Abstract :
A time-frequency analysis technique with Wigner-Ville distribution was developed for discriminating a set of upper limb motions using just one channel surface EMG signals. EMG data were obtained from the distal portion of the deltoid. The limb motions included elbow extension/flexion, wrist pronation/supination, and wrist abduction/adduction. The 2D cross-correlation was employed for classification of the upper limb functions
