What are the causes of high muscle tone? Myotonia is a force that is generated when human muscle cells pull each other in a resting and relaxed state, and it is the basis for maintaining various body postures and normal movements. There are many clinical causes of high muscle tone, the most common being brain damage caused by lack of oxygen at birth, which leads to cerebral palsy and high muscle tone. In addition, cerebral infarction and cerebral hemorrhage can also cause hypertonia. The symptoms are scissor gait, pointed feet, inward thumb clasping, flexion of both lower limbs, elbow flexion, forearm rotation, etc. How many levels of muscle tone are there? There are four clinical levels of dystonia: Level 0 is normal dystonia; Level 1 is when the patient has symptoms, such as moving the limbs and resisting external obstacles; Level 2 is when the patient can move the limbs left and right and up and down, but only slightly resisting external forces; Level 3 is when the patient can only move left and right and cannot lift the legs; Level 4 is when the patient basically cannot move and the limbs are In grade 4, the patient is basically unable to move and the limbs are not controlled. Do I have to undergo SPR surgery to reduce muscle tone? In general, spr surgery can be considered for patients with spasticity in all four limbs. For patients with spasticity in one part of the limb, peripheral nerve narrowing can be used to adjust the tone. Peripheral nerve reduction achieves precise regulation of muscle tone and improvement of patient’s symptoms through preoperative, intraoperative and postoperative electrophysiological myoelectric monitoring. The surgical incision is 2-5 cm, removing harmful muscle spasms while preserving the original muscle strength, with excellent results and a quick postoperative recovery that has essentially no impact on the patient’s normal life.
