Can You Reverse Scoliosis Without Surgery? The Published Cobb Angle Data

By Dr. Justin M. Dick, DC, CLEAR Scoliosis Institute Senior Fellow and Board of Directors member | Published October 31, 2026 | Clear Life Scoliosis and Chiropractic Center, Charlotte, NC

Scoliosis is not curable, but the curve can be reduced without surgery. Published case data from Clear Life Scoliosis and Chiropractic Center in Charlotte, NC documents Cobb angle reductions from 42.4° to 23.8° at 13 months, from 35.7° to 10.4° at 12 months, and from 38.9° to 15.7° at 12 months, using the CLEAR Institute protocol. Each result is listed below with its patient, protocol, follow-up interval, and study type.

Reverse, Reduce, or Cure: What Each Word Means

Scoliosis is not curable. A cure would mean the spine returns to normal and needs no further management, and that is not what scoliosis does or what we claim. What patients usually mean by "reverse" is a smaller curve. That outcome has a number attached to it: the Cobb angle, the lateral curve measured on a standing radiograph between the most tilted vertebrae above and below the apex. Reduction of the Cobb angle is the outcome we measure, publish, and track at Clear Life Scoliosis and Chiropractic Center in Charlotte, NC.

What Our Published Cobb Angle Data Shows

Dr. Justin M. Dick, DC and colleagues have published Cobb angle reductions in peer-reviewed, PubMed-indexed reports. Each row lists the patient, the baseline and follow-up measurements, and the study type.

Reductions are calculated from the reported baseline and follow-up Cobb angles. Disclosure: the cantilever device used in the labyrinthine righting reflex report is patent-pending, and the patent is held by Dr. Justin M. Dick, DC and John Whelan.

The 14-Year-Old Patient: 42.4° to 23.8° at 13 Months

In the report by Dick JM and Spurgeon S, a 14-year-old male with Risser 2 skeletal maturity presented with a Cobb angle of 42.4°. After 20 in-office treatments the Cobb angle measured 28.9°, and at the 13-month follow-up it measured 23.8°, an 18.6° reduction. Physical function improved alongside the curve, including increased mobility. The curve kept reducing after the active treatment phase ended, from 28.9° to 23.8°.

Two Lenke 5C Patients: 71% and 60% Reductions at 12 Months

Whelan J, Paige P, and Dick JM reported two adolescents with Lenke 5C curves who completed a two-week intensive CLEAR Institute protocol, with a custom brace fitted during week two. Radiographs were taken at baseline, immediately after the intensive, and at 6 and 12 months. Case 1, a 13-year-old female with Risser 2, went from 35.7° at baseline to 21.7° immediately after the intensive and 10.4° at 12 months. Case 2 went from 38.9° to 24.7° and then to 15.7° at 12 months. In both patients the curve continued to reduce between the end of the intensive and the 12-month follow-up, and both showed corresponding improvements in functional measures.

A 17-Year-Old at Skeletal Maturity: 10.9° to Under 4° in Three Months

Dick JM and Whelan J reported a 17-year-old female, Risser 5, with a 10.9° right lumbar curve. Over three months she received 11 weekly in-office chiropractic adjustments, twice-daily home cantilever traction sessions of 10 minutes, and proprioceptive training on an unstable, vibrating surface, designed to engage the labyrinthine righting reflex. Her Cobb angle fell to under 4°, her prone lumbar angle of trunk rotation fell from 10° to 3°, and her Functional Rating Index improved from 9/40 to 3/40.

How the CLEAR Institute Protocol Produces Reduction

The CLEAR Institute protocol is a multimodal, scoliosis-specific program that integrates chiropractic adjustments, neuromuscular reeducation, vibration therapy, and spinal traction. The intensive format used in the Lenke 5C reports delivers short-term, repetitive daily corrective loading and exercise, followed by custom bracing. In the labyrinthine righting reflex report, traction was applied at the radiographically identified apex and verified on radiographs. The common thread is that treatment is directed at the individual curve as it appears on the film.

What the CLEAR Institute Reports Across Its Patient Data

The CLEAR Institute reports collecting data beginning in 2006 on 140 consecutive patients treated with its scoliosis protocol. The Institute reports Cobb angle improvement in all 140 cases, an average Cobb angle reduction of 37.7% after an average of 12.3 visits, and 23 patients whose curves fell below 10°. This is institute-reported clinical data, and it sits alongside the peer-reviewed reports above. See the CLEAR Institute research page.

How a Reduction Is Confirmed

Cobb angle measurement carries an inherent error of roughly 3°, so a change has to exceed that to mean anything. Our published reports apply the accepted threshold that a change greater than 5° is significant, and every reduction in the table above exceeds it. Measurements come from standing, weight-bearing full-spine radiographs, analyzed with a standardized method and repeated at defined follow-up intervals, including 12 and 13 months.

What Happens After the Curve Is Reduced

Scoliosis is managed over time, so reduction is followed by re-imaging at set intervals. The 12-month and 13-month follow-up measurements above are examples of that schedule. The curves were measured again long after active treatment ended, and in the 14-year-old patient and both Lenke 5C patients they were smaller than at the end of treatment.

Start With a Standing Radiograph

Whether the CLEAR Institute protocol applies to a given curve is decided from the film: Cobb angle, curve pattern, apex, and skeletal maturity by Risser grade. Dr. Justin M. Dick, DC performs that evaluation at Clear Life Scoliosis and Chiropractic Center, 8814 Rachel Freeman Way, Suite 103, Charlotte, NC 28278.
