Discharge Characteristics of Joint Receptors in Relation to their Proprioceptive Role
Since the observation that muscle vibration produces illusions of movement and results in significant impairment in kinaesthesis (Goodwin et al., 1972) increasing emphasis has been placed on their contribution to this sensation whilst the contribution of joint receptors has concurrently been diminished. It has even been suggested that the latter make no significant contribution to the conscious awareness of limb movement and position (Matthews, 1982). The object of this work is to demonstrate that certain experimental manipulations can result in disturbances of kinaesthesis (awareness of limb movement) and stataesthesis (awareness of limb position) and that these deficits can most readily be explained by the response of joint receptors to these procedures.
