Brief Summary:
This pilot study will evaluate the effectiveness and safety of the Axiom Worldwide DRX9000 for active treatment of chronic low back pain.

Condition or disease Intervention/treatment Phase
Low Back Pain Device: DRX9000™ Phase 2

Detailed Description:
Currently, there are no prospective safety and/or outcomes studies utilizing the DRX9000™ in the peer-reviewed medical literature. There are published trials utilizing similar machines which provided evidence in support of the FDA granted indications for use spinal decompression and of the DRX9000™. Axiom Worldwide has determined it will be of benefit to the continuing medical care of patients and a furthering of the scientific knowledge of the treatment of LBP to complete such a prospective evaluation using a standardized treatment protocol. This study will therefore attempt to establish and validate the safety and efficacy of this computerized spinal decompression system in the treatment of LBP and sciatica.

Arm Intervention/treatment
Experimental: DRX Group
Patients using the device DRX9000™.
Device: DRX9000™
Device is designed to apply spinal decompressive forces.

Primary Outcome Measures :
  1. Post-treatment Numerical Pain Intensity Rating Scale (VRS), Which is a Scale From 0-10 (0=no Pain, 10= Worst Pain) [ Time Frame: Six weeks ]
    The numerical results of the post-treatment verbal numerical pain intensity rating scale (VRS) following completion of a standard six week series of 20 DRX9000 treatments.

Secondary Outcome Measures :
  1. Recurrence for Significant (VRS Greater Than or Equal to 4) LBP Following Completion of 6 Weeks of DRX9000 Treatment. [ Time Frame: Six weeks ]
    The number of Subjects reporting VRS greater than or equal to 4 for LBP following completion of 6 weeks of DRX9000 treatment will be recorded.

  2. Change in Functional Capacity From Baseline to Six Weeks (The Revised Oswestry Pain Questionaire) [ Time Frame: Six weeks ]
    Subject functional capacity following 6 weeks of DRX9000 treatment will be measured as a numerical score by the Revised Oswestry Pain Questionaire (scale 0-50, 0=pain without effects). Functional capacity was assessed at Baseline, 3 Weeks and 6 Weeks.

  3. Patient's Satisfaction With Treatment Procedures Following 6 Weeks of DRX9000 Treatment. [ Time Frame: Six weeks ]
    Patient's satisfaction with treatment procedures following 6 weeks of DRX9000 treatment was measured on a scale from 0-10 (0= very unsatisfied, 10=very satisfied).

  4. Number of Adverse Events Following 6 Weeks of DRX9000 Treatment. [ Time Frame: Six weeks ]
    Total number of adverse events reported following 6 weeks of DRX9000 treatment.

  5. Number of Patients Who Withdraw From Study. [ Time Frame: 6 weeks ]
    Total number of patients who withdrew during the 6 weeks of treatment.
