Figure 1.
Left side: SEFs recorded from contralateral hemisphere after separate stimulation of median nerve and the three fingers of left and right hands in an emblematic subject affected by left CTS. All recording channels are superimposed on the time interval of 100 msec after the stimulus and 40 msec pre‐stimulus. On the hemisphere contralateral to the CTS hand, note in digit 1 and digit 3 the selective amplification of M30 with respect to M20 component (dashed arrows), and the amplification of both components for the Digit 5 (solid arrows). Right side: Representation of the hand parameter, calculated as Euclidean distance between Digit 1 (TR) and Digit 5 ECD (LR) of each hand.
