High muscle tone can be improved by exercise training, postural changes, botulinum toxin injections, and oral medications. High muscle tone is usually a neurogenic lesion, especially upper motor neuron lesions, which can lead to increased muscle tone. It can be improved by exercise training, such as deep muscle electrical stimulation and distraction therapy, to relieve muscle tone. Increased muscle tone can also be suppressed by changing posture during rehabilitation. For some stroke patients, who have no significant effect through exercise training and postural control, botulinum toxin injection can be performed, which is guided by ultrasound or electrical stimulation on muscles with high muscle tone. It can also be improved by oral medications, such as baclofen and tizanidine. The appearance of high muscle tone needs timely medical treatment, standardized treatment, drugs need to be used under the guidance of a doctor.
