An apparatus and procedure for disabled, impaired or handicapped persons in reaching or maintaining a standing or partially standing position. The apparatus includes a knee support and a movable torso support that is connected to an actuator arrangement. The actuator arrangement moves the torso support in a vertical range of positions independently of the horizontal position of the torso support and in a horizontal range of positions independently of the vertical position of the torso support. The user engages the torso support during the raising movement during which the torso support moves simultaneously forward and upward until he is substantially standing whilst leaning forward over the torso support (and vice versa for the lowering procedure). The torso support can also be rotated, independently of the vertical and horizontal position of the torso support. The apparatus is provided with a load sensing system monitoring self-participation of the user.
