自适应式平衡调整模块探讨     

杨桂芳 《淮南职业技术学院学报》2007,7(4):93-96

模块在机构上继承了在静态步态中使用的结构,并在此基础上加入了一套独立设计的平衡调整模块,设计了自适应式动态步态模块,对模块的进行了探讨,对步行机器人实现仿人的步行方式具有意义。  相似文献   

膝关节损伤患者的步态分析     

邹亮畴  马晋 《广州体育学院学报》1999,(3)

对一名右膝肌肉轻微损伤的大学生运动员治疗与康复训练前后的步态进行运动学与动力学分析,结果表明,康复前损伤倒肌力下降,运动能力降低,两侧的运动学与动力学参数呈不对称状态,康复后步长,步频与步速明显增加,支撑及双支撑时间及比例减少,地面支撑反作用力曲线相对起伏较小,两侧运动学与动力学指标具有对称的特点。  相似文献

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.  相似文献   

Test–retest reliability of the Tekscan® F-Scan® 7 in-shoe plantar pressure system during treadmill walking in healthy recreationally active individuals     

Kyle Patrick 《Sports biomechanics / International Society of Biomechanics in Sports》2018,17(1):83-97

In-shoe plantar pressure systems are commonly used in clinical and research settings to assess foot function during functional tasks. Recently, Tekscan® has updated their F-Scan® in-shoe plantar pressure system; however, this system’s test–retest reliability has not been established. Therefore, the purpose of this study was to determine the test–retest reliability of the F-Scan® 7 system in recreationally active individuals during treadmill walking. Seventeen healthy adults completed 2 sessions of treadmill walking. For each session, participants were fitted for shoes and pressure insoles and walked on a treadmill at a self-selected pace for 30 s. Following the sessions, the test–retest reliability peak pressure, pressure time integral, average pressure and pressure contact area over 4 regions of the foot (heel, mid-foot, forefoot and toes) was assessed by calculating intraclass coefficients (ICC 2,k) and coefficient of variation percentage (CoV%). Pressure contact area consistently had the highest ICCs and lowest CoV% (ICCs: 0.91–0.98; CoV%: 2.7–7.8%). Whereas, the forefoot and toe regions had the highest ICCs for all 4 measures (ICCs: 0.83–0.98; CoV%: 3.1–13.4%). During treadmill walking in healthy recreationally active individuals, the reliability of the new Tekscan F-Scan® ranged from poor to high and was dependent on the measure and region of the foot.  相似文献
