INTRODUCTION: Rest until symptom-free, followed by a progressive stepwise return to activities, is often prescribed in the management of paediatric concussions. Recent evidence suggests prolonged rest may hinder recovery, and early resumption of physical activity may be associated with more rapid recovery postconcussion. The primary objective is to determine whether the early reintroduction of non-contact physical activity beginning 72 hours postinjury reduces postconcussive symptoms at 2 weeks in children following an acute concussion as compared with a rest until asymptomatic protocol...

CONTEXT:   After a concussion or mild traumatic brain injury (mTBI), patients often suffer from light sensitivity, or photophobia, which contributes to decreased quality of life post-mTBI. Whereas sunglasses may provide some relief from photophobia, they are not practical indoors or in low light. A light-mitigation strategy can be easily used indoors as needed to optimize the relief. We have found that many photophobic patients experience relief using colored sunglasses. OBJECTIVE:   To provide the athletic trainer with a means and method to assess whether an athlete is suffering from photophobia after concussion and to determine if colored glasses provide relief...

Objective: Extant literature has demonstrated that symptoms of postconcussive syndrome (PCS) persist well beyond the expected 3-month post-injury recovery period in a minority of individuals with mild traumatic brain injury (mTBI). Suboptimal performance on validity measures and pre- and post-injury psychosocial stressors - rather than actual mTBI or current cognitive functioning - have been identified as predictors of chronic PCS. Whether premorbid IQ has any influence on chronic PCS has been understudied, in the context of established psychogenic etiologies...

Despite increasing injury prevalence of traumatic brain injury (TBI) in children, most injuries in children are mild in severity. Even mild injuries can result in long-term or chronic effects not apparent until the child ages, resulting in increased economic burden and overall lifetime costs related to injury. Early recognition of TBI is essential for ongoing evaluation and management of acute symptoms and reduction of chronic health effects. Providing early interventions to manage acute and postconcussive symptoms and reducing health disparities in children with mild TBI can minimize adverse events that impact health-related quality of life for the injured child and their family and increase overall population health...

BACKGROUND: The Balance Error Scoring System (BESS) shows that balance tends to recover within days after a concussion, whereas measures of the movement of the center of pressure (COP) show that balance deficits can persist up to 1 month after concussion. While approximately 30% of adolescents suffering concussion have functional consequences including balance deficits, evidence of the use of different balance assessments for concussion is limited within this population. PURPOSE: To compare performance on a series of balance assessments between adolescents with a diagnosed concussion at 1 month postinjury and noninjured control participants within the same age distribution...
