About this study

The purpose of this study is to compare the efficacy on low back pain intensity at 6 months after randomization of a custom-molded lumbar-sacral orthosis as an add-on therapy to usual care in people with painful adult degenerative scoliosis.

Read the detailed description

Adult degenerative scoliosis is a spinal deformity that appears during adulthood, usually after 50 years, on a previous aligned spine or on an idiopathic scoliosis, due to a cascade of degenerative changes. Adult degenerative scoliosis is more prevalent in women than in men and affects up to 40% of adults aged 65 years and older. Overall, 60 to 80% of patients with adult degenerative scoliosis suffer from low back pain. Apart from analgesics, spinal glucocorticoid injections and physiotherapy, the 2 therapeutic options are bracing and spinal surgery.

Recent literature has suggested better outcomes with surgery than with conservative care. However, the level of evidence was low and the use of bracing in the conservative approach was not specifically evaluated. Therefore, good quality studies assessing bracing efficacy in adult degenerative scoliosis are lacking, explaining in part why many physicians do not offer it as a first-line therapeutic option and instead refer patients to surgery. In a retrospective study of 38 patients with adult degenerative scoliosis, the use of a custom-molded lumbar-sacral orthosis, for a minimum of 6h/d, was associated with a reduction in curve progression as measured with the Cobb angle and with an improvement in pain and activity limitations, at 5-year follow-up.

We hypothesize that a custom-molded lumbar-sacral orthosis as an add-on therapy to usual care (i.e. a standardized prescription of 20 outpatient physiotherapy sessions) could decrease symptoms in people with painful adult degenerative scoliosis as compared to usual care.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Custom-molded lumbar-sacral orthosisDevice

    A custom-molded lumbar-sacral orthosis made according to the Vésinet method associated with measures designed to enhance adherence based on goal-setting techniques (i.e. personalized advice, self-determination of the wearing time, hotline) techniques and monitoring of adherence using a temperature sensor chip to provide feedbacks to participants on the wearing time at follow-up visits, and usual care (i.e. a standardized prescription of 20 outpatient physiotherapy sessions including active self-correction, spinal muscle strengthening, spine and lower limb stretching and learning of home-based exercises).

  • Usual CareOther

    Usual care consisting in a standardized prescription of 20 outpatient physiotherapy sessions including active self-correction, spinal muscle strengthening, spine and lower limb stretching and learning of home-based exercises

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Low back pain intensity

    Mean variation from baseline in low back pain intensity at 6 months after randomization, using a self-adminitred 11-point numeric rating scale

    Measured: 6 months after randomization

Secondary outcomes (6)
  1. Low back pain intensity

    Mean variation from baseline in low back pain intensity at 12 and 24 months after randomization, using a self-adminitred 11-point numeric rating scale (0, no pain and 100, maximal pain in 10-point increments)

    Measured: 12 and 24 months after randomization

  2. Spine-specific activity limitations

    Mean variation in spine-specific activity limitations using the self-administered Oswestry Disability Index (ODI, 0 no limitations and 100, maximal limitations) at 6, 12 and 24 months,

    Measured: 6,12 and 24 months

  3. Health-related quality of life

    Mean variation in health-related quality of life using the self-administered EQ-5D-5L questionnaire (1, having no problems and 5, having extreme problems) at 6, 12 and 24 months,

    Measured: 6,12 and 24 months

  4. Progression of the lumbar curve

    Percentage of participants with a progression of the lumbar curve, as measured by the Cobb angle, greater than 5° on an EOS® full-spine X-ray standardized posteroanterior X-ray in standing, weight-bearing position (EOS® full-spine X-ray system) at 12 and 24 months

    Measured: 12 and 24 months

  5. Spine surgery

    Percentage of participants who self-report spine surgery at 24 months

    Measured: 24 months

  6. Cost-utility ratio

    Estimated total costs and incremental cost-utility ratio at 24 months

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Custom-molded lumbar-sacral orthosis in people with Degenerative Scoliosis and Scoliosis Idiopathic, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 1 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Christelle NGUYEN, MD, PhD (01 58 41 29 95 ext. +33, christelle.nguyen2@aphp.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Low back pain intensity (time frame: 6 months after randomization). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 May 2026.
