摘　　要：目的研究临床应用较广的低频脉冲电磁场(PEMFs)对于绝经后骨质疏松症患者的平衡功能是否有影响。方法参照国际临床试验常用分组方法,将符合标准的43例患者进行分组,其中试验组24例,对照组19例。在均给予常规药物治疗基础上,对试验组患者加用PEMFs治疗,采用1次/d、40min/次、共30次的治疗周期。治疗前后分别对患者进行广泛应用的Berg平衡量表(BBS)、限时站起和行走测试(TUG)、平衡测定仪检测。结果经30次治疗后,试验组BBS评分增高,TUG评分、前后摆幅指数、矩形面积和轨迹长降低(P<0.05),而对照组仅BBS评分增高,轨迹长降低(P<0.05)。组间比较,试验组前后摆幅指数的降低较对照组明显(P<0.01)。结论PEMFs治疗能在一定程度上改善绝经后骨质疏松症患者的平衡功能。Objective To assess the effect of pulsed electromagnetic fields （PEMFs）on balance ability of postmenopausal women with osteoporosis. Methods 43 eligible patients were randomly divided into experimental （n=24） and control （n = 19） groups. Patients in both groups received conventional drug therapy. Meanwhile, patients in the experimental group were given PEMFs once a day for 30 days. Results The Berg Balance Scale （BBS） scores increased and the timed upand to test （TUG） scores, sway index （forward-backward）, rectangle area and sway path decreased in the patients in the experimental group （P〈0.05）. In the patients in the control group, only changes in BBS scores and sway path were statistically significant （P〈0.05）. The decrease of sway index （forward-backward） in the experimental group was greater than that of the control group （P〈0.01）. Conclusion PEMFs can improve the balance ability of patients with post-menopausal osteoporosis.
