most. These findings can be relevant in preventing MSDs. Further studies need to be conducted with a larger number of subjects.

RESUMO

This work aimed to assess the role of manual laterality in action coding strategies and, subsequently, in environmental features relevant for each hand's action. Relying on Eder and Hommel's (2013) proposal, we distinguished stimulus-related and end state-related consequences in a Simon paradigm where right-handed participants were divided into two groups, one responding with gloves and one without. Two objects were presented pictorially: one for which sensory consequences of grasping were negatively valenced (a chestnut burr), and one for which they were positively valenced (an apricot). By these means, stimulus and end-state effects could be assessed separately, along with the relevance of each feature of the experimental settings. Results showed that the use of one's dominant or non dominant hand gives rise to different repercussions of stimulus-related and end state-related effects on response: Responses made with the right (dominant) hand were based on an elaborated coding (representing features of stimulus-related and end state-related consequences of action). In contrast, responses made with the left (non dominant) hand seemed to be based on a less elaborated coding (not taking into account end-state consequences of an action).

RESUMO

Sarcopenia remains poorly managed in clinical practice due to the lack of simple and accurate screening tools. This study aimed to identify the cutoff values of the SARC-F questionnaire and Ishii's score using the variables age, grip strength, and calf circumference in older inpatients in China to compare the accuracy of the two methods and to explore their predictive ability for adverse outcomes (rehospitalization, falls, fracture, and death). Hospitalized patients (n=138) aged ≥60 years were included. The accuracy of the two tools was evaluated using the reference diagnosis recommended by the Asian Working Group on Sarcopenia (assessing patients with measurements of muscle mass, handgrip strength, and usual gait speed). Follow-up data were obtained by telephone and clinical visits combined with the inpatient medical record system after discharge for at least one year. The results showed that the SARC-F score reached the highest Youden's index when a score of 3 was set as the cutoff value. Ishii's score presented a higher accuracy than SARC-F (area under the receiver operating curve: 0.78 vs 0.64, P=0.01). The Kaplan-Meier survival analysis demonstrated a higher cumulative incidence of rehospitalization in sarcopenic individuals compared to non-sarcopenic individuals according to SARC-F (log-rank test, P<0.001). Cox analysis revealed that SARC-F was an independent risk factor for rehospitalization (adjusted hazard ratio: 4.23, 95%CI: 2.12-9.79, P<0.001). The SARC-F and Ishii's scores might facilitate the early detection of sarcopenia and help identify older adults at risk for adverse outcomes in clinical practice.

RESUMO

Objectives: Recent evidence suggests an association between functional capacity and cognitive function, at least in older adults. The aim of this cross-sectional study was to examine the association between cognitive function, functional capacity, isokinetic leg strength, health-related quality of life (HRQOL), sleep quality, body fat, handgrip strength, and fatigue among a sample of MS patients. Methods: Fifty-one relapsing-remitting MS patients (age: 38.4 ± 7.1 yrs; 30 females) were recruited and agreed to participate in this study. Cognitive function was assessed by the Paced Auditory Serial Addition Test (PASAT). Functional capacity was examined using various functional tests commonly used in MS patients. Maximal voluntary unilateral leg strength was assessed using isokinetic dynamometer. Isometric handgrip strength was assessed by a dynamometer. Total body and visceral fat levels were assessed via bioelectrical impedance analyzers. Finally, the patients' HRQOL, sleep quality, and fatigue levels were evaluated using specific questionnaires. Results: A significant association was found between the PASAT score and the performance score in various functional capacity tests (p < 0.050). On the other hand, a weak but statistically significant association was found between the PASAT score and isokinetic strength of knee extensors (r = 0.319, p = 0.022) and knee flexors (r = 0.354 p = 0.011). Poor sleep quality was associated with lower performance in all the functional capacity tests examined (p < 0.05) whilst was negatively associated with the PASAT score (r = -0.334, p = 0.017). The multivariate regression analysis revealed that the performance on the TUG test was a significant predictor of cognitive function. Conclusion: Based on the results of this study, functional capacity was found to be associated with both impaired cognitive performance and low HRQOL in MS patients. In addition, an association between sleep quality and cognitive performance was revealed, confirming existing literature. Functional capacity as assessed by the TUG test emerged as the best predictor of cognitive function.

