Myotonia, which is the basis for maintaining various body postures as well as normal movement, is not a disease in itself, but merely a pathologic sign of some disorders. Hypertonia is abnormal and often manifests itself as a scissor-like movement of the lower limbs in a straight, inwardly crossed position. Congenital developmental abnormalities, as well as low birth weight and traumatic brain injury, are common causes of dystonia. Brain developmental anomalies are the most common and the leading cause. It is often seen in acute and chronic damage to brain tissue caused by inadequate cerebral perfusion and hypoxia. Respiratory and cardiac arrests are also seen in shock, CO poisoning, status epilepticus, and myasthenia gravis, and are mainly associated with perinatal asphyxia. Treatment requires a specialized neurological examination by a neurologist to determine the grade of the muscle before treatment is based on the cause. The earlier the treatment, the better, the general prognosis is not very good is difficult to completely cure.
