Physical therapists often use videography to accurately measure joint kinematics. The purpose of this study was to determine how the maximal calcaneal inversion and eversion angles are affected while running in individuals with a limb length difference between 1.27 cm (1/2 inch) and 1.9 cm (3/4 inch). Twelve subjects with a limb length difference were videotaped using 60-Hz digitized videography while running on a treadmill. Data were obtained for maximum calcaneal inversion and eversion values. Repeated measures analyses of variance were used to determine if significant differences were evident between the lower extremity. Significant differences were not found between the short and long limb for the maximum amount of calcaneal inversion and eversion range of motion. Since calcaneal inversion and eversion are important components of subtalar joint supination and pronation, respectively, the results suggest that subtalar joint kinematics were not significantly altered.
物理治疗师经常使用摄像技术来精确测量关节运动学。本研究的目的是确定在下肢长度差异在1.27厘米（1/2英寸）至1.9厘米（3/4英寸）的个体跑步时，最大跟骨内翻和外翻角度会受到怎样的影响。十二名有下肢长度差异的受试者在跑步机上跑步时，使用60赫兹数字化摄像技术进行录像。获取了跟骨最大内翻和外翻值的数据。采用重复测量方差分析来确定下肢之间是否存在显著差异。在最大跟骨内翻和外翻运动范围方面，短肢和长肢之间未发现显著差异。由于跟骨内翻和外翻分别是距下关节旋后和旋前的重要组成部分，结果表明距下关节运动学没有显著改变。
