Amputees of any activity level can enjoy the stability of the knee, while experiencing smooth and quiet swing phase response. K2 amputees with potential for variable cadence can walk confidently on the knee while developing sound and efficient gait habits. The variable cadence controller allows an unimpeded increase in walking speed by controlling heel rise and attenuating terminal impact. This allows for potential future documentation of variable cadence and prescription of a K3 prosthesis.
