Identification of head impact locations, speeds, and force based on head kinematics
Xianghao Zhan, Yuzhe Liu, Nicholas J. Cecchi +5
Objective: Head impact information including impact directions, speeds and force are important to study traumatic brain injury, design and evaluate protective gears. This study pre…
Denoising instrumented mouthguard measurements of head impact kinematics with a convolutional neural network
Xianghao Zhan, Yuzhe Liu, Nicholas J. Cecchi +6
Wearable sensors for measuring head kinematics can be noisy due to imperfect interfaces with the body. Mouthguards are used to measure head kinematics during impacts in traumatic b…
Padded Helmet Shell Covers in American Football: A Comprehensive Laboratory Evaluation with Preliminary On-Field Findings
Nicholas J. Cecchi, Ashlyn A. Callan, Landon P. Watson +8
Protective headgear effects measured in the laboratory may not always translate to the field. In this study, we evaluated the impact attenuation capabilities of a commercially avai…
Physics-informed machine learning improves detection of head impacts
Samuel J. Raymond, Nicholas J. Cecchi, Hossein Vahid Alizadeh +6
In this work we present a new physics-informed machine learning model that can be used to analyze kinematic data from an instrumented mouthguard and detect impacts to the head. Mon…
A comparison of sports-related head accelerations with and without direct head impacts
Samuel J. Raymond, Yuzhe Liu, Nicholas J. Cecchi +9
Concussion and repeated exposure to mild traumatic brain injury are risks for athletes in many sports. While direct head impacts are analyzed to improve the detection and awareness…
Time Window of Head Impact Kinematics Measurement for Calculation of Brain Strain and Strain Rate in American Football
Yuzhe Liu, August G. Domel, Nicholas J. Cecchi +8
Wearable devices have been shown to effectively measure the head movement during impacts in sports like American football. When a head impact occurs, the device is triggered to col…
