Objectives: 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. Methods: 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. Results: 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). Conclusions: 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.
