FIGURE 7

Effect of training on RT/Distance curves (quadratic fitting function) in the VTI experiment, when the participant was tested with the healthy right limb (green) and with the more trained prosthesis (red) in the PRE session (lighter colors) and in the POST_NI session (darker colors). Somatosensory stimulation was always delivered non-invasively. Values are means (dots) ± SEM (bars). The healthy hand underwent a general speeding of RTs for all the tested distances yet maintaining a similar RT/Distance pattern, while the prosthesis changed the pattern of the RT/distance with a decrease of RTs in far space. This suggests an extension of the PPS induced by the embodiment of the prosthesis.
