Healthy controls
TB
Before the beginning of the whole clinical trial, the immediate alpha, beta, delta, and theta bands of the eyes-closed resting state EEG of the healthy controls in a quiet, without any interference laboratory will be recorded and ask them to do the “reaching and retrieving” gross movement, recording the real-time sEMG parameters (RMS and MF) of BB, TB, ECR, B, ED, and FCU during the whole process of the motion. The computer software calculates iEMG and MPF values.
