目的探讨绝经后健康女性的稳定极限范围(LOS)与育龄期健康成年女性相比有无下降,了解绝经后女性是否开始出现LOS的下降。方法选取2012年1月-10月期间于四川大学华西医院健康体检的女性共40例,绝经组:20例绝经后健康女性,年龄(56.2±3.3)岁;对照组:20名育龄期健康女性,年龄(24.3±3.5)岁。对所有受试者分别使用压力平板仪测定前后左右4个方向LOS,使用SPSS 17.0统计学软件比较两组LOS的差异性。结果前、后、左、右4个方向的LOS在绝经组与对照组之间差异无统计学意义(P>0.05)。绝经组及对照组的左右侧LOS大于前后侧、前侧LOS大于后侧,差异具有统计学意义(P<0.05);左右侧LOS差异无统计学意义(P>0.05)。结论绝经后女性仍保持较好的LOS,提示其仍具备良好的主动姿势控制能力。
Objective To investigate whether the stability limit (LOS) of healthy women with postmenopausal women is lower than healthy adult women of childbearing age and whether the decline of LOS begins to occur in postmenopausal women. Methods Forty women with physical examination at West China Hospital of Sichuan University from January to October 2012 were enrolled in the study. Menopause group consisted of 20 healthy postmenopausal women aged 56.2 ± 3.3 years and 20 healthy women of childbearing age , Age (24.3 ± 3.5) years old. All subjects were measured using pressure plate before and after 4 directions LOS, using SPSS 17.0 statistical software to compare the differences between the two groups of LOS. Results There was no significant difference of LOS in the four directions before, after, left and right between the menopausal group and the control group (P> 0.05). The left and right LOS of the menopause group and the control group were larger than anterior and posterior sides, while the anterior LOS was larger than the posterior side (P <0.05). There was no significant difference in left and right LOS (P> 0.05). Conclusion Postmenopausal women still maintain a good LOS, suggesting that they still have a good ability to control their posture.
