Proprioception

The sense of position and movement of the limbs and the sense of muscular tension. The awareness of the orientation of the body in space and the direction, extent, and rate of movement of the limbs depend in part upon information derived from sensory receptors in the joints, tendons, and muscles. Information from these receptors, called proprioceptors, is normally integrated with that arising from vestibular receptors (which signal gravitational acceleration and changes in velocity of movements of the head), as well as from visual, auditory, and tactile receptors. Sensory information from certain proprioceptors, particularly those in muscles and tendons, need not reach consciousness, but can be used by the motor system as feedback to guide postural adjustments and control of well-practiced or semiautomatic movements such as those involved in walking.

Receptors for proprioception are the endings of peripheral nerve fibers within the capsule or ligaments of the joints or within muscle. These endings are associated with specialized end organs such as Pacinian corpuscles, Ruffini's cylinders, and Golgi organs (the latter resembling histologic Golgi structures in the skin), and muscle spindles.

Ankle joint position sense, defined operationally as the ability to replicate joint positions using active or passive movement cues, has usually been measured in an open-kinetic chain mode and in a uniplanar mid-range position, with the subject positioned either in supine (Konradsen et al 1998) or in a seated position (Eils and Rosenbaum 2001, Feuerbach et al 1994, Holme et al 1999, Konradsen and Magnusson, 2000).
Although muscle receptors and or joint and skin sensory receptors are thought to be possible mediators of joint position sense and these may frequently be damaged or impaired functionally in the ankle injured individual, position sense tests conducted by Holme et al (1999) and Gross (1987) with respect to the ankle injured individual (see Table 1) have indicated that, as with 'simulated' ankle sprains, authentic ankle sprains may not affect an individual's ability to match ankle positions, either actively or passively.
