Undiagnosed concussions increase risk of additional injuries and can prolong recovery. Because of the difficulties recognizing concussive symptoms, concussion education must specifically target improving athlete concussion reporting. Many concussion education programs are designed without significant input from athletes, resulting in a less enjoyable athlete experience, with potential implications on program efficacy. Athlete enjoyment of previous concussion education programs moderates the improvement in concussion-reporting intention after experiencing the research version of CrashCourse (CC) concussion education. Prospective cohort study. Level of evidence: Level IV. Quantitative assessment utilizing ANOVA with moderation analysis of 173 male high school football players, aged 13 to 17, who completed baseline assessments of concussion knowledge, concussion reporting, and attitudes about prior educational interventions. Athletes were subsequently shown CC, before a follow-up assessment was administered assessing the same domains. At baseline, only 58.5% of athletes reported that they enjoyed their previous concussion education. After CC, athletes were significantly more likely to endorse that they would report a suspected concussion (from 69.3% of athletes to 85.6%; P < .01). Enjoyment of previous concussion education moderated concussion-reporting intention after CC (P = .02), with CC having a greater effect on concussion-reporting intention in athletes with low enjoyment of previous concussion education (b = 0.21, P = .02), than on individuals with high enjoyment of previous concussion education (P = .99). Enjoyment of CC did not have a moderating effect on concussion-reporting intention. Athletes who previously did not enjoy concussion education exhibited greater gains in concussion-reporting intention than athletes who enjoyed previous education. Given the potential risks associated with undiagnosed concussions, concussion education has sought to improve concussion reporting. Because most athletes participate in concussion education programs due to league or state mandates, improving concussion-reporting intention in these low-enjoyment athletes is of particular relevance to improving concussion-reporting intention broadly.

Randomized Controlled Trial Evaluating Aerobic Training and Common Sport-Related Concussion Outcomes in Healthy Participants.
(Journal of athletic training, 2018-12-18) Teel, Elizabeth F; Register-Mihalik, Johna K; Appelbaum, Lawrence Gregory; Battaglini, Claudio L; Carneiro, Kevin A; Guskiewicz, Kevin M; Marshall, Stephen W; Mihalik, Jason P
CONTEXT:Aerobic exercise interventions are increasingly being prescribed for concussion rehabilitation, but whether aerobic training protocols influence clinical concussion diagnosis and management assessments is unknown. OBJECTIVE:To investigate the effects of a brief aerobic exercise intervention on clinical concussion outcomes in healthy, active participants. DESIGN:Randomized controlled clinical trial. SETTING:Laboratory. PATIENTS OR OTHER PARTICIPANTS:Healthy (uninjured) participants (n = 40) who exercised ≥3 times/week. INTERVENTION(S):Participants were randomized into the acute concussion therapy intervention (ACTIVE) training or nontraining group. All participants completed symptom, cognitive, balance, and vision assessments during 2 test sessions approximately 14 days apart. Participants randomized to ACTIVE training completed six 30-minute exercise sessions that progressed from 60% to 80% of individualized maximal oxygen consumption (V˙o2max) across test sessions, while the nontraining group received no intervention. MAIN OUTCOME MEASURE(S):The CNS Vital Signs standardized scores, Vestibular/Ocular Motor Screening near-point convergence distance (cm), and Graded Symptom Checklist, Balance Error Scoring System, and Standardized Assessment of Concussion total scores. RESULTS:An interaction effect was found for total symptom score ( P = .01); the intervention group had improved symptom scores between sessions (session 1: 5.1 ± 5.8; session 2: 1.9 ± 3.6). Cognitive flexibility, executive functioning, reasoning, and total symptom score outcomes were better but composite memory, verbal memory, and near-point convergence distance scores were worse at the second session (all P values < .05). However, few changes exceeded the 80% reliable change indices calculated for this study, and effect sizes were generally small to negligible. CONCLUSIONS:A brief aerobic training protocol had few meaningful effects on clinical concussion assessment in healthy participants, suggesting that current concussion-diagnostic and -assessment tools remain clinically stable in response to aerobic exercise training. This provides normative data for future researchers, who should further evaluate the effect of ACTIVE training on clinical outcomes among concussed populations.

Return to sport after open and microdiscectomy surgery versus conservative treatment for lumbar disc herniation: a systematic review with meta-analysis.
(Br J Sports Med, 2016-02) Reiman, Michael P; Sylvain, Jonathan; Loudon, Janice K; Goode, Adam
BACKGROUND: Lumbar disc herniation has a prevalence of up to 58% in the athletic population. Lumbar discectomy is a common surgical procedure to alleviate pain and disability in athletes. We systematically reviewed the current clinical evidence regarding athlete return to sport (RTS) following lumbar discectomy compared to conservative treatment. METHODS: A computer-assisted literature search of MEDLINE, CINAHL, Web of Science, PEDro, OVID and PubMed databases (from inception to August 2015) was utilised using keywords related to lumbar disc herniation and surgery. The design of this systematic review was developed using the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Methodological quality of individual studies was assessed using the Downs and Black scale (0-16 points). RESULTS: The search strategy revealed 14 articles. Downs and Black quality scores were generally low with no articles in this review earning a high-quality rating, only 5 articles earning a moderate quality rating and 9 of the 14 articles earning a low-quality rating. The pooled RTS for surgical intervention of all included studies was 81% (95% CI 76% to 86%) with significant heterogeneity (I(2)=63.4%, p<0.001) although pooled estimates report only 59% RTS at same level. Pooled analysis showed no difference in RTS rate between surgical (84% (95% CI 77% to 90%)) and conservative intervention (76% (95% CI 56% to 92%); p=0.33). CONCLUSIONS: Studies comparing surgical versus conservative treatment found no significant difference between groups regarding RTS. Not all athletes that RTS return at the level of participation they performed at prior to surgery. Owing to the heterogeneity and low methodological quality of included studies, rates of RTS cannot be accurately determined.
