dystonia
"My daughter had a TBI and used to for muscle spasm .She had previously received Botox injections for several years which became ineffective due to her body building up antibodies to it. She has received several injections of Myobloc which were very positive in helping with contractions in her limbs.It increased her mobility and helped her use her arms and hands. Myobloc improved her quality of life and function with her ADL's.  Myobloc peaks with in a day of injection and wanes throughout several weeks. She has not had adverse side effects. Receiving insurance coverage for Myobloc took an enormous amount of effort and perseverance on both my part and the doctors."
