About this study

Official title: Prospective, Randomized, Double-Blind, Placebo Controlled Study to Evaluate the Safety and Efficacy of Pulsed Electromagnetic Field (PEMF) Therapy as an Adjunctive Treatment to Surgical Repair of Full Thickness Rotator Cuff Tears

The primary objective of this study is to prospectively determine, at 12 months post-surgical repair of full thickness rotator cuff tears, the safety and efficacy of treating full thickness rotator cuff repairs with pulsed electromagnetic fields (PEMF). The hypothesis states that exposure to a pulsed electromagnetic field (PEMF) following surgical repair of a full thickness rotator cuff tendon tear reduces tendon re-tear rates. The strength of the shoulder muscles and the levels of pain in subjects after surgical repair of their rotator cuff adjunctively treated with an active PEMF device will also be measured.

Read the detailed description

This Clinical Investigation Plan (CIP) describes the prospective, randomized, double-blind, placebo controlled study to evaluate the safety and efficacy of Pulsed Electromagnetic Field (PEMF) therapy as an adjunctive treatment to surgical repair of full thickness rotator cuff tears.

Rotator cuff tears are common musculoskeletal injuries which often require surgical intervention. Unfortunately, post-repair prognosis is poor, and surgical repairs have been reported to fail in up to 94% of cases (Galatz et. al., 2004). Repaired tissue tends to be fibrotic, disorganized, and reattaches poorly to the bony insertion. To improve tendon-to-bone healing, many non-invasive therapeutic devices have been utilized post-operatively including therapeutic ultrasound and shock wave therapy (Lovric et. al., 2013; Springer and Badgett, 2015).

In orthopedics, the use of these non-invasive therapeutic devices has become increasingly popular during the post-operative recovery period in an effort to enhance tissue healing. These devices are relatively inexpensive and easily obtainable and relatively easy to use, and are especially enticing as they can be brought into the patient's home and do not require frequent visits to the clinic. Additionally, non-invasive therapeutic devices can be used for a variety of applications, including promoting tissue healing prior to surgical intervention or in lieu of surgical intervention all together. Although there are numerous advantages to using non-invasive therapeutic devices, their efficacy has not yet been maximized.

Based on the pre-clinical work presented (Tucker et. al., 2016; Huegel et. al., 2017), it is believed that pulsed electromagnetic fields may be an effective adjunctive treatment for patients who have undergone surgical repair of a torn rotator cuff.

What is being measured

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

  1. retear rate

    A reduction in retear rates in subjects adjunctively treated with PEMF compared with those treated with a placebo (inactive) RCStim PEMF device following surgical repair of full thickness rotator cuff tears.

    Measured: 12 months

Secondary outcomes (2)
  1. Muscle Strength

    Strength to be measured using the IsoForceEvo2 dynamometer in subjects treated with PEMF treated and compared with subjects receiving the placebo/control PEMF device

    Measured: 12 months

  2. Penn Shoulder Score

    100 point scale with three subscales (pain, satisfaction, function) where a 12 pt increase in score with time after PEMF treatment is minimally clinically significant

    Measured: 12 months

Timeline

  2. Study start15 Jan 2018
  3. Primary completion31 Dec 2022

Why it stopped: Interim results suggested that the study was not adequately powered to achieve the primary endpoint: superiority in retear rate reduction in PEMF treatment versus placebo.

Questions about this trial

What is this clinical trial studying?

A study testing RCStim Model 1114 in people with Full-thickness Rotator Cuff Tear, run by Orthofix Inc. at 23 sites 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 15 inclusion and 38 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: stopped early, as of the sponsor's last update on 30 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 23 sites 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. 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 was stopped early (reason given: Interim results suggested that the study was not adequately powered to achieve the primary endpoint: superiority in retear rate reduction in PEMF treatment versus placebo.). Results are not available in the source record.

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?

retear rate (time frame: 12 months). 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 Aug 2023.
