Conclusion: Our findings suggest that sustaining an impact greater than 90 g does not result in acute observable balance and neurocognitive deficits within 24 hours of sustaining the impact. Although previous studies have suggested a theoretical injury threshold, none have been founded on empirical data collected on the playing field in real-time. Future studies should consider the cumulative effects of impacts of varying magnitudes.
Excerpt: Participants were tested using the Automated Neuropsychological Assessment Metrics (ANAM) battery to assess neurocognitive function&The sports medicine battery has been used at our institution for more than 5 years and has been designed to maximize the benefits of computerized testing while minimizing the time needed to complete preseason baseline and post-injury follow-up testing.
