摘要和关键词

摘要: 当人体在动态干扰下足底与支撑面不完全接触时, 可以寻找并求解一个有效指标作为动态平衡研究方法。文章根据足底三分区理论研制出一套足底分区测力平台, 设计对应的扰动装置实现测力平台在竖直方向上的移动干扰; 在整个扰动平衡过程中提出干扰起始时刻(time of the start of disturbing, TSD), 并基于TSD提出调整起始时刻(time of the start of adjustment, TSA)和调整结束时刻(time of the end of adjustment, TEA); 将TSA至TEA阶段内的姿势稳定程度与完整支撑面静止站立和部分支撑面静止站立阶段内的相比较, 验证TSA和TEA的合理性, 并将TSD与TSA之间的时间定义为反应时间(time of reaction, TR)。对10名健康志愿者进行足底扰动的人体平衡能力试验, 通过测力平台得到平均反应时间, 并对该反应时间进行有效的可靠性分析。结果表明, 求解反应时间的方法可以作为研究足底支撑面扰动平衡的有效方法。

Abstract and Keywords

Abstract: To study the dynamic balance of the human body when the sole of the foot does not fully contact the support surface under dynamic interference, identifying and solving an effective index can serve as a research method. This paper developed a zonal plantar force measurement platform based on the theory of three zones of the foot, and designed corresponding disturbance devices to achieve vertical movement interference of the force measurement platform. During the entire disturbance balance process, time of the start of disturbing (TSD) was proposed, and time of the start of adjustment (TSA) and time of the end of adjustment (TEA) were proposed based on TSD. The stability of posture during the TSA and TEA stages was compared with that during the stages of standing still with whole support surface (SSWSS) and standing still with partial support surface (SSPSS) to verify the rationality of TSA and TEA. The time between TSD and TSA was taken as the time of reaction (TR). A plantar disturbance balance experiment was conducted on ten healthy volunteers, and the average TR was obtained through the force measurement platform. The effectiveness and reliability of the obtained TR were analyzed. The results show that the method of solving TR can be used as an effective method for studying the balance of plantar support surface disturbance.

Keywords: balance assessment; plantar partition; plantar force measurement; disturbance; time of reaction(TR)
