Rehabilitation Physicians, PC offers Botox for the management of migraines, spasticity related to stroke, traumatic brain injury, or spinal cord injury, and for neck spasms caused by cervical dystonia. Used in tiny doses in specific areas, it temporarily reduces muscle contractions for approximately 3 months by blocking the chemical reaction that causes muscles to contract. The FDA approves the use of Botox to treat chronic migraines in adults who are aged 18 or over. About 1% to 2% of people have chronic migraines, which means they get migraine-like headaches 15 or more days every month for at least 3 months. In studies, Botox prevented about 8 to 9 headache days per month, compared to 6 to 7 days per month for patients given a placebo, an inactive treatment. Botox also helps to reduce the chance of permanent muscle and joint contraction as well as the pain caused by severe, constant muscle contraction that occurs in other spasticity related conditions.
