‘Open-loop’ and ‘closed-loop’ performances in TR. a Variability of sensor data placed on the middle and little finger of the robotic hand during the shape recognition task (SRT). The sensors’ profiles for 90 trials of Subject 1 and 2 are averages ± S.E.M. (shaded area). Profiles are plotted from threshold to saturation. b Comparison between open-loop and closed-loop (wearing the bidirectional hand prosthesis) performances in TR are reported for the same DeltaTR (1.5 s) for Subject 1 & 2. They are not statistically different (p > 0.05, Fisher’s exact test, 90 repetitions for each condition were considered). c Over time performances of open and closed loop configurations are shown for TR for both subjects. No statistical difference was found among different sessions in all conditions (p > 0.05, Fisher’s exact test)
