The kinematic characteristics of the knee hyperextension gait in stroke patients with hemiplegia
摘要
Abstract
Objective:Using three-dimensional gait analysis system to analyze the kinematic parameters and the correlation with walking speed,so as to explore the main kinematic factors influencing the walking speed of stroke patients with knee hyperextension.Methods:The kinematic parameters were compared between 15 stroke patients with knee hyperextension and 15 healthy elderly people,and the correlation between walking speed and kinematic parameters was analyzed.Results:Compared to the healthy elderly people,step length,stride frequency and walk-ing speed in the stroke patients were significantly reduced,but the supporting period percentage was increased(P<0.05).The joint range of motion(ROM)of hip,knee and ankle in stroke patients was reduced and the maximal an-gle of hip extension,knee flexion and ankle dorsiflexion was also reduced,but the maximal angle of knee extension was increased significantly as compared with those in the healthy elderly (P<0.05 for all).The gait function was correlated with kinematic parameters (steps per minute,stance percent,the ROM of knee and the maximal angle of knee flexion and ankle plantar flexion)in stroke patients (P<0.05).Conclusion:Because of the motor dysfunction of lower extremities,the walking speed of stroke patients was decreased.The dysfunction of knee flexion and ankle plantar flexion was the important factors that influenced the walking speed in stroke patients with knee hyperexten-sion.关键词
