2PD assessment. Summary results for the (a) two-point discrimination (2PD) while sitting (cyan) and walking (orange). The box plots summarize the results of able-bodied participants (n = 11), while each participant with a lower-limb amputation is shown individually using attributed markers. Average 2PDs for sitting (b) and walking (c) in able-bodied participants are displayed on the electrode drawings. The change in 2PD (d) between walking and sitting is shown for each participant in the bar plots. Able-bodied participants are displayed in grey, the black bar is the mean ± std for the able-bodied group, while participants with transfemoral and transtibial amputation are in purple and dark blue, respectively. A positive value indicates that the variables were higher during walking vs. sitting (and vice versa). Annotations: “AB” = Able-body participants; “S#” = Able-bodied participant, followed by the number; “TF#” = Participant with a transfemoral amputation, followed by the number; “TT#” = Participant with transtibial amputation, followed by the number; “2PD”: two-point discrimination; ***p < 0.001
