What is hypotonia? What does a baby usually look like if he has low muscle tone?

It is a disease in which muscles relax due to a variety of reasons, and then muscle resistance decreases, muscle lesions occur, and the range of motion of the joints is abnormally expanded, affecting the resistance to movement.

It refers to a disease in which the development of brain function is impaired, mental retardation occurs, muscle function is gradually decreasing, the body's coordination function is also declining, and calcium deficiency occurs.

Low muscle tone means that your baby does not have the strength to perform effective movements. The baby's low muscle tone will be manifested as weakness in the limbs, unable to stand, unable to sit, and the whole is very soft, if the baby is asked to make a movement, it will be very difficult.

Weakness of the limbs, inability to walk normally, inability to stand normally, inability to learn to sit, developmental delay.

At several stages of the baby's development of gross motor when he is young, parents will be very concerned about the child's muscle tone. So what is muscle tone? What does low muscle tone mean?

Muscle tone refers to the resistance that the child's body will encounter when the muscles pull when exercising, or the muscles that the child pulls when doing various sports, and the muscles themselves will encounterHow much resistance, there is this resistance in everyone. Every moment a person wants to move and perform an activity, muscle tone is needed. Low muscle tone, which means that the child is exercising.

MusclesRelatively flabby, so there is very little resistance. This indicates that the muscles lack normal toughness and appear to be flaccid. Then if the baby's muscle tone is low, there will be the following manifestations.

Generally, hypotonia will be manifested in the infancy of the child, at this time, if the child reaches the age of the month when he can raise his head, he cannot raise his head smoothly, and it looks comparativeNo energyOr when it's time to stand, your baby won't be able to stand either. Or so it seemsMental developmentis relatively slow. The facial expressions are not as natural as those of ordinary children, and there are some morbid words.

Then it is possible that it is a symptom of low muscle tone. If parents notice these symptoms of their children in time, they should take their children to the doctor immediately and let the doctor diagnose them.

In addition to observing the performance of the child's limbs, many parents also find that their child's eye movements are not normal when the baby is three to four months old, for example, yesThe phenomenon of strabismus, or the eye movement is not sensitive, then with the previous point if it is not able to send out after four monthsGigglessoundIf you can't raise your head, then it's likely to be a sign of low muscle tone.

Parents take their children to the hospital. The earlier you intervene, the sooner you intervene, the better the effect. Only when parents pay attention to it, let the hospital judge accurately, and treat the symptoms, can they ensure that the baby can grow up smoothly.

Low muscle tone is a weak ability to stretch muscles. Performances have the baby's habit of curling up and curling up, having no strength to hold things, having difficulty walking, not moving well and not liking to play.

Low muscle tone refers to the child's poor mobility. The symptoms are that the child is unable to do some fine movements, and the child's reaction is relatively slow.

Muscle tone, which refers to the level of anxiety that muscles feel when they stop and passively move, is fundamental to maintaining body posture and normal fitness movements. Low muscle tone is like a torsion spring loose, and the child is always very weak; The higher the muscle tone, the more it looks like a tight torsion spring, and I feel that the child is always tight. The most significant manifestation of hypotonia is that the development of motor movements in the neonatal period is slower than that of children of the same age, such as sitting on the ground, paralyzing there, and learning to crawl and walk takes a long time.

The muscle tension of newborn babies is high or low is abnormal, which may be caused by cranial nerve damage, try to immediately go to the hospital for the child to check, under the guidance of the physician to use drugs for safe medication, can use drugs to nourish the cranial nerves, and at the same time propose to cooperate with each other acupuncture physiotherapy treatment, usually pay attention to the child's exercise, but also be able to inhale hyperbaric oxygen, etc., to prevent complications. In infancy, the external rotation of the lower limbs, the soft arms, the increased range of motion of the elbows and kneecaps, the passive theme activities of the body have no resistance, and the hands of the baby can be pulled from lying on their backs to sitting up in the case of pulling the reaction, and the head hanging back can not be maintained in a straight line with the body.

When it comes to muscle tone, people are likely to be rusty, but in fact, it is simply the energy caused by the traction of heart muscle cells with each other. The tension of a muscle when it is stationary and relaxed, is called muscle tone. Muscle tone is fundamental to maintaining body posture and its normal fitness movements, and is presented in a variety of forms.

