Technological framework and experimental design. (a) Hardware setup. Technological framework for EEG and EMG signal acquisition and the delivery of tSCS using BCI2000 [17]. (b) Phase I experimental protocol. Phase I consisted of 3 conditions, 6 blocks per condition, and 10 trials (repetitions) per block. Cued movement blocks were used to train the decoder with 5-fold cross-validation, with the sixth block reserved for testing
