Sensorimotor integration: basic concepts, abnormalities related to movement disorders and sensorimotor training-induced cortical reorganization Machado S; Cunha M; Velasques B; Minc D; Teixeira S; Domingues CA; Silva JG; Bastos VH; Budde H; Cagy M; Basile L; Piedade R; Ribeiro PRev Neurol 2010[Oct]; 51 (7): 427-36INTRODUCTION: Sensorimotor integration is defined as the capability of the central nervous system to integrate different sources of stimuli, and parallelly, to transform such inputs in motor actions. AIM: To review the basic principles of sensorimotor integration, such as, its neural bases and its elementary mechanisms involved in specific goal-directed tasks performed by healthy subjects, and the abnormalities reported in the most common movement disorders, such as, Parkinson' disease, dystonia and stroke, like the cortical reorganization-related mechanisms. DEVELOPMENT AND CONCLUSIONS: Whether these disorders are associated with an abnormal peripheral sensory input or defective central processing is still unclear, but most of the data support a central mechanism. We found that the sensorimotor integration process plays a potential role in elementary mechanisms involved in specific goal-directed tasks performed by healthy subjects and in occurrence of abnormalities in most common movement disorders and, moreover, play a potential role on the acquisition of abilities that have as critical factor the coupling of different sensory data which will constitute the basis of elaboration of motor outputs consciously goal-directed.|*Psychomotor Performance[MESH]|Cerebral Cortex/*physiology/physiopathology[MESH]|Dystonia/physiopathology[MESH]|Humans[MESH]|Movement Disorders/*physiopathology[MESH]|Parkinson Disease/physiopathology[MESH]|Stroke/physiopathology[MESH] |
