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.
