Rate of Force Development vs Isometric Strength of Quadriceps
- Conditions
- Post ACL Reconstruction
- Registration Number
- NCT04005274
- Lead Sponsor
- Kaiser Permanente
- Brief Summary
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.

- Primary Outcome Measures
Name Time Method Limb Symmetry (Noyes hop testing, Isokinetic testing-rate of force development, Isokinetic testing-quadriceps index) March - June 2019 Limb symmetry was calculated comparing surgical leg over non-surgical leg giving a percentage. A percentage will be calculated for each one of the 3 observations allowing easy comparison with same unit of measure.
