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.

Condition Intervention
Chronic Low Back Pain Device: DRX9000

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Retrospective
Official Title: Restoration of Disk Height Through Non-Invasive Spinal Decompression is Associated With Decreased Discogenic Low-Back Pain: A Retrospective Cohort Study

Groups/Cohorts Assigned Interventions
DRX9000 Device: DRX9000
DRX9000 - non-invasive spinal decompression. Treatments 28 min 5 x/wk x 2wks, 3x/wk x 2 wks, 2x/wk x 2 wks for a total of 20 treatments in a 6-week period


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
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).
