Description: The effectiveness of Botulinum Toxin Type-A (BTX-A) injections was compared with lidocaine injections for the management of head and neck myofascial pain. Following injection, eighteen female subjects performed daily exercises and received a multi-week course of physical therapy. Recall appointments occurred at 4, 8, and 12 weeks.A significant reduction in VAS pain intensity scores was noted in both groups (BTX-A 43.9% decrease, lidocaine 51.6%), but there was no difference between groups. BTX-A subjects reported decreases across all sub-categories of the McGill Pain Questionnaire and one Pain Disability Index sub-category. No differences were noted between groups in muscle tenderness scores, compliance with home exercises, or amounts of analgesics required. BTX-A subjects reported more adverse events.Trigger point injections followed by physiotherapy appear to be effective in reducing pain intensity scores for head and neck myofascial pain. BTX-A may have added benefits in modulating qualitative aspects of the pain experience.
