Kinesthesia, Kinesthetic Perception
The “sixth sense” was what Sir Charles Bell, late last century, named the sense of the positions and actions of the limbs. In its entirety, Bell’s sixth sense concerns perceived sensations about the static position or velocity of movement (whether imposed or voluntarily generated) of those parts of the body moved by skeletal muscles, together with perceived sensations about the forces generated during muscular contractions even when such contractions are isometric. The general descriptive terms used today for such sensations are kinesthetic (which despite its literal translation was coined by Bastian to describe this complex of sensations, including those in which movement is not a feature), and proprioceptive (which was used by Sherrington in a rather wider vein than here to include also vestibular sensations and inputs from muscles and joints that are not necessarily perceived, that is, sensations about which one might not be able to give a subjective report).
