Feasibility of Concussion Essentials: A multimodal intervention for persisting post-concussion symptoms among children and adolescents.

ABSTRACT

This study examined the feasibility of "Concussion Essentials" (CE), an individualized, multimodal intervention for persisting post-concussion symptoms (pPCS). Thirteen 6-18 year-olds with pPCS at 1-month post-concussion, as determined by the Post Concussion Symptom Inventory - Parent Report (PCSI-P), completed education, physiotherapy, and psychology modules, for up to 8-weeks or until pPCS resolved. Intervention participants were matched to a longitudinal observational cohort who received usual care (n = 13). The study enrolled 70% of participants symptomatic on screening and the dropout rate was <30% between baseline and post-programme assessments (4-weeks to 3-months post-injury). Symptoms improved for 100% of CE participants, with the number of symptomatic items on the PCSI-P reducing from 4-weeks, Median (IQR) = 14.0 (8.0-19.0) to 3-months, Median (IQR) = 1.0 (0.0-5.0). Comparatively, symptoms improved for approximately half of matched usual care participants. CE participants (n = 8) and their parents (n = 11) completed acceptability questionnaires. Most parents (91%) agreed CE was acceptable for children with concussion. All participants agreed CE was appropriate for concussion, while approximately 88% agreed they enjoyed the intervention and would recommend CE to others. Findings suggest CE is a feasible and acceptable treatment for paediatric pPCS. Further investigation within a larger scale randomized clinical trial is warranted.