RESUMO

OBJECTIVES: This study aims to evaluate the clinical and radiological results of patients with multiple dorsal carpometacarpal (CMC) joint fracture dislocations treated with open reduction and internal fixation (ORIF). PATIENTS AND METHODS: We evaluated 14 patients (12 males, 2 females; mean age 35.1 years; range, 22 to 64 years) between January 2013 and December 2017. Our main outcome measurements were the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, loss of grip strength, limitation of range of motion (ROM), and Kellgren-Lawrence osteoarthritis classification identified with radiographs and computed tomography images. RESULTS: The mean QuickDASH scores at seventh week and third month were 73.57 (range, 65-90) and 29.11 (range, 25-42.5), respectively. The mean QuickDASH score at seventh, ninth, and 12th month, and final follow-up was 4.64 (range, 0-30) and the QuickDASH score at these follow-up points was not 0 for only three patients. The mean loss of grip strength was 32.14% and two patients (14.29%) had limitation of ROM in third proximal interphalangeal joint at final follow-up. Four patients had grade I, nine patients had grade II, and one patient had grade III osteoarthritis according to Kellgren-Lawrence classification at final follow-up. CONCLUSION: Although functional results demonstrated that multiple CMC joint fracture dislocations can be treated with ORIF, the high rate of osteoarthritis is a disadvantage.

RESUMO

PURPOSE: Muscle mass, strength, and composition determine muscle quantity and quality. However, data on muscle properties in relation to bone mass or insulin resistance are limited in Asian populations. This study aimed to investigate the relative importance of muscle measurements in regards to their relationship with lower bone mass and insulin resistance. MATERIALS AND METHODS: In this study, 192 postmenopausal women (age, 72.39±6.07 years) were enrolled. We measured muscle cross-sectional area (CSA) and attenuation at the gluteus maximus and quadriceps muscles through quantitative computed tomography. Muscle strength and physical performance were evaluated with the hand grip test and Short Physical Performance Battery (SPPB). Pearson correlation analysis and linear regression were performed to evaluate the relationship between muscle properties and homeostatic model assessment-insulin resistance (HOMA-IR) or bone mineral density (BMD). RESULTS: Muscle CSA, hand grip strength, and SPPB score held positive correlations with spine and hip BMDs, but not with insulin resistance. In contrast, muscle attenuation of the gluteus maximus or quadriceps was inversely related to HOMA-IR (r=-0.194, p=0.018 and r=-0.292, p<0.001, respectively), but not BMD. Compared with the control group, muscle CSA was significantly decreased in patients with osteoporosis; however, decreased muscle attenuation, indicating high fat infiltration, was found only in patients with diabetes. CONCLUSION: Muscle mass, strength, and physical performance were associated with low bone mass, and accumulation of intramuscular fat, a histological hallmark of persistently damaged muscles, may play a major role in the development of insulin resistance in Korean postmenopausal women.

RESUMO

OBJECTIVE: This study investigated the most appropriate intertrial rest period for maximum grip and key pinch strength measurements involving three trials. METHOD: The study included 40 male and 40 female participants. Using a repeated-measures design, six intertrial rest periods-15 s, 30 s, 60 s, 90 s, 120 s, and 150 s-were investigated, one per day on 6 different days. RESULTS: A repeated-measures analysis of variance or Friedman test found significant decreases in grip and key pinch strength over the three trials in all test conditions. However, for both hands, only small differences were observed in test conditions (≥90 s, male grip; ≥60 s, female grip; male and female key pinch; effect sizes of <0.5). CONCLUSION: If a rest of ≥150 s is not possible, 90 s of rest between trials for grip strength and 60 s of rest between trials for key pinch strength can be considered.

