Definition


Amyotrophy indicates a drop in striated muscle volume. The striated muscles are the muscles that are moved voluntarily by the individual, also called skeletal muscle, and the cardiac muscle. It can arise from an incapacity to use a muscle as in the case of paralysis or a time of inactivity as in an immobilization due to a fracture, for example. Occasionally, it is a neuromuscular condition that can begin during infancy: the nervous cells located in the spinal cord degenerate and involve a melting of the muscle and a loss of strength. Among other pathologies responsible for amyotrophy, amyotrophic lateral sclerosis or poliomyelitis can be cited.
