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

The goal of this single-case experimental study is to investigate the effects of intramuscular electrical stimulation for the treatment of trigger points on reducing the frequency of headaches in a small sample of patients with chronic migraine. Additionally, this study seeks to investigate the effects of intramuscular electrical stimulation to trigger points on reducing the overall headache intensity, impact and disability using research validated questionnaires.Intramuscular electrical stimulation is a treatment that uses needles to deliver electrical current into muscles, or trigger points, for reducing pain and improving function. Trigger points are painful spots within taut bands of muscle that produce pain when pressure is applied or spontaneously. Participants will be included if they have at least a 6-month history of chronic migraine headache. Due to the nature of the single case experimental design study, participants will each serve as their own controls and be randomized to various baseline measures where they will record headaches and symptoms using an electronic headache diary. During the intervention phase, participants will receive dry needling treatment with intramuscular electrical stimulation, and will continue recording in the electronic headache diary and complete all self reported outcome measures at the final treatment session.
