一种基于人体骨盆中心的静态平衡能力评价方法

Evaluation Method of Static Balance Ability Based on Human Pelvic Center Measurement

该研究基于下肢康复机器人对人体静态平衡能力进行评估。对下肢功能正常者和下肢功能障碍者进行平衡对照实验,根据人体骨盆中心运动轨迹得到的平衡参数,用SPSS统计软件验证两组间具有显著性差异(P<0.01)。运用主成分分析法对各参数权重分配,建立综合评价值。对照组综合评价值为0.383±0.038,实验组综合评价值为0.875±0.136。当受试者综合评价值在0.739~1.011范围内时,说明存在平衡功能障碍,在0.345~0.421范围内时,则说明受试者下肢平衡正常。实验证明,该评价方法能够客观定量地反映人体静态平衡状态。

This study evaluates the static balance ability of human body based on lower limb rehabilitation robot.According to the balance parameters obtained from the movement trajectory of the center of human pelvis,SPSS statistical software was used to verify that there was significant difference between the two groups(P<0.01).Principal component analysis is used to allocate the weight of each parameter and establish the comprehensive evaluation value.The comprehensive evaluation value of the control group was 0.383±0.038,and the experimental group was 0.875±0.136.When the subject’s comprehensive evaluation value is between 0.739 and 1.011,it indicates the presence of balance dysfunction,and when it is between 0.345~0.421,it indicates that the balance of the lower limbs of the subject is normal.Experimental results show that this evaluation method can objectively and quantitatively reflect the static equilibrium state of human body.
