【摘要】：目的:探讨脑卒中偏瘫患者步行时足底压力中心(COP)时空参数的不对称性及其与步速的相关性。方法:选取能够独立步行的脑卒中偏瘫患者(偏瘫组)及健康中老年人(正常组)各30例,每组受试者均以自然步速进行步态测试,提取并计算步速、单支撑时间、双支撑时间、单支撑期COP在前后方向的位移(AP-COPDS)及速度(AP-COPVS)、双支撑期COP在前后方向的位移(AP-COPDD)及速度(AP-COPVD),计算COP时空参数的对称性比,组内进行两侧下肢COP时空参数比较,组间进行COP时空参数对称性比比较,并分析偏瘫组各步态参数对称性比与步速的相关程度。结果:与健侧相比,患侧单支撑时间、AP-COPDS、AP-COPVS减小,AP-COPDD增加,差异均有显著性意义(P0.05)。与正常组相比,偏瘫组单支撑时间、AP-COPDS、AP-COPVS三者的对称性比均减小,AP-COPDD对称性比增大,差异均有显著性意义(P0.05)。偏瘫组步速与单支撑时间对称性比呈高度正相关(r=0.76,P0.05),与APCOPDS、AP-COPVS两者的对称性比呈中度正相关(r=0.682,r=0.442,P0.05),与AP-COPVD对称性比存在负相关趋势(r=-0.363,P=0.053)。结论:脑卒中偏瘫患者步行时COP时空参数呈不对称性模式,且其不对称性与步速存在相关性。
[Abstract]:Objective: to investigate the asymmetry of space-time parameters of plantar pressure center during walking in stroke patients with hemiplegia and its correlation with walking speed. Methods: to select stroke hemiplegic patients (hemiplegia group) and healthy elderly people who can walk independently. There were 30 cases in the normal group and 30 cases in the normal group. In each group, the gait test was carried out at natural walking speed, and the walking speed, single support time and double support time were extracted and calculated. The displacement (AP-COPDS) and velocity (AP-COPVS) of COP in the front and back direction of single bracing period, the displacement of COP (AP-COPDD) and the velocity of AP-COPVD in the back and back direction of double bracing period were calculated. The symmetry ratio of COP space-time parameters was calculated, and the space-time parameters of lower extremity COP in both sides of the group were compared. The ratio of space-time parameter symmetry of COP was compared between the two groups, and the correlation between the symmetry ratio of each gait parameter and the walking speed was analyzed. Results: compared with the healthy side, the AP-COPDSS-AP-COPVS decreased the AP-COPDD increase. Compared with the normal group, the symmetry ratio of AP-COPDSS-AP-COPVS in the hemiplegia group decreased and the AP-COPDD symmetry ratio increased. There were significant differences between the two groups (P 0.05). There was a high positive correlation between the symmetry ratio of walking speed and single support time in hemiplegia group, and a high positive correlation between the symmetry ratio of AP-COPVS and APCOPDS AP-COPVS, and a moderate positive correlation between the symmetry ratio of AP-COPVS and APCOPDS-0.682OP-COPVS, and a negative correlation with the symmetry ratio of AP-COPVD. Conclusion: there is a negative correlation with the symmetry ratio of AP-COPVD. Conclusion: the hemiplegia in stroke patients with hemiplegia has a tendency of negative correlation. The spatiotemporal parameters of COP were asymmetrical during walking. There is a correlation between the asymmetry and the step speed.
