Usually after a brain hemorrhage occurs, it will lead to neurological damage and interfere with the functional situation of the body, thus causing a series of problems, hypertonia is one of the more common clinical conditions. The manifestation of hypertonia Myotonia and muscle tension are regulated by the cone system and the extrapyramidal system. When brain hemorrhage occurs, especially spontaneous brain hemorrhage, it will lead to damage to the cone system or the extrapyramidal system, which will cause hypertonia. High muscle tone can affect the patient’s motor function, such as scissor step, bilateral lower limb flexion, elbow flexion, forearm rotation, heel not touching the ground, thumb inversion, foot inversion, etc. High muscle tone can cause many problems, such as affecting the random movement of the limb, and generally patients with high muscle tone after the disease, especially those who need to receive rehabilitation training, will affect the recovery and the process of the later. It can also cause pain in the affected limb, and when the pain is severe, it can affect the quality of sleep and even normal life and work; high muscle tone can also cause joint contracture and deformation of the limb, and patients with serious conditions can face great difficulties in taking care of themselves. Treatment of myotonia Generally speaking, increased myotonia usually does not decrease on its own, so it is necessary to take some measures to adjust the value to the normal range. Many patients start out with rehabilitation to help reduce the myotonia, which may have some effect in the short term, but in the long term, it is long and ineffective. In fact, now that medicine is so advanced, surgical interventions can be used to achieve a full adjustment of muscle tone and can provide long-term, stable improvement in the patient’s painful muscle spasms.
