A spinal decompression machine includes a portable frame, a user support element, a laterally positioned handle extending from the frame, and a drive mechanism operatively coupled to the handle. A force bar operatively coupled to the drive mechanism extends longitudinally beyond a longitudinal end of the frame. A harness is attached to the first force bar. The drive mechanism causes the force bar to move longitudinally upon rotation of the handle. A method of providing traction includes positioning a person in a face up position upon the user support element, attaching a harness to a neck or pelvis of the person, the harness attached to a cervical traction bar or a pelvic traction bar, and moving the cervical fraction bar and pelvic fraction bar simultaneously in a common longitudinal direction by moving a handle.