The cause of low muscle tone in small babies is first of all congenital genetic lack of nutrition, in addition, crush syndrome is one of the causes, <>

For example, the increase in the labor process, dystocia of pregnant women, intrauterine growth retardation of the fetus, constrainment, ventricular breath, etc., cause cerebral vasospasm, and lack of oxygen causes cerebral ischemia and hypoxia, which is mainly manifested as abnormal muscle tone after birth. Muscle tone refers to the frictional resistance encountered when the body passively lengthens or stretches the muscles, in other words, the frictional resistance encountered when the body moves passively or when the muscles are stretched. There is muscle tone in everyone's body, and because the body is always in posture and activity, it must be in muscle tone.

Low muscle tone refers to muscle relaxation, low resistance during passive movement, and large range of motion of the joints Performance: Some children do not increase muscle tone but decrease, reducing performance such as poor vertical head, unable to sit up, unable to raise head when lying on the stomach, unable to turn over normally, thighs can be divided to 180°, like gymnasts, this is not a normal phenomenon, it may be low muscle tone.

This refers to muscle weakness, symptoms of weakness in the limbs, inability to stand, no crying or fuss, and very soft to hold.

This refers to the muscles, without strength, mainly manifested in the fact that there is no way to fight well, there is no way to sit well, and it is more difficult to crawl.

Symptoms of hypotonia in infants include the inability to move and maintain normal posture. Infantile muscle tone refers to the total tone of the muscles and is the basis for maintaining various body postures and normal movements. The main manifestations of hypotonia are muscle relaxation, decreased voluntary movements, decreased resistance to joint movement, and expanded range of motion.

The following symptoms may occur. Unable to stand. Babies with hypotonia are considered to be softer.

Since muscle tone is the basis for maintaining various postures and movements of the body, muscle tone can act as a scaffold like a bone. Once the scaffolding is broken or lost, it causes the muscles to relax and the body cannot stand upright. Some frogs are in the supine position.

<> **becomes inelastic, normal baby's ** is rosy-colored, shiny, and elastic to the touch; Children with low muscle tone, difficult feeding, stunted growth, **poor elasticity, dull color, no luster. The baby's muscle tension is low, which will be manifested as the muscles are not shiny, the body is shriveled, the baby has little active movement, and the baby does not feel soft when holding it. Babies may have fixed crossbites, frog positions and other conditions.

The baby is thin and weak, unable to smile, and has a stiff facial expression.

Muscle tone is a gentle and continuous contraction. The purpose of muscle tone is to maintain the coordination of posture and movement. Infantile muscle tone is low and is often seen in patients with cerebral palsy.

Early manifestations of hypotonia are inactivity, particularly lack of voluntary movements. As babies age, a variety of asymmetrical, abnormal, and random movements may occur. Babies with hypotonia tend to have poor muscle mass and lack elasticity.

Low muscle tone in the lower extremities when walking can lead to poor balance and repeated falls.

When the baby's muscle tone is low, we should go to the hospital in time to see a doctor and do ** training. The sooner you start, the better. Children with hypotonia show different symptoms at different stages.

In the early stages of onset in children, hypotonia often manifests. At the beginning of walking, one toe spontaneously flexes and the heel cannot touch the ground. This abnormal movement affects only some random movements at the beginning, such as walking forward only and not in other directions, and walking backwards or laterally is completely normal.

Low muscle tone means that the muscles have no strength and the muscles cannot support the movement of the human body. The baby's balance is very weak and easy to fall, the immunity is very low, and it is often easy to get sick, the exercise ability and learning ability are particularly poor, and the child's mood swings are particularly large, and he often cries.

It means that the muscles are very relaxed, and then the resistance is relatively small in the process of passive movement, and the range of motion of the joints is large; If the child has such a situation, then the muscles of the legs are softer and looser to the touch, and there is no strength at all when lifting the legs and hands.

The child's body cannot stand upright, the child is particularly soft, and the child's muscles have no strength, which is low muscle tone. The main manifestations are that the child's learning speed is particularly slow, the motor ability is poor, the balance is poor, and the child is prone to falling.

What does low muscle tone mean? What are the signs of low muscle tone in babies? What is hypotonia?

In medicine, low muscle tone refers to the reduction of resistance encountered by the body to move during muscle relaxation, as well as relaxation due to muscle abdominal expansion and lack of normal muscle toughness. Hypotonia (flaccid infantile syndrome) is caused by a variety of causes. Primary hypotonia includes central hypotonia and peripheral hypotonia, or mixed hypotonia due to both.

