Electro-mechanical devices can help a variety of patients with motor disabilities. Surface EMG from remaining muscles in an amputated arm can be used to control powered electronic hands, wrists and elbows. Sensory signals such as knee angle and ankle torque can be used to control the visco-elastic properties of a knee joint for above-knee amputees. Finally, percutaneous electrodes can be used to stimulate paralyzed muscles to replace hand function in quadriplegics and leg function in paraplegics. This article summarizes recent progress in each of these areas.
机电设备可以帮助各类运动功能障碍患者。截肢手臂中残留肌肉的表面肌电图可用于控制电动义肢的手、腕和肘部。诸如膝关节角度和踝关节扭矩等感觉信号可用于控制膝上截肢者膝关节的粘弹性特性。最后，经皮电极可用于刺激瘫痪肌肉，以替代四肢瘫痪者的手部功能和截瘫者的腿部功能。本文总结了这些领域各自的最新进展。
