Neck pain associated with headache attributed to rhinosinusitis: an observational study.

Background: Neck pain is common among people with headache, including migraines, tension headache, and cervicogenic headache. Neck pain has also been associated with self-reported sinus headache in individuals who were not formally diagnosed with headache attributed to rhinosinusitis (HAR). Neck pain, in individuals diagnosed with HAR according to the International Classification of Headache Disorders, has not been investigated.

Objective: The primary objective of this study was to compare the report of neck pain in people with and without HAR. A secondary purpose was to compare measures of cervical musculoskeletal dysfunction between groups.

Methods: This was an observational study. There were 80 total participants, age and sex-matched with 40 per group. HAR group participants completed the Headache Impact Test, Sino-Nasal Outcome Test-22, Neck Disability Index (NDI), and Visual Analog Scale Score (VASS) to rate headache. All participants underwent examination of neck range of motion, neck muscle endurance, and segmental examination.

Results: There were significant between-group differences for reported neck pain (82.5% in HAR group; 22.5% in control group,  < .001) and NDI score (mean difference [95% CI] = 15.7 [11.1, 20.2],  < .001). There was a moderate and significant positive correlation between HAR and segmental dysfunction in the upper cervical spine (O-C3) (0.425,  < .001) but not the lower cervical spine.

Conclusion: Neck pain may be associated with HAR, and patients perceive this neck pain as impacting their quality of life. Upper cervical segmental dysfunction was common and significantly different in the HAR group. Causation of both the subjective and objective findings remains unclear.
