A lumber traction device for applying a controlled traction force to particular low back regions of a subject's back by the use of the subject's weight. The device comprises a belt having a predetermined width and length for securement about a subject's abdomino-lumbar region, and impinging upon the lower chest area. An attachment secures the belt about the subject's abdomino-lumbar region. A link chain is connected to each of two antero-lateral connecting points and two postero-lateral connecting points of the belt. Each chain has a connecting frame for securing same to a superior support structure, and an attaching portion for independent adjustable securement to a respective one of the connecting points. The belt and the chains support the subject freely in the air whereby the weight of the subject is caused to apply a traction force to the particular low back region. The method of effecting the controlled traction is also described.
