Determining the Effects of a 4-Week Structured Strength and Flexibility Exercise Program on Functional Status of Subjects with Osteoporosis.

backgroundOsteoporosis is a systemic disease resulting in low bone mineral density, increased risk of fractures, and falls, muscle weakness, and compromised balance. Nutrition and physical exercise have been shown to be effective in the treatment of low bone mineral density and, with more severe osteoporosis, as adjuncts to pharmaceutical treatments. However, living with osteoporosis may diminish an individual's ability and confidence to perform activities that enhance bone density. QUESTIONS/PURPOSES: This study investigated the following question: In women with osteoporosis, will there be a greater improvement in balance, lower-extremity strength, mobility, and confidence in performing ambulatory activities after participating in a structured exercise program as compared to a control group?

methodsThis was a prospective comparative trial in which 48 women who had a confirmed diagnosis of osteoporosis were enrolled in either an exercise group (a 4-week exercise program) or a control group (no structured exercise). Functional outcomes using valid and reliable tools were measured before and after exercise in the study group and at comparable times in the control group. Differences in function were assessed by paired

conclusionThis study showed that women with osteoporosis demonstrated improved balance and lower-extremity strength after participating in a structured exercise program. These changes may be important in improving overall functional status.
