abstract="Recent research findings have strongly suggested that sport-related concussion (SRC)  increases risk for subsequent injury of any type, as well as a potential for  long-term adverse effects on neurological and psychological well-being. The primary  purpose of this study was to explore the reliability and discriminatory power of  clinical testing procedures for detecting persisting effects of SRC. We used a  cross-sectional study design to assess both self-reported symptoms commonly  associated with post-concussion syndrome, and the effects of mental or physical  activity on metrics derived from a smartphone app designed to test perceptual-motor  responses. Among 30 physically active college students, 15 participants reported a  SRC occurrence prior to testing (M time-since-injury = 4.0 years, SD = 3.1,  range = 5 months to 11 years). We found good test-retest reliability for key metrics  derived from the smartphone app (ICC ≥.70); and the internal consistency for the  Overall Wellness Index (OWI) for 10 categories of 82 post-concussion symptoms was  ideal (Cronbach's α ≥.80). Moderate intensity treadmill running demonstrated the  strongest differential effect on perceptual-motor responses between participants  with a history of SRC (HxSRC) and those with no such history (No SRC), which was  best represented by the speed-accuracy trade-off quantified by the inverse  efficiency index (IEI: group X trial interaction p = .055). Self-reported OWI  symptoms ≥4 and post-physical activity IEI ≥ 568 ms provided the strongest  discrimination between HxSRC and NoSRC participants (≥1 versus 0: OR = 9.75). Our  findings suggest that persisting effects from a remote SRC occurrence can be  detected by easily administered screening procedures that have the potential to  identify individual athletes who might derive benefit from interventions to restore  their optimal function and well-being.<p /> <p>Language: en</p>",
