【摘要】：应用footscan汶足底压力测量系统,对32例健康女大学生被试在步行和慢跑时足底压力中心(centre of pressure,COP)轨迹的变化规律进行不同运动模式下的对照研究,分别分析左足、右足在5次步行或慢跑时整个支撑期的COP轨迹及其相似度。结果表明:1)不同运动模式(步行与慢跑)的COP轨迹相似度低于0.25;2)同一运动模式(步行或慢跑)下,左侧、右侧的COP轨迹均具有很高的相似度(大于0.91)。其中被试内(同一被试)COP轨迹相似度高于被试间(不同被试),且前者方差低于后者,差值具有显著意义;被试内(同一被试)同侧足之间的COP轨迹相似度高于异侧足间,差值具有统计学意义。通过分析得到:步行和慢跑两个运动模式的COP轨迹相似度很低,COP轨迹可以识别不同的运动模式;运动模式相同时,不同被试间的COP轨迹相似度较高,且同一被试内同一侧的COP轨迹相似度更高。研究结果可以为临床诊断、康复评定、矫形处方和运动训练等提供参考依据。
[Abstract]:Footscan plantar pressure measurement system was used to study the changes of foot pressure center centre of pressure center during walking and jogging in 32 healthy female college students under different movement modes, and the left foot was analyzed respectively. The COP trajectory and similarity of the right foot during the entire support period after 5 walks or jogging. The results showed that the COP trajectory similarity of different exercise patterns (walking and jogging) was lower than that of 0.25g. Under the same exercise pattern (walking or jogging), the COP locus on the left and the right had high similarity (> 0.91). The similarity of cop locus in the same group was higher than that in the other group (different subjects, the variance of the former was lower than that of the latter, and the difference was significant, and the similarity of COP locus between the same side foot was higher than that between the other side foot and the other side foot. The difference is statistically significant. The results show that the COP trajectory similarity of walking and jogging patterns is very low and the cop trajectory can identify different motion patterns, and the COP trajectory similarity between different subjects is higher when the exercise pattern is the same. Moreover, the similarity of COP locus in the same side of the same subjects was higher. The results can provide reference for clinical diagnosis, rehabilitation evaluation, orthopedic prescription and exercise training.
