Hi
There are a lot of medications used to treat spasticity including baclofen, tizanidine, diazepam, gabapentin, dantrolene, and botulinum toxin. Ofcourse Keppra (levetiracetam) is also helpful in relieving spasticity. In addition to these, physical therapy involving various stretching and relaxing exercise are also recommended to help relieve spasticity.
Best..
