About this study

Official title: Effect of Neuromuscular Electrical Stimulation Using the StimaWELL 120MTRS System on Multifidus Muscle Morphology and Function in Patients With Chronic Low Back Pain

This study evaluates the effect of a 10-week long intervention with the StimaWELL 120MTRS system on multifidus morphology and function in individuals with chronic low back pain. Half the participants will receive muscle therapy at the device's phasic setting, while half will receive muscle therapy at the device's combined setting. This study also evaluates the acute effect of a single treatment with the StimaWELL 120MTRS on multifidus stiffness in individuals with chronic low back pain.

What is being measured

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

  1. Change in multifidus muscle size (cross-sectional area)

    Multifidus muscle cross-sectional area measurements will be obtained from magnetic resonance imaging (MRI) at L4-L5 and L5-SI spinal levels.

    Measured: Baseline, after 10 weeks

  2. Change in multifidus muscle fat infiltration

    Multifidus muscle fatty infiltration (composition) measurements will be obtained from magnetic resonance imaging (MRI) at L4-L5 and L5-S1 spinal levels

    Measured: Baseline, after 10 weeks

  3. Change in multifidus muscle function (% thickness change)

    Multifidus muscle function, expressed as the % thickness change from a rested to contracted position via prone contralateral arm lifts will be assessed by ultrasound.

    Measured: Baseline, after 10 weeks

  4. Change in multifidus muscle stiffness

    Multifidus muscle stiffness, obtained at rest in a prone position, with prone contralateral arm lifts, and in a standing position, will be assessed by ultrasound (shear-wave elastography)

    Measured: Baseline, after 10 weeks

  5. Change in multifidus muscle stiffness

    Multifidus muscle stiffness, obtained at rest in a prone position, and in a standing position, will be assessed by ultrasound (shear-wave elastography)

    Measured: Before and 15 minutes after 3rd treatment

Secondary outcomes (7)
  1. Change in the Numerical Pain Rating Scale (NPRS) for low back pain intensity at present

    The NPRS measures pain intensity on a scale of 0 - 10, with 0 being no pain, and 10 being the worst pain imaginable

    Measured: Baseline, before and after each treatment, after 10 weeks

  2. Change in the Numerical Pain Rating Scale (NPRS) for low back pain intensity (best and worst pain over previous week)

    The NPRS measures pain intensity on a scale of 0 - 10, with 0 being no pain, and 10 being the worst pain imaginable

    Measured: Baseline, prior to 11th treatment, after 10 weeks

  3. Change in the Numerical Pain Rating Scale (NPRS) for low back pain intensity (sitting and with movement over past 24h)

    The NPRS measures pain intensity on a scale of 0 - 10, with 0 being no pain, and 10 being the worst pain imaginable

    Measured: Baseline, prior to 11th treatment, after 10 weeks

  4. Change in the Numerical Pain Rating Scale (NPRS) for overall leg pain intensity in the past week

    The NPRS measures pain intensity on a scale of 0 - 10, with 0 being no pain, and 10 being the worst pain imaginable

    Measured: Baseline, prior to 11th treatment, after 10 weeks

  5. Change in the Oswestry Disability Index (ODI)

    The ODI is used to measure the participant's level of disability in relation to LBP. It is a 10-item scale in which each item is rated from 0-6. Higher scores indicate greater disability.

    Measured: Baseline, prior to 11th treatment, after 10 weeks

  6. Change in the Pain Catastrophizing Scale (PCS)

    The PCS is a 13-item questionnaire that assesses the participant's level of catastrophizing. Each item is rated from 0-4 for a possible total of 52. Higher scores indicate greater catastrophizing.

    Measured: Baseline, prior to 11th treatment, after 10 weeks

  7. Change in the Brief Pain Inventory - Interference (BPI)

    The BPI-I is a 7-item questionnaire that measures how pain interferes with activities of daily living. Each item is rated from 0-10. Higher scores indicative greater interference.

    Measured: Baseline, prior to 11th treatment, after 10 weeks

Questions about this trial

What is this clinical trial studying?

A study testing StimaWell 120MTRS system in people with Low Back Pain and Paraspinal Muscles, run by Concordia University, Montreal at 1 site in Canada.

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 7 inclusion and 18 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 8 Mar 2024. 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 Canada. 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?

Change in multifidus muscle size (cross-sectional area) (time frame: Baseline, after 10 weeks). The study lists 5 primary outcomes in all. 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 NCT04891692, 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 8 Mar 2024.
