Many parents don’t know that their child has high muscle tone, why do doctors say that? Why is it caused by dystonia when the child has leg and foot problems? What exactly is dystonia? Why does it have such a serious effect on a child’s limb movement? Here we will introduce to you the importance of myotonia and what kind of harm it may cause when the child has high myotonia. Simply put, it is the force generated by muscle cells pulling on each other. The tension of a muscle at rest and in a relaxed state is called muscle tone. Myotonia is the basis for maintaining various body postures as well as normal movement and is expressed in many forms. For example, when a person is at rest, the tension in the muscles of the body is called resting muscle tone. When the body is standing, although no significant muscle contraction, but the front and back of the body muscles also maintain a certain tension to maintain standing posture and body stability, known as postural muscle tone. The tension of the muscles during movement is called motor tone, which is an important factor to ensure continuous and smooth muscle movement (no trembling, jerking, spasm). So how is muscle tone classified? What level of muscle tone is normal? Usually we medically classify myotonia into five stages, each representing a different meaning, specifically the following: Myotonia is divided into 0-4 levels: Level 0 is normal myotonia; Level 1 is a condition where the child can move both limbs and resist external obstacles; Level 2 is a condition where the patient can move both limbs up and down, but only to external obstacles; Level 2 is a condition where the patient can move both limbs up and down, but only to external obstacles. When the patient’s muscle tone is 4, it can be said that the patient is basically unable to move and the limbs are not under control. This is what we often call the classification of muscle tone. Then some parents will say, since myotonia is so bad, if the myotonia is removed, then it is good? This is a very serious problem. If we don’t have muscle tone in our body, we won’t be able to stand up. Motor function would be paralyzed and we might not even be able to pick up a chopstick. Every day we basically feel in a state of weakness and our muscles are flabby and cannot support our body at all. That’s why muscle tone should not be absent or very high. It requires our self-control to be able to do so, whereas the muscle tone of a spastic pediatric cerebral palsy patient needs to be artificially disturbed in order to restore the effect. What kind of effects and hazards may high muscle tone have on children? 1. If the patient has high muscle tone for a long time, it may lead to the loss of muscle stretching performance. The muscles will be in a state of extension or compression for a long time. In this case, it is likely to cause muscle necrosis; 2, high muscle tone, the child’s limbs are bound, the limbs will be in a state of long-term stiffness. The child’s motor function can be said to be basically paralyzed, I think these are not the situation parents want to see, right? 3, high muscle tone, if it is the upper limbs, may cause the child to lose the ability to speak. If it is the tongue muscle, then the child’s eating will become a problem. These are the possible hazards of hypertonia to the child.
