Background: The decrease in muscle strength in older adults has an impact on functionality. Muscle strengthening programs have been proposed, however there is some controversy surrounding the effects of stretching prior to strengthening exercises on muscle strength gain. Objective: To verify the impact of static stretching on the gain in knee-extensor strength of community-dwelling elderly women after a training program. Methods: This was a quasi-experimental study that included a ten-week knee-extensor strengthening program and a final assessment of 12 community-dwelling elderly women divided into two groups: group SE - strengthening exercises with prior static stretching in all sessions, mean age 73.8 (±5.36) years; and group E - same strengthening exercises as SE without prior stretching, mean age 72.14 (±5.43) years. To measure knee-extensor strength gains, we used the isokinetic dynamometer Biodex System 3 Pro, in concentric mode at angular velocities of 60° and 1807s, and for statistical analysis we used the difference between pre- and post-intervention means of work adjusted by body weight. Results: The data showed normality in the Shapiro-Wilk test (p>0.266). When comparing the differences between the pre- and post-intervention means using the t test for independent samples, there was no significant difference in any of the limbs at the velocities evaluated (p>0.383). Conclusion: Previous static stretching did not interfere in muscle strength gain following a ten- week muscle strengthening program in the population studied. [ABSTRACT FROM AUTHOR]

Background: Pain is considered a multidimensional experience and is very common in the elderly. The pain locus of control has become essential to understand how the perceptions, expectations and beliefs are related to individual behavior, attitudes, coping and adherence of the elderly with regards to the health conditions and with the proposed treatment. Studies focused on adaptation and reliability of instruments are necessary for health professionals. Objectives: The present study performed the cross-cultural adaptation of the Pain Locus of Control Scale (C form of Multidimensional Health Locus of Control) for Brazil and assessed its intra and inter-examiner reliability among a sample of 68 elderly individuals with non-oncological pain living in the community. Methods: The cross-cultural adaptation of the scale was performed using the methodology standardized by Beaton et al. (2000)*. Pearson's correlation coefficient (PCC) and the intraclass correlation coefficient (ICC) were used for the statistical analysis (p.0.05). Results: Average age of the subjects was 69.6 ± 5.5 years; most were women, with low levels of income and education. The average pain duration was 10.2 years and the main clinical diagnosis was osteoarthritis. The reliability of the scale was adequate, with a regular to very strong correlations (PCC = 0.60 to 0.93) and a moderate to nearly perfect ICC (0.60 to 0.93), in mainly the chance locus of control and medical and healthcare professionals locus of control subscales. Conclusion: An adequate reliability and applicability was observed in our sample after adjustments and adaptations of the scale for use in elderly [ABSTRACT FROM AUTHOR]
