TABLE 1.
Mean ± standard deviation of the root mean squared deviation (RMSD) between inertial and marker tracking simulations. The results were summarized over all variables of the specific type (e.g., over all accelerations) and all trials of the respective motions straight running (SR), curved running (CR), and v-cut (VC).
