Official title
Is Rate of Force Development (RFD) Superior to Isometric Strength (QS) of the Quadriceps as a Predictor of Functional Performance After Anterior Cruciate Ligament Reconstruction
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Peak isometric strength of quadriceps (QI) has been used to help determine an athletes ability to safely return back to sport following an anterior cruciate ligament (ACL) reconstruction surgery. However, rate of force development (RFD) of the quadriceps, or how fast the quadriceps are able to reach their peak strength, is rarely used as part of this decision despite the role it plays in protecting the knee. This retrospective data only study will look back at the limb symmetry index (LSI) of patients post ACL reconstruction for the Noyes Hop Test, QI, and RFD. The hypothesis is that RFD does not recover at the same rate as Noyes Hop Test and QI.
