What causes weakness in the limbs of children?

After birth, children enter an important stage of physical health development and growth, which is crucial for their lives. While some children are growing up healthily, some others show weakness in their limbs and loose legs and feet. This makes many parents particularly worried. So, what causes weakness in children’s limbs? Will this have a great impact on the child's future physical development? Let's find out together.

From newborns to older children, motor functions gradually mature with growth and development, and limb movements develop from uncoordinated and unconscious gross movements to coordinated, purposeful and voluntary movements. Due to congenital or postnatal pathological factors, limb weakness or even paralysis may occur. Common diseases of this type include: nervous system diseases, such as cerebral palsy, 21-disomy syndrome, gangliosidosis, metachromatic leukoencephalopathy, subacute necrotizing encephalomyelitis, congenital cerebellar hypoplasia, progressive muscular atrophy in infants, spinal cord tumors, multiple radiculitis, etc.

Neuromuscular junction disorders or muscle diseases, such as myasthenia gravis, hypokalemic periodic paralysis, congenital muscular dystrophy, dermatomyositis, and polymyositis. Congenital bone, joint and ligament diseases, such as multiple arthrogryposis, osteogenesis imperfecta, and Marfan syndrome. Severe malnutrition, vitamin B deficiency, scurvy. Metabolic and endocrine diseases, such as infantile hypercalcemia, glycogen accumulation types I, V, and VII, hypothyroidism, and hyperadrenocortical disease. There are many diseases that cause myasthenia in children and the causes are complex. Generally, if a child is found to have limb weakness, he or she should be examined and diagnosed by a doctor. The diagnosis can be confirmed by comprehensive analysis of electroencephalogram, electromyogram, head CT, blood biochemistry, etc.

Through the above introductions, you can know that there are many situations and reasons that cause limb weakness in children, such as congenital diseases, muscular atrophy, brain nerve paralysis, or neuritis, etc. Therefore, for children with limb weakness, it is necessary to find out the cause first and then carry out relevant treatment. The physical health of children must not be taken lightly.
