The body’s ability accurate perception of its spatial relationship to its surroundings. It represents automatic communication between peripheral nerves and the brain and determines the body’s ability to respond with appropriate force during activities such as lifting, pushing, or walking. Proprioception is an essential component of balance, equilibrium, and movement. Proprioception mechanisms integrate closely with postural righting reflexes. Proprioceptive receptors are distributed widely throughout the musculoskeletal system as well as the inner ear structures related to balance.
Disturbances of the neuromuscular system can interfere with the body’s proprioception mechanisms by inhibiting or distorting muscle response. Some scientists believe that treatment with dopaminergic medications such as levodopa suppresses proprioception, contributing to dyskinesias.
