Botulinum toxin (BoNT) and back pain.
Myofascial pain syndrome is defined as subacute or chronic pain with sensory, motor and autonomic symptoms referred from active trigger points with associated painful dysfunctions. Authors present the usefulness of botulinum toxin A or B (BoNT/A or BoNT/B) injected into target muscles since the toxin is capable of controlling not only the muscular spasm but mostly the pain by alternative mechanisms of action, which are discussed. Posology of BoNT, technical aspects and results are presented. BoNT represents an interesting and useful tool for an adequate management of patients with myofascial pain.
