Description
ABSTRACT: Trigger point injections with different solutions have been studied mainly with regard to the management of myofascial pain (MFP) patient management. However, few studies have analyzed their effect in a chronic headache population with associated MFP. The purpose of this study was to assess if trigger point injections using botulinum toxin, lidocaine, and dry-needling injections for the management of local pain and associated headache management. Forty-five (45) myofascial pain patients with headaches that could be reproduced by activating at least one trigger point, were randomly assigned into one of the three groups: G1, dry-needling, G2, 0.25% lidocaine, at 0.25% and G3 botulinum toxin and were assessed during a 12 week period. Levels of pain intensity, frequency and duration, local post-injection sensitivity, obtainment time and duration of relief, and the use of rescue medication were evaluated. Statistically, all the groups showed favorable results for the evaluated requisites (p [less than or equal to] 0.05), except for the use of rescue medication and local post injection sensitivity (G3 showed better results). Considering its reduced cost, lidocaine could be adopted as a substance of choice, and botulinum toxin should be reserved for refractory cases, in which the expected effects could not be achieved, and the use of a more expensive therapy would be mandatory. **********
