About this study

Official title: Effectiveness of YOga in Patients With Chronic Low BACK Pain and Poor PROgnosis (YOBACK-PRO Trial): a Randomized Controlled Trial

The goal of this clinical trial is to investigate the effectiveness of yoga for patients with chronic low back pain and high risk of poor prognosis. The main question it aims to answer is:

  • In patients with back pain and high risk of poor prognosis, what is the effectiveness of yoga plus education on reducing pain and disability compared to a control group receiving education alone?

A total of 110 patients with chronic low back pain and classified as high risk of poor prognosis according to the Orebro Musculoskeletal Pain Screening Questionnaire (i.e. score ≥ 50 points out of 100) will be recruited for this study. Participants will be randomized into two groups: yoga and control. The yoga group will receive a 3-month course of yoga program consisting of two sessions per week and 3 educational classes. The control group will receive 3 educational classes over a 12-week period. Outcome measures will be assessed at baseline, at post-intervention (i.e. 3-months post randomization) and at 6-month follow up (i.e. 6-months post randomization).

What participants receive

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

  • ControlOther

    Each educational class will last for 1 hour and consists of evidence-based information about low back pain, including, for example, self-management strategies, pain education, reassurance and common misconceptions about back pain.

  • YogaOther

    Participants in the intervention group will receive, in addition to the educational classes, a course of yoga program led by certified yoga instructors. The program consists of a 60-min group session with up to 10 participants, delivered twice a week for 12 weeks.

Where is the study taking place?

The record lists 1 site in Brazil. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Disability (time frame: Post-intervention (i.e. 3 months after randomisation)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05953155, which also lists 1 linked publication.

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 14 Sep 2026; AzTrials last refreshed its copy on 7 Nov 2026.
