Muscular hypotension in children
Muscular hypotension in children – this is a decrease in muscle tone, the condition develops primarily in children. Weakened muscle fibers in response to nervous stimulation contract very slowly and can not provide the degree of response of the muscle reaction to the same extent as normal muscle tissue. Hypotension of muscles in children is a symptom that can be triggered by many diseases of different etiologies.
Hypotension in children, also called the muscle weakness syndrome, is one of the causes of the development of muscular dystrophy. Low muscle tone can be caused by various causes. Often this condition indicates the presence of disorders in the central nervous system, genetic disorders or muscle developmental malformations. Muscle tone is the strain or degree of resistance to movement in the muscles. Hypotension is not an analogue of muscle weakness, which manifests itself in the form of a decrease in muscle strength, but it can be accompanied by this symptom. In a normal state, the muscle tone determines the ability of the muscles to respond to the stretching of the fascia and muscle fibers. For example, the bent hands of a child with a normal level of tone quickly straighten, the flexor muscles of the shoulder (biceps) quickly straighten in response to this action. Once the action is completed, the extensor muscles relax, and return to their normal resting state.
In a child with a low muscle tone of the fibers, the muscles do not rush to begin contractions. They give a slow response to the nerve stimulus and can not hold the limb in a certain position for a long time.
