Design of a Dynamic Arm Support (DAS) for gravity compensation

摘要

The Dynamic Arm Support, or briefly the Das, is a new medical device that serves to compensate for lost arm function of the severely disabled. The target group suffers from insufficient muscle force to move its arms over the usual Range of Motion (RoM). The purpose of the Das is to assist its user during Activities of Daily Living (ADL) by eliminating gravity acting on the upper limb and enabling the limb to move freely. The development of the Das is presented and discussed, focusing on the modular parts, working principle, unique features, and technical performance as well as results for the target group.udud
