Perceived controllability of the system. (A) Controllability of the system, self-assessed in the questionnaire at the end of the experiment. Subjects reported mixed opinions about the controllability of the prosthetic system. No statistical evidence supported the modest improvement of the perceived controllability provided by the static training. (B) The subjects who started the experiment with dynamic training and continued with static training (D-S) reported improved system controllability for the second condition tested. (C) Those who tried the static training first (S-D) experienced equivalent controllability in both conditions.
