Comparative Effectiveness of Neuromuscular Electrical Stimulation Versus Isometric Exercises in Patients with Cervicogenic Headache: A Randomized Controlled Trial
Abstract: Background: Cervicogenic Headache (CGH) is a secondary headache disorder in which pain is referred from the cervical spine. It is characterized by unilateral headache, restricted cervical range of motion, and pain aggravated by neck movement or awkward posture. Dysfunction of the upper cervical joints (C0-C3), weakness of the Deep Neck Flexors (DNF), and tight cervical extensors are common causes. Isometric exercises are considered the gold standard for strengthening deep cervical flexors without excessive stress on cervical joints. These low-load endurance exercises restore normal muscle function. Neuromuscular Electrical Stimulation (NMES) uses electrical currents to produce muscle contractions. It is believed to re-educate weak muscles, reduce spasm in tight extensors such as the upper trapezius, and decrease pain through the Gate Control Theory. Aim: To compare the therapeutic efficacy of NMES and isometric exercises in managing Cervicogenic Headache. Objective: To compare the effects of neuromuscular electrical stimulation and isometric exercises on pain, disability, and cervical mobility in patients with cervicogenic headache. Methods: Forty-six participants with cervicogenic headache were allocated into two groups. One group received NMES, while the other performed supervised isometric cervical exercises. Outcomes included Numeric Pain Rating Scale, Neck Disability Index, and Cervical Flexion Rotation Test before and after intervention. Results: Both groups improved significantly. The NMES group demonstrated greater reductions in pain and disability, while between-group differences in cervical mobility was not statistically significant. Conclusion: Both interventions were beneficial; NMES showed superior improvement in selected outcomes within study limitations.
