Predictors of pain persistence and disability in high-school students with chronic neck pain at 6-month follow-up.

Abstract

Neck pain tends to persist for periods of 1 to 4years of follow-up in adolescents, and a high percentage of them report disability. However, studies assessing the factors associated with persistent neck pain and disability in this age group are scarce. This study aimed to explore the association between psychosocial factors, sleep, and symptoms of central sensitization at baseline and the persistence of neck pain and disability at 6-month follow-up. A total of 710 adolescents with chronic neck pain were assessed at baseline with an online questionnaire that collected information on sociodemographic data, presence of musculoskeletal pain, pain intensity, physical activity, functional disability, depression, anxiety, stress, quality of sleep, catastrophizing, kinesiophobia, self-efficacy, and symptoms of central sensitization. At 6-month follow-up, adolescents were reassessed for disability and pain intensity and categorized as recovered or reporting persistent neck pain. Of the 710 participants with neck pain at baseline, 334 were classified as having persistent neck pain and 375 adolescents as being recovered at 6-month follow-up. Multivariable analysis showed that female gender (OR 1.47; p = 0.04) and symptoms of central sensitization (OR 1.02; p = 0.001) at baseline were positively associated with the persistence of neck pain at 6-month follow-up. Similarly, higher levels of disability (β = 0.41; p < 0.001) and symptoms of central sensitization (β = 0.28; p < 0.001) at the baseline were positively associated with disability. Symptoms of central sensitization and disability at baseline should be considered in the assessment and design of interventions for adolescents with chronic neck pain as an attempt to minimize its future impact on pain persistence and disability.
