Spasticity is commonly encountered clinically, and always affects patients’ motor ability and capacity for self-care which necessitates intervention. At present, numerous methods have been proposed with varying effects. Many reports show that the most effective method is to inject botulinum toxin, type A (BTX-A) into the spasming muscles, but the doses are different. The guidline of BTX-A injection in Chinese adults is restricted to 600 IU each time within 3 months. In this article, we treated two brain injury patients with severe regional spasticity with overdose of China-making BTX-A whose trademark is HengLi. The treatment improved spasticity and with little adverse effects. We therefore conclude that overdoses of BTX-A could also be safe and more efficient used in some patients who are showing severe spasticity of limb muscles, but it should be vary with each individual and a large sample size trial is needed for a further confirmation.
