About this study

Official title: Functional and Electromyographical Changes After Platelet Rich Plasma or Dextrose Injection in Chronic Lateral Epicondylitis

The purpose of this study is to find out functional and electromyographical changes after platelet rich plasma and dextrose injection in chronic lateral epicondylitis.

Read the detailed description

Both platelet rich plasma (PRP) and dextrose treat chronic lateral epicondylalgia (CLE), mechanically by enhancing tendon cell proliferation, differentiation, and maturation. In fact, hypertonic glucose injection is much cost-effective as compared to PRP. Hence, it is of clinical value to compare the recovery of extensor carpi radialis breveis (ECRB) muscular structure and muscular function between PRP and hypertonic glucose injection.

The investigators will measure functional outcome and force gradation after PRP and glucose injection in CLE patients using multi-electromyography, functional score (Disabilities of the Arm, Shoulder and Hand (DASH) and Patient-Rated Tennis Elbow Evaluation (PRTEE)) and force (gripping power and maximal voluntary contraction (MVC) during wrist extension) before and 12 weeks after injection. The hypotheses of this study are 1) lower MVC and greater force fluctuations of a force task in the affected muscle in individuals with CLE; 2) lower discharge rate and higher discharge variability of motor units of a force task in the affected muscle in individuals with CLE than those in the contralateral sound side; 3) the PRP group shows a greater improvement in a visual analog scale (VAS), DASH, PRTEE score, MVC, and the size of force fluctuations than the glucose group after treatment. 4) the PRP group shows a greater discharge rate and lower discharge variability for a force task than the glucose group after treatment.

What participants receive

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

  • Platelet Rich PlasmaDrug

    Preparing 2 mL of PRP with concentration of 4-6 times the average normal values, 20mL of blood will be first collected from the patient's upper limb cubital vein using an 18G needle. A local subcutaneous anesthesia (2 ml of 1% lidocaine) will be finished by the orthopedist.

  • Dextrose 50%Drug

    The group will use 4 ml of PRP + 4 ml of 0.9% saline -h 2 ml of 1% lidocaine (10-ml syringe).

What is being measured

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

  1. Pain score on a visual analog scale (VAS)

    a 10 cm line with anchor statements on the left (no pain) and on the right (extreme pain)

    Measured: 12 weeks

  2. Disabilities of the Arm, Shoulder and Hand (DASH) score

    scored 0 (no disability) to 100

    Measured: 12 weeks

  3. Patient-Rated Tennis Elbow Evaluation (PRTEE) score

    pain and disability from 0 to 10(0 = no difficulty, 10 = unable to do)

    Measured: 12 weeks

  4. Level of force

    extension of maximal voluntary contraction

    Measured: 12 weeks

  5. Level of force

    gripping power

    Measured: 12 weeks

  6. The gradation of muscle force(the surface electromyogram)

    the number of motor units active

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Platelet Rich Plasma and Dextrose 50% in people with Tennis Elbow, run by Chen Yueh at 1 site in Taiwan.

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 12 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: status not confirmed, as of the sponsor's last update on 14 Apr 2022. 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 Taiwan. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Yueh Chen (+886 921569617, b1729kimo@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain score on a visual analog scale (VAS) (time frame: 12 weeks). The study lists 6 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 14 Apr 2022.
