The perception of joint motion and position, or proprioception, is mediated by mechanoreceptors that transduce mechanical deformation into electric neural signals. Highly specialized nerve endings have been found in the joint capsule, GH lie, and tendon surrounding the shoulder joint.

Capsular stretch produces an afferent signal that produces an efferent signal, causing a protective muscular contraction that enhances the stability of the joint when the shoulder joint suddenly rotates to extreme position or translation. In patients with shoulder instability, this mechanism is disrupted but is restored after capsulolabral repair.
