Earlier studies that address assessment of the subtalar joint (STJ) by measuring rearfoot motion used a goniometer to evaluate intertester reliability. Few investigations have determined how positions of the rearfoot, assessed manually (passive range of motion) or statically in one-legged standing, compare with those occurring during walking. The purpose of this study was to determine the following: (1) the intertester reliability of positioning the STJ in neutral, maximum inversion, and maximum eversion; (2) the reliability of the rearfoot position during relaxed one-legged standing; and (3) how these positions compare to rearfoot motion during walking. An electrogoniometer attached to the lateral aspect of the lower leg and heel was used to record the position of the rearfoot during testing procedures. Ten healthy volunteers participated. Rearfoot position was recorded during relaxed one-legged standing and during free and fast walking. Additionally, rearfoot position was recorded while each of three physical therapists positioned the STJ in neutral, maximum inversion, and maximum eversion. Intertester reliability for positioning the STJ in neutral, maximum inversion, and maximum eversion yielded intraclass correlation coefficients of 0.76, 0.37, and 0.39, respectively. Reliability of relaxed one-legged standing had an intraclass correlation coefficient of 0.92. The rearfoot position in relaxed one-legged standing and the maximum eversion position occurring during gait were not significantly different. These findings suggest that there is good intertester reliability in positioning the STJ in neutral. Additionally, the rearfoot position in relaxed one-legged standing may be used to approximate the maximum eversion position that occurs during gait.
早期通过测量后足运动来评估距下关节（STJ）的研究使用测角仪来评估测试者之间的可靠性。很少有研究确定手动评估（被动活动范围）或单腿站立静态评估的后足位置与行走时的后足位置相比情况如何。本研究的目的是确定以下内容：（1）将STJ定位在中立位、最大内翻位和最大外翻位时测试者之间的可靠性；（2）放松单腿站立时后足位置的可靠性；（3）这些位置与行走时后足运动的比较情况。在测试过程中，使用附着在小腿外侧和足跟的电子测角仪记录后足位置。十名健康志愿者参与。在放松单腿站立、自由快速行走期间记录后足位置。此外，在三名物理治疗师分别将STJ定位在中立位、最大内翻位和最大外翻位时记录后足位置。将STJ定位在中立位、最大内翻位和最大外翻位时测试者之间的可靠性，组内相关系数分别为0.76、0.37和0.39。放松单腿站立的可靠性组内相关系数为0.92。放松单腿站立时的后足位置与步态中出现的最大外翻位置无显著差异。这些发现表明，将STJ定位在中立位时测试者之间具有良好的可靠性。此外，放松单腿站立时的后足位置可用于近似步态中出现的最大外翻位置。
