Brain hemorrhage accounts for 20% to 30% of all strokes, and the death rate in the acute phase is 30% to 40%, posing a serious threat to human health and safety. Most patients have many sequelae even after emergency treatment, and hypertonia is one of the more common clinical sequelae. How is hypertonia treated in brain hemorrhage? The main manifestations of hypertonia are: straightening of the lower limbs, inward crossing, and scissor-like. Many newborns are easily irritated, frightened by the sound, continuously crying, and have difficulty sleeping. It is difficult to insert their arms into the sleeves when dressing, to separate their legs when changing diapers, to break their fists when bathing, and when the lower limbs just touch the bath tub or water surface, the child’s whole body immediately becomes rigid, which seriously affects the limb function of the child. Medication, rehabilitation training and surgery are several ways to treat hypertonia, and medication is mostly used for lighter children, and the effect varies from person to person. Rehabilitation training is a common way to improve hypertonia and limb paralysis, and takes various forms, including moving the large joints of the limbs and massaging the muscles, and intervening with Chinese physical therapy such as acupuncture and tui na. When the condition is stabilized, followed by training in sitting up and standing up to walking, the limb function of most patients can be effectively improved to some extent. In a small number of cases, the results are not good, and further surgical treatment needs to be considered at this time. For patients with myotonia muscle tone grade 2-3 or higher, more severe spasticity that affects daily life, or patients with abnormal limb deformity after traumatic brain injury, peripheral nerve reduction can be considered to restore normal muscle tone and restore the function of the patient’s limbs. The earlier the surgical intervention is performed, the more effective the improvement of hypertonia can often be. In addition, selective posterior spinal nerve root dissection and carotid sympathetic nerve net stripping are also advanced procedures for the treatment of hypertonia, and patients are advised to further define the surgical indications before treatment and then choose the appropriate surgical procedure.
