Fig. 3. Spinal cord injured participant performance for 12 sessions of BMI training.
(A) Participants performance at each session is shown for PCA (blue) and Kalman (red) SCI participants. Each marker type denotes a different participant’s mean performance at that session. The lines represent the map averages (n = 3 participants, 48 trials per session). (B) Improvement in performance (first – last) is shown for each map. (C) PCA was applied on 4 performance measures for all participants calculated over 12 successive sessions. Least-square elliptic fits are drawn to emphasize map differences in PC space. The matrix reports the normalized score of each performance measure along each PC. Data are means ± SEM (bars). a.u., arbitrary units.
