Use of supervised exercise during recovery following sports-related concussion.

Objective: To assess the safety of supervised exercise (SE) in acute sport-related concussion (SRC) and its influence on recovery. Design: Retrospective cohort study. Setting: University SRC clinic at a tertiary care center. Patients: One hundred ninety-four consecutive new patient charts were reviewed. Patients were included if they were seen within 30 days of sustaining a SRC, and their medical records included all required data elements. One hundred twenty-six patients were included in the analysis. Interventions: Symptomatic patients who initiated SE within 16 days of SRC (n = 24) were compared with those who did not undergo SE or initiated SE after postinjury day 16 (n = 84). Age, sex, history of previous concussions, injury severity, relevant comorbidities, and other treatments received were included in the analysis. Main Outcome Measures: The association between early SE and clearance for return to sport was determined using a hazard ratio (HR). The number of days from SRC until clearance for return to sport and the number of days symptomatic from concussion were also compared between early SE and nonearly SE cohorts. Results: No serious adverse events occurred in the early SE group. Early SE was associated with earlier return to sport (HR = 2.35, P = 0.030). The early SE group had fewer days from SRC until clearance for return to sport (mean 26.5 ± 11.2 days vs 35.1 ± 26.5 days, P = 0.020). There was a trend toward fewer symptomatic days in the early SE group (P = 0.054). Conclusion: Early SE performed in the symptomatic stage of SRC was safe and associated with earlier return to sport.http://deepblue.lib.umich.edu/bitstream/2027.42/175856/2/Use of Supervised Exercise During Recovery Followng Sports Related Concussion.pdfPublished versionDescription of Use of Supervised Exercise During Recovery Followng Sports Related Concussion.pdf : Published versio

Post-traumatic Dizziness

Mild traumatic brain injury (mTBI) is an increasingly common disorder seen in particular situations (athletics, military service, etc.) and in the general population. This disorder is largely synonymous with concussion and is associated with a variety of acute, subacute, and even chronic consequences. One of the most common sequelae of mTBI (at any time epoch) is dizziness. In this chapter, we explore the nature of post-traumatic dizziness and provide an introduction into the related topics of diagnosis and treatment of mTBI
