To describe mechanographic tests that can be performed by patients with a range of functional abilities and to assess the reproducibility of test results in healthy adults and children.
Fifteen adults and 13 children underwent two separate sessions, one week apart. Participants performed five different tests in both sessions: Multiple one-legged hopping, multiple two-legged hopping, single two-legged jump, heel-rise test, chair-rise test. All measurements were recorded with a portable force platform.
The main outcome measures of each test (peak force relative to body weight or peak power relative to body weight, depending on the test) showed no systematic differences between Session 1 and 2 for any of the test results. Coefficients of variation for the suggested main outcome parameters ranged between 3.4% and 7.5% for multiple one-legged hopping, multiple two-legged hopping, single two-legged jump and the heel-rise test, but were higher for the chair-rise test (8.0% in adults, 15.6% in children).
The five mechanographic tests assessed in the present study yield reproducible outcome measures in healthy subjects. It is justified to evaluate the usefulness of these tests in different patient populations.
描述不同功能能力的患者可进行的力学测试，并评估健康成人和儿童测试结果的可重复性。
15名成年人和13名儿童分别接受两次测试，间隔一周。参与者在两次测试中均进行五项不同测试：单腿多次跳跃、双腿多次跳跃、单腿双腿跳、提踵试验、坐立试验。所有测量均使用便携式测力平台记录。
每项测试的主要结果指标（取决于测试，相对于体重的峰值力或相对于体重的峰值功率）在第一次测试和第二次测试的任何测试结果之间均未显示出系统差异。对于单腿多次跳跃、双腿多次跳跃、单腿双腿跳和提踵试验，建议的主要结果参数的变异系数在3.4%至7.5%之间，但坐立试验的变异系数较高（成人中为8.0%，儿童中为15.6%）。
本研究评估的五项力学测试在健康受试者中产生了可重复的结果指标。评估这些测试在不同患者群体中的有用性是合理的。
