<p>The invention disclosed is an exercise device comprising a frame holding a seat above the floor that has a resistance loaded backrest for the purpose of rehabilitating atrophied spinal support muscle through progressive resistance exercise whil e the spine is under pain alleviating traction. The backrest is resistance loaded for both traction, and extension resistance or flexion resistance. This makes needed exercise possible for those who are hindered from such therapy by spinal compressive related pain. The exercise resistance is transmitted to the patient via a horizontal axis backrest, and can be weighted either positively for back resistance, or negatively for abdominal resistanc e, at the same time traction is applied from a backrest suspension system applying resistan ce to the user attached to it in the direction that decompresses the spine.</p> |
