High level, upper extremity amputees have been observed to have problems affecting overall prosthetic function. These include: tendency of the Northwestern Ring to ride upward and difficulty with terminal device function above 90 degrees of elbow flexion. A simple modification of the control strap was tried to resolve these problems of function. The control strap was attached across the back to a buckle on the unamputated side at the shoulder to provide a more efficient anchor. This created more body contact across the back and formed a type of "Z" strap allowing full freedom of movement in any direction. Less forward shoulder flexion was necessary due to decreased cable travel and because the strap was not sliding up and over the shoulder. A single case study is described and the successful outcome for the amputee.
据观察，高位上肢截肢者存在影响整体假肢功能的问题。这些问题包括：西北环向上滑动的趋势以及在肘部屈曲超过90度时终端装置功能出现困难。为解决这些功能问题，尝试了对控制带进行简单修改。将控制带穿过背部连接到未截肢一侧肩部的扣环上，以提供更有效的固定点。这样在背部形成了更多的身体接触，并形成了一种“Z”形带，允许在任何方向上完全自由移动。由于电缆行程减少且控制带不会在肩部向上滑动，因此减少了肩部向前屈曲的程度。本文描述了一个单病例研究以及该截肢者取得的成功结果。
