To define the effects of therapeutic exercise on bone density and back complaints.
A randomised controlled trial with parallel groups was conducted in an outpatient clinic, Medical School, University of Vienna. Ninety two sedentary post-menopausal women with back problems were randomly allocated to either exercise (groups 1 and 2) or control (group 3, no exercise, n = 31); the exercise group was retrospectively subdivided into compliant (group 1, n = 27) and not fully compliant patients (group 2, n = 34). Regular, initially supervised therapeutic exercise aimed at restoring biomechanical function was performed for four years. Bone density in the forearm was measured by single photon absorptiometry at entry and after four years; subjective back complaints were documented.
A significant decrease in bone density was observed in groups 2 and 3; no change was noted in group 1; back complaints decreased in group 1 only.
Sedentary postmenopausal women may benefit from regular long term therapeutic exercise in terms of subjective back complaints and slowed loss of bone mass.
确定治疗性锻炼对骨密度和背部不适的影响。
在维也纳大学医学院门诊部进行了一项平行组随机对照试验。92名有背部问题的久坐绝经后妇女被随机分配到锻炼组（第1组和第2组）或对照组（第3组，不锻炼，n = 31）；锻炼组事后被细分为依从组（第1组，n = 27）和不完全依从组（第2组，n = 34）。进行了为期四年的有规律的、最初有监督的旨在恢复生物力学功能的治疗性锻炼。在入组时和四年后通过单光子吸收法测量前臂骨密度；记录主观背部不适情况。
第2组和第3组观察到骨密度显著下降；第1组未发现变化；仅第1组的背部不适有所减轻。
久坐的绝经后妇女在主观背部不适和减缓骨质流失方面可能从长期规律的治疗性锻炼中获益。
