Not enough patients to enroll at the site

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.

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.

Inclusion Criteria:

1. Patients diagnosed with ECRB tendinopathy as determined by radiographic assessment or ultrasound imaging.
2. Patients age 18-65
3. Patients who are willing and able to adhere to follow-up schedule and protocol guidelines.
4. Patients who are willing and able to sign corresponding research subject consent form.

Exclusion Criteria:

1. Patient has a history of neurological conditions, including multiple sclerosis or Parkinson's disease
2. Patient has severe medical condition, including recent myocardial infarction, unstable angina, heart failure, severe anemia
3. Patient has had prior surgical treatment of the elbow in the last 5 years or injection treatment(s) in the last 2 years
4. Patient has complete tear of ECRB tendon or other surgical indication
5. Patient has chronic pain conditions unrelated to elbow condition
6. Patient has auto-immune or auto-inflammatory diseases
7. Patient has used tobacco within the last 90 days
8. Patient is not within the ages of 18-65
9. Patient has a history of metabolic disorders
10. Patient has an active infection (local or systemic)
11. Patient is unwilling or unable to sign the corresponding research subject consent form
12. Patient meets any other criteria or has any other condition that, in the opinion of the investigator, would prevent them from completing the study or that, in the opinion of the investigator, would confound study results.

Data will be stored and used for the duration of time required to conduct analysis and publish all proposed peer-reviewed papers, according to study objectives. Data will be retained for 2 years after publication to allow for re-analysis that may be initiated in response to readers/reviewers. Subject records will be maintained at the PI's clinical site for a minimum of 7 years following latest study follow-up.
