 3 Procedure and design The experiment was composed of three trials at each of the two IDs: 2 and 4 ID 4 had two kinds of measurement - ID4a and ID4b, and the participants performed the tasks individually in a room, with only the evaluator present, seated on a chair or their own wheelchair, which was adjusted in height according to the needs of the individual. A footrest was available, when necessary. The computer was placed on a table, and each participant was given instructions and presented with the task, in which the individual, after hearing an alarm from the computer, was required to click with an external mouse cursor on two parallel bars which were arranged vertically, intermittently, with the greatest speed and accuracy possible, for a period of 10 seconds, followed by a second alarm which indicated the end of the attempt.
