“…The present findings combined with previous discoveries [8] may partially explain why youth who returned to game-play after a concussion are at a higher risk of incurring another concussion or injury within the first year post-injury [11,12]. In previous studies, it was shown that lingering eye-hand decoupling deficits remained present for much longer than previously expected in both asymptomatic youth [8,9] and asymptomatic elite athletes [14] who had all returned to play. In the present study, we expand on these findings with details about the time course of EHD deficits in youth with concussion history to include task demand.…”

“…In line with these findings, previous work has shown prolonged eye-hand coordination deficits in youth with concussion history for up to 1.5 years post-concussion when participant's performed a challenging cognitive-motor task that required a decoupling of eye and hand movement direction [8,9]. Importantly, all of the young athletes involved in these studies had already returned to game play after their concussion, in accordance with the current return to play protocols at the time the concussion-incident occurred [10].…”

“…We re-analyzed data from 114 youth participants who were already part of previous studies [8,9]. The present data set included 59 participants with a history of sport-related concussion (13.00 ± 1.82 yr; 29 females) and 55 control participants with no history of concussion (12.04 ± 1.89 yr; 23 females).…”

“…In the current study, we focused on variables that reached statistical significance between groups (Concussion history, No-history) in previous studies, i. e. movement time (MT) and path length (PL) [8]. In addition, we added response time (RespT) and reaction time (RT), since both variables provide further insight into MT and PL and their potential relationships.…”

The present study expands previous work on eye-hand decoupling deficits in youth with concussion history. It examines whether deficits can be linked to difficulties adapting to new task constraints or meeting ongoing task demands. Data from 59 youth with concussion history (M=11 months post-concussion) and 55 no history controls were analyzed. All 114 participants (M=12.5 yrs.) performed two touchscreen-based eye-hand coordination tasks: A standard task with vision and motor action in alignment, and an eye-hand decoupling task with both spatially decoupled, with twenty trials per task condition. First (trial 1–4), middle (trial 9–12), and last (trial 17–20) trial blocks were analyzed in each condition across groups, as well as first and last blocks only. The latter analysis showed in the first block longer response times in the concussion history group in the eye-hand decoupling condition due to a general slowdown of the reaction times across blocks and a trend for higher movement times. Our findings suggest that youth with concussion history have difficulty to adapt to new task constraints associated with complex skill performance during a short series of trials. These results are relevant for athletic trainers, therapists and coaches who work with youth with concussion history.

Adolescents who are clinically recovered from concussion continue to show subtle motor impairment on neurophysiological and behavioral measures. However, there is limited information on brain–behavior relationships of persistent motor impairment following clinical recovery from concussion. We examined the relationship between subtle motor performance and functional connectivity of the brain in adolescents with a history of concussion, status post‐symptom resolution, and subjective return to baseline. Participants included 27 adolescents who were clinically recovered from concussion and 29 never‐concussed, typically developing controls (10–17 years); all participants were examined using the Physical and Neurologic Examination of Subtle Signs (PANESS). Functional connectivity between the default mode network (DMN) or dorsal attention network (DAN) and regions of interest within the motor network was assessed using resting‐state functional magnetic resonance imaging (rsfMRI). Compared to controls, adolescents clinically recovered from concussion showed greater subtle motor deficits as evaluated by the PANESS and increased connectivity between the DMN and left lateral premotor cortex. DMN to left lateral premotor cortex connectivity was significantly correlated with the total PANESS score, with more atypical connectivity associated with more motor abnormalities. This suggests that altered functional connectivity of the brain may underlie subtle motor deficits in adolescents who have clinically recovered from concussion. More investigation is required to understand the persistence and longer‐term clinical relevance of altered functional connectivity and associated subtle motor deficits to inform whether functional connectivity may serve as an important biomarker related to longer‐term outcomes after clinical recovery from concussion.

Background: Studies have demonstrated an increased risk of musculoskeletal (MSK) injury after concussion in collegiate and professional athletes, but there has been relatively little study of this relationship in younger athletes.Objective: To determine the odds of experiencing a subsequent MSK injury after concussion in high school athletes. It was hypothesized that concussion would increase the risk of MSK injury within 365 days of the concussion event.Design: Retrospective observational study. Setting: Twelve high school sports programs. Participants: Athletes (n = 14,461) from athletic training room records queried between 2010 and 2017. Independent Variables: History of concussion and history of concussion and MSK injury in the year preceding MSK injury. Main Outcome Measures: General estimating equation analyses were conducted to examine the odds of MSK injury related to (1) concussion within the preceding 365 days of injury; and (2) concussion and MSK injury within the preceding 365 days of concussion. Results: Respectively, 8% and 8.3% of athletes were identified with a concussion and MSK injury. After controlling for gender and sport, athletes with a concussion and prior MSK injury (odds ratio = 2.19, 95% confidence interval: 1.02-4.67) and athletes with a concussion alone (odds ratio = 1.67, 95% confidence interval: 1.15-2.44) both had higher odds of experiencing a subsequent MSK injury compared to athletes without prior concussion. Conclusions: High school athletes who sustain a concussion have elevated odds of MSK injury at rates comparable to those for collegiate athletes. These findings support the use of neuromuscular-based rehabilitation and injury prevention protocols in the post-concussion period. These findings may also suggest exploring methods to modify concussion return-to-play criteria with the goal to reduce the risk of future MSK injury.
