This study determined knee joint proprioception in below-knee amputees using two methods of measurement of knee joint proprioception. The threshold for detection of passive motion and the ability to reproduce specific limb positions were recorded in nine below-knee amputees. A significant difference was observed between the prosthetic and sound limbs in the amputees in the threshold of detection test. The large angles (5 degrees to 25 degrees) involved in position reproduction tests may have provided cues through the cuff suspension. Different strategies are used by below-knee amputees to discern large and small movements of the knee.
本研究采用两种膝关节本体感觉测量方法，测定了膝下截肢者的膝关节本体感觉。记录了9名膝下截肢者被动运动检测阈值和再现特定肢体位置的能力。在检测阈值测试中，截肢者的假肢侧和健侧肢体之间观察到显著差异。位置再现测试中涉及的大角度（5度至25度）可能通过袖带悬吊提供了线索。膝下截肢者使用不同策略来辨别膝关节的大、小运动。
