18. A method for initiating and implementing a stair-climbing mode in a passive prosthetic knee joint connected to a prosthetic leg unit including a prosthetic foot comprising:
-
detecting a low-torque lift of the prosthetic foot; initiating a lift phase, in which a flexion damping level of the knee joint is reduced to a level below that which is used for walking on level ground; detecting a placement of the prosthetic foot; and initiating a lowering phase, in which the flexion damping level is increased to a level above that which is used for walking on level ground. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
