- Patients with migraines treated with repetitive peripheral magnetic stimulation (rPMS) report improvements in local muscular pain.
Why this matters
- rPMS applied to trapezius muscles, which are part of the trigeminocervical complex (TCC), was not only associated with symptom relief but also could elucidate the relationship between skeletal musculature and migraine.
- Patients (migraine; N=37) were randomly assigned to receive rPMS either on the trapezius muscles (n=19) or the deltoid muscles (n=18) for 2 weeks.
- Funding: None disclosed.
- All patients showed at least 1 active myofascial trigger point (mTrP; trapezius muscles) and 1 latent mTrP (the deltoid muscles).
- A total of 222 stimulation sessions including 114 stimulation sessions in trapezius and 108 stimulation sessions in the deltoid group were conducted.
- No adverse events occurred, and there were no dropouts during the 2 weeks of rPMS.
- rPMS was comfortable for 84.2% in the trapezius group and 94.4% in the deltoid group (not significant; P=.736).
- Improved muscular pain/tension was reported in 73.7% of the trapezius group and 61.1% of the deltoid group (not significant; P=.077).
- The study was single center, included very few patients, and did not assess placebo or setting effects on pressure pain thresholds.
