脑卒中偏瘫患者康复治疗前后的三维步态分析

目的分析脑卒中偏瘫患者康复治疗前后的三维步态特点。方法采用三维步态分析仪对28 例脑卒中偏瘫患者6 周的常规康复训练前后分别进行三维步态分析检查。结果治疗后患侧下肢站立相百分比较前增加(P<0.05)，摆动相百分比较前减少(P<0.05)，较前接近正常值；患侧下肢的步长、跨步长，步速均较前增加(P<0.05)；患者髋关节内收外展、屈曲伸展，膝关节屈曲伸展，踝关节内外旋转、内翻外翻、背屈跖屈均较前改善(P<0.05)。结论三维步态分析系统能定量地评价患者的步态情况，可作为康复疗效评定的指标之一。

3D Gait Analysis of Stroke Hemiplegic Patients before and after Rehabilitation

Objective To explore the 3D gait analysis of stroke hemiplegic patients. Methods 28 stroke hemiplegic patients were examined with the 3D gait analysis system before and after 6-week rehabilitation. Results After rehabilitation, support phase time of the affected lower limb increased and swing phase time decreased (P<0.05). Step length, stride length and walking speed increased (P<0.05). There was significantly difference in range of motion (ROM) of hip deduction/abduction, flexion/extension, and knee flexion/extension, and ankle internal/external rotation, varus/eversion, dorsiflexion/plantar flexion before and after rehabilitation (P<0.05). Conclusion 3D gait analysis system can evaluate the patient's gait objectively and quantitatively, and provide the basis for rehabilitation assessment.
