Advancing a Promising Treatment for Chronic Pain
Prolotherapy, an injection-based outpatient therapy practiced for over a century, offers the potential for effective, non-opioid management of pain due to osteoarthritis, overuse tendon disorders and back pain.
When performed by appropriately trained clinicians, prolotherapy can help decrease the impact of chronic musculoskeletal pain.
The UW Prolotherapy Education and Research Lab (UW PEARL), a collaboration between primary care and specialty clinicians based at the University of Wisconsin Department of Family Medicine and Community Health (DFMCH), furthers education and research on this promising treatment.
Why Focus on Prolotherapy?
- Chronic musculoskeletal pain has grown to epidemic levels.
- Existing therapies, including opioid medications, often do not address the root cause of chronic pain and may result in unwanted side effects.
- National organizations such as the Agency for Healthcare Research and Quality and the Institute of Medicine have called for new therapies for these conditions.
- Prolotherapy is understood to stimulate natural healing processes and is a promising modality at the intersection of conservative care and surgical intervention.
Evidence suggests that prolotherapy is effective for chronic musculoskeletal pain due to osteoarthritis, overuse tendon disorders and back problems—but more research is urgently needed.
What is UW PEARL?
UW PEARL is an interdisciplinary collaboration of clinicians conducting prolotherapy-related basic and clinical science, and providing education about prolotherapy. Founded by David Rabago, MD, in 2015, it is now directed by UW family physicians Michael Weber, MD and Jared Dubey, DO; Dr. Rabago continues in a consultant role.
Researchers associated with UW PEARL have conducted research on knee osteoarthritis, tennis elbow and other overuse tendon disorders. Through our education and research efforts, we hope to increase understanding of the appropriate use of prolotherapy.
- We work closely with the sibling organizations Hackett Hemwall Patterson Foundation (HHPF) and the International Association of Regenerative Therapy (IART), international leaders in the practice and teaching of clinical prolotherapy, and collaborate with both organizations in annual prolotherapy education and research conferences.
- We have published numerous scientific reports on the effectiveness of prolotherapy for osteoarthritis and tennis elbow.
- Members of UW PEARL have received federal, state and local funding to conduct this research; however, further efforts require additional support not available through granting organizations. Please consider a donation of any size.
