The purpose of this study was to investigate the immediate effect of Walkbot gait training on knee joint stiffness in an individual with spastic hemiplegia.
A woman with hemiparetic stroke underwent a 30-minute Walkbot robotic-assisted gait training session. Knee flexion stiffness associated with hamstring spasticity and knee extension torques during the terminal swing phase was determined before and after the intervention using the Walkbot-STIFF measurement system.
Descriptive case analysis.
Knee joint extension kinematic at the terminal swing phase increased from 2.44° to -0.28°. Knee joint torque increased from 0.26 Nm to 0.32 Nm. The knee flexion stiffness decreased from 0.0083 Nm/degree to 0.0022 Nm/degree following the training.
The Walkbot robotic-assisted locomotor training was effective for reducing knee joint stiffness and improving extensor torque during functional gait. Moreover, the Walkbot-STIFF system was useful for assessing and monitoring spasticity during locomotor training.
本研究旨在探讨 Walkbot 步态训练对痉挛性偏瘫患者膝关节僵硬的即刻影响。
一名偏瘫脑卒中女性患者接受了 30 分钟的 Walkbot 机器人辅助步态训练。使用 Walkbot-STIFF 测量系统在干预前后分别测定了与腘绳肌痉挛相关的膝关节屈曲僵硬度和终末摆动阶段的膝关节伸展扭矩。
描述性病例分析。
终末摆动阶段膝关节伸展运动学从 2.44°增加到-0.28°。膝关节扭矩从 0.26 Nm 增加到 0.32 Nm。训练后膝关节屈曲僵硬度从 0.0083 Nm/度降低到 0.0022 Nm/度。
Walkbot 机器人辅助运动训练可有效降低膝关节僵硬度，并改善功能性步态中的伸肌扭矩。此外，Walkbot-STIFF 系统可用于评估和监测运动训练期间的痉挛。
