 stroke subjects who had various levels of functional impairment (Motor status scale 00.00--00.00, Fugl-Meyer score 00--00), as shown in Figure [0](#F0){ref-type="fig"}. The ANOVA showed a significant difference among the decoding performances for the shoulder, elbow and wrist joints \[One-way ANOVA, *F*~(0,\ 00)~ = 0.00, *P* = 0.0000, partial eta squared ${\eta_{p}}^{0} =$ 0.00\]. The decoding accuracy for the wrist was lower than that achieved for the shoulder and elbow (Bonferroni test, *P* \< 0.00).  ![Cross-validated position decoding performance characterized by the VAF over all
