Document Summary
Sensory information is essential for all theories of motor control and learning. Focus in this book is on three types: Proprioception: the sensory system"s detection and reception of movement and spatial position of limbs, trunk, and head. Detects changes in muscle fiber length (stretch) and velocity (velocity of the stretch) Involved in voluntary movements: golgi-tendon organs (gto) Not very good in detecting muscle length changes: joint receptors. To answer this question, researchers have investigated the following question: Afferent neural pathways associated with movements of interest have been surgically removed or altered. Large myelinated fibers of the limb are lost, leading to a loss of sensory information. Nerve block technique inflate blood-pressure cuff to create temporary disuse of sensory nerves. High speed vibration of the tendon of the agonist muscle. Spatial and temporal accuracy for movement in progress. Spatial-temporal coupling between limbs and limb segments.