RESUMO

BACKGROUND: The combined association of physical activity and sedentary behavior with adverse health factors is not yet clear in the literature. A combined analysis of physical activity level and sedentary behavior may provide evidence of the interrelation between these behavioral variables and the frailty syndrome. Thus, the aim of this study was to examine the relationship between physical activity level, sedentary behavior and frailty in older adults. METHODS: In this study, we evaluated 457 older adults (age range = 60 to 96 years old) from the Longitudinal Study of the Elderly Health of Alcobaça, Bahia. The frailty condition was defined by the presence of three or more of the following criteria: unintentional weight loss, slow walking speed measured over a 4.57 m test, a reduction of manual grip strength and exhaustion. Based upon these criteria, participants were classified as non-frail or frail. Physical activity level and time spent in sedentary behavior were assessed with the International Questionnaire of Physical Activity. Descriptive statistics were used to characterize the sample. To examine the combined association of physical activity and sedentary behavior with frailty, chi-square and Poisson regression tests were used. Statistical significance was defined as p ≤ 0.05. RESULTS: The prevalence of frailty was 8.8% (n = 40), with higher prevalence observed with increasing age. Low physical activity level combined with excessive time spent in sedentary behavior (physical activity level < 150 min/wk. and sedentary behavior ≥540 min/day) was associated with frailty, resulting in a prevalence ratio of 2.83 (95% CI, 1.23 to 6.52). CONCLUSION: Frailty is more prevalent among older adults who exhibit insufficient levels of physical activity combined with a great amount of time spent in sedentary behavior, even when adjusted for sociodemographic factors.

RESUMO

The interaction between different muscles needed to perform specific tasks with our hands is more complicated than one might think. We have composed a tablet-based model that is intended to motivate users to "design" specific functional grips making weighted use of the available tools, i. e. the extrinsic forearm and intrinsic hand muscles. The solutions provided for the various tasks are not exhaustive as there is no validated database for most non-standard grips. Our motivation for creating this model was to contribute to further education and to add fun to our daily work.

RESUMO

OBJECTIVES: The primary purpose of this study was to determine the time-varying associations between decreased handgrip strength (HGS) and individual instrumental activities of daily living (IADL) impairments for a nationally-representative sample of aging adults in the United States. DESIGN: Longitudinal-Panel. SETTING: Detailed interviews were completed in person and core interviews were typically completed over the telephone. PARTICIPANTS: A total of 15,336 participants aged at least 50 years who participated in the 2006 wave of the Health and Retirement Study were followed biennially for 8-years. MEASUREMENTS: A hand-held dynamometer assessed HGS and performance in IADLs were self-reported. RESULTS: Every 5-kilogram decrease in HGS was associated with an increased odds ratio for the following IADL impairments: 1.11 (95% confidence interval (CI): 1.09, 1.13) for using a map, 1.10 (CI: 1.07, 1.12) for grocery shopping, 1.09 (CI: 1.05, 1.14) for taking medications, 1.07 (CI: 1.05, 1.09) for preparing hot meals, 1.06 (CI: 1.04, 1.08) for managing money, and 1.05 (CI: 1.02, 1.09) for using a telephone. CONCLUSIONS: Decreased HGS was associated with each IADL impairment, and slightly different associations were observed in individual IADL tasks for aging adults in the United States. Our findings suggest that decreased HGS, which is reflective of reduced function of the neuromuscular system, is associated with diminished performance in autonomous living tasks during aging. Losses in HGS may lead to the development of an IADL impairment. Therefore, health-care providers working with aging adults should utilize measures of HGS as a screening tool for identifying future deficits in neuromuscular functioning. Interventions designed to preserve IADLs in aging adults should also include measures of HGS for detecting early changes in IADL capacity, and intervening at the onset of HGS declines may help aging adults retain their ability to live autonomously.

