Abstract:Ground reaction force (GRF) measurements provide insight into biomechanical load. This helps manage load and reduce injury risk. Currently measurement of the ground reaction force is restricted to laboratory settings. To estimate ground reaction force in other environments IMU’s can be used to track the runners movement from which the ground reaction force can be estimated. The goal of this study is to estimate ground reaction force using a single IMU located on the sternum, with the end goal of improved injury prevention. This study explores the application of a mass, spring, damper model where the ground reaction force is estimated using a dual-Kalman filter. This method has the benefits of dynamic estimation of the model parameters as well as the unknown input. For this study 13 participants ran at a speed of 10km/h at their preferred stride frequency. GRF estimates were validated against an instrumented treadmill. Accuracy was measured using RMSE, peak errors, and Pearson’s r with results: an RMSE of 0.214BW , absolute mean peak error of 0.1000BW , relative mean peak error of 4.500% and a Pearson’s coefficient of 0.96. Though outperformed by current methods, it shows promise for future single-sensor GRF estimation.
