Simultaneous acquisition of sEMG and EEG for four hand motions
This dataset contains the simutaneously acquired sEMG and EEG signals when 8 subjects performing hand motions.
Five males and three females are recruited to collect their EEG and sEMG signals. They are all healthy postgraduate students with an average age of 23.8. Four motion classes are involved in the protocol, including wrist flexion (WF), wrist extension (WE), fist grip (FG), five fingers open (FFO). During the experiments, each subject set at a comfortable chair in a quiet room, and a computer screen was placed about 40 cm from the subject at a stable table. For each subject, the experiment consisted of 40 repeated sessions, and each session contained four trials, in which every trial presented one movement. At the beginning of the experiment, the subject was instructed about the protocol and asked not to move the body during the recording. Before each trial, a sign of “ready to start” would appear on the screen and lasted for 1 second, and then a short text in “wrist flexion”, “wrist extension”, “fist grip”, “fingers open” would be displayed on the screen with a random order. Each prompt lasted for 5 s, and the subject kept the motion within the duration of it. Between each two trials, there was a 5 second rest. After 10 consecutive sessions, the subjects could rest until they were not fatigue.
