Effect of low-intensity back exercise on quality of life and back extensor strength in patients with osteoporosis : a randomized controlled trial . UNLABELLED Randomized controlled study in 80 postmenopausal women with osteoporosis was conducted to investigate the effect of a home-based , simple , low-intensity exercise . Low-intensity back-strengthening exercise was effective in improving the quality of life and back extensor strength . INTRODUCTION AND HYPOTHESIS Back-strengthening exercise is effective in increasing back extensor strength and decreasing risk of vertebral fractures . We hypothesized that a home-based , simple , low-intensity exercise could enhance back extensor strength and improve the quality of life and/or spinal range of motion in postmenopausal women in a short-term follow-up . METHODS Eighty postmenopausal women with osteoporosis were randomly assigned to a control group ( n = 38 ) or an exercise group ( n = 42 ) . Subjects were instructed to lift their upper trunk from a prone position antigravity and maintain the neutral position . Isometric back extensor strength , spinal range of motion , and scores for quality of life were evaluated at baseline and 4 months . RESULTS Back extensor strength significantly increased both in the exercise group ( 26 % ) and in the control group ( 11 % ) . Scores for quality of life increased in the exercise group ( 7 % ) , whereas it remained unchanged in the control group ( 0 % ) . There was a significant difference in quality of life score between the groups ( p = 0.012 ) . CONCLUSIONS Low-intensity back-strengthening exercise was effective in improving the quality of life and back extensor strength in patients with osteoporosis .
