Cervicogenic Headache
Conditions
Brief summary
This research study aims to better understand the relationships between neck muscle function, neck joint position sense, and headache pain and disability in people with chronic cervicogenic headache. Cervicogenic headache is headache originating from the neck area. Participants will fill out questionnaires about their headache pain and ability to do daily activities. They will also do tests to measure neck muscle fatigue and neck joint position sense. Researchers will analyze if those with more neck muscle fatigue and poorer joint position sense have worse headache pain and disability. The results may improve understanding of cervical spine factors related to cervicogenic headache. This could help guide more targeted treatment approaches.
Detailed description
Chronic cervicogenic headache (CGH) is characterized by chronic headache originating from the upper cervical spine and occipital region. CGH is associated with impairments in cervical muscular control and proprioception or joint position sense. However, relationships between these cervical impairments and headache symptoms are not fully elucidated. This cross-sectional quantitative study aims to investigate associations between neck flexor muscle fatigue, cervical joint position sense, and clinical headache parameters like pain and disability in individuals with CGH. A sample of 30 adults ages 18-65 years old with CGH longer than 3 months duration and more than 15 headache days per month will be recruited from neurology clinics. Participants will attend a single 2 hour study visit.
Interventions
DIAGNOSTIC_TESTQuantitative Sensory and Neurophysiological Testing
Participants will undergo the following quantitative sensory and neurophysiological diagnostic tests: Surface electromyography (EMG) of the neck flexor muscles during the craniocervical flexion test to assess neck flexor muscle fatigue. EMG sensors will be placed over the sternocleidomastoid and longus colli muscles. Cervical joint position error testing to evaluate proprioceptive awareness and cervicocephalic kinesthetic sensibility. Participants will be seated upright and blindfolded.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Headache Pain Intensity | Baseline | Average headache pain over the past week rated on a 0-10 Numerical Rating Scale (NRS). Participants asked to rate their average pain level over the past week on a 0 to 10 scale, where 0 is no pain and 10 is the worst possible pain. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Headache Disability | Baseline | Total score on the 25-item Headache Disability Inventory (HDI) questionnaire, assessing headache-related disability over the past month. Each item scored as yes (4 points), sometimes (2 points), or no (0 points). Total score ranges from 0 to 100, with higher scores indicating greater disability. |
| Neck Flexor Fatigue | baseline | Change in mean surface electromyography (EMG) amplitude (measured in microvolts) of the sternocleidomastoid and longus colli muscles from start to end of a 30-second craniocervical flexion contraction at 50% maximum voluntary contraction (MVC). |
| Cervical Joint Position Sense | Baseline | Absolute error in degrees between perceived and actual head repositioning after returning from 20 degrees of active right cervical rotation. Average error over 3 trials used. |
