Objective
To evaluate the efficacy of topical vibratory stimulation for reducing pain during trigger point injection (TPI). Design Double-blind randomized placebo-controlled clinical trial. Setting Tertiary care university hospital. Participants A total of 136 participants were randomly recruited from among patients with myofascial pain syndrome who were scheduled for TPI. Of these, 65 were excluded because they met the exclusion criteria, and 11 because they refused to participate. Finally, 60 participants were enrolled. No participants dropped out of the study. Intervention Participants were randomly assigned to the vibration group or control group. TPI was performed with 0.5% lidocaine using a 25-gauge needle. A vibrator was applied to the popliteal fossa for 3 to 5 seconds prior to and during TPI to the gastrocnemius; 100-Hz vibration was turned on for the vibration group and turned off for the control group. Main Outcome Measures Pain intensity during TPI was assessed using a 100-mm visual analog scale (VAS) as a primary outcome, and participant satisfaction and preference for repeated use were measured using 5-point Likert scales as a secondary outcome. These parameters were evaluated immediately after TPI. The primary outcome was evaluated using analysis of covariance and secondary outcome using the Mann-Whitney U test. Results VAS scores for pain during TPI were significantly lower in the vibration group (30.30; 95% confidence interval [CI], 22.65-39.26) compared with the control group (47.58; 95% CI, 38.80-56.52; F=7.74; P Conclusion Topical vibratory stimulation significantly decreased pain during TPI of the gastrocnemius. |
