A frame includes a front segment extending across an anterior side of a human and a back segment extending across a posterior side of the human in a fixed spatial relationship. A clamp bar extends between the front segment and the back segment to interface with a first lateral side of the human at a location between an ilium bone structure and a thoracic cage of the human. A lateral restraint is positioned between the front segment and the back segment and is configured to interface with a second lateral side of the human over an engagement area corresponding to a portion of the thoracic cage of the human. A downward treatment force is applied to the frame at a location opposite the clamp bar from the lateral restraint. The human works to laterally translate their spinal column toward the lateral restraint to maintain the frame in a near-level orientation.
