Botulinum toxin improves spasticity
Injections of botulinum toxin A combined with traditional modalities, significantly reduced spasticity and improved range of motion in the wrists and fingers of traumatic brain injury (TBI) patients in a study at the University of Texas Health Science Center in Houston.
In the study, 21 adult TBI patients received 20 to 40 units per muscle of botulinum toxin A followed by range of motion exercises, modalities, and casting. After two to four weeks, mean range of motion improved 42.9 degrees for acute patients and 36.2 degrees for chronic patients.
According to the study, improvement of wrist spasticity and range of motion was consistently noted only after the injections.
