A simple, lightweight, portable, lumbar spinal distraction device is provided which employs a frame having concave left and right hand upper leg contacting members for asserting forces against substantially vertically oriented left and right upper leg portions of a user assuming a substantially horizontal position. The user pushes the portable frame forward by manually grasping a pair of handles, causing the left and right contacting members to press against the vertically oriented left and right upper leg portions respectively. Increased unilateral traction ability is produced by simply having the user apply extra force to one handle or the other. This will permit users suffering from unilateral pain in the buttocks, hip or leg to obtain a little extra pressure on the symptomatic side. Anyone who has suffered low back pain can relate to the fact that some days the pain feels more right sided and some days more left sided.
