摘　　要：目的分析脑卒中偏瘫患者足底压力与步行时相的相关性。方法选取可以安全独立步行10 m以上的脑卒中偏瘫患者30例作为实验组,正常成人30例作为对照组,采用步态与平衡功能训练评估系统对受试者进行步态时空参数及足底压力的检测与分析。结果正常成人两侧足底压力峰值比较差异无统计学意义(P>0.05)。脑卒中偏瘫患者两侧压力峰值比较差异有统计学意义(P<0.01)。实验组与对照组的足底压力峰值、摆动相时间比、支撑相时间比比较差异有统计学意义(P<0.05)。脑卒中偏瘫患者健侧下肢足跟着地期、支撑期及蹬离期足底压力峰值与摆动相时间比均呈正相关(r=0.901、0.728、0.866;P<0.01),与支撑相时间比均呈正相关(r=0.823、0.624、0.698;P<0.01)。脑卒中偏瘫患者患侧下肢足跟着地期、支撑期及蹬离期足底压力峰值与摆动相时间比均呈负相关(r=-0.841、-0.774、-0.832;P<0.01),与支撑相时间比均呈负相关(r=-0.875、-0.637、-0.815;P<0.01)。结论脑卒中偏瘫患者足底压力峰值与步行时相密切相关。Objective To analyze the patients. Methods Thirty post-stroke correlation of plantar pressure and walking phase in post-stroke hemiplegic hemiplegic patients were recruited for the experimental group. These patients were accorded with the criteria that the subjects could walk 10 m independently. Thirty healthy adults were selected as control group. Gait and balance function training evaluation system was used in time-space parameter and plantar pressure analysis. Results There was no significant difference （P 〉 0. 05 ） in the peak of plantar pressure of left and right lower limbs of normal persons. There were significant differences （P 〈 0.01 ） in the peak of plantar pres- sure of affected and unaffected lower limbs of post-stroke hemiplegic patients. Compared to the control group, there were significant differences （P 〈 0. 05 ） in the peak of plantar pressure, swing time ratio and stance time ratio of post-stroke hemiplegic patients. The swing time ratio and stance time ratio of post-stroke hemiplegic patients had a positive correlation with the peak of plantar pressure of unaffected lower limbs post-stroke hemiplegic patients in heel strike phase, stance phase and push-off phase （P 〈 0. 01 ）. The swing time ratio and stance time ratio of post- stroke hemiplegic patients had a negative correlation with the peak of plantar pressure of affected lower limbs post- stroke hemiplegic patients in heel strike phase, stance phase and push-off phase （P 〈 0. 01 ）. Conclusion Plantar pressure of unaffected and affected lower limbs post-stroke hemiplegic patients has a high correlation with walking phase.
