Helmet-testing headforms replicate the human head impact response, allowing assessment of helmet protection and injury risk. However, industry uses three different with varying inertial friction properties making study comparisons difficult because these have that may affect their response. This aimed to quantify influence headform coefficient (COF) on oblique The static COF each condition (EN960, Hybrid III, NOCSAE, III a skull cap, NOCSAE cap) was measured against lining material used in...
Abstract Purpose This study evaluates the accuracy of a model-based image matching (MBIM) approach with model calibration for tracking head impact speeds in uncalibrated spaces from single-camera views. Methods Two validation datasets were used. The first included 36 videos guided NOCSAE headform drops at varying camera positions (heights, distances, angles) where speed gate measured vertical speed. second dataset had eight participants performing ladder falls marked helmets, captured using...
Dummy headforms used for impact testing have changed little over the years, and frictional characteristics are thought not to represent human head accurately. The interface between helmet is an essential factor affecting response. However, few studies evaluated coefficient of friction (COF) surface. This study's objectives were quantify head's static dynamic COF evaluate effect biological sex hair properties. Seventy-four participants slid their heads along a piece foam backed by fixed load...
Patients with ankle arthritis (AA) have side-to-side limb differences at the and in spatiotemporal measures; however, degree of symmetry between limbs has not been compared to a healthy population. The purpose this study was determine during walking for discrete time-series measures when comparing patients unilateral AA participants. Thirty-seven 37 participants were age, gender, body mass index matched. Three-dimensional gait mechanics ground reaction force (GRF) captured four seven trails....
<div>Head injuries account for 15% of snowsport-related injuries, and the majority head impacts occur against ice or snow, low-friction surfaces. Therefore, this study aimed to evaluate how surface friction affects snowsport helmets’ oblique impact kinematics. Ten helmet models were impacted using an drop tower with a 45-degree anvil NOCSAE headform, at three locations, two conditions, speed 5.0 m/s. Our findings indicate that peak linear acceleration, rotational velocity during...
Background: Patients with ankle arthritis have decreased symmetry at the ankle, and in spatiotemporal variables; however, degree of asymmetry has not been compared to a healthy population. The purpose this study was determine differences limb during walking for discrete continuous outcome measures when comparing patients end-stage unilateral participants.Methods: Thirty-seven 37 participants were age, gender, BMI matched. Three-dimensional gait mechanics ground reaction forces captured four...
