Fig. 9From: Role of Muscle Synergies in Real-Time Classification of Upper Limb Motions using Extreme Learning MachinesThe average standard deviation of muscle activity. The mean of the standard deviation values of the muscle activity across all muscles during the entire motion (standard deviation values are as shown in Fig. 8) is indicated for each subject and each motion-class, in the case of EMG features and synergy feature Back to article page
