Brief summary
This study seeks to identify patient reported and clinically measured outcomes for pain management and elbow function with application of semiconductor embedded fabric combined with PRP+ASC injections in the affected area.
Detailed description
Extensor Carpi Radialis Brevis (ECRB) tendinopathy, also known as lateral epicondylitis or tennis elbow, is the most prevalent elbow soft tissue injury and affects 1-3% of the population. Repetitive overloading of the tendon and ligaments in the elbow lead to microtraumas, causing abnormal angiofibroblastic remodeling and increased pain. Microtearing occurs most commonly at the origin of the extensor carpi radialis brevis (ECRB) tendon. The main symptoms include a loss of grip strength, a burning sensation near the ECRB origin site, and pain during daily activities such as grasping objects or shaking hands. Both conditions present a significant injury and treatment burden on the population and effective treatment and pain management approaches with minimal side effects are needed. Novel nonsurgical treatment approaches for ECRB tendinopathy include platelet-rich plasma (PRP) injections and stem cell therapy. Ultrasound-guided PRP and adipose-derived stem cells (ASCs) injections have shown to be an effective treatment option for patients with chronic ECRB tendinopathy. The proposed study seeks to assess the effect of non-compressive semiconductor embedded arm sleeves in combination with PRP + ASC injections, throughout a 6-month rehabilitation course for patients with ECRB tendinopathy. Outcome measures will be collected at standardized intervals to evaluate and compare treatment groups.

Intervention model description
Subjects will determine whether they would like to receive Standard of Care (SOC) PRP+ASC injections. Then, the subjects will be randomly assigned to the study group in which they will receive a real or sham semiconductor embedded sleeve. The subjects will be instructed to wear the sleeve for a minimum of 12 hours per day, including overnight, for the entire duration of the study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in patient elbow function and pain as determined by the Patient-Rated Tennis Elbow Evaluation (PRTEE). | 6 months | The Patient-Rated Tennis Elbow Evaluation (PRTEE) is a self-administered questionnaire that assesses elbow pain and functional ability in patients with tennis elbow. The minimum number is zero meaning no pain and the maximum number is 10 meaning the worst imaginable pain. Lower scores are ideal while higher scores are indicative of the patient in a lot of pain and minimal functional ability |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in pain as determined by the Visual Analog Scale (VAS). | 6 months | The pain VAS is a unidimensional measure of pain intensity, used to record patients' pain progression, or compare pain severity between patients with similar conditions. The minimum number is zero meaning no pain and maximum number is 10 meaning the most pain the patient has every felt in their entire life. Lower scores are ideal while higher scores are indicative of the patient in a lot of pain. |
| Change in patient elbow function as determined by the Disabilities of the Arm, Shoulder, and Hand (DASH). | 6 months | The Disabilities of the Arm, Shoulder, and Hand (DASH) is a self-administered questionnaire that assesses the patient's functional ability and arm, shoulder, or hand pain. It is on a 5-point likert scale with 1= No difficulty, 2 = Mild difficulty, 3 = Moderate difficulty, 4 = Severe difficulty, and 5 = Unable. The score ranges from 0 to 100, with higher scores indicating greater disability. |
| Change in grip strength as measured by a hand dynamometer | 6 months | Patient's grip strength will be assessed with a hand dynamometer. The patient will squeeze the device with the patient's elbow at 90 degrees of flexion and wrist in 30 degrees of extension. A force output value in pounds (lbs) will be displayed and a higher number of force output indicates a stronger grip strength. |
