Reciprocal Inhibition

Reciprocal inhibition explains why stretching the posterior chain is more effective than directly targeting the anterior neck for forward head posture correction. Reciprocal inhibition is the physiological mechanism behind the Jefferson Curl — stretching the posterior chain neurologically forces the anterior muscles to relax. Reciprocal inhibition is the process by which stretching a muscle causes the central nervous system to automatically send relaxation signals to the opposing antagonist muscles. Stretching the anterior lower leg muscles sends neurological signals that cause cramping plantar muscles to relax. Stretching the plantar surface or calf directly when they are cramping is counterproductive. The correct approach to plantar cramping is to work the opposing muscle group to trigger reflexive relaxation.
