Abstract: A combination of a treatment device and an anterior support device is disclosed. The combination includes a treatment device having an edge and an attachment member movably secured thereto and an anterior support device having an elongated member which interacts with the attachment member. The anterior support device has first and second pivotable connectors, one being secured to the elongated member and the other to a padded rest. The anterior support device also includes first and second movable rods secured to the first and second pivotable connectors. A second end of the first movable rod is rotatably connected to a second end of the second movable rod and an actuating mechanism is connected to both of the second ends of the rods. The actuating mechanism enables the first and second rods to be locked in a set position to maintain the padded rest in a desired orientation relative to the treatment device.
