BACKGROUND
Hop tests are commonly used within a testing battery to assess readiness for return to sport after anterior cruciate ligament (ACL) injury, yet athletes still experience a high rate of re-injury. Simultaneous performance of a secondary task requiring cognitive processing or decision-making may test the athlete under more realistic contexts.
PURPOSE
To examine a clinically feasible, dual-task assessment paradigm applied during functional hop tests in healthy individuals.
STUDY DESIGN
Repeated measures.
METHODS
Participants performed the crossover triple hop for distance (XHOP) and medial triple hop for distance test (MHOP) under three separate conditions: standard procedures and two dual-task protocols including the backward digit span memory task and a visuospatial recognition task. The visuospatial task involved briefly displaying an image consisting of 18 randomly placed red and blue circles on a screen, where the participant was asked to identify the number of red circles in each image. The backward digit span task was applied by introducing a sequence of random numbers to the participants, who were required to repeat the sequence in reverse order. Each motor and cognitive task was performed independently and simultaneously, in accordance with the dual-task paradigm.
RESULTS
Thirty-four healthy participants (age: 24.0 ± 3.9 years) completed testing procedures. No differences in hop distance were observed with the simultaneous application of a cognitive task, with the exception of the backward digit span memory task resulting in decreased hop distance (p = 0.04, d = 0.14). There were no differences in cognitive accuracy according to hop test type, although the effect size was greater for the XHOP (p = 0.08, d = 0.49) compared to the MHOP (p = 1.0, d = 0.07). The dual-task protocol revealed good-excellent within- (ICC3,1 = 0.85 - 0.99) and between-session (ICC3,k = 0.94 - 0.99) intrarater reliability for hop distance across all dual-task conditions. The addition of a cognitive task to the XHOP and MHOP resulted in a lower standard error of measurement and decreased minimal detectable change, as compared to standard testing procedures.
CONCLUSION
The simultaneous application of a cognitive task did not alter hop distance, with the exception of the backward digit span memory task resulting in decreased hop distance with a trivial effect size. There were no differences in cognitive accuracy according to task type (sitting, XHOP, MHOP). All combinations of dual-task assessment demonstrated good-excellent within- and between-session intrarater reliability among healthy individuals, but measurement precision was deficient.

背景
在一系列测试中，单腿跳测试常用于评估前交叉韧带（ACL）损伤后运动员恢复运动的准备情况，但运动员再次受伤的发生率仍然很高。同时执行一项需要认知处理或决策的次要任务，可能会在更现实的情况下对运动员进行测试。
目的
研究一种在健康个体功能性单腿跳测试中应用的临床可行的双任务评估范式。
研究设计
重复测量。
方法
参与者在三种不同条件下进行交叉单腿跳远距离测试（XHOP）和内侧单腿跳远距离测试（MHOP）：标准程序以及两种双任务方案，包括倒序数字广度记忆任务和视觉空间识别任务。视觉空间任务包括在屏幕上短暂显示由18个随机放置的红色和蓝色圆圈组成的图像，要求参与者识别每个图像中红色圆圈的数量。倒序数字广度任务是向参与者提供一系列随机数字，要求他们以相反顺序重复该序列。根据双任务范式，每个运动和认知任务独立且同时进行。
结果
34名健康参与者（年龄：24.0±3.9岁）完成了测试程序。同时进行认知任务时，除了倒序数字广度记忆任务导致单腿跳距离缩短外（p =0.04，d =0.14），未观察到单腿跳距离有差异。根据单腿跳测试类型，认知准确性没有差异，尽管与MHOP（p =1.0，d =0.07）相比，XHOP的效应量更大（p =0.08，d =0.49）。双任务方案显示，在所有双任务条件下，单腿跳距离的组内（ICC[3,1]=0.85 - 0.99）和组间（ICC[3,k]=0.94 - 0.99）评分者内信度良好至优秀。与标准测试程序相比，在XHOP和MHOP中增加认知任务会导致测量标准误差降低，最小可检测变化减小。
结论
同时进行认知任务不会改变单腿跳距离，但倒序数字广度记忆任务除外，该任务导致单腿跳距离缩短，效应量较小。根据任务类型（坐姿、XHOP、MHOP），认知准确性没有差异。双任务评估的所有组合在健康个体中均显示出良好至优秀的组内和组间评分者内信度，但测量精度不足。
