KEA vs Towel for Early Quad Activation Post Anterior Cruciate Ligament Reconstruction

A portable, non-electric device consisting of an inflatable cushion, pressure gauge, and digital counter. It provides objective feedback during isometric quadriceps exercises after ACL reconstruction. The device encourages full contraction by only counting repetitions that exceed a preset pressure threshold and return to baseline.

Standard rehabilitation method using a rolled towel under the knee during quadriceps setting exercises. Patients perform isometric contractions without feedback or objective measurement. Repetitions are manually counted by the physiotherapist.
