eck-specific strengthening exercise compared with placebo sham ultrasound in patients with migraine: two-armed, parallel-groups randomized controlled trial.

After eight weeks of treatment, no differences were observed in the group-by-time interaction for the primary outcomes (p>0.05). Thus, we concluded that localized craniocervical exercises were insufficient in reducing the frequency and intensity of migraine attacks, improving the performance of the cervical muscles, or reducing migraine and neck pain-related disabilities.
