Evolution of dizziness-related disability in children following concussion: a group-based trajectory analysis.

This study aimed to identify Dizziness-Related Disability (DRD) recovery trajectories in pediatric concussion and assess clinical predictors of disability groups. In this prospective cohort study, 81 children (8-17 years) diagnosed with an acute concussion took part in 3 evaluation sessions (baseline, 3-month, and 6-month). All sessions included the primary disability outcome, the Dizziness Handicap Inventory (DHI) to create the DRD recovery trajectories using group-based multi-trajectory modeling analysis. Each independent variable included general patients' characteristics, premorbid conditions, function and symptoms questionnaires, and clinical physical measures; and were compared between the trajectories with logistic regression models. Low DRD (LD) trajectory ( Neck pain, premorbid anxiety, and the 5P score should be considered initially in clinical practice as to predict DRD at 3 and 6-month. Further research is needed to refine predictions and enhance personalized treatment strategies for pediatric concussion.
