A kinematic study was performed to examine the influence of elbow position on the range of supination and pronation of the forearm. The ranges of supination and pronation were measured in 50 volunteers (25 men and 25 women) using a custom-designed jig which constrained unwanted and confounding movements of the limb. Measurements were taken with the elbow in full extension, 45 degrees flexion, 90 degrees flexion and full flexion. The data showed a reciprocal relationship between the range of supination and the range of pronation of the forearm which depended on the degree of elbow flexion. As the elbow is flexed, the maximum angle of supination increases while the maximum angle of pronation decreases (p<0.001). The converse is true as the elbow is extended (p<0.001).
进行了一项运动学研究，以检查肘部位置对前臂旋后和旋前范围的影响。使用定制设计的夹具测量了50名志愿者（25名男性和25名女性）的旋后和旋前范围，该夹具可限制肢体不必要的和混杂的运动。在肘部完全伸展、45度屈曲、90度屈曲和完全屈曲的情况下进行测量。数据显示，前臂旋后范围和旋前范围之间存在反比关系，这取决于肘部屈曲程度。随着肘部屈曲，旋后最大角度增加，而旋前最大角度减小（p<0.001）。当肘部伸展时情况相反（p<0.001）。
