About this study

Official title: The Effect of Medial Branch Radiofrequency Ablation on Functional Spinal Stability and Lumbar Multifidi Muscle Architecture Assessed by Magnetic Resonance Imaging and Ultrasound Imaging

The purpose of this study is to evaluate the effects of lumbar medial branch radiofrequency ablation (RFA) on lumbar multifidi muscle size and clinical spinal stability. Specifically, this study is designed to highlight the comparison of multifidi muscle architecture using ultrasound imaging (USI) and MRI before and after lumbar medial branch RFA. This study will also include a commonly utilized functional assessment of the lumbar spine to evaluate the effects of RFA on lumbar spinal stability.

Read the detailed description

Radiofrequency ablation (RFA) for the lumbar spine (lower back) is a procedure used to treat lower back pain secondary to facet arthritis. The procedure ablates (burns) a small nerve that goes to the arthritic joint in the back. This nerve also innervates a muscle called the multifidus, thought to be important for lumbar stability. The investigators are conducting a study to evaluate if RFA has any impact on multifidi size, spinal stability, and overall function. The tools the investigators will be using to assess the multifidi muscles are musculoskeletal ultrasound, MRI, physical therapy assessment, and functional questionnaires. The goal of the study is to determine if RFA impacts the multifidi in a clinically significant fashion, causing atrophy, spinal instability, and/or functional decline.

What participants receive

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

  • Patients undergo ultrasound and lumbar MRIDiagnostic test

    Patients undergo ultrasound, physical therapy exam and MRI before and after the radiofrequency ablation procedure that they are getting as part of their regular care.

What is being measured

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

  1. Percentage Change in Volume of multifidus muscle on MRI

    Analysis will include volumetric measurements of the multifidi as well as volumetric assessments of the muscle with fat subtracted.

    Measured: Up to 3 months after radiofrequency ablation procedure

  2. Percentage Change in Cross Sectional Area of Multifidi

    Area will be measured by MRI scan.

    Measured: Up to 3 months after radiofrequency ablation procedure

Secondary outcomes (2)
  1. Score on Numeric Pain Rating Scale (NPRS)

    The Numeric Pain Rating Scale (NPRS) is a unidimensional measure of pain intensity in adults. Respondents are asked to select a whole number (0-10 integers) that best reflects the intensity of his/her pain. The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable").

    Measured: Up to 3 months after radiofrequency ablation procedure

  2. Percentage Score on the Modified Oswestry Disability Index

    This is a patient-completed questionnaire which gives a subjective percentage score of level of function (disability) in activities of daily living in those rehabilitating from low back pain. It examines perceived level of disability in 10 everyday activities of daily living, which each statement scored from 0 (no disability) to 5 (worst pain). An aggregate score (percentage) is then calculated, with 0% indicating no disability to 100%, indicating crippled or bed-bound.

    Measured: Up to 3 months after radiofrequency ablation procedure

Questions about this trial

What is this clinical trial studying?

An observational study of Spondylosis and Osteoarthritis, run by Columbia University at 1 site in United States.

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 4 inclusion and 9 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 10 Jul 2020. 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 United States. 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?

Percentage Change in Volume of multifidus muscle on MRI (time frame: Up to 3 months after radiofrequency ablation procedure). The study lists 2 primary outcomes in all. 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 10 Jul 2020.
