The role of quadriceps muscle strength in the development of falls in the elderly people, a cross-sectional study

Abstract Introduction: Regular physical activity is one of the main ways of avoiding compromised functional capacity and gaining muscle mass. Objective: investigate the differences in muscle strength and functional capacity of elderly people engaged in two types of strength exercises. Method: a cross-sectional study of 80 seniors of both sexes, 40 of whom engaged in weight training and 40 from the Fitness Zone in the city of Maringá, Paraná, state. A sociodemographic questionnaire, the sitting-rising and elbow flexion tests, and the functional capacity tests of the Latin American Development Maturity Group (GDLAM) were applied. The data were analyzed using the Shapiro-Wilk, Mann-Whitney “U” and Spearman’s correlation tests (p<0.05). Results: Most seniors who performed well in the sitting and rising test, rising from a chair and moving around the house and rising from the dorsal decubitus position engaged in weight training (p=0.001). Those engaged in weight training exhibited better upper limb strength and functional capacity in all the tests performed (p <0.05). Muscle strength is inversely related to functional capacity, that is, the better the result in the upper and lower limb muscle strength tests, the better the functional capacity of the elderly engaged in weight training. Conclusion: According to the results obtained, older people who engage in weight training display better upper limb strength and functional capacity than seniors from the Fitness Zone.

OBJECTIVE: To assess the frailty level of elderly people with chronic kidney disease undergoing hemodialysis.METHODS: This is a cross-sectional study involving 60 participants and carried out at a Renal Replacement Therapy Unit. The Edmonton Frail Scale, translated and validated to Portuguese, was used as the instrument of research.RESULTS: Around 35.0% of the elderly showed no frailty, 26.7% were vulnerable, 20.0% showed mild frailty, 13.3% moderate frailty and 5.0% severe frailty.CONCLUSION: The frailty level of elderly people with chronic kidney disease undergoing hemodialysis was high and the number of elderly people who are vulnerable to frailty was also high.

Abductor Strength

Background Because people with total knee arthroplasty (TKA) have persistent functional limitations and disability, identifying modifiable risk factors for persistent disability is warranted. Before surgery, people have pervasive lower extremity muscle weakness. The fact that hip abductor muscle strength is often not targeted in postoperative rehabilitation may contribute to functional limitations. Objective Study objectives were: (1) to examine the reliability of handheld dynamometry (HHD) for measuring hip abductor strength and (2) to determine whether hip abductor strength contributes to physical function beyond the contribution of quadriceps muscle strength. Design This was a cross-sectional study. Methods Two-hundred ten participants underwent quadriceps and hip abductor muscle strength testing and measurement of physical function (performance-based and self-reported outcomes). Correlation and regression equations were built to determine the relationships of strength, pain, and functional ability. A subset of 16 participants underwent hip abductor strength testing at 2 sessions to determine the reliability of the measure. Results Measuring hip abductor strength with HHD yielded excellent relative reliability, with an intraclass correlation coefficient (ICC [2,3]) of .95 and a 95% confidence interval of .86 to .98, but moderate absolute reliability, with a minimal detectable change (with 95% confidence) of 47.6 N and a 95% confidence interval of 35.5 to 76.5. Hip abductor strength made a significant additional contribution to performance-based measures of physical function after anthropometric covariates and quadriceps muscle strength were accounted for. Hip abductor strength did not show bivariate correlations with patient-reported measures of physical function and did not contribute to patient-reported physical function after covariates and quadriceps muscle strength were accounted for. Limitations A cause-and-effect relationship between hip abductor strength and physical function could not be established. Conclusions In people with unilateral TKA, HHD testing of hip abductor strength is reliable. Hip abductor strength contributes to performance-based but not patient-reported measures of physical function in people with unilateral TKA.

ObjectivesThis study was aimed to assess the willingness of elderly people to seek medical care for tuberculosis (TB) and the associated influencing factors.DesignA cross-sectional study.SettingA multistage random survey was conducted in Bao’an District of Shenzhen in China.ParticipantsA total of 1200 elderly people aged 65 or above were recruited for the study and completed a structured questionnaire between September and October 2019.Main outcome measuresDescriptive and binary logistic stepwise regression analyses were conducted to analyse the characteristics of elderly individuals, their willingness to seek medical care for TB and associated factors.ResultsAmong the final 1123 respondents, 943 (84.0%) were willing to seek medical care if they discovered suspicious TB symptoms. Binary logistic stepwise regression analysis indicated that respondents whose family annual income per capita was 50 000–100 000¥ (OR=2.56, 95% CI: 1.44 to 4.54, p<0.01) and who had positive attitudes (≥3 scores: OR=3.10, 95% CI: 1.90 to 5.05, p<0.01) or practices (≥4 scores: OR=3.13, 95% CI: 1.82 to 5.39, p<0.01) towards TB were more willing to seek medical care for TB.ConclusionsWillingness to seek medical care for TB in the elderly population can be improved according to the determinants.
