Level of Agreement Between Child and Parent Reporting on the Child Sport Concussion Assessment Tool (SCAT5).

CONTEXT: The Child Sport Concussion Assessment Tool, fifth edition (SCAT5), remains the consensus instrument for concussion evaluation in youth athletes. Both child and parent are recommended to complete the athlete background and symptom reporting. OBJECTIVE: To determine the level of agreement between child and parent medical history and symptom reporting and quantify their performance on the Child SCAT5 in male football athletes. DESIGN: Cross-sectional study. SETTING: National Collegiate Athletic Association Division I college football facility. PATIENTS OR OTHER PARTICIPANTS: A total of 157 youth male football athletes (age = 10.7 ± 1.3 years) participating in a university-sanctioned youth football camp and their parent or legal guardian. MAIN OUTCOME MEASURE(S): Youth athletes and their parent completed the athlete background (demographics, diagnosed medical history) and symptom evaluation (symptom items, total number of symptoms, and symptom severity score) of the Child SCAT5 and were instructed not to discuss reporting with each other during testing. Cronbach α tests were conducted to determine the internal consistency, and descriptive statistics determined the level of agreement between medical history, symptom reporting, and baseline performance. RESULTS: The internal consistency of the symptom items was high for both child (Cronbach α = 0.91) and parent (α = 0.92). Agreement on medical history ranged from 67% (learning disability or dyslexia) to 85% (attention-deficit/hyperactivity disorder), with 82% agreement on sustaining a previous concussion. Fourteen youth athletes reported having been hospitalized for a head injury, with zero matched parent confirmations. Individual symptom agreement ranged from 70.7% (gets distracted easily) to 94.9% (going to faint). Agreement was 35% on total number of symptoms and severity. Abnormal scoring ranged from 2% (going to faint) to 25% (headache) for child and 2% (double vision) to 28% (gets distracted easily) for parent reporting. CONCLUSIONS: Fair agreement was shown between children and their parent on medical history and self-reported symptoms on the Child SCAT5 at baseline. When available, child and parent reporting should be used for concussion assessment and clinical decision-making.

Effects of attention deficit hyperactivity disorder and learning disability on vestibular and ocular baseline concussion assessment in pediatric athletes.

Vestibular and ocular motor assessment has gained popularity as a tool for sport-related concussion among healthcare professionals. With awareness of premorbid risk factors, such as attentional problems, it is imperative to understand their effects at baseline. The purpose of this study was to examine the effects of attention deficit/hyperactivity disorder (ADHD) and diagnosed learning disability (LD) on vestibular and oculomotor baseline concussion assessment in pediatrics. Pediatric athletes between the ages of 8 and 14 years with ADHD/LD (n = 30) and match controls without ADHD/LD (n = 30) completed baseline concussion testing, consisting of symptom provocation on the Vestibular/Ocular Motor Screening (VOMS) and oculomotor performance on near point of convergence (NPC) and King-Devick (K-D) tools. Those diagnosed with ADHD/LD performed worse on baseline saccades (p range = .02-.10), convergence (p = .04), vestibular ocular reflex (VOR) (p = .03) and visual motion sensitivity (VMS) (p = .04) of the VOMS. Base rate analyses revealed that 26% of athletes in the ADHD/LD group had ≥1 and 13.3% had ≥2 VOMS domains over clinical cutoff levels, compared to 3.3% (≥1 domain) and 0 (≥2 domains) of controls. Individuals with ADHD/LD also performed worse on K-D assessment (p = .005). However, no differences were reported on NPC distance (p = .19). These findings suggest worse baseline concussion assessment scores on vestibular/ocular motor assessment domains in pediatric athletes diagnosed with ADHD/LD. Additional research is needed on assessment outcomes to determine if special consideration to those diagnosed with ADHD/LD is warranted.

Exploring Baseline Concussion-Assessment Performance in Adapted Wheelchair Sport Athletes.

CONTEXT: With growing awareness of and advocacy for including individuals with disabilities in sport, implementation of concussion-assessment and -management strategies is warranted. Limited research is available on concussion assessment in adapted wheelchair sport athletes. OBJECTIVE: To examine baseline symptom reporting, computerized neurocognitive testing, and a modified balance scoring system in adapted athletes. A secondary objective was to provide preliminary normative data for this population. DESIGN: Cross-sectional study. SETTING: University athletic training room and computer laboratory. PATIENTS OR OTHER PARTICIPANTS: Twenty-one athletes (age = 22.1 ± 3.0 years) from 1 institution's collegiate adapted athletics program. MAIN OUTCOME MEASURE(S): Athletes completed baseline Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) and the Wheelchair Error Scoring System (WESS) before the start of their respective seasons. Symptom reporting variables consisted of total symptoms, symptom severity scores, and baseline symptom factors (eg, vestibular-somatic, sleep arousal, cognitive-sensory, and affective). We analyzed ImPACT composite scores of verbal memory, visual memory, visual motor processing speed, and reaction time and impulse control to determine neurocognitive function. Balance performance was quantified using the WESS condition and overall errors. RESULTS: Compared with normative reference values, 17 (81%) of adapted athletes reported greater symptoms and 20 (95%) performed at or below average on at least 1 neurocognitive composite score. Mean errors on the WESS were 3.14 ± 2.9, with 81% committing ≥1 error. Sex differences were not present for symptoms, neurocognitive testing, or balance measures. CONCLUSIONS: Our findings provide context for baseline performance in adapted athletes and help to further develop the WESS as an assessment of balance in these athletes.

