King JA, et al. - Researchers examined patients presenting to a level I trauma center emergency department (ED) with mild traumatic brain injury (mTBI) for the frequency of neck pain overall and relative to other symptoms. In addition, they sought the predictors of primary neck pain in this population. Sport Concussion Assessment Tool 3 symptom questionnaire was used to assess the frequency of self-reported neck pain. Within 72 hours and at 8, 15, and 45 days, the frequency of any reported neck pain was 68.4%, 50.6%, 49%, and 41.9%, respectively, and the frequency of primary neck pain (equal or worse/worse definitions) was 35.8%/17.9%, 34.9%/14.5%, 37%/14.8%, and 39.2%/10.8%, respectively. Observations thereby suggest that neck pain is experienced by a sizable percentage of patients who present to level I trauma center EDs with mTBI. The neck pain is commonly rated as similar to or worse than other mTBI-related symptoms. Following motor vehicle collisions vs other mechanisms of injury, they encountered primary neck pain more commonly. These findings are in line with consensus statements classifying a cervical injury as an important potential concurrent diagnosis in patients with mTBI.
