Statistics were done using an independent t-test unless otherwise indicated; ^A Statistically tested using Mann Whitney U test; Bold indicates p-value below 0.05; For the AB group, intact leg indicated the dominant leg and the prosthetic leg indicated the non-dominant leg. AB: able-bodied persons; TFA: persons with a transfemoral amputation; BAP: bone-anchored prosthesis group; SSP: socket-suspended prosthesis group; km/h: kilometer per hour; sec.: seconds; cm: centimetre; SD: standard deviation; MoS: Margin of stability
