Botox for hypertonia is useful, but the maintenance effect is not long lasting. Botulinum toxin can block the connection between nerve impulses and muscles, and systematically control the local spasm caused by high muscle tone, and the effect is very fast. In clinical practice, it can achieve the purpose of reducing muscle tension and relieving spasm. However, it should be noted that Botox has a limited maintenance time and cannot completely cure hypertonia, usually after three months or six months after injection, the symptoms of hypertonia will reappear again, which is easy to make the condition recurring. Long-term injection of Botox is prone to many complications, even leading to excessive nerve paralysis. It is recommended that patients under the guidance of a professional doctor for treatment, do not inject Botox on their own to avoid adverse consequences.
