Abstract
Motor learning is the process of obtaining motor skills, and can also be regarded as the acquisition of skills involved in muscle performance. During the process, mutual function between perception and movement is thought to play a pivotal role in motor control. In rehabilitation medicine, several attempts have been made to examine the relationship between exercise and functional recovery, especially that of motor after the disorder of central nervous system, from the view of motor learning. The author outlines here some phases of learning theory, fundamental knowledge on neuro-biology, characteristics of motor learning, motor learning viewed from motor control, and essential information necessary for clinical application of motor learning.
