To assess the players' risk of a subsequent injury after sustaining concussive injuries and their return-to-competition in German professional men's football. A prospective injury database in the 1st Bundesliga was created encompassing 7 seasons (2014/15-2020/21). Cox proportional hazard model analyzed whether a concussive injury increased the risk of a subsequent injury in the first year after the index injury. 6,651 injuries were reported (n=182 concussive injuries). The incidence rate was 0.15 (95% CI 0...

BACKGROUND: An association has been identified between concussion and lower extremity musculoskeletal injury (LEMSKI) after return to sports participation. However, the collegiate student-athlete studies have relied on relatively small single-institution studies, which limits generalizability. PURPOSE: To assess odds of, and time to, LEMSKI after concussion in US collegiate athletes, using the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP)...

CONTEXT: Post-concussion reaction time deficits are common, but existing assessments lack sport-related applicability. We developed the Standardized Assessment of Reaction Time (StART) to emulate simultaneous cognitive and motor function demands in sport, but its reliability is unestablished. OBJECTIVE: To determine the intra-rater, inter-rater, and test-retest reliability of StART, and examine the dual-task effect, time effect, and relationships between StART and computerized and laboratory-based functional reaction time assessments...

BACKGROUND: The symptom presentation after sport-related concussion is highly subjective, while the clinical test of reaction time (RT) has been presented as an objective tool to the effects of sport-related concussion. A multimodal assessment approach supports concussion management; therefore, it is appropriate to explore the relationship between modals. The aim of the present study is to investigate the relationship of clinical RT and post-concussion symptom (PCS) score, number of experienced concussions, and time since concussion...

OBJECTIVE: Reaction time is a common deficit following concussion, making its evaluation critical during return-to-play protocol. Without proper evaluation, an athlete may return-to-play prematurely, putting them at risk of further injury. Although often assessed, we propose that current clinical testing may not be challenging enough to detect lingering deficits. Thus, the aim of this study was to examine reaction time in concussed individuals three times over a 30-day period through the use of a novel reaction time device consisting of simple, complex, and go/no-go reaction time tasks...

CONTEXT: Reaction time is commonly assessed postconcussion through a computerized neurocognitive battery. Although this measure is sensitive to postconcussion deficits, it is not clear if computerized reaction time reflects the dynamic reaction time necessary to compete effectively and safely during sporting activities. Functional reaction time assessments may be useful postconcussion, but reliability must be determined before clinical implementation. OBJECTIVE: To determine the test-retest reliability of a functional reaction time assessment battery and to determine if reaction time improved between sessions...

IMPORTANCE: Symptom-based methods of concussion diagnosis in contact sports result in underdiagnosis and repeated head injury exposure, increasing the risk of long-term disability. Measures of neuro-ophthalmologic (NO) function have the potential to serve as objective aids, but their diagnostic utility is unknown. OBJECTIVE: To identify NO measures that accurately differentiate athletes with and without concussion. DESIGN, SETTING, AND PARTICIPANTS: This cohort study was conducted among athletes with and without concussion who were aged 17 to 22 years between 2016 and 2017...

CONTEXT: Current international consensus endorses a multimodal approach to concussion assessment. However, the psychometric evaluation of clinical measures used to identify postconcussion performance deficits once an athlete is asymptomatic remains limited, particularly in the pediatric population. OBJECTIVE: To describe and compare the sensitivity and specificity of a multimodal assessment battery (balance, cognition, and upper and lower body strength) versus individual clinical measures at discriminating between concussed youth athletes and noninjured controls when asymptomatic...

CONTEXT: Pre-season testing is often used to establish baseline scores for post-concussion interpretation. However, pre-season testing can be time-intensive and cost-prohibitive, in which case normative data may be used for post-injury interpretation. OBJECTIVE: To compare change from baseline and normative-based cutoff scores in interpreting clinical reaction time (RTclin) following concussion. DESIGN: Prospective case-control study. SETTING: Multi-site study with testing completed in university athletic training rooms...

Reaction time testing is widely used in online computerized concussion assessments, and most concussion studies utilizing the metric have demonstrated varying degrees of difference between concussed and non-concussed individuals. The problem with most of these online concussion assessments is that they predominantly rely on consumer grade technology. Typical administration of these reaction time tests involves presenting a visual stimulus on a computer monitor and prompting the test subject to respond as quickly as possible via keypad or computer mouse...

Concussion is associated with significant functional disturbances in the first week post-injury. Computerized neurocognitive testing tools have become widely adopted in concussion management, to identify specific domains of impairment and obtain more objective measures of recovery. Reaction time (RT) slowing is a common sequela of concussion, however, the functional brain networks that underlie RT performance remain under-studied in both healthy and concussed athletic cohorts. This study used blood-oxygenation-level-dependent function magnetic resonance imaging (BOLD fMRI) to evaluate resting brain function of 45 university-level athletes with concussion in the first week post-injury, along with a control cohort of 102 athletes without recent concussion...

The use of virtual reality (VR) technology continues to grow in the areas of clinical assessment and rehabilitation. Both researchers and health-care providers are exploring ways to incorporate VR in clinical practice as an emerging technology. VR postural control and neuropsychological testing represent a promising next step in sport-related concussion (SRC) management. This article reviews the current literature on VR applications for SRC assessment. Relevance for Patients: VR-based postural control assessments suggest that visual motion is destabilizing following SRC, perhaps indicating persistent perceptual-motion disintegration when clinical postural control tests suggest complete recovery...

A sport-related concussion (SRC) results in short- and long-term deficits in oculomotor control; however, it is unclear whether this change reflects executive dysfunction and/or a performance decrement due to an increase in task-based symptom burden. Here, individuals with a SRC - and age- and sex-matched controls - completed an antisaccade task (i.e., saccade mirror-symmetrical to a target) during the early (initial assessment: ≤12 days) and later (follow-up assessment: < 30 days) stages of recovery. Antisaccades were used because they require top-down executive control and exhibit performance decrements following a SRC...

CONTEXT: In the absence of baseline testing, normative data may be used to interpret postconcussion scores on the clinical reaction-time test (RTclin ). However, to provide normative data, we must understand the performance factors associated with baseline testing. OBJECTIVE: To explore performance factors associated with baseline RTclin from among candidate variables representing demographics, medical and concussion history, self-reported symptoms, sleep, and sport-related features...
