P76-T Motor simulation to counteract the detrimental effects of transient sensorimotor deprivation

Abstract

This presentation depicts an approach aiming to allow individuals with orthopedic trauma injuries to optimize recovery and safely return to daily life. In this approach used alongside conventional physical rehabilitation methods, motor simulation is the core. Based on Jeannerod’s motor simulation theory (1994, 2001, 2006), an individual is engaged in a motor simulation process: (1) when the action is imaged (imaged action); (2) when the action is observed (observed action) or (3) when it is verbally described, either silently or aloud (verbalized action). This communication is thus composed of four parts. The first part provides recent scientific insights on the basis of Jeannerod’s motor simulation. According to Jeannerod, motor simulation is characterized by action-related cognitive states, such as motor imagery or action observation, which activate cortical motor systems similar to those involved during actual action. The second part focuses on recent scientific findings which have investigated the effects of sensory and motor deprivation on motor/cognitive performance and human brain organization. The third part discusses motor simulation training to counteract detrimental effects of transient sensorimotor deprivation, and the last part provides applied perspectives. Currently implemented with injured athletes on a national campus in France, this approach with motor simulation at its core has yielded encouraging results and could be seen as a promising avenue in sport and clinical settings.
