Neck pain is the second most common musculoskeletal disorder in population surveys and is associated with high injury and disability claims. 1,2 It is generally accepted that neck pain has a favorable course of care, 3 but there is variation in short-term outcomes in patients with neck pain. 3,4 Certain factors are known to be prognostic for the course of neck pain, and several interventions, including those provided by physical therapists, are likely to produce a favorable outcome. [5][6][7][8][9] Approximately 35% of persons with neck pain reported being seen by a physical therapist, the most frequently visited provider, 10 and evidence suggests that physical therapy can be an effective secondary prevention strategy for neck pain. 11 In recent years, organized efforts have been made to improve clinical outcomes and standardize physical therapy treatment, including using classification system approaches. Fritz and Brennan 12 supported that subgrouping patients with neck pain and providing interventions matched to the patient classification improves shortterm outcomes of pain and disability from physical therapy, but this approach has not been validated nor have other classification systems published in the literature been validated. 13,14 Therefore in this study, rather than introduce a new classification system, we wished to pragmatically examine a large cohort of patients with common clinical presentations of neck pain. The purposes of this study were to describe the demographics and Disclosures: none.
