To investigate the reliability and validity of a functional performance test in patients with chronic ankle instability (CAI).
Cross-sectional study.
All tests were conducted in the practice room of the physical therapy department of the Vrije Universiteit Brussel.
Twenty-nine healthy subjects and 29 patients with CAI were selected. For the main outcome measurements, participants performed a multiple hop test two times, within a 1-week time interval. Subjects hopped on 10 different tape markers and had to try to avoid making any postural correction. Only when subjects stood still were they allowed to continue hopping. The time needed to complete the test and VAS scores for the perceived difficulty were assessed.
In unstable ankles, ICCs of time values were >0.90 (SEM = 2.3 seconds); Spearman rho values of VAS scores were >0.80. When hopping on their unstable ankles, patients (41.1 +/- 12.6 seconds) needed significantly more time to complete the test than healthy subjects (31.4 +/- 5.0 seconds; test: P = 0.000; retest: P = 0.002) or when compared with their unaffected contralateral ankles (38.0 +/- 7.1 seconds; test: P = 0.047; retest: P = 0.009). Only with respect to the dominant ankles, patients (median = 64 mm) perceived the test as significantly more difficult than did healthy subjects (median = 37 mm; test: P = 0.018; retest: P = 0.002). VAS scores of unstable ankles in patients (median = 50 mm) were significantly higher than their contralateral, unaffected ankles (median = 30 mm; test: P = 0.001; retest: P = 0.002).
The multiple hop test is a reliable test demonstrating functional performance deficits in patients with CAI.
探讨慢性踝关节不稳（CAI）患者功能表现测试的信效度。
横断面研究。
所有测试均在布鲁塞尔自由大学物理治疗科的练习室进行。
选取29名健康受试者和29名CAI患者。对于主要结局指标，参与者在1周时间间隔内进行两次多跳测试。受试者在10个不同的胶带标记上跳跃，且必须尽量避免进行任何姿势校正。只有当受试者静止站立时才允许继续跳跃。评估完成测试所需的时间以及主观难度的视觉模拟评分（VAS）。
在不稳定踝关节中，时间值的组内相关系数（ICC）>0.90（标准误=2.3秒）；VAS评分的斯皮尔曼等级相关系数>0.80。当在不稳定踝关节上跳跃时，患者（41.1±12.6秒）完成测试所需的时间显著长于健康受试者（31.4±5.0秒；测试：P=0.000；重测：P=0.002），或与其未受影响的对侧踝关节相比（38.0±7.1秒；测试：P=0.047；重测：P=0.009）。仅在优势踝关节方面，患者（中位数=64毫米）感觉测试比健康受试者（中位数=37毫米；测试：P=0.018；重测：P=0.002）明显更困难。患者不稳定踝关节的VAS评分（中位数=50毫米）显著高于其对侧未受影响的踝关节（中位数=30毫米；测试：P=0.001；重测：P=0.002）。
多跳测试是一种可靠的测试，可证明CAI患者存在功能表现缺陷。
