Dextrose prolotherapy injected into acupuncture points for chronic non-specific low back pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This single-blind, randomized controlled trial will enroll 60 adults with chronic non-specific low back pain and randomly assign them to receive injections of 15% dextrose plus 1% lidocaine or 1% lidocaine alone into predefined acupuncture points. Treatments are delivered in outpatient sessions at a single center and patients will be blinded to group assignment where possible. The study will measure pain and functional outcomes over follow-up to see whether adding hypertonic dextrose (prolotherapy) provides superior or longer-lasting relief. Eligibility allows BMI up to 45 kg/m2 and excludes patients with specific structural spinal disease or neurological deficits.

* Pain, inability to walk, and stiffness in the lumbar spine, persisting for at least three months prior to the study.
* Radiological imaging tests such as MRI or CT and, in cases of clinical suspicion (where appropriate), X-rays with dynamic flexion/extension or whole spine X-rays.
* Signing of written consent prior to the injection of pharmaceutical agents.

Exclusion Criteria:

* Any infection of the skin of the lumbar spine area, such as cellulitis, or periarticular or intra-articular infection or spondylodiscitis during the last 3 months
