Table 1.

Means and standard deviations of demographic data and functional scores of the 2 patients groups at the time of enrolment in the study. In the experimental group, brain activity moved the orthoses; the control group received random orthosis movements not linked to control of oscillatory brain activity. Lesion side indicates damaged hemisphere. Motor part of the modified upper limb cFMA (hand and arm parts combined having a maximum score of 54 points) and Goal Attainment Scale (GAS) scores are presented for both groups. Training duration indicates the number of runs during BMI training. One run contains 11 trials of 5 s in which the patients were able to move the orthosis using the brain–machine interface system. None of the differences of baseline measures between the experimental and control groups was significant
