Clinically feasible dual-task detects residual post-concussion deficits after return-to-play.

Dual-task (DT) has been shown to detect post-concussion deficits even after traditional measures returned to normal. However, previous studies were conducted in laboratory settings that were not feasible in the clinical setting. Prospective Cohort Study.

Driving after Concussion: Symptom Clusters and Neurocognition Uniquely Relate to Post-Concussion Driving Performance.

Purpose: To identify clinical concussion assessment outcomes that uniquely capture simulated driving performance among acutely concussed individuals, relative to controls.

Methods: Cross-sectional design. Twenty-eight college students within 72-hours of concussion and 46 non-concussed controls participated in the study.

Single-Task and Dual-Task Gait Performance After Sport-Related Concussion: A Machine Learning Statistical Approach.

Background: This study evaluated 2 different dual-task (DT) conditions during tandem gait (TG) to predict sport-related concussion (SRC) diagnosis.

Hypothesis: The best (fastest) single-task (ST) gait will differ between groups (controls vs SRC; baseline vs SRC), with auditory pure switching task (APST) response rate being the most important behavioral variable to aid prediction of SRC.

Study Design: Cohort design.

Helmetless Tackling Training Intervention and Preseason Self-efficacy Effects on Head Impacts in Hawai'i High School Football.

Objective: To determine how football head impacts are influenced by self-efficacy (SE), helmetless tackling intervention participation (IP), and years of experience (YE) playing football.

Design: Cross-sectional.

Setting: Three high schools.

TEST-RETEST RELIABILITY AND RELIABLE CHANGE INDEX OF MOBILE APPLICATION NEUROCOGNITIVE TEST AMONG MIDDLE AND HIGH SCHOOL ATHLETES.

Context: A mobile application neurocognitive assessment has been used in place of equipment intensive computerized neurocognitive assessment protocol. A previous study reported high to very high test-retest reliability of neurocognitive assessment using the mobile application in healthy adults, but no studies have examined test-retest reliability, reliable change indices (RCIs), and sex effect in middle school and high school populations when conducted 1 year apart.

Objective: The purpose of this study was to examine the test-retest reliability and RCIs of baseline data collected at 2-time points approximately 1 year apart using a mobile application neurocognitive rest in middle school and high school athletes.
