Research Results for the Orthotrac Pneumatic Vest

Preliminary research indicates that for appropriate patients, significant functional improvement can be expected with use of this device.

The following research results are currently available:

  1. In a single group, prospective, pilot study1 of over 200 patients, presented at the May 2003 World Federation of Chiropractic Meeting, over 70.4% (p<0.01) of patients realized significant functional improvement (measured using the SF36), and decreased pain (28.1%, p<0.01), measured with the Visual Analog Scale (VAS), within 8 weeks of using the Orthotrac device.

  2. Results from an intradiscal pressure study2 at the Cleveland Clinic were presented at the May 2003 Spine Arthroplasty Society Meeting. Study results showed a 23% (p<0.01) decrease in intradiscal pressure at the L4-L5 segment when the Orthotrac vest was fully inflated.

  3. Preliminary data from a prospective, randomized, controlled, blinded study3 at the Texas Back Institute demonstrates significant effects from the Orthotrac when patients are selected according to the four criteria described on page 1 of this article.

Preliminary data from a prospective, randomized, controlled, blinded study3 at the Texas Back Institute demonstrates significant effects from the Orthotrac when patients are selected according to the four criteria described on page 1 of this article.

In this study, the Orthotrac group had 6 times greater reduction in back pain, and an 8 times greater reduction in leg pain (VAS, p < 0.0003). Activities of daily living (using the Oswestry scale) improved 28 points versus 7.3 (p < 0.019).

The SF-36 mental health score increased by 24 points for the Orthotrac vest group, but decreased 13 points for the control group (p <0.06). Also, flexion improved 20 degrees in the mean for the Orthotrac group and 5.2 degrees for the control group.

All results in this study were measured at 12 weeks from baseline.

The effectiveness of this device is still being researched. At the time of this article, there are no peer-reviewed published clinical studies of the effectiveness of the Orthotrac pneumatic vest in relieving lower back pain and/or leg pain. However, the above studies indicate that the device is showing potential to relieve symptoms for patients who meet specific criteria.
