Mechanism-Based Cervical Rehabilitation for Chronic Migraine

Chronic migraine is a disabling neurological disorder characterised by headache occurring on at least 15 days per month for more than three months, with migraine features on at least eight days per month according to the International Classification of Headache Disorders (ICHD-3). In addition to headache symptoms, individuals with chronic migraine frequently exhibit cervical musculoskeletal impairments, including reduced cervical range of motion, impaired cervical proprioception, altered neuromuscular control, and increased activity of superficial cervical muscles. These impairments are thought to be associated with altered sensorimotor integration and dysfunction of the trigeminocervical complex, potentially contributing to headache persistence and disability. Although several studies have reported beneficial effects of cervical rehabilitation in patients with migraine, the underlying neuromuscular mechanisms remain insufficiently understood. In particular, few randomized controlled trials have simultaneously investigated changes in cervical muscle activation, cervical joint position error, and migraine-related outcomes following a structured cervical sensorimotor rehabilitation programme. Understanding these mechanisms may improve clinical decision-making and facilitate the development of targeted rehabilitation strategies. This study is a prospective, assessor-blinded, parallel-group randomized controlled trial designed to investigate the effectiveness of a mechanism-based cervical sensorimotor rehabilitation programme in patients with chronic migraine. A total of 80 participants diagnosed with chronic migraine according to the International Classification of Headache Disorders, Third Edition (ICHD-3) will be recruited from the outpatient clinics of the Faculty of Physical Therapy, Beni-Suef University. Participants will be randomly allocated in a 1:1 ratio to either an experimental group or a control group using a computer-generated randomization sequence with concealed allocation.
