Fig. 4.

Depicted here are the same three performance measures as seen in Fig. 3 with 8 h elapsed between sessions. Subjects trained and evaluated a movement classifier during the final morning of the study. Subjects wore the electrode cuff for 8 h and were tested again without retraining the movement classifier. Subject 3 required a small cuff realignment due to obvious displacement of the cuff (approx. 1.5-cm shift distally) during the 8 h between sessions. Asterisks indicate significance (*: p < 0.05; **: p < 0.01; * * *: p < 0.001).
