“Intervertebral Differential Dynamics (IDD) Therapy
Exercise-Based Physical Therapy: Initial Results From a Randomized Controlled Trial.”

Published in American Journal of Physical Medicine and Rehabilitation, March 2006. Study by Emory University
Authors: Michael K. Schaufele, M.D. Michael Newsome, P.T.


Data Analysis:
Patients with chronic low back pain secondary to mild to moderate degenerative disc disease were randomized in a 2:1 ratio to IDD (Intervertebral Differential Dynamics) Therapy® treatment or a standardized program of physical therapy consisting of an exercise-based, function-oriented physical therapy program (PT). The patients had to complete a minimum of 6 treatments over a 6-week period in each group. The primary objective of this study was to compare the changes in functional and pain scores (Oswestry, VAS) in both groups and to assess the safety of IDD Therapy® treatment.


Patients receiving IDD Therapy® treatment for degenerative disc disease instead of the current standard of care experienced 20.3% greater pain relief than the exercise-based physical therapy group.

“Long-Term Effect Analysis of IDD Therapy in Low Back Pain; A Retrospective Clinical Pilot Study.”

Published in American Journal of Pain Management, July, 2005.
Authors: C. Norman Shealy, M.D., Ph.D.; Nirman Koladia, M.D.; Merrill M. Wesemann, M.D.
Patient Population: 33 patients


Analysis:   Patients were administered IDD Therapy® treatment and evaluated using a numeric pain scale three separate times: at the first session, at the last session, and one year after treatment

Mean pain level assessments: at first session: 6.88; at the last session: 2.42, one year after treatment: 1.65.

Conclusions:   IDD Therapy® significantly reduces back pain and continues doing so at least one full year after the treatment has ended.

Published in US Musculoskeletal Review, Issue II, 2006 and European Musculoskeletal Review, September, 2006.

Authors: Dennis McClure, M.D., member of AANS; Bethany Farris, M.D.

Patient population: 415 (including 129 surgical candidates). Patients were asked to rate their pain improvement from two months to two years after IDD Therapy® treatment.



On average one year post-treatment completion of one course of IDD Therapy®.

92% of 129 lumbar surgical candidates successfully avoided surgery with IDD Therapy® treatment.
