The investigators hypothesize that a 6-week treatment of non-invasive spinal decompression reduces discogenic low back pain (LBP), increases lumbar disk height, and that an increase in lumbar disc height is associated with decreased LBP.

Study Population
Primary care clinic

Inclusion Criteria:

  • at least 18 years of age;
  • consented for the 6 weeks treatment protocol;
  • presented with discogenic low back pain of at least 3 out of 10; AND
  • current CT scan not older than 2 months.

Exclusion Criteria:

  • metastatic cancer;
  • previous spinal fusion or placement of stabilization hardware;
  • instrumentation or artificial discs;
  • neurologic motor deficits, bladder, or sexual dysfunction;
  • alcohol or drug abuse; OR
  • litigation for a health-related claim (in process or pending for workers' compensation or personal injury).

Limitations of the spinal decompression system also led to the exclusion of patients with extremes of height (< 147 cm or > 203 cm) and body weight (> 136 kg).
