Randomized Controlled TrialImproving Concussion Reporting across National College Athletic Association Divisions Using a Theory-Based, Data-Driven, Multimedia Concussion Education Intervention.
Although a base level of knowledge is needed to recognize a concussion, knowledge-focused concussion educational materials ignore multifaceted barriers to concussion reporting. We compared student-athlete concussion reporting intentions and behaviors prior to and 1 year after exposure to an intervention or control treatment. We randomly assigned 891 collegiate student-athletes from three universities (Divisions I, II, III) to either the control group (National College Athletic Association [NCAA] Concussion Fact Sheet) or intervention group (theory-based, data-driven, multimedia, simulated concussion reporting module). ⋯ Relative to the control group, the intervention group had significantly greater odds of responding that the concussion education "greatly improved" rather than "did not improve" their knowledge (odds ratio [OR]: 2.49, 95% CI:1.25,4.96), attitudes (OR: 2.22, 95% CI: 1.23,4.03), self-efficacy (OR: 1.95,95% CI: 1.05,3.60), and intentions (OR: 1.86,95% CI: 1.03,3.35). The intervention was more effective at targeting elements of the overall sport culture in a way that substantively improved concussion reporting. We recommend use of this intervention in combination with other evidence-based educational materials.

Randomized Controlled TrialMusic Therapy Enhances Executive Functions and Prefrontal Structural Neuroplasticity after Traumatic Brain Injury: Evidence from a Randomized Controlled Trial.
Traumatic brain injury (TBI) causes lifelong cognitive deficits, particularly impairments of executive functioning (EF). Musical training and music-based rehabilitation have been shown to enhance cognitive functioning and neuroplasticity, but the potential rehabilitative effects of music in TBI are still largely unknown. The aim of the present crossover randomized controlled trial (RCT) was to determine the clinical efficacy of music therapy on cognitive functioning in TBI and to explore its neural basis. ⋯ Results showed that general EF (as indicated by the Frontal Assessment Battery [FAB]) and set shifting improved more in the AB group than in the BA group over the first 3-month period and the effect on general EF was maintained in the 6-month follow-up. Voxel-based morphometry (VBM) analysis of the structural MRI data indicated that gray matter volume (GMV) in the right inferior frontal gyrus (IFG) increased significantly in both groups during the intervention versus control period, which also correlated with cognitive improvement in set shifting. These findings suggest that neurological music therapy enhances EF and induces fine-grained neuroanatomical changes in prefrontal areas.
