What are the symptoms of low muscle tone in the baby's legs

Muscle tension is actually the force of traction between muscle cells, and muscle tension can also maintain the body in various postures. However, some babies have low leg muscle tension. There are many reasons for this, such as myasthenia gravis or peripheral neuropathy and neuritis, etc. Therefore, parents should find the cause according to the baby's performance. So what are the symptoms of low leg muscle tension in babies?

First, what are the symptoms of low muscle tone in the baby's legs? Muscle tone is the basis for maintaining various postures and basic movements. A normal baby's muscles are rosy, plump, shiny and very elastic. Babies with low muscle tone have poor elasticity, and in severe cases, the muscles look shallow and shriveled. The baby feels very soft when I hold him, and it seems like he has no strength and he rarely moves actively. When the muscles relax, the resistance encountered by the active body decreases, and the muscles lack an expanded belly and normal toughness and become relaxed. In the early stages of acute spastic paraplegia, there will be hypotonia and petit mal seizures.

Second, level 0 normal muscle tension. Level 1 slightly increased muscle tension: when the affected part is passively flexed and extended, there is minimal resistance at the end of the joint range of motion, or there is a sudden jam and sudden release. Level 1 slightly increased muscle tension: there is a sudden jam in the last 50% of the joint range of motion, and then there is minimal resistance in the last 50% of the joint range of motion. Level 2 more obvious increase in muscle tension: when passing through most of the joint range of motion, the muscle tension is more obviously increased, but the affected part can still be moved more easily. Level 3 severe increase in muscle tension: passive movement is difficult. Level 4 stiffness: when the affected part is passively flexed and extended, it is stiff and cannot move.

What are the symptoms of low muscle tone in a baby's legs? Low muscle tone includes weakness in the limbs and the inability of the limbs to resist gravity. Unable to stand, sit, etc. You can do some auxiliary exercises, such as helping to turn over, crawl, and swim (special swimming equipment for babies). When muscle tone reaches its extreme, it becomes paralysis. You can understand it this way: the lower the tone, the less strength you have. Muscle tone refers to the symptoms of muscle contraction when a child responds to external stimuli. Low muscle tone is commonly known as muscle weakness, which is usually manifested in a lack of strength to grip objects, physical fatigue and unsteady walking.
