Abbreviations: AIS, Frankel impairment degree; B2R, BCI and robot use; FN, feedback session, normal; FV, feedback session, video; TN, training session, normal; TV, training session, video.
Left to right: subject identifier–initials, changed by convention–(note that one subject, XE, performed the experiment twice, second session 4 days after the first, without re-training), handedness (left/right), gender, AIS, Frankel impairment degree; level of SCI, age, sequence of BCI tasks performed, cross-validation on training set performance, feedback in the best session for that subject (ranging from 1 to 3 sessions), feedback on VR BCI use, classes used for best feedback session, timeout used for BCI feedback by session (^*best session), number of trials for each feedback session and frequencies used (Hz). B2R (represented in bold) are the three BCI sequences of BCI and robot use.
^a Patient OK did not complete the feedback session.
