About this study

Official title: Blood Flow Restriction Training Following Acute Shoulder Injury In Baseball Players: Assessment of Efficacy in Return to Sport

The literature is limited on whether BFR therapy provides improved return to function after acute rotator cuff or biceps rehabilitation in non-operative cases, and whether there is a clear mechanism of action in musculotendinous repair after BFR therapy. The purpose of the study is to 1) evaluate patient reported outcomes and return to play in baseball athletes undergoing rehabilitation with blood flow restriction (BFR) therapy for shoulder injury and 2) evaluate changes in blood biomarkers to assess the mechanism of action of BFR therapy in injured athletes. Investigators will perform a randomized blinded placebo-controlled trial of 2 separate study populations: 1) baseball players with biceps or rotator cuff tendinopathy undergoing non-operative treatment with BFR therapy incorporated into routine physical rehabilitation and 2) baseball players with biceps or rotator cuff tendinopathy undergoing non-operative treatment with routine physical rehabilitation alone.

Primary outcomes will be functional outcomes and evaluation of return to sport. Functional outcomes will be evaluated using validated patient reported outcome surveys that are upper extremity-specific. Return to sport will be assessed by evaluating time to receiving clearance for returning to routine practices and reported level of physical performance and re-injury. Secondary outcomes will be measurement in muscle strength and blood biomarkers, as well as evaluation of 3D throwing motion. Strength will be measured using a biodex system at baseline prior to beginning physical rehabilitation, half-way through the rehabilitation protocol +/- BFR phase, and once cleared for return to play. Blood biomarkers GH, IGF-I, and IL-6 will be quantified at the same time points in order to investigate the mechanism of action of BFR on tissue repair. Patients will be followed longitudinally during this time for rates of reinjury.

Read the detailed description

This study will evaluate the efficacy of BFR therapy in physical rehabilitation for baseball athletes with non-operative biceps or rotator cuff tendinopathy. This will be directly measured by evaluation of upper extremity biomechanics measurements, strength testing, patient reported functional outcome scores, and identifying time required for clearance of return to sport. These outcomes in patients undergoing BFR therapy in addition to traditional rehabilitation will be compared to patients undergoing traditional rehabilitation only.

What participants receive

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

  • Blood Flow Restriction TherapyDevice

    The blood flow restriction cuff, which is regulated by the FDA under 878.5910 and is registered under number 9681444, is manufactured by Delfi Medical. The cuff will be used as recommended by the manufacturer and Owens Recovery Science, the company who provides certificating of blood flow restriction training.

  • Standard physical rehabilitationOther

    Patients diagnosed with non-operative rotator cuff or biceps tendinopathy will undergo physical rehabilitation under the supervision of the same physical therapists who will be performing the BFR therapy.

Questions about this trial

What is this clinical trial studying?

A study testing Blood Flow Restriction Therapy and Standard physical rehabilitation in people with Musculoskeletal Injury, run by Wake Forest University Health Sciences.

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 2 inclusion and 5 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: withdrawn, as of the sponsor's last update on 16 May 2022. Status can change between updates, so confirm with the study contact before making plans.

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 was withdrawn before enrolling participants, so there are no results.

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?

American Shoulder and Elbow Surgeons (ASES) questionnaire (time frame: Questionnaire assigned at baseline prior to the rehabilitation protocol.). The study lists 12 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 NCT04248413, which also lists 63 linked publications.

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 16 May 2022.
