Post‑concussion movement study
A PubMed analysis from the PedCARE cohort used compositional analysis to identify optimal movement behaviors for pediatric concussion recovery, highlighting specific activity/ rest balances clinicians should note during rehab reported. Those movement‑pattern insights give clinicians actionable targets for return‑to‑play progression in kids.
Analyses included 259 participants (mean age 13.3 years, 45% female) (bjsm.bmj.com) in the PedCARE secondary analysis. Movement behaviours were quantified with wrist/waist accelerometers over a 13‑day monitoring window and concussion symptoms were measured with the Health and Behaviour Inventory at a two‑week follow‑up (bjsm.bmj.com). On day 2 after presentation, the modelled optimal pattern featured 11.5 hours/day of sleep (≈690 minutes) and 8.5 hours/day sedentary time (510 minutes) versus cohort average (bjsm.bmj.com). Moderate‑to‑vigorous physical activity (MVPA) that tracked with better outcomes was quantified as ~0.6 h/day (36 minutes) on day 2, 1.5 h/day (90 minutes) on day 7, and 1.1 h/day (66 minutes) on day 13 in the compositional models (bjsm.bmj.com). Light physical activity emerged as increasingly optimal later in recovery, peaking around 5.5 hours/day (330 minutes) by day 10 in the predicted optimal compositions (bjsm.bmj.com). The PedCARE parent trial that generated the cohort is registered as NCT02893969 and tested early reintroduction of non‑contact activity (from ~72 hours post‑injury) versus usual care, providing the trial framework for this accelerometer subanalysis (clinicaltrials.gov).
