全身振动对绝经后妇女平衡能力的影响

The effects of whole body vibration on balance ability in postmenopausal women

目的:通过对绝经后妇女进行16周的振动训练,研究振动刺激对绝经后妇女平衡能力的影响。方法:21例50—63岁绝经后妇女随机分为实验组和对照组,采用Postural Equa平衡分析系统测量平衡能力等各项指标。实验组采用振动干预,对照组不接受任何干预。振动方案为:频率30—45Hz、20min/次,3次/周,连续16周。结果:组内对比,实验组在实验后,在闭眼状态下,压力中心(COP)指标中的Y值、最大摆幅(ML)值、线形图面积(AREA)值都明显低于实验前,分别下降7.33mm、8.33mm、16.67mm(P<0.05);在睁眼状态下,其他各指标差异不明显。组间对比,实验组与对照组在实验前后,在睁眼和闭眼状态下静态平衡指标COP、TL、ML和AREA也未见有明显改变(P>0.05)。结论:16周的全身振动训练方案可以明显改善绝经期妇女的静态平衡功能。

Objective： To investigate the effects of vibration stimulation on balance ability in postmenopausal women. Method： Twenty-one postmenopausal women were randomized to either vibration group or control group. Balance ability were measured. The vibration group consisted of a 16 weeks vibration training（30-45Hz, lOmin, 3 times per week）. Result： In vibration group after experiment when the subjects closed eyes static central of pressure（COP） Y, maximal length of swinging pathway （ML） and Area of swinging pathway（AREA） reduced significantly （P〈0.05）. But no significant changes of other indices of balance were observed between both groups. Conclusion： Sixteen week vibration training can improve postmenopausal women＇s static balance ability.
