Reciprocal inhibition is a neuromuscular process in which muscles on one side of a joint relax to allow the contraction of muscles on the opposite side, enabling smooth and coordinated movement. [1] This concept, introduced by Charles Sherrington , a pioneering neuroscientist , is also referred to as reflexive antagonism in some allied health ...
A common example of reciprocal innervation, is the effect of the nociceptive (or nocifensive) reflex, or defensive response to pain, otherwise commonly known as the withdrawal reflex; a type of involuntary action of the body to remove the body part from the vicinity of an offending object by contracting the appropriate muscles (usually flexor ...
There are several different types of muscle energy techniques: Post-Isometric relaxation: Treat by engaging the restrictive barrier in all planes. Reciprocal inhibition: Treat by contracting the antagonistic muscles, which causes the agonist muscle to relax through the reciprocal inhibition reflex arc.
Reciprocal inhibition — While agonist muscles contract, contraction of the opposing antagonist muscles is inhibited. (Such as when alternately flexing and extending one's elbow.) Muscle spindles — Sensory nerve endings in muscle detect the change in length of the muscle and its rate of change.
Since Ia interneuron is inhibitory, it prevents the opposing alpha motor neuron from firing. Thus, it prevents the antagonist muscle from contracting. [14] Without having this system of reciprocal inhibition, both groups of muscles may contract at the same time and work against each other. This results in spending a greater amount of energy as ...
Proprioceptor reflex circuits are thought to play an important role to allow fast and unconscious execution of these behaviors, To make control of these behaviors efficient, proprioceptors are also thought to regulate reciprocal inhibition in muscles, leading to agonist-antagonist muscle pairs.

This is referred to as reciprocal innervation. [5] The withdrawal reflex in the leg can be examined and measured, using an electromyogram to monitor the muscle activity in the upper leg (biceps femoris) while applying increasing electrical stimulation to the lower leg (sural nerve) on the same side of the body. The stimulus intensity at which ...
