摘要

我们研究了机器人辅助运动(LOKOMAT)训练对不完全性脊髓损伤(SCI)患者痉挛踝关节神经肌肉力学特性和自主运动的影响。系统识别技术用于表征Lokomat训练对踝关节机械异常的影响。我们还确定了这种体能训练对踝关节从完全跖屈到最大速度背屈的重复自主运动的影响,并通过测量其运动学参数进行量化。我们发现脊髓损伤时异常增加的反射僵硬度在LOKOMAT训练后显著降低。由于LOKOMAT训练,主动运动范围、峰值速度和峰值加速度均有所增加。这些发现表明,LOKOMAT训练有可能改变异常反射功能和改善受损的自主运动。

Therapeutic effects of robotic-assisted locomotor training on neuromuscular properties
We studied the effects of robotic-assisted locomotor (LOKOMAT) training on the neuromuscular mechanical properties and voluntary movement of the spastic ankle in persons with incomplete spinal cord injury (SCI). System identification techniques were used to characterize the effects of Lokomat training on the mechanical abnormalities of the ankle joint. We also determined the effects of this physical training on repeated voluntary movements of the ankle from full plantarflexion to dorsiflexion at maximum speed, quantified by measuring their kinematics parameters. We found that reflex stiffness, abnormally increased in SCI, was significantly reduced following LOKOMAT training. Active range of motion, peak-velocity and peak-acceleration of voluntary movement increased as a result of LOKOMAT training. These findings demonstrate that LOKOMAT training has a potential to modify abnormal reflex function and improve impaired voluntary movement.
