Kinesthesis is the sense of the position and movement of the body parts. Receptors in muscles, tendons, and joints continuously report the angles of the limbs and the forces acting on them.

Without kinesthesis, coordinated movement would be nearly impossible. The system allows a person to touch their nose with eyes closed, to walk without watching their feet, and to adjust grip force to the weight of an object. It works in close partnership with the vestibular sense, which reports head position and movement, and with vision, which provides external spatial reference. When kinesthetic feedback is disrupted—by anesthesia, certain neurological conditions, or temporary experimental interference—movements become clumsy and poorly calibrated.

Kinesthesis operates largely outside awareness until attention is directed to it or until something goes wrong. Athletes, dancers, and musicians develop refined kinesthetic sensitivity that supports precise control. The same receptors contribute to the sense of effort and to the detection of passive movement imposed by external forces.

Every skilled movement relies on a continuous stream of kinesthetic information that most of the time goes unnoticed.
