While there were no significant differences in oxygen consumption (VO₂) between prosthesis users and unimpaired groups at any time point (p > 0.05), VO₂ increased significantly in both groups from rest, to minute 1, and to minute 2 (p < 0.001) during both walking tests. Note: 2MWT: 2 minute walk test, 6MWT: 6 minute walk test.
