Beyond jump height: monitoring countermovement jump metrics across the Anterior Cruciate Ligament rehabilitation journey.

The countermovement jump (CMJ) test serves as a popular assessment method owing to its relative simplicity, time-efficient nature and ability to elicit consistent and repeatable measures. However, the choice of metrics is vast when undertaking testing with force platforms, which makes it difficult for practitioners to know which ones to monitor and why. This article outlines some of the common challenges that practitioners face when considering the use of this test, some objective markers and subjective information to guide its implementation in practice, in addition to a blend of logic-led reasoning and referral to the existing evidence base, to consider which CMJ metrics may be most appropriate for practitioners to monitor during the rehabilitation journey of those who suffer ananterior cruciate ligament (ACL) injury.
