A control unit was designed to allow persons who have lost hand and arm function to control the speed, steering, reversal and on-off switching of an electric wheelchair by means of backward movement and rotation of the head. When possible, shoulder movement was used to control both reversal and on-off switching. Clinical evaluation in 10 patients with quadriplegia and 2 with severe neuromuscular disease showed that the unit neither interfered with nor restrained the patients' residual body movements, permitted use of natural head movements for smooth and fast control of the wheelchair, and was well accepted by and integrated into the life of the patients.
设计了一种控制单元，使失去手部和手臂功能的人能够通过头部的向后移动和转动来控制电动轮椅的速度、转向、倒车和开关。如果可能，还利用肩部运动来控制倒车和开关。对10名四肢瘫痪患者和2名患有严重神经肌肉疾病的患者进行的临床评估表明，该控制单元既不干扰也不限制患者的残余身体运动，允许使用自然的头部运动来平稳快速地控制轮椅，并且被患者很好地接受并融入了他们的生活。
