Abstract
The efficiency of non-invasive techniques including transcutaneous electrical nerve stimulation (TENS) and laser treatments and invasive techniques including lidocaine and botulinum toxin-A injection, in the patients with myofascial pain syndrome (MPS) were compared in this study.
Hundred patients who admitted to Firat University Hospital Pain Department and who were diagnosed as MPS were included in the study. Patients were randomized into four groups and each group consisted of 25 patients. 60 sessions of TENS and 20 sessions of laser treatments were performed to the first and second groups, respectively. Lidocaine and botulinum toxin-A were injected to the third and fourth groups, respectively. 2ml (20 mg) %1 lidocaine was injected to each patient twice a week for one month in Group I. 25 U (0.5 ml) of botulinum toxin-A was injected to each patient only once in Group II. Pain was evaluated with visual analogue scale (VAS), palpable muscle spasm scoring (PMSS) and anesthesiometer at baseline, 15, 30 and 45 days.
There was no statistically significant difference between the groups with respect to age, sex and education level. Pain control was statistically better in Group III compared with the other groups with respect to VAS, PMSS and anesthesiometer scores.
In conclusion, botulinum toxin-A injection provided better pain control when compared to trigger point injection with lidocaine and non-invasive techniques including TENS and laser treatments.
