Certain embodiments of the invention relate to increasing the functionality of a transfemoral prosthetic device. In one embodiment, the transfemoral prosthetic device is configured such that the prosthetic knee maintains a load consistent with a healthy knee walking on level ground, while the prosthetic ankle adjusts for the incline or decline. In certain embodiments, adjustments, such as a toe lift function, are automatically performed after about three strides of the transfemoral prosthetic device user and/or when each of the strides has a stride speed of at least about 0.55 meters/second.
