The pneumatic lumbar traction device comprises two separable parts, namely an upper hollow shell and a lower plate or frame. The plate or frame has a pneumatically operated piston and cylinder mechanism located centrally thereof with a piston rod extending outwardly to engage a guided bar guided in a guideway mounted to the plate or frame. The guided bar extends outwardly of a foot end of the hollow shell and the plate or frame has an outer perimeter. The hollow shell has an inner perimeter which is sized to seat over and around the outer perimeter of the plate or frame, such that the outer perimeter of the plate or frame can bear against the inner perimeter of said hollow shell at a head end of the device when traction is placed on the lumbar region of a users back. The hollow shell has the foot end and a head end. The opening at the foot end allows the guided bar to extend therethrough. Further the hollow shell has an upper smooth surface on which a user will lie and a chest strap is fixed to the upper surface of the hollow shell. A pelvic traction belt is adapted to be received around the pelvic area of a user and has at least one strap extending outwardly toward a foot end of the device. And a T-bar, having a lower portion thereof adapted to be fixed to an outer end of the guided bar and an upper portion thereof adapted to hold at least one strap, extends from the pelvic traction belt.
