Instrumented Mouthguard Laboratory Evaluation using Two Anthropometric Test Device Headforms
Abstract
This study is in support of the Human Head Impact Dose Concussion Risk Functions and Sensor-Based Military-Specific Environmental Monitoring System project (BA150149, W81XWH-17-1-0019). Test methods and results comparing the measured kinematics using a boil-and-bite instrumented mouthguard with reference kinematics from two ATD headforms under multiple exposure types and severities are provided. Mouthguard performance was comparable to prior literature; however, there was an increase in variability due to fitting. The Mandible Load Sensing Headform resulted in poor comparisons between the mouthguard and the reference due to several issues with jaw movement and interactions with the mouthguard. A modified NOCSAE headform resulted in good comparisons between the mouthguard and reference data. Increased variability in mouthguard response compared to the reference was primarily attributed to the use of boil-and-bite versus fully custom-molded mouthguards commonly used in the literature. While increased, when compared to custom-molded mouthguards, the variability was still minimal.
