The aim of this study was to investigate the function of the intact limb of the trans-femoral prosthesis users in terms of joint movements, moments and powers in the saggital plane when they change walking speeds and when they change the swing phase control of the knee joint of their prosthesis. Five trans-femoral amputees and ten able-bodied subjects walked at 40 meters per minutes (m/min), 60m/min, 80m/min, 90m/min (amputees only, maximum speed for the amputees,) and 100m/min (able-bodied subjects only) along a walkway. All the amputees used the Intelligent Knee Joint. They had finished sufficient gait training to use this type of the prosthesis. They walked with their Intelligent function active (IPOn) and inactive (IPOff). When the Intelligent Knee with IPOff was applied, it is the same as the amputees using the conventional prosthetic knee, with a pneumatic swing phase control cylinder. As a result, joint moments and powers increased according to the increase of speed which was similar to those of able-bodied subjects. Nevertheless, the knee joint moment of the intact limb was larger than the able-bodied subjects, but there was no difference in the intact limb function between IPOn and OPOff.
