Examples of surface EMG signals recorded using the two electrode arrays. (A) Surface EMG signals recorded with the flexible electrode array from the thenar muscle. (B) Surface EMG signals recorded with the linear electrode array from the BB muscle. Channel 1 represents the most proximal channel.

The electrode arrays used for FP recordings. (A) shows a flexible surface electrode array (TMS International BV, Enschede, The Netherlands) that contains 64 recording electrodes arranged in an 8 × 8 square matrix. The inter-electrode-distance (IED) between two consecutive recording electrodes in both (x and y) directions is 4 mm and each recording electrode has a circular recording surface of 1.2 mm in diameter. (B) shows our custom made 20-channel bar electrode array. The distance between two consecutive recording bars is 5 mm and each bar width is 1 mm in a linear arrangement.
