Exercise with metronome cues for athletes recovering from ACL surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effects of terminal knee extension exercises synchronized with audible metronome cues on neuromuscular control in athletes who have undergone anterior cruciate ligament reconstruction. The focus is on enhancing the activation of the vastus medialis muscle to improve motor unit behavior during rehabilitation. Participants will engage in a single session of this exercise to assess immediate changes in muscle function and control. The study aims to provide insights into how sensory integration techniques can optimize recovery outcomes for athletes post-surgery.

Exclusion Criteria:

* Non-weight bearing within 2 weeks after the operation (prescription from surgeon)
* Hearing problem, such as being unable to hear the metronome sound or being unable to synchronize exercises with the metronome correctly
