RESUMO
@#Objective To observe the effect of progressive resistance exercise combined with alendronate sodium on bone mineral density(BMD)of lumbar spine in patients with postmenopausal osteoporosis.Methods 20 patients with postmenopausal osteoporosis were randomly divided into the A and B group with 10 cases in each group.The cases of the group A were treated with progressive resistance exercises combined with alendronate sodium.Those of the group B only took alendronate sodium orally.The course of two groups was 3 months.BMD of lumbar spine was measured by dual-energy X-ray absorptiometry before and 3 months after treatment.Results Before treatment,BMD of two groups was not different.After 3 months treatment,BMD of lumbar spine were significantly improved in group A(raised 4.520±0.68%)than group B(raised 0.100±0.01%),there was a significant difference between two groups(P<0.01).Conclusion Progressive resistance exercises combined with alendronate is more efficacious than alendronate alone in restoring lumbar spine BMD in patients with postmenopausal osteoporosis.
