There is a need for a valid, reliable, and easily applicable clinical measure of the length of the Achilles tendon (AT) after rupture. This study examines the reliability of a new ruler based measurement, the Achilles Tendon Length Measure (ATLM) in comparison with the goniometer-based Achilles Tendon Resting Angle (ATRA).
Measurements were performed by two independent physiotherapists eight weeks after AT rupture on 28 patients treated non-operatively.
The mean (SD) injured ATLM was 56.5 (2.3)cm, ICC 0.91(CI [0.72-0.97]), SEM 0.7cm (SEM% 1.2), MDC 1.9cm (MDC% 3.4). Corresponding data for the injured ATRA was mean 64.4° (3.9°), ICC 0.84 (CI [0.68-0-92]), SEM 1.5° (SEM% 2.4), MDC 4.3° (MDC% 6.6).
Both ATLM and ATRA showed excellent inter-rater reliability with low measurement error. Both measurements seem easy to use in clinical practice and potentially providing an indirect measure of the length of the AT after rupture.
需要一种有效、可靠且易于应用的测量跟腱断裂后长度的临床方法。本研究将一种基于新直尺的测量方法——跟腱长度测量法（ATLM）与基于量角器的跟腱静息角（ATRA）相比较，检验其可靠性。
在28例非手术治疗的患者跟腱断裂8周后，由两名独立的物理治疗师进行测量。
受伤后的ATLM均值（标准差）为56.5（2.3）cm，组内相关系数（ICC）为0.91（可信区间[0.72 - 0.97]），测量标准误（SEM）为0.7cm（SEM% 1.2），最小可检测变化值（MDC）为1.9cm（MDC% 3.4）。受伤后的ATRA相应数据为均值64.4°（3.9°），ICC为0.84（可信区间[0.68 - 0.92]），SEM为1.5°（SEM% 2.4），MDC为4.3°（MDC% 6.6）。
ATLM和ATRA均显示出良好的评分者间可靠性和低测量误差。两种测量方法在临床实践中似乎都易于使用，并且有可能间接测量跟腱断裂后的长度。
