If your child suffers from severe spasticity due to their Cerebral Palsy, baclofen might be a suitable treatment option. Baclofen is medicine used to treat muscle symptoms that accompany Multiple Sclerosis and Cerebral Palsy. Electric signals from your nerves instruct when to tense up and when to relax your muscles. This becomes abnormal when the nerves are damaged. This causes spasticity, ending with muscles not working as well as they should. Baclofen is a medicine that restores the signals back to normal allowing muscles to work properly.
