| 摘 要： | 目的:观察3个月综合锻炼对社区老年人步态的影响.方法:研究对象为自愿参加本次测试的控江社区60～80岁老年女性16名.志愿者参加每周3次、每次1.5小时、为期3个月的针对性综合锻炼干预,步态指标由VICON系统与KISTLER测力台进行数据同步采集,并使用VISUAL3D软件进行分析.结果:经过运动干预后,志愿者步态指标发生显著变化,表现为步长增加(0.54 ±0.07m VS 0.60±0.06 m,P＜0.01)、步速加快(1.10±0.18 VS1.29±0.22 m/s,P＜0.01)、双支撑时相缩短(24.10％±5.10％ VS 21.08％±3.99％,P＜0.01)、步态各周期中髋、膝、踝关节活动幅显著加大.结论:简易的综合性锻炼计划对老年人步态有显著的改善效果,建议可作为预防老年人跌倒的运动干预手段.

| Abstract: | The purpose of this study was to determine the effects of a 3-month combined exercise intervention on gait in community-dwelling elderly women.Methods Sixteen participants(60~80 years old) attended for 1.5-hour combined exercise sessions three times a week for three months.Gait parameters data were collected using a 3D motional analysis system(Vicon system) and a force platform(Kistler),and analysed using the VISUAL3D software.Results Results showed that after 3 months of combined exercise,the stride length(0.54±0.07VS0.60±0.06 m,P<0.01)and velocity(1.10±0.18VS1.29±0.22 m/s,P<0.01) increased significantly,while the amount of time spent in the double support phase decreased significantly(24.10%±5.10%VS21.08%±3.99%,P<0.01).Hip and ankle dynamic range of motion(ROM) increased significantly(P<0.05) after exercise intervention.The ankle plantar-flexion joint angle at the phase of heel-contact decreased significantly(P<0.05),while the joint angle of knee flexion and ankle dorsi-flexion at the phase of mid-swing increased significantly(P<0.05) following exercise intervention.The results suggest that the 3-month combined exercise intervention program could be an effective approach to reduce the risk factors for falls in community-dwelling elderly people by modifying their gait. |
