Efficacy of home-based exercise for improving quality of life among elderly women with symptomatic osteoporosis-related vertebral fractures

Abstract

This randomized controlled trial was designed to investigate the effect of a 6-month home-based exercise program versus control (usual activities) on quality of life for postmenopausal women with osteoporosis who had at least one vertebral fracture. Twelve-month assessments of outcomes were completed to determine if women would continue exercising with minimal supervision and if benefit could be sustained. The home exercise program followed a "lifestyle exercise" approach where participants completed exercises 60 min per day, 3 days a week and could complete exercises in small periods of time throughout the day. Exercise activities included stretching, strength training and aerobics (i.e. walking). Participants were assessed at baseline, 6 months, and 12 months using the Osteoporosis Quality of Life Questionnaire (OQLQ), the Sickness Impact Profile (SIP), a balance test, and the Timed Up And Go test. Bone mineral density was assessed at baseline and 12 months for both the lumbar spine and femoral neck. Quality of life (OQLQ) improved over 6 months in the exercise group compared to the control group in the domains of symptoms (P=0.003), emotion (P=0.01) and leisure (P=0.03). Results from the balance test indicated a greater effect in the exercise group over 12 months (P<0.05). There were no significant differences between groups in measures of Timed Up and Go, SIP at 6 and 12 months, and femoral neck and lumbar spine bone mineral density at 12 months. Home-based exercise with minimal supervision improves quality of life in elderly women with vertebral fractures. Future research is needed to determine if home exercise programs reduce falls and fall-related injuries in the elderly.
