Factors that impact functional performance of elderly with low back pain

<div><p>Abstract Introduction: Low back pain is a common condition among older adults and an important cause of disability. Objective: To evaluate the relationship between functional performance of older adults with low back pain and the following variables: sociodemographic and clinical factors, self-perceived health and back pain beliefs. Methods: A cross-sectional study that used data from the Back Complaints in the Elders international consortium. Information about sociodemographic factors (sex, age, marital status, formal education), clinical factors (intensity and frequency of pain, comorbidities), self-perceived health, back pain beliefs and functional performance (measured by the disability component of the Late Life Function and Disability Instrument - LLFDI) were collected through self-report. 191 older adults above 60 years with a new episode of back complaints who did not have any cognitive disorder, visual or hearing impairment, or motor disabilities participated in the study. A bivariate analysis was conducted between each independent variable and each outcome. Associations with p < 0.20 were selected for the multiple linear regression analysis, which was carried out for each LLFDI domain. Results: The multiple regression coefficients of determination were significant despite the modest magnitude. The variables related to functional performance were back beliefs, self-perceived health, formal education, pain frequency and marital status. Conclusion: These results may contribute to the expansion of health professionals’ work in the therapeutic approach of low back pain, broadening its focus beyond clinical aspects in order to value beliefs of older adults and their self-perceived health.</p></div

Effect of a resistance exercise program for sarcopenic elderly women: quasi-experimental study

<div><p>Abstract Introduction: Resistance training is quoted as one of the best pathways to manage sarcopenia and progressive resistance training is supposed to improve muscle mass, strength and performance in older adults. Objective: The aim was to examine the impact of a progressive resistance exercise program (PREP) on muscle and function performance in sarcopenic community-dwelling elder women. Methods: Quasi-experimental study (pre - post intervention). Participated 18 sarcopenic community-dwelling elder women (65 years or older). PREP based on 75% of the participant’s maximum load (12/wk, 3 times/wk). Main outcome measures: muscle strength of knee extensors (isokinetic dynamometry), muscle mass (dual-x ray absorptiometry - DXA), functional performance (Short Physical Performance Battery - SPPB). Paired t-test was used to evaluate differences pre and post intervention. Results: Improvements on power (p = 0.01) and peak torque (p = 0.01) were observed when measured by the isokinetic dynamometer at low speed (60º/s). Improvements on DXA (pre PREP: 5.49 kg/m2 vs. post PREP: 6.01 kg/m2; p = 0.03) and SPPB scores (pre PREP: 9.06 vs. post PREP: 10.28; p = 0.01) were also observed. Conclusion: The PREP was able to improve muscle and functional performance in sarcopenic community-dwelling elder women. This program should be considered in clinical practice.</p></div
