Rehabilitation related to baby’s muscle tone usually needs to be done for about 3 months. High dystonia may be caused by incomplete development of the nervous system, as well as hypoxic-ischemic encephalopathy, bilirubin encephalopathy, and genetic metabolic disorders. Rehabilitation can be done to improve the dystonia. Usually, the rehabilitation training related to the baby’s muscle tone is 15 days for a course of treatment, about 6 courses of treatment, that is, about 3 months, the baby’s muscle tone will gradually decline to normal. If it is a pathologic dystonia, the time for it to be relieved is related to the severity of the condition and the timing of the rehabilitation training. Generally speaking, try to detect it before 4 months of age and give early intervention, and try to give the intervention treatment before one year of age. And the rehabilitation time is long, from a few months to a few years. If the baby’s high muscle tone does not improve after about 3 months of rehabilitation training, it may indicate parenchymal brain lesions, and it is recommended to seek timely and complete the relevant examinations for targeted treatment.
