Prior eye movement recorded studies of the K—D test for early detection of hypoxia related cognitive impairment have also shown that errors correlated with hypoxic impairment. Future studies are recommended to investigate the additive effect of sideline K—D test and the new SCAT3 for detection of concussion.

Results of our study show that K-D test time scores have a high degree of test-retest reliability, with ICCs of 0. Posted by Jeffrey S. Standard and routine headgear and sparring-grade boxing gloves were worn.

Rapid screening tools that can be practically implemented into the sideline evaluation of athletes are vital to the detection of concussive injuries.

For this cross-sectional study, boxers and MMA fighters were recruited and enrolled prior to sparring sessions and matches conducted in the Boston, MA, area.

The range of the box corresponds to the interquartile range between the 25th and cooncussion 75th percentile. Corrections were made for near vision as needed. Concussed athletes performed slower on their sideline K—D test compared to baseline with an average slowing from baseline of 4. Impaired eye movement function, particularly for those reflecting subcortical pathways, correlated well with severity of postconcussive symptoms and with limitation of activities of daily living.

Concussion signs and symptoms may develop and evolve over time, particularly within the first hours following injury. Testing procedures Baseline K—D times for all athletes were established during pre-season physical exams with multiple individuals being testing simultaneously in a noisy training room environment. During the playing season, the K—D test and a modified version of the Sport Concussion Assessment Tool 2 SCAT2 were both utilized in the sideline assessment of athletes suspected of head trauma.
