Measurement of EEG and EMG signals. A participant in the experimental trial is sitting on a chair with the eyes open and performing flexion and extension of the shoulder joint with a weight of 3 Kg. The movement is conducted for a duration about 60–80 times, consecutively within 5 min with their own pace. He wears an EEG measurement cap, the electrodes fixed on the cap and an electrode for the measurement of EMG signal are connected to the EEG amplifier and EMG amplifier, respectively. The amplified data are transmitted to the computer after the analog/digital(A/D) conversion and recorded.
