Test-retest reliability and discriminative ability of forward, medial and rotational single-leg hop tests
- Medial and rotational hop tests have excellent reliability.
BACKGROUND & OBJECTIVE
Single-leg hop tests are frequently conducted as a physical performance measure in non-injured and injured athletes. The advantage of these tests is that they are easy to administer and require minimal time and experience in clinical practice.
Traditionally, single-leg hop tests are mostly performed in the forward direction. Examples are the single and triple hop for distance. However, during athletic activities, multidirectional movements are commonly performed. Therefore, the inclusion of multidirectional hop tests has been recommended . Several multidirectional hop tests have been presented in the literature [2-4], but studies evaluating both relative and absolute reliability measures of these tests, in addition to the discriminative ability to detect limb asymmetries, are lacking.
The objective of this study was two-fold:
(1) to examine the test-retest reliability of single-leg hop tests in the forward, medial and rotational direction; (2) to investigate the discriminative ability to detect limb asymmetries of medial and rotational hop tests in comparison with forward hop tests in ACL-reconstructed patients.
Passing these kind of tests does not implicate that an athlete can immediately return to sport, but rather progress to sport-specific phases.
Two different populations were recruited in this study:
