Early treatment is expected to be normalized, but it is necessary to evaluate the children in detail before reaching a conclusion. Muscle tension is the basis of maintaining various postures and normal movements of the body, and it is manifested in many forms. For example, when people are resting in repose, the tension of muscles in various parts of the body is called static muscle tension. When the body stands, although the muscles do not contract significantly, the muscles before and after the body also maintain a certain tension to maintain the standing posture and body stability, which is called postural muscle tension. Muscle tension during exercise, called exercise muscle tension, is an important factor to ensure continuous and smooth muscle movement (no trembling, convulsions and spasms). However, high muscle tension is manifested as: the lower limbs are straight, adduction crossed and scissors-shaped.
