Predicted finger position by the mKFT and mTWTM for sample reaches at (a) slow; (b) normal and (c) fast speeds at the simulated C4 injury level. In this example, R2 for the mKFT and mTWTM respectively were: (a) 0.89, 0.96; (b) 0.99, 0.97 and (c) 0.86, 0.98. The target VAFs were: (a) 0.92, 0.97; (b) 0.98, 0.99 and (c) 0.85, 0.9.
