Brain Network Activation Technology Does Not Assist with Concussion Diagnosis and Return to Play in Football Athletes.

ABSTRACT:

Background

Concussion diagnosis and management remains a largely subjective process. This investigation sought to evaluate the utility of a novel neuroelectric measure for concussion diagnosis and return to play decision-making.

Hypothesis

Brain Network Activation (BNA) scores obtained within 72-h of injury will be lower than the athlete's preseason evaluation and that of a matched control athlete; and the BNA will demonstrate ongoing declines at the return to play and post-season time points, while standard measures will have returned to pre-injury and control athlete levels.

Design

Case-control study.

Methods

Football athletes with a diagnosed concussion (n?=?8) and matched control football athletes (n?=?8) completed a preseason evaluation of cognitive (i.e., Cogstate Computerized Cognitive Assessment Tool) and neuroelectric function (i.e., BNA), clinical reaction time, SCAT3 self-reported symptoms, and quality of life (i.e., Health Behavior Inventory and Satisfaction with Life Scale). Following a diagnosed concussion, injured and control athletes completed post-injury evaluations within 72-h, once asymptomatic, and at the conclusion of the football season.

Results

Case analysis of the neuroelectric assessment failed to provide improved diagnostics beyond traditional clinical measures. Statistical analyses indicated significant BNA improvements in the concussed and control groups from baseline to the asymptomatic timepoint.

Conclusion

With additional attention being placed on rapid and accurate concussion diagnostics and return to play decision-making, the addition of a novel neuroelectric assessment does not appear to provide additional clinical benefit at this time. Clinicians should continue to follow the recommendations for the clinical management of concussion with the assessment of the symptom, cognitive, and motor control domains.

Project description:Study Design?Systematic review. Clinical Questions?Among athletes who undergo surgery of the cervical spine, (1) What proportion return to play (RTP) after their cervical surgery? (2) Does the proportion of those cleared for RTP depend on the type of surgical procedure (artificial disk replacement, fusion, nonfusion foraminotomies/laminoplasties), number of levels (1, 2, or more levels), or type of sport? (3) Among those who return to their presurgery sport, how long do they continue to play? (4) Among those who return to their presurgery sport, how does their postoperative performance compare with their preoperative performance? Objectives?To evaluate the extent and quality of published literature on the topic of return to competitive athletic completion after cervical spinal surgery. Methods?Electronic databases and reference lists of key articles published up to August 19, 2015, were searched to identify studies reporting the proportion of athletes who RTP after cervical spine surgery. Results?Nine observational, retrospective series consisting of 175 patients were included. Seven reported on professional athletes and two on recreational athletes. Seventy-five percent (76/102) of professional athletes returned to their respective sport following surgery for mostly cervical herniated disks. Seventy-six percent of recreational athletes (51/67) age 10 to 42 years RTP in a variety of sports following surgery for mostly herniated disks. No snowboarder returned to snowboarding (0/6) following surgery for cervical fractures. Most professional football players and baseball pitchers returned to their respective sport at their presurgery performance level. Conclusions?RTP decisions after cervical spine surgery remain controversial, and there is a paucity of existing literature on this topic. Successful return to competitive sports is well described after single-level anterior cervical diskectomy and fusion surgery for herniated disk. RTP outcomes involving other cervical spine diagnoses and surgical procedures remain unclear. Additional quality research is needed on this topic.

Project description:While awareness and understanding of concussion have improved drastically, post-concussion management in academic settings is still at its infancy. The aim of the study was to examine to what extent concussion influences academic performance and to whether there would be a difference in concussion effects on academic performance between high school and college students. This cross-sectional survey study included students, who were between 14 and 24 years old and sustained a sport-related concussion within the previous year. The study used a modified chain-referral sampling method, by distributing a questionnaire link to 3,000 randomly stratified athletic trainers, who worked in high school or college settings. These athletic trainers were then asked to forward the questionnaire link to students in their team, who have sustained a concussion within the previous year. The questionnaire recorded responses regarding demographics (age, sex, race/ethnicity, number of previous concussions); 22 concussion-related symptoms in a binary scale (presence/absence); perception of difficulties in math, reading, writing, computer use, and attention in a 5-point Likert scale; and asymptomatic duration of academic engagement in a 7-point Likert scale. There were 130 respondents with a history of concussion in the past year (n = 59 high school, n = 71 college). While recovering from concussion, significantly more college students (84.5%) reported "difficulty concentrating" than high school students (68.6%: p = 0.049). High -school students experienced more difficulty with math than college students (p = 0.002), whereas college students experienced more difficulty with reading (p = 0.013) and computer use (p = 0.026) than high school students. Asymptomatic duration of cognitive activity was influenced by age (p = 0.0004), where younger students were less tolerant in performing academic tasks after a concussion than older students. Our data indicate that concussions can induce negative symptoms in the academic setting regardless of age. The post-concussion difficulties in academic performance may be a grade-dependent manner, where concussions triggered difficulty in math among high school students and in reading and computer use among college students. It is clear that there is a need for guidelines and accommodations to support students with concussion in academic settings, and the guideline should reflect the age-dependent response to concussions.

