Questionnaire responses in the control group (n = 26) and patient group (n = 16). In the graph, each question is represented by bars with color-coded answers. The numbers of positive (negative) ratings are shown on the positive (negative) vertical axis. Columns I–V show the ratings of the BCET features: confidence in control (I), activation (II), information on bed setup (III), position selection (IV), and clarity of control (V). Positive ratings predominate in these categories in both groups. Six of 16 patients indicated a preference for an alternative control over the presented one (column VI). Pain during the testing (column VII) was indicated by a total of 4 participants (1 control and 3 patients) and rated as mild. The answers were on a 5-level scale: strongly supportive for BCET (++, green bars), likely supportive (+, blue bars), not sure (gray), likely unsupportive (–, orange bars), and strongly unsupportive (–, yellow bars)
