The problem of quads inhibition

After injury or surgery the quadriceps muscle may become markedly inhibited - although the muscle bulk may be the same the fibres have problems triggering a contraction. Short arc extensions help to trigger the quads and this is the next exercise to try to bring them back to life and regain some early range of motion.

This article offers a suite of early knee rehabilitation exercises for the damaged knee.