RESUMO

BACKGROUND: Urinary incontinence (UI) is known to be more prevalent among women and is associated with decline in quality of life. The aim of our study was to investigate the prevalence, risk factors of urinary incontinence and its impact on quality of life among community dwelling older women living in urban and rural populations. METHODS: This study was conducted based on secondary data analysed from the third phase of the longitudinal study "Neuroprotective Model for Health Longevity among Malaysian Elderly" (LRGS TUA). Stratification of urban and rural study areas were in accordance to that determined by the Department of Statistics. A total of 814 community dwelling older women (53% urban, 47% rural), aged 60 years and above, across four states within Peninsular Malaysia were included in this analysis. Interview-based questionnaires were used to obtain respondents' sociodemographic details and clinical characteristics. The Timed Up and Go test and Handgrip Strength tests were used to assess physical function. Urinary incontinence was self-reported, and quality of life of those with incontinence was assessed using the King's Health Questionnaire (KHQ). RESULTS: Prevalence of urinary incontinence was 16% and 23% among older women living in urban and rural areas, respectively. Ethnicity was significantly associated with incontinence among older women in both urban and rural population (p < 0.05). Chronic constipation, functional mobility and muscle strength were associated with UI in participants from rural setting (p < 0.05). Binary logistic regression analysis showed that risk of incontinence is lower among Chinese [OR 0.430, 95% C.I: 0.224-0.825, p = 0.011] compared to Malay older women living in urban population. Within the rural population, respondents with chronic constipation [OR: 3.384, 95% C.I: 1.556-7.360, p = 0.002] were found to be at a higher risk of UI. In terms of quality of life, respondents in rural areas experienced more role, physical, social, emotional limitations and sleep disturbance as compared to their urban counterparts (p < 0.05). CONCLUSION: UI is more prevalent and had a more profound impact on quality of health among older women in the rural setting. The risk factors of UI were ethnicity and chronic constipation among urban and rural older women respectively. It is important to provide holistic strategies in the prevention and management of UI among older women especially within the rural population.

RESUMO

BACKGROUND: Exercise may modify disease progression in persons with Parkinson disease (PD). OBJECTIVE: The purpose of this longitudinal cohort study was to determine factors that predict motor, activity, and participation-based outcomes over two years in exercisers with PD. METHODS: A convenience sample with idiopathic PD was included in the analysis [n = 74; mean age 66.7(8.4) years; male 54%; median months post diagnosis 69.0(76.0), median Hoehn and Yahr score 1.0(2.0)]. Exercise behaviors (minutes of exercise/week, peak rate of perceived exertion (RPE) and mode of exercise) and outcomes of impairment [grip strength], activity [10-meter walk test, functional reach test, activity specific balance confidence scale] and participation [Parkinson Disease Questionnaire-39] were assessed at baseline, 6, 12, 18 and 24 months. RESULTS: Using generalized estimating equations at least one exercise behavior was a significant predictor across most of the models (p≤0.026), with higher RPE predicting better outcomes in all activity and participation domains. Younger age, male gender and lower disease severity also significantly predicted better outcomes over time (p≤0.041). CONCLUSIONS: Exercise behaviors contributed to activity and participation-based outcomes over two years in exercisers with PD. Participation in high-intensity exercise programs may enhance maintenance of health and function over time in individuals with PD.

RESUMO

Background: Sarcopenia is typically defined as the loss of muscle mass, strength and low physical performance with aging. Ultrasound is a safe and easy method for evaluating muscle mass and quality by muscle thickness (MT) and pennation angle (PA), respectively. Although the positive correlations between MT and muscle mass and handgrip strength were observed, the relationship between MT, PA and physical performance remains unclear. Purpose: This study aimed to investigate the correlation of aforementioned ultrasound parameters with muscle mass, muscle strength and physical performance and explore the utility of ultrasound in predicting sarcopenia. Patients and methods: A total of 265 elderly Chinese community dwellers were included. MT of both forearm and lower leg as well as PA of gastrocnemius was assessed by ultrasound. Muscle mass was assessed by dual-energy X-ray absorptiometry. Muscle strength was measured by a Jamar hand dynamometer. Physical performance was assessed by the Short Physical Performance Battery (SPPB). Results: Anterior radial MT in men and regional MTs except posterior fibula in women were negatively correlated with the age. No significant correlation was observed between PA and the age in both genders. Posterior tibial MT and posterior fibula MT were positively correlated with the relative appendicular skeletal muscle mass in men and women, respectively. Anterior ulnar MT was positively correlated with grip strength in both genders. Moreover, gastrocnemius medialis PA showed a positive association with gait speed and SPPB in women but not in men. Conclusion: A combination of posterior fibula MT, anterior ulnar MT and gastrocnemius medialis PA measured by muscle ultrasound is helpful for the assessment of sarcopenia in Chinese elderly women. In addition, a combination of posterior tibial MT and anterior ulnar MT measured by muscle ultrasound is helpful for the assessment of sarcopenia in Chinese elderly men.
