A residual limb model may be a model of a residual limb. A residual limb model may include a residual limb portion and a bladder complementary in shape to the residual limb portion. A prosthesis donning and doffing training system may include a check socket and a residual limb model complementary in shape to the check socket. A method of training in the care of a residual limb may include providing a residual limb model and training in the care of a residual limb using the residual limb model. A method of training in the donning and doffing of a prosthesis may include providing a prosthesis training system and training in the donning and doffing of a prosthesis using the prosthesis training system.
