Choosing the Optimal Trigger Point for Analysis of Movements after Stroke Based on Magnetoencephalographic Recordings

Figure 3

Mean wrist extensions of a typical subject: (a) Time course of electromyography signals in extensor and flexor muscles and wrist angle (one exemplary epoch; red: EMG signal of the extensor carpi ulnaris muscle; black: EMG signal of the flexor carpi ulnaris muscle; blue: wrist angle). (b) Overlay of magnetoencephalographic signals (148 channels) averaged with respect to movement onset. Time 0 indicates the extension M-onset.