Sex differences and normative data for the m-CTSIB and sensory integration on baseline concussion assessment in collegiate athletes.

Primary objective: To investigate sex differences on baseline m-CTSIB and sensory integration function between male and female collegiate athletes and develop preliminary normative data for this population.Methods and procedures: Baseline data were retrospectively analyzed for 591 National Collegiate Athletic Association (NCAA) athletes between 2015 and 2018 on the modified Clinical Test for Sensory Interaction and Balance (m-CTSIB). A series of Mann-Whitney U tests were conducted to determine sex differences on m-CTSIB and individual sensory integration performance.Main outcomes and results: Female athletes performed significantly better than male athletes on baseline m-CTSIB composite scores (p < .001). Females also performed better on the eyes open-firm surface (p < .001), eyes closed-firm surface (p = .001), eyes open-foam surface (p < .001), and eyes closed-foam surface (p = .001) tasks as compared to male athletes.Conclusions: Male and female athletes exhibit differences on baseline m-CTSIB and sensory integration test performance. The m-CTSIB normative data are presented for the total sample and by sex. These normative data provide a frame of reference for interpreting m-CTSIB performance in collegiate athletes as part of concussion assessment.

Sex Differences on Vestibular and Ocular Motor Assessment in Youth Athletes.

CONTEXT: The Vestibular/Ocular Motor Screening (VOMS) is a newly developed measure that evaluates vestibular and ocular motor symptom provocation after sport-related concussion. The effects of sex on baseline VOMS scores in youth athletes have not been established. OBJECTIVE: To examine sex differences on baseline VOMS assessment among youth athletes. RESULTS: No sex differences were demonstrated between male and female youth athletes on individual VOMS items (P range = .07-.98). Female sex was not associated with increased odds for VOMS scores over clinical-cutoff levels (range: odds ratio = 0.64; 95% confidence interval = 0.35, 1.15; P = .13; odds ratio = 0.91; 95% confidence interval = 0.48, 1.71; P = .77). CONCLUSIONS: No sex differences were present on baseline VOMS scores in youth athletes, nor was sex a risk factor for an abnormal VOMS score. These findings highlight the need for continual baseline and postconcussion assessments using multifaceted assessment strategies.

Premorbid migraine history as a risk factor for vestibular and oculomotor baseline concussion assessment in pediatric athletes.

OBJECTIVEMigraine history has recently been identified as a risk factor for concussion and recovery. The authors performed a cross-sectional study examining baseline outcome measures on newly developed and implemented concussion assessment tools in pediatrics. The purpose of this study was to examine the effects of premorbid, diagnosed migraine headaches as a risk factor on vestibular and oculomotor baseline assessment in pediatric athletes.METHODSPediatric athletes between the ages of 8 and 14 years with a diagnosed history of migraine headache (n = 28) and matched controls without a history of diagnosed migraine headache (n = 28) were administered a baseline concussion assessment battery, consisting of the Vestibular/Ocular Motor Screening (VOMS), near point of convergence (NPC), and the King-Devick (K-D) tests. Between-groups comparisons were performed for vestibular symptoms and provocation scores on the VOMS (smooth pursuit, saccades, convergence, vestibular/ocular reflex, visual motion sensitivity), NPC (average distance), and K-D (time).RESULTSIndividuals diagnosed with migraine headaches reported greater VOMS smooth pursuit scores (p = 0.02), convergence scores (p = 0.04), vestibular ocular reflex scores (p value range 0.002-0.04), and visual motion sensitivity scores (p = 0.009). Differences were also observed on K-D oculomotor performance with worse times in those diagnosed with migraine headache (p = 0.02). No differences were reported on NPC distance (p = 0.06) or headache symptom reporting (p = 0.07) prior to the VOMS assessment.CONCLUSIONSPediatric athletes diagnosed with migraine headaches reported higher baseline symptom provocation scores on the VOMS. Athletes with migraine headaches also performed worse on the K-D test, further illustrating the influence of premorbid migraine headaches as a risk factor for elevated concussion assessment outcomes at baseline. Special consideration may be warranted for post-concussion assessment in athletes with migraine headaches.
