Dystonia is the third most common movement disorder after Parkinson's disease and Tremor. It is a neurologic disorder characterized by involuntary, sustained, patterned and often repetitive muscle contractions of opposing muscles that force parts of the body into abnormal and sometimes painful postures. Dystonia can affect any part of the body and while not fatal, it is a chronic and debilitating disorder. Managing dystonic conditions can be difficult in developing countries where there are limited diagnostic and therapeutic resources. The use of botulinum toxin, considered the treatment of choice for many focal or segmental dystonias, is discussed in regard to its cost effectiveness in the setting of limited resources.
Dystonia provides a practical review of the disorder that emphasizes cost-effective evaluation and treatment and advice on how to apply the current knowledge in clinical practice. This text will be a welcome edition to the international literature on the subject.
