Our Experience of Muscle Afferent Block for dystonia and spasticity

抄録

Muscle Afferent Block (MAB) has been shown to improve clinical symptoms of writer's cramp, cervical dystonia, spastic paraparesis, and oromandibular dystonia. However, this therapy is not yet used to a sufficient extent. In this article, we review our experience with this new treatment The subjects were 11 cases encountered between November,2001 and April,2002, including 4 cases of focal dystonia of an upper limb,3 cases of spastic paralysis of an upper limb,3cases of spastic paraparesis, and 1 case of spasmodic torticollis. All patients exhibited some clinical improvement. Two cases of facial flushing and 3 cases of muscle weakness occurred as side effects. All of them were mild and transient. We conclude that MAB is a useful treatment for dystonia and spasticity with low incidence of side effects.
