The Efficacy of Repetitive Transcranial Magnetic Stimulation (rTMS) versus Transcranial Direct-Current Stimulation (tDCS) on Migraine Headaches: A Randomized Clinical Trial
Abstract
Abstract Background: Non-pharmacologic prophylactic methods for chronic migraine have been developed, including the promising non-invasive techniques of repetitive transcranial magnetic stimulation (rTMS) and transcranial direct-current stimulation (tDCS). This study aimed to compare the efficacy of rTMS and tDCS on pain intensity, the impact of headaches on daily life, anxiety, and depression in migraine headaches patients. Materials and Methods: This randomized clinical trial was conducted on 72 patients with migraine headaches, randomly allocated to the rTMS and tDCS groups. Participants received 3 and 12 sessions of stimulation over the left dorsolateral prefrontal cortex (DLPFC), respectively. Follow-up measurements, including pain intensity, anxiety, depression, and impact on daily life, were performed one month after the last sessions. Analyses were done by IBM SPSS statistics version 26 software. Results: Of 72 patients enrolled in the study, 19 were male (8 in the rTMS group and 11 in the tDCS group). There was no significant difference in baseline characteristics between groups. During the follow-up visit, both groups showed a decrease in anxiety levels (P values = 0.005 and 0.015), while only the rTMS group displayed a significant improvement in depression (P value = 0.01). However, no statistically significant difference was found among the groups regarding changes in pain intensity, anxiety, and the impact of headaches on daily life (P values >0.05). Conclusion:…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 72 participants or records.
