The role of sensory stimulation on motor learning via action observation: a mini review.

Action observation involves the observation of an action followed by an attempt to replicate it. Recent studies show that increased sensorimotor cortical connectivity improves motor performance via observation and that priming the sensory system before observation enhances the effects of observation-based learning. Understanding the role of the sensory system is, therefore, critical for rehabilitation of movement disorders that have a sensory deficit.
