General linear models did not reveal statistically significant differences between groups. Within group analyses using paired t-tests demonstrated improvement in age-adjusted fluid cognition [t<sub>(13)</sub> = 3.39, p = 0.005, Cohen's d = 0.61] and crystallized cognition [t<sub>(13)</sub> = 2.63, p = 0.02, Cohen's d = 0.70] within the aerobic training group but no significant improvement within the stretching group. Paired t-tests demonstrated significant improvement in both self-reported and parent-reported total quality of life measures in the aerobic training group [self-report t<sub>(13)</sub> = 3.51, p = 0.004, Cohen's d = 0.94; parent-report t<sub>(13)</sub> = 6.5, p < 0.0001, Cohen's d = 1.80] and the stretching group [self-report t<sub>(14)</sub> = 4.20, p = 0.0009, Cohen's d = 1.08; parent-report t<sub>(14)</sub> = 4.06, p = 0.0012, Cohen's d = 1.045].</p><p>Conclusion: Quality of life improved significantly in both the aerobic exercise and stretching groups; however, this study suggests that only sub-symptom exacerbation aerobic training was potentially beneficial for neurocognitive recovery, particularly the fluid cognition subset in the NIH Toolbox. Limited sample size and variation in outcomes measures limited ability to detect between group differences. Future research should focus on developing larger studies to determine optimal timing post-injury and intensity of active rehabilitation to facilitate neurocognitive recovery and improve quality of life after mTBI.</p><p>Clinical Trial Registration:www.ClinicalTrials.gov, identifier: NCT02035579.</p> 2019-09-18 13:37:23 mTBI (mild traumatic brain injury) aerobic training neurocognitive quality of life pediatrics
