Clinical Trial Outcomes

Cox Technic clinical trial outcomes are documented. Randomized control trials compared flexion distraction with medical conservative treatment. Low back pain and leg pain patients as well as neck pain and arm pain patients were followed.
 
The Low Back and Leg Pain Study
 
European Spine Journal reports on a comparison study of flexion-distraction to medical conservative active-exercise therapy in treating chronic pain patients. Participating, eligible patients were randomized to one of two treatment groups: flexion distraction only or medical conservative (active exercise program) only.
 
Statistics were gathered on each participant as to their pain's source, duration, symptomatology, etc.
 
The study revealed chronic low back pain patients, including the more difficult and painful radiculopathy (pain that extends down the leg and/or foot) patients did statistically better with flexion distraction.

Physical therapy subjects attended significantly more health care visits in the year following care than those receiving chiropractic care:
  • 38% of flexion distraction patients
  • 54% of physical therapy patients

  • Flexion distraction chiropractic manipulation was found more effective in reducing pain for 1 year when compared to a form of physical therapy
The Neck Pain and Arm Pain Study
 
Participating, eligible patients were randomized to one of three treatment groups: flexion distraction only, medical conservative (active exercise program) only, or a combination group of both therapies.
 
There was a clinically significant difference in the outcomes, but not a statistical difference in the outcomes. As expected, patients receiving the combination of treatments had significant improvement in pain and disability.
 
This study was presented at the World Federation of Chiropractic, 8th Biennial Conference, Sydney Australia, June 16-18, 2005, by Dr. Ram Gudavalli.
 
These findings and others are really expanding the teaching of how Cox Technic for cervical spine is taught and applied clinically!

In this cadaveric study we observed decreases in IDP in the lower cervical spine during a chiropractic MCD procedure in prone position. Based on the maximum number of specimens DC1 has done, moving flexion and traction seem to reduce more IDP, followed by neutral traction, fixed flexion and tractions, and generalized traction. Although the doctors of chiropractic in this study demonstrated good intraclinician reliability, the magnitude of traction forces varied. Larger powered studies should be undertaken to determine if these decreases in IDP are significant depending on the doctor, contact location, and the different traction procedures. Also, the clinical significance of these differences is unknown.

This paper reports on the development of real‐time feedback on the applied forces during the application of the flexion‐distraction procedure. In this pilot study we measured the forces applied by experienced DCs as well as novice DCs in using this procedure. After a brief training with real‐time feedback novice DCs have improved on the magnitude of the applied forces. This real‐time feedback technology is promising to do systematic studies in training DCs during the application of this procedure.

Clinician proficiency in delivering cervical traction forces within three specified ranges (low force, less than 20 N; medium force, 21–50 N; and high force 51–100 N). Clinicians delivered manual cervical distraction treatments within the prescribed traction force ranges 75% of the time without visual feedback and 97% of the time with visual feedback. This study
demonstrates that doctors of chiropractic can successfully deliver prescribed traction forces while treating neck pain patients, enabling the capability to conduct force‐based dose response clinical studies.

This pilot study demonstrated the feasibility of a clinical trial protocol and the utility of a traction‐based, minimal intervention as an attention‐touch control for future efficacy trials of MCD for patients with neck pain.
