Intramuscular Electrical Stimulation for the Treatment of Trigger Points in Patients With Migraine

Dry needling will be applied to trigger points in at least two of the following posterior cervical muscles; splenius capitis, splenius cervicis, semispinalis capitis/cervicis, cervical multifidi (from C2-4) and obliquus capitis inferior. Following elicitation of a local twitch response, needles will be left in place and connected to a charge generating device for intramuscular electrical stimulation.
