Figure 5.

Phasic EDA maps over the complete walking course for participants with (A) transfemoral LLA or (B) transtibial LLA and, (C) a control participant. The participant for the transfemoral group (the group with the highest level of amputation) shows scores on clinical measures (ABC, PLUS-M, and AMP PRO) that are representative of the transfemoral group mean score in each clinical measure. In contrast, the representative participants for both the transtibial and control groups have the lowest ABC score of each respective group, suggestive of the lowest reported balance confidence (ABC) and balance performance of each group. Representative of the transfemoral group, the participant with transfemoral LLA demonstrated more notable phasic EDA responses during tasks compared to the participant with transtibial LLA or controls (despite similarly rated balance confidence). The locations of each walking tasks are indicated by boxed labels on each of the maps. Only the participant with transfemoral LLA demonstrates heightened phasic activity (blue-purple colour) during each of the three walking tasks during the walking course.
