“…21 Results indicated that previously concussed athletes demonstrated altered collision avoidance behaviors, even after receiving medical clearance to RTS. 21 Taken a step further, it is possible that the concussed athletes' poor performances during the walking task could have resulted from feeling they were underprepared (or not ready) to resume sport participation, despite progressing through the current RTS strategy. Given that the healthcare professionals in our study, who, on average, had 10 years of experience working with concussed athletes, indicated that behavioral factors are a consideration when returning athletes to sport after SRC, more research seems warranted to understand how to facilitate behavioral preparedness.…”

“…3 Our findings mirrored previous research, 20 whereby participants discussed instances where athletes malingered (defined as prolonging their absence from sport), a greater number of participants highlighted occasions when athletes changed their behaviors when returning to sport in the form of avoiding contact/ collision (eg, with opponents), or by playing more passively on RTS. 10,21 One recent study investigated whether a group of previously concussed athletes exhibited collision avoidance behaviors during a laboratory walking task when compared with nonconcussed athletes. 21 Results indicated that previously concussed athletes demonstrated altered collision avoidance behaviors, even after receiving medical clearance to RTS.…”

Objective: To explore the factors involved in athletes being ready (or not) to return to sport (RTS) after sport-related concussion (SRC). Design: Qualitative, semistructured interviews. Setting: Videoconference. Participants: Twenty-two sport-injury stakeholders involved in contact and collision sports at various levels of competition (high school, university, professional), including: formerly concussed athletes (n = 4), coaches (n = 5), athletic therapists (n = 5), physiotherapists (n = 4), nurse practitioner (n = 1), and sports medicine physicians (n = 3). Interventions: N/A. Main Outcome Measures: We included questions in the interview guide regarding factors participants believed were involved in athletes being ready (or not ready) to RTS after a concussion. Results: Participants described physical (concussion symptoms, return to pre-injury fitness), behavioral (changes in behavior, avoidance, malingering), psychological (individual factors, cognitive appraisals, mental health), and social (isolation, social support, communication, pressure) factors that they believed were involved in athletes being ready to RTS after SRC. Conclusions: The graduated RTS strategy outlined in the most recent Concussion in Sport Group consensus statement focuses on physical aspects involved in being ready to RTS, which does not address behavioral, psychological, and social factors, which were identified by participants as being related to returning to sport post-SRC. More research is needed to determine whether the additional factors outlined in this study are relevant among larger samples of athletes, coaches, and healthcare professionals.

“…Collision risk is a key variable, so it is interesting that the concussion group had a similar number of total collisions to the control group, given that concussion leads to well-documented impairments in key cognitive and motor functions required for driving. 13,17,24 We observed other driving behaviors consistent with increased likelihood of motor vehicle crash (e.g. greater SDLP, more lane excursions), but further research is needed to determine whether on-road collision risk is elevated after concussion.…”

“…Previous studies examining overground walking showed that athletes with a history of concussion responded at a delay to avoid a walking collision. 17,24 Temporal outcomes that reflect successful collision avoidance, such as reaction time or time to collision, may be more sensitive to more subtle impairment levels. 13,17,24 Given the differences noted between our previous work and the present study, future studies should consider drive duration and driving endurance during assessment.…”

Longitudinal Assessment of Postconcussion Driving: Evidence of Acute Driving Impairment

Background: Current medical practices and recommendations largely ignore the safety of postconcussion driving, even though commonly used measures of neurocognition, balance, and vestibulo-ocular function show impairment. Purpose: To compare simulated driving between patients with concussion and controls throughout concussion recovery using a case-control design. Study Design: Cohort study; Level of evidence, 2. Methods: A total of 26 concussed and 23 control Division I collegiate athletes completed a driving simulation assessment at 3 time points (within 72 hours, asymptomatic, and return to sport). Cumulative driving simulation outcome variables included total number of collisions, speed exceedances, stop signs missed, lane excursions, total drive time, percentage of time over the speed limit, and percentage of time out of the lane. The mean speed, standard deviation of speed (SDS), lateral lane position, and standard deviation of lateral lane position (SDLP) were examined for each of the 11 drive segments. Outcomes were compared using generalized linear mixed models with random intercepts by participant with Poisson or normal distributions. Results: Within 72 hours of injury, the concussion group committed more lane excursions (median difference, 2; P = .003), exhibited greater SDS while avoiding a child pedestrian crossing the road (Cohen d = 0.73; P = .011), drove ~7 inches (~18 cm) closer to the centerline during a residential left curve ( d = 0.90; P = .015), and had greater SDLP while navigating around a car crash compared with controls ( d = 0.72; P = .016). When asymptomatic, the concussion group committed fewer speed exceedances (median difference, 2; P = .002) and had lower SDLP while navigating through a traffic light compared with controls ( d = 0.60; P = .045). No differences were evident at return to sport. Groups did not differ in total collisions at any time point. Conclusion: The concussion group showed more impaired driving patterns within 72 hours of injury, drove more conservatively once asymptomatic, and had similar driving performance at the time they returned fully to sport. Clinicians should consider these findings when discussing driving with patients acutely after concussion. Further research is needed to determine whether on-road collision risk is elevated after concussion.
