Concussion is a common injury occurring in children and adolescent. In concussion, the brain is injured resulting in a wide variety of effects across physical, cognitive (thinking), psychological/behavioural, or sleep.

While most cases of concussion improve within weeks, approximately one third of children have on-going systems for greater than 1 month known as persistent post concussive symptoms (PPCS).

PPCS can impact the quality of life by effecting school performance, loss of peer contact, and removal from sports competitions.

The goal of the 5P study was to derive and validate easy to use prognosticators for clinicians to identify children and youth for risk of PPCS.
