Figure 7.

Effect of user practice on muscle force and output variability. (A) Average raw EMG power of used and non-used electrodes for real-time decoding in early vs. late blocks. (B) One-to-one comparison of raw EMG power between early and late blocks. (C) Average finger position variability during the evaluation phase of the real-time posture matching task in early vs. late blocks for EMG and glove control. (D) One-to-one comparison of finger position variability between early and late blocks. SD, standard deviation.
