| 目的探讨胸椎过度后凸老年女性患者竖脊肌抗疲劳能力，以及肺功能、日常生活活动能力的特征。方法选取112例老年女性，其中胸椎过度后凸者56例为观察组，不伴胸椎过度后凸者56例为对照组。采集两组患者竖脊肌表面肌电信号，采用频域指标中位频率的斜率（MFs）评估竖脊肌抗疲劳能力，同时测量并比较两组患者胸椎后凸Cobb角、肺活量，并进行6min步行试验比较6min步行距离（6MWT）。结果观察组患者胸椎后凸Cobb角大于对照组（P＜0.05），肺活量、6MWT均小于对照组（均P＜0.05），竖脊肌|MFs|大于对照组（P＜0.05）。观察组患者竖脊肌|MFs|与胸椎后凸Cobb角呈正相关（r=0.879，P＜0.05），即观察组患者竖脊肌抗疲劳能力与胸椎后凸Cobb角成负相关。结论胸椎过度后凸老年女性患者竖脊肌抗疲劳能力明显下降，肺活量、日常生活活动能力亦明显下降。 |

| Abstract: |
| Objective To observe the characteristics of spinal erectors and physical capacities in elderly women with hyperkyphosis. Methods Fifty-six women (aged 63-85 years) with hyperkyphosis were recruited in the study(study group) and 56 women (aged 65 －83 years) without hyperkyphosis served as control group. The anti-fatigue ability of spinal erectors was measured by slope of median frequency (MFs) on surface electromyograph (sEMG), the thoracic kyphosis Cobb angle and vital capacity were measured and six-minute walk test (6MWT) was performed in two groups. Results Study group had greater Cobb angle and |MFs| than control group (P＜0.05), while the vital capacity and the distance of 6MWT were reduced significantly in study group compared with control group (P＜0.05). There was significant positive correlation between |MFs| and Cobb angle
(r=0.879, P＜0.05) in study group. Conclusion Anti-fatigue ability of spinal erectors, vital capacity and activities of daily living are significantly decreased in elderly women with hyperkyphosis. |
