“…The LODC is an ATD representing a 10-year-old developed as part of the continued research activities of the National Highway Traffic Safety Administration (NHTSA) to improve the performance of, and address biofidelity concerns surrounding the Hybrid III 10-year-old ATD. 27,28 The LODC ATD has several key design differences compared to the Hybrid III 10-year-old ATD, including a modified headform with inertial properties matching pediatric specimens and a neckform that permits elongation and lateral rotation at the atlanto-occipital joint. The LODC ATD headform was instrumented with a triaxial linear accelerometer (model 7264, Endevco, Depew, NY, USA) and a triaxial angular rate sensor (model ARS18K, Endevco, Depew, NY, USA).…”

Recent advances in technology have enabled the development of instrumented equipment, which estimate the head impact kinematics of athletes in vivo. One such headband-mounted impact sensor is the SIM-G (Triax Technologies, Norwalk, CT, USA), which has been previously used to investigate the biomechanics of soccer heading by human subjects. Previous studies have evaluated the accuracy of the SIM-G for pure rotation and pendulum, impulse hammer and drop rig impacts. The current study used a soccer ball heading model to evaluate the accuracy of the SIM-G. A soccer ball was projected at the head of an anthropomorphic test device (ATD) representing a 10-year-old to replicate the heading maneuver at various impact sites, angles and speeds previously identified in youth soccer. Linear regression revealed that the SIM-G sensor overestimated the peak angular velocity and linear acceleration recorded by the ATD headform by approximately 44% and 105%, respectively. Tests in which the ball directly contacted the SIM-G sensor resulted in the largest peak linear accelerations. Glancing impacts were significantly associated with a decrease in percentage error of the SIM-G sensor peak angular velocity data relative to the ATD reference data. While it may not demonstrate accuracy in estimating the magnitudes of head impacts, the SIM-G remains a useful tool to provide estimates of head impact exposure for soccer players.

“…Several studies have described improvements to the biofidelity of existing ATDs to improve the accuracy of the event dynamics and loads measured. 17–19 Changes to anthropometry (shape), joint range of motion, and material properties (stiffness) to more closely represent humans have been shown to improve biofidelity.…”

Fall dynamics play an important role in the biomechanical assessment of falls. Fall height was found to influence both fall dynamics and femur loading, while impact surface affected only compression and bending in feet-first falls; fall dynamics did not differ across carpet and linoleum. Improved pediatric thresholds are necessary to predict likelihood of fracture, but morphologically accurate representation of the lower extremity, along with accurate characterization of loading in falls are a crucial first step.
