Abstract

There is little evidence that home-based muscle training through exercise improves the muscle strength and QoL of elderly osteoporotic women. The efficacy of home-based daily exercise on muscle strength of the upper and lower extremities and QoL were examined in elderly osteoporotic women by means of a case-controlled study that was designed and conducted between 2005 and 2006. Sixty-three osteoporotic women over 60 years of age were randomly assigned to 12 months of muscle exercise or to no intervention. The outcomes were changes in muscle strength and quality of life (QoL). Ultimately, sixty-two participants completed the 12 months program. Before the start of home-exercise training, the lumbar spine bone mineral density (BMD) and femoral neck BMD values in the intervention group were significantly lower than those in the control group (p<0.05). Grip strength and maximum walking speed increased significantly in the intervention group (p<0.05). In terms of QoL, physical functioning was improved by home-based exercise in the intervention group (p=0.05), while there were no improvements in any of the categories of Short-Form 36 in the control group. Our results suggest that home-based training is effective for elderly osteoporotic women in improving not only muscle strength in upper and lower extremities but also physical functioning in QoL.
