Migraine without aura is a highly prevalent and disabling primary headache that significantly affects quality of life. Many patients experience insufficient symptom control with pharmacological treatments or develop adverse effects, which has increased interest in safe, non-invasive therapeutic alternatives. Physiotherapy, and particularly manual therapy, has shown potential benefits in reducing pain and improving function in headache disorders. This randomized clinical trial will evaluate the effectiveness of adding specific myotensive techniques directed at the extraocular muscles to a craniocervical manual therapy program in adults with migraine without aura. The hypothesis is that targeting the oculomotor system may influence pain modulation and improve symptoms related to visual, cervical, and sensorimotor interactions.
Ninety participants aged 18 to 65 years with a medical diagnosis of migraine without aura according to the International Classification of Headache Disorders, Third Edition (ICHD-III), will be randomly assigned to an experimental group or a control group. Both groups will receive six physiotherapy sessions over approximately eight weeks. The experimental group will receive manual therapy on the craniocervical region and temporomandibular joint (TMJ) combined with myotensive techniques for the extraocular muscles, while the control group will receive only the standard manual therapy protocol. Evaluations will be conducted at baseline and post-intervention using validated instruments such as the Migraine Disability Assessment (MIDAS), Craniofacial Pain and Disability Inventory (CF-PDI), Migraine-Specific Quality of Life Questionnaire (MSQ), and Visual Analogue Scale (VAS) for pain. Cervical mobility and oculomotor function will also be assessed through standardized clinical tests.
All procedures will be carried out at the Faculty of Nursing, Physiotherapy and Podiatry of the University of Seville. Data will be collected and managed in digital format in compliance with the General Data Protection Regulation (GDPR) and Spanish data protection law. Study results are expected to clarify the role of the oculomotor system in migraine without aura and to determine whether incorporating extraocular myotensive techniques enhances the effects of manual therapy within a comprehensive physiotherapeutic approach.
