What is the cause of low muscle tone in babies?

Low muscle tone is a disease that often occurs in infants and young children. Its main manifestations are weak legs, no strength, inability to raise head, inability to stand, etc. After this disease is discovered, it is necessary to go to the hospital for examination and treatment in time. The earlier the treatment, the better the effect. In daily life, the baby should do more recovery exercises. There are many reasons for the baby's low muscle tone, which are mainly manifested in the following points:

1. Reason 1

The first is congenital genetic malnutrition, which leads to reduced muscle tone after birth, joint contracture, mental retardation, and involvement of facial muscles, resulting in a unique diseased appearance. Tendon reflexes are weakened or disappeared, creatine phosphokinase in the blood is elevated, and muscle biopsy shows shedding of muscle fiber cells and hyperplasia of connective tissue.

2. Reason 2

Duchene type and malnutrition are related to sex chromosomes. The incidence rate in males is relatively rare. The disease occurs before the age of three. The patients are characterized by low muscle tone, delayed motor development, and mental retardation. Myogenic muscular atrophy and pseudohypertrophy may also be seen. Electromyographic examination showed increased myoelectric potential and high-frequency discharge.

3. Reason three

Chronic leukodystrophy is an autosomal recessive genetic disease of lipase metabolism disorder. This disease will cause intellectual impairment and further worsening of symptoms, including decreased response to the environment, loss of language ability, screaming, increased muscle tone of the limbs, decreased muscle tone of the trunk and neck, hyperreflexia of the tendons, and slow pupil reflex to light, and inability to inject.

4. Reason 4

Birth trauma is also one of the causes, brachial plexus paralysis, low muscle tone, passive hyperactivity, and low muscle strength. Because the baby's fontanelle and cranial suture have not yet closed, the high pressure can be relieved by opening the fontanelle and bulging the fontanelle to reduce the symptoms of increased intracranial pressure.
