Effect of inter-electrode distance on the amount of information. In these cases, EMG signal was segmented using a window length of 300 ms. RMS was used. Information values were calculated by considering abduction (Abd), adduction (Add) and both movements (Abd-Add). The arm position was discretized using 5°/bins, while the response discretization was realized according to number of data N (). (A) Information values for IED of 4 cm. (B) Information values for IED of 6 cm.