Project description:BackgroundConsiderable variability exists in return-to-play rates after anterior cruciate ligament (ACL) injury and reconstruction (ACLR) among National Football League (NFL) players of different positions.Purpose/hypothesisThe purpose of this study was to compare return-to-play and performance levels by position in NFL players after ACLR. It was hypothesized that (1) ACL injuries have significant effects on the careers of NFL players, including return to play and performance, and (2) players of certain positions that involve relatively less pivoting and cutting perform better after ACLR.Study designDescriptive epidemiology study.MethodsAll NFL players who underwent ACLR between 2013 and 2018 were identified using the FantasyData injury database. Player characteristics, snap count, games played, games started, and performance metrics were collected for 3 years before and after injury using the Pro Football Reference database. Performance was measured using an approximate value (AV) algorithm to compare performance across positions and over time. Nonparametric tests were used to compare the pre- and postinjury data and the percentage change in performance between different positions.ResultsOverall, 312 NFL players were included in this study, and 174 (55.8%) returned to play. Of the eligible players, only 28.5% (n = 59/207) remained in the league 3 years postinjury. Within the first 3 years postinjury, players played in fewer games (8.7 vs 13.7; P < .0001), started in fewer games (3.0 vs 8.3; P < .0001), had lower AVs (1.5 vs 4.3; P < .0001), and had decreased snap counts (259.0 vs 619.0; P < .0001) compared with preinjury. Quarterbacks were most likely to return to play (92.9% vs 53.7%; P = .0040) and to return to performance (2% vs 50% decrease in AV; P = .0165) compared with the other positions. Running backs had the largest decrease in AV (90.5%), followed by defensive linemen (76.2%) and linebackers (62.5%).ConclusionThe study findings indicated that NFL players are severely affected by ACL injury, with only 28.5% still active in the league 3 years after the injury. Running backs, defensive linemen, and linebackers performed the worst after injury. Quarterbacks were most likely to return to play and had superior postinjury performance compared with the other positions.

Project description:ObjectiveTo examine the progression of collegiate student athletes through five stages of a return-to-activity protocol following sport-related concussion (SRC).MethodsIn a multisite prospective cohort study, we identified the frequency of initial 24-48 hours physical and cognitive rest, and the sequence of (1) symptom resolution and return to (2) exertion activity, (3) limited sport, (4) full sport and (5) full academics. In resulting profiles we estimated the likelihood of return to full sport ≤14 days or prolonged >28 days and tested for variability based on timing of the stages.ResultsAmong 1715 athletes with SRC (31.6% females), 67.9% had 24-48 hours initial physical and cognitive rest. The median was 6 days to return to full academics, 8 days to symptom resolution and 9 days to exertion. Three profiles emerged; all had the same sport-specific return progression, but varied in the relative timing of full academics. In unadjusted analyses, full academics as the first stage corresponded to the longest time to return to full sport, and initiating exertion the same day as symptom resolution resulted in the shortest time. In adjusted regression analyses, athletes initiating full academics while still symptomatic were 21.5% less likely (95% CI -27.4% to -15.5%) to return to full sport ≤14 days and, analogously, 19.1% more likely (95% CI 13.4% to 24.7%) to have prolonged return >28 days. While additionally controlling for initial rest, sex, symptom count and concussion history, the likelihood of prolonged return >28 days was 37.0% (95% CI 25.2% to 48.8%) in athletes initiating exertion considerably before symptoms resolved (ie, 7+ days), but only 3.6% (95% CI -1.4% to 8.6%) in athletes initiating exertion shortly before achieving symptom resolution (ie, 3-4 days).ConclusionWe found evidence that sequential progressions were consistent with current recommendations including brief initial rest, and the initiation and relative timing of each stage impacted the final return-to-sport outcome.
