PAKback 637

The PAKback 637 represents the next generation in Lumbar-Sacral Orthotics.

The PAKback 637 is a non-narcotic/non-surgical alternative for treating patients with moderate to severe low back pain. The use of the anterior, posterior and sagittal panels create intracavitary pressure to unload the lumbar discs. The removable gel pack can be used as heat therapy for chronic pain, and cold therapy for acute pain.

Features Include:

  • Gel pack can be used for hot or cold therapy either with or without posterior panel
  • Reduces load on intervertebral discs which assist in pain relief
  • Rigid anterior panel creates true hydrostatic lift of lower abdominal muscles
  • Ergonomic design creates better fit and greater comfort
  • Reduces the need for pain medication, tranquilizers and steroids
  • Allows patients to maintain a better quality of life
