The so-called muscle tension refers to the tension of muscles and is the basis for maintaining various postures and movements of the body. Normal people in the quiet and relaxed state, the implementation of daily activities and engaged in active exercise completely different muscle tension, abnormal muscle tension must be checked by the neurologist or neurological rehabilitation personally after the baby to make a correct decision, not non-professional The doctor or the parent subjectively criticized.
Normal infants show an increased muscle tone after birth, and the entire neonatal period will show a significant increase in flexor tone. In the prone position, the limbs flex under the abdomen, showing a high buttocks lower position; when supine, the limbs flex, and the head is biased to the side. Symmetrical limb stretching, angular archbone reversal, playfulness, and breathlessness are more pronounced when crying. This phenomenon of increased flexor tone of the limbs is called the first flexion phase of normal infant postural development.
In 2-3 months, the baby's flexor tension gradually weakens, and the extensor muscle tension gradually increases. When lying prone, the head is forced to rise, the neck is stretched, and it gradually turns to the head and lower buttocks, and the supine limb exhibits an asymmetric limb stretching. Gradually appear symmetrical hands on the chest, eat hands, head to one side or to the midline, turn left and right to follow the 90-180 degrees, crying will still appear to play straight, head back, but the head and neck when pulled up in a quiet state It can be flexed. The phenomenon of muscle tension at this age is called the first stretch of posture development.
Infants reappeared with increased flexor tension at 4 to 6 months. In the prone position, the elbow support lifted 90 degrees and left and right flexibly turned and followed. The fore chest was off the bed or gradually showed hand support; when the supine position, the limbs were symmetrically buckling, both hands Both feet will rest on the midline, can eat hands or grasping things, no longer have asymmetry postures, when the active head and neck flexion and elbow flexion sit up, this phase is the second flexion phase of postural development.
Therefore, infants should not be misjudged as abnormal or lack of oxygen in the early development of muscle tone, and they must not seek excessive medical treatment and cause unnecessary trauma to the baby's young mind.
So here are a few suggestions I gave to my mother:
1, careful control of the baby's performance, as long as they do not accompanied by the ability to develop backward levels, abnormal nerve reflexes and movement quality / posture abnormalities, simple increase in muscle tone are mostly normal baby development of the phenomenon.
2. For premature infants, twin babies, or other infants at risk factors for perinatal brain injury, or parents who are particularly uncertain about muscle tension, they must seek specialist help.
3, in the baby's emotional relaxation, to the baby to do passive exercises, such as when the baby yawns or stretches, you can follow the position to the baby to pull the leg, stimulate the development of Bao Da's nervous system, at the same time, is also very brain development helpful.
Note: In the passive exercise for the baby, many parents blindly apply force and will find that the baby has reflexive exercise. Here, I want to remind parents that when they are doing passive exercises for their baby, they must be relaxed in their baby's mood. , do with the state of cooperation.
