Ipsilateral and mirror decoders built with data from the two experiments: (a) Ipsilateral and (b) mirror decoders from sessions S1-S3 of the experiment with healthy participants. (c) Mirror decoders from sessions S4-S7 of the experiment with healthy participants. (d) Ipsilateral and mirror decoders from the experiment with stroke patients. For the four diagrams, the information to the left of the red arrow refers to the calibration data and the one the arrow is pointing to, to the testing data. The green background color indicates that the decoders are task-specific, whereas the blue background color signifies that the decoders where general. The tasks that were used for calibrating and testing are displayed at the bottom left and right of the squared box of each decoder respectively. For the task-specific decoders, Ti indicates that a separate decoder was built for each of the four tasks Ti, i = 1–4. For the general decoders, Tk-Tj means that all the tasks from k to j were used for calibrating and/or testing a decoder. FM stands for the free movement task. The mirror decoder of the experiment with stroke patients specifies the tasks employed for each of the patients P1 and P2. The “Left” and “Right” labels specify which limb the participants wore the exoskeleton on during that session. Finally, the “Active-Active”, “Active-Compliant” and “Compliant-Compliant” labels inform about the compliance conditions under which the “calibration- testing” data was recorded.
