Abstract
Introduction: The proportion of older adults in the population continues to grow in the developing countries. In addition, persons at or over the age of 60 years have decreased quality of life in geriartrics because of several factors, such as low physical activity and impairment in mobility. This study was performed to assess the effect of group-based exercise program on physical functional independency in order to finally increase the quality of life in older adults.
Methods: This quasi-experimental study was conducted in old women and men in 2005-2007. In this study, 50 elderly men and women were randomly divided into two groups experimental (25) and control (25).Group-based exercise program was administrated to the individuals of experimental group for 8 weeks (3 time a week) and subsequently using SF-36 questionnaire, the level of quality of life was measured in the two groups at the beginning and the end of the study. The data was analyzed using manvitni , chi-square and nonparametric tests.
Results: Using group-based exercise program, increase in mean level of quality of life in different dimensions physical functional, role functional, pain, general health, emotional well-being, social functional , emotional functional and mental health was statistically significant(p<0.01),whereas in the control group ,these parameters, were unchanged(p>0.01).
Conclusion: Our study results showed that use of a regular and prolonged exercise program can increase the level of quality of life in older adults in different dimensions.

Abstract
Introduction: As a person gets older, their gait patterns change and their ability to walk decreases. Orthoses are used to relieve musculoskeletal disorders, skeletal problems, disabilities, etc. Therefore, the aim of this study was to investigate the effect of orthoses on timing of lower limb muscles in the older adults during gait.
Methods: The present study was a clinical trial. 14 females (with average age of 60.50±4.40 years) and 14 males (with average age of 63.35±5.55 years) were selected with available sampling, voluntarily participated in this research. Eight electrodes were placed on the selected muscles (tibialis anterior, gastrocnemius medial, vastus medialis, vastus lateralis, biceps femoris, semitendinosus, gluteus medius, erector spinae) to record electrical activity during the gait with and without orthoses. To analyze the data SPSS software (version 16), and a repeated analysis of variance test was used. The significance levels in all tests were considered to be 0.05.
Results: The main effects of orthoses and the interaction effects of orthoses and sex for the onset of selected muscles activities did not show any significant differences (P>0.05). The effect of sex for the onset of activities in medial gastrocnemius (P=0.007), vastus medialis (P=0.002), vastus lateralis (P=0.027), semitendinosus (P=0.004), gluteus medius (P=0.030), and erector spinae (P=0.039) muscles was significant, so that the onset of muscle activity in the female group was earlier than in the male group.
Conclusion: Orthoses showed no improvement on onset of selected muscles activities, although significant differences were observed between the male and female groups.
