Head Kinematics and Upper Neck Loading During Simulated Low-Speed Rear-End Collisions: A Comparison With Vigorous Activities of Daily Living 2006-01-0247
Several studies have sought to investigate the biomechanics associated with “whiplash syndrome” by evaluating head kinematics in simulated low-speed rear-end collisions. However, the present study is the first to comprehensively measure head accelerations in six degrees of freedom for the purpose of estimating upper neck loads. In the first phase of the study, nine volunteers were instrumented with a sensor package to measure three-dimensional linear accelerations and angular velocities of the head during rear-end impacts while riding an amusement park bumper car. In the second phase, thirty volunteers were instrumented with the same sensors during selected vigorous activities, including hopping and skipping rope. The linear and rotational head accelerations as well as the calculated upper neck forces and moments for the two groups are presented and compared.