The cause of low muscle tone in babies is congenital hereditary dystrophy in the first place. In addition, birth injury is also one of the causes, such as prolonged labor, dystocia, intrauterine growth retardation, embarrassment, asphyxia, etc., causing cerebral ischemia and hypoxia, resulting in cerebral ischemia and hypoxia injury, manifested as abnormal muscle tone after birth.

Signs of low muscle tone in babies:

Baby hypotonia is a common condition in infants and young children. It is characterized by weakness of the legs, lack of strength, inability to raise the head or stand, or joint contractures, mental retardation, facial muscle involvement, and a distinctive appearance of disease. In the case of a cranial nervous system disorder, cerebral palsy develops, and children show symptoms of low muscle tone at a relatively young age.

The specific performance is as follows:

When the baby is 2-4 months old, the symptoms will be more pronounced, and it is easy to gain weight and lactation; You can't laugh for 2 months, laugh for 4 months; If the body twists after 3-4 months, it usually indicates an extrapyramidal injury; Lying prone for 4 months without looking up or sitting upright is usually an important marker of brain injury; When a 3- to 4-month-old baby develops strabismus and poor eye movements, it may indicate brain damage.

Neonatal hypotonia is the main symptom of neurological or muscular disorders, and it can also be a manifestation of central nervous system depression when systemic disease is severe. The main manifestations are abduction of both lower limbs, weakness of both arms, expansion of the range of motion of elbow and knee joints, and no resistance when the limbs move passively. When pulling, the baby can pull his hands from the supine position to a sitting position, and the head should not be in line with the body.

When lifting weights horizontally, the head and limbs are weak and drooping, muscle tone is reduced, and it is often accompanied by faint crying, weak sucking, difficulty swallowing, and decreased voluntary movements.

It refers to the abnormal degree of muscle relaxation. The limbs will be limp, they will show a state of appreciation, their sense of balance will be poor, they will fall frequently, and sometimes the body will be unbalanced.

It refers to muscle relaxation. Babies may experience reduced physical mobility and sometimes general weakness. The baby's ** elasticity is very poor, there is no way to stand upright, and the motor function is very poor.

Low muscle tone is the baby's reaction to the external environment. Hypotonia is manifested by weakness in the hands and feet and the inability to raise the head. You can't look for it with a traveling sound, and you can't do it or climb it.

Congenital or metabolic diseases. It may be caused by the lesions of the cerebral nervous system, various reasons such as prolonged labor, dystocia of pregnant women, intrauterine growth retardation of the fetus, tightness, ventricular breath, etc., will cause cerebral ischemia, insufficient oxygen to cause cerebral ischemia and hypoxia damage, manifested as abnormal muscle strength after birth. It can be caused by a lack of nutrients and a functional disorder.

Embryonic elements: such as premature rupture of membranes, placenta previa, embryonic infarction or poor placental function.

Hypotonia is a subjective decrease in frictional resistance to passive movement and is a neurological (amplitude of muscle tissue stretching and contraction) reduction in muscle tissue. Hypotonia** is complex and divided into congenital and acquired secondary causes. Genetic factors are the most common in congenital **, which can be chromosomal aberrations such as Down syndrome, lack of large genetic fragments such as Prad-Er-Willi syndrome, single gene variants such as muscular dystrophy, and congenital metabolic abnormalities such as phenylketonuria; Acquired secondary disease can be caused by sensitivity, endotoxin, autoimmune disorders, metabolic disorders, and neurological abnormalities.

There are a variety of causes of low muscle tone, which can improve your child's nutritional profile in daily life. In the case of uncertainty, you should go to the local hospital ** department to do a central nervous system assessment, if you need to give the head CT and other corresponding examinations, in order to clarify the diagnosis and level, you must adhere to the ** training, children under the age of three The effect is more appropriate, the older the age, the worse the actual effect Overall, the causes of low muscle tone are various, congenital and acquired, and the severity is also mild and severe.

Congenital gene deficiency of nutrition, muscle strength after birth, reduced joint contractures, mental retardation, facial muscle involvement, will have a distinctive disease appearance. The tendon reflexes are weakened or subsided, creatine phosphokinase in the blood is elevated, and muscle biopsy shows that muscle tissue somatic cells have fallen off and connective tissue is proliferating. Birth injuries are one of the causes, brachial plexus numbness, low muscle tone, passive hyperactivity, and low muscle strength.

Because the bulum and its cranial suture are not closed, the baby can relieve the symptoms of intracranial hypertension through Lufeng dehiscence and hilar bulging doctor-patient conflict, strong work pressure.
