Abstract

Background: Numerous single leg hop tests have been used as functional measures for return to sport; however, their validity and clinical relevance are in question because they only assess performance in one plane, mitigating a person’s athletic abilities. There is a need for reliable and valid multi-directional functional tests. The purpose of this study was to determine the test-retest reliability of a novel multi-directional timed single leg hop test in healthy subjects.

Methods: Fifty healthy subjects, 23 males and 27 females, ages 18 to 35, (mean age 23.48 with SD 3.82) consented to perform the test. The subjects hopped along a 10ft. x 10ft. shaped course. Subjects performed two maximum effort trials on each leg with 3-7 days rest between retests. Intraclass Correlation Coefficients (ICC) were calculated to determine intersession reliability.

Results: The inter-rater reliability (ICC’s) for the 50 subjects ranged between .98 and 1.00 suggesting excellent reliability. Paired T-tests demonstrated no significant differences between the time scores for the dominant and non-dominant legs (p>.05).

Conclusion: This study demonstrates the T-Drill Hop Test has excellent test retest reliability. These results are important prior to validation and utilization as a clinical functional performance test.
