Experimental paradigm. (A) During the EEG experiment, the participant wore a 64-channel EEG cap and sat in front of a computer screen on which a visual cue of a hand movement was shown. The participant attempted the hand movement with or without tTENS. (B) The experiment consisted of four conditions: Pre-Stim, Stim-Only, Stim-Move, and Post-Stim. (C)–(E) Each participant with upper limb amputations selected different hand movements and stimulation regions. (C) Participant A01 associated median sensation with tripod, ulnar sensation with point, and wrist sensation with wrist flexion. (D) A02 associated median sensation with hand open, and wrist sensation with hand close. (E) A03 associated sensation on the back of the hand with hand open.
