About this study

Official title: Prospective, Comparative, Randomized Study of the Effectiveness of Shock Wave Treatment in Myofascial Pain Syndrome in Low Back Pain

The purpose of this study is to evaluate the efficacy of treatment of radial shockwave in myofascial pain syndrome in the lumbar region compared to placebo through questionnaires and imaging exams.

Read the detailed description

BACKGROUND: Extracorporeal shockwave treatment has been used widely for musculoskeletal conditions, however no randomized controlled trial are available about its use for chronic low back pain with myofascial pain syndrome (MPS).

HYPOTHESIS: Radial extracorporeal shockwave treatment (rESWT) improves pain intensity and functional disability compared with placebo in patients with chronic low back pain due to MPS.

STUDY DESIGN: Randomized controlled clinical trial METHODS: A prospective, randomized, double-blind, placebo-controlled study will be carried out on 40 patients who has moderate to severe pain (VAS > 4) for more than 6 months, despite 6 weeks of conservative treatment with antidepressants associated with rehabilitation. Six interventions of rESWT (3-4 bar; 1000 impulses per trigger point (TP) or 2500 impulses per muscle) will be compared with placebo. The outcome measures were pain visual analogue scale (VAS), Oswestry Disability Index, Short-form McGill Pain Questionnaire, Roland Morris Disability Questionnaire and the temperature of the treated area will be evaluated with Thermography. The assessments will be apply before treatment, after conservative treatment, 6 and 12 weeks after rESWT.

What is being measured

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

  1. Evidence of pain relief by visual analogue scale (VAS) of radial extracorporeal shock waves in myofascial pain syndrome in the lumbar and gluteal region compared to placebo

    The outcome will be assessed by Visual Analogue Scale (VAS)

    Measured: 12 weeks after the last session of shockwave

Questions about this trial

What is this clinical trial studying?

A study testing Swiss DolorClast® CLASSIC applicator in people with Myofascial Pain Syndromes and Low Back Pain, run by University of Sao Paulo at 1 site in Brazil.

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 16 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: finished, as of the sponsor's last update on 30 Apr 2019. 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 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. Some participants in this study may receive a placebo. 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?

Evidence of pain relief by visual analogue scale (VAS) of radial extracorporeal shock waves in myofascial pain syndrome in the lumbar and gluteal region compared to placebo (time frame: 12 weeks after the last session of shockwave). 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 30 Apr 2019.
