OBJECTIVES/GOALS: Evidence suggests that individuals with generalized joint hypermobility (GJH), or excessive joint range of motion, are at higher risk of developing chronic neck pain. The objective of this study is to determine the prevalence and clinical presentation of chronic neck pain in GJH and investigate its associations with other measures of spine health. METHODS/STUDY POPULATION: Data was collected at the Driven to Discover Research Facility at the 2022 Minnesota State Fair. Individuals 18 years and older were invited to participate. All enrolled participants completed Phase 1, which included: the Beighton Score (measure of GJH), the 5-Point-Questionnaire (self-report survey for current or historical GJH), and a custom self-report survey for demographics and musculoskeletal pain. A subset of participants was also asked to complete Phase 2 of the study. Phase 2 consisted of additional self-report surveys (Neck Disability Index (NDI) and PROMIS-10 Global) and the following physical measures: neck range of motion in all planes, neck strength in flexion-extension and lateral bending, and grip strength. RESULTS/ANTICIPATED RESULTS: A total of 559 participants were enrolled in the study. All participants completed Phase 1, and 285 of those individuals completed Phase 2. Those with a Beighton Score≥4 were categorized as having GJH. The overall prevalence of GJH was 23.8% for females and 9.1% for males. Consistent with previous studies, multiple linear regression analysis (R2=0.20, F(2,552) = 69.37, p DISCUSSION/SIGNIFICANCE: This is one of the largest studies investigating GJH, pain, and physical measures of neck function in the general population. The results highlight the higher prevalence of chronic neck pain in those with GJH and will form the basis for a subsequent study to identify mechanisms and potential therapeutic targets for individuals with GJH and chronic pain.
