Summary of EMG prediction stability rates (R2 ± S EM) using Wiener cascade filter, SCKF (time delay: 20 ms and 40 ms), and FCKF (time delay: 40 ms time delay and kernel width: 40 ms). Predictions accounted for about 55% of the actual EMGs using SCKF, (eq. (15)), and about 45% using FCKF, (eq. (12)). Prediction rates obtained by SCKF were higher than that of the Wiener cascade filter by about 12% on average.
