简要总结
To investigate the effectiveness of mechanism-based cervical sensorimotor rehabilitation on cervical muscle activation, cervical proprioception, and migraine burden.
详细描述
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.

研究组 & 干预措施
control group
The control group will receive conventional physiotherapy, including cervical range of motion exercises, stretching exercises, postural education, and a home exercise programme, with the same treatment frequency and duration as the experimental group.
干预措施: conventional physiotherapy programme (Other)
expermintal
he experimental group will receive an eight-week mechanism-based cervical sensorimotor rehabilitation programme consisting of deep cervical flexor training, cervical motor control exercises, laser-guided cervical joint position error retraining, eye-head coordination exercises, scapular neuromuscular stabilization exercises, and a structured home exercise programme. Treatment will be delivered three sessions per week, with each session lasting approximately 40 minutes.

结局指标
主要结局
cervical joint position error
时间窗: after the 8-week intervention, and at the 3-month follow-up
Cervical Joint Position Error (JPE) will be assessed to evaluate cervical proprioception using the Head Repositioning Accuracy Test. A lightweight laser pointer will be securely attached to the participant's head using an adjustable headband. Participants will be seated comfortably at a distance of 90 cm from a target grid mounted on a wall at eye level. At the beginning of each trial, participants will be instructed to identify and memorise their neutral head position while visually focusing on the centre of the target. They will then close their eyes and actively move their head to the end range of the required movement (flexion, extension, right rotation, left rotation, right lateral flexion, or left lateral flexion, depending on the testing protocol) before attempting to return to the original neutral position without visual feedback.The distance between the original target position and the repositioned laser point will be recorded and converted into angular error (degrees).
