Abstract

Most externally powered hand prostheses for children with a unilateral congenital below-elbow amputation are myoelectrically controlled. All of them are electrically powered. Despite the success of fitting children with this kind of prostheses, there are some disadvantages: prosthetic weight is high, operating speed is low, the system is vulnerable and its size prohibits fitting it to patients with a long fore-arm stump. It will be shown that pneumatic power can overcome most of these disadvantages.

摘要

大多数为单侧先天性肘下截肢儿童设计的外部动力假手是肌电控制的。所有这些假手都是电动的。尽管为儿童安装这种假肢取得了成功，但仍存在一些缺点：假肢重量大、运行速度低、系统易受影响，且其尺寸使得无法为前臂残端较长的患者安装。结果将表明，气动动力可以克服这些缺点中的大多数。
