From: Estimation of ground reaction forces and ankle moment with multiple, low-cost sensors
(Top) Mean normalized right ankle moments as calculated by Inverse Dynamics and estimated by the multi-task, multi-day model for each of the seven sensor combinations on the three tasks. The angle and tendon sensors are not sufficient to predict moment for all of the tasks by themselves. (Bottom) Normalized root mean squared error (NRMSE) for the seven sensor combinations on the three different tasks. The insole sensor alone outperforms the all of the other sensors individually. Combining the angle and tendon sensor with the insole has a small benefit for the NRMSE
