Mean Normalized RMSE of predicted kinematics. Joint kinematics were predicted for 9 transfemoral amputee subjects using two distinct testing sets: the normal speed testing set and the fast speed testing set. For the normal speed testing set, the mean normalized RMSE for the knee position, knee velocity, ankle position, and ankle velocity were 9.0 ± 3.1 %, 7.3 ± 1.6 %, 8.3 ± 2.3 %, and 10.0 ± 2.5 % respectively. For the fast speed testing set, the mean normalized RMSE for the knee position, knee velocity, ankle position, and ankle velocity were 15.7 ± 5.4 %, 12.6 ± 3.1 %, 14.0 ± 3.9 %, and 13.1 ± 2.0 % respectively. The error was calculated for the unfiltered prediction.
