Classification error for each classifier type, trained with either surface or intramuscular EMG. Parallel classifiers are trained with both 1-DOF and 2-DOF motion training data. Error is presented as an overall error, and broken into error for classification of no motion, 1-DOF intended motions and 2-DOF intended motions. For the parallel classifiers, the use of imEMG provided significant improvement in classification error when compared to sEMG. Results are an average of four subjects. * p<0.05, ** p<0.01, *** p<0.001. Error bars show +/− 1 SEM. (IM = intramuscular, NM = no motion)
