Dr. Eric Y. Chang is an interventional physiatrist subspecializing in wellness and the treatment of pain. He offers a variety of treatments for neuropathic and musculoskeletal pain conditions. He treats non-operative neck and low back pain, spasticity, myofascial pain, scoliosis/kyphosis, compression fractures, sciatica and neuropathic pain conditions.

Chang performs a multitude of interventional procedures in the neck and low back, as well as advanced procedures such as spinal cord stimulators and intrathecal drug delivery pumps. He is experienced in the use of regenerative therapies (plasma rich platelets, stem cells therapy) to treat osteoarthritis and chronic injuries. He is also trained in electromyography. His special clinical and research interests are neuropathic pain, spasticity, arthritis and spinal disorders.

Chang’s basic science research interests are in investigating the pain mechanisms of low back pain and sciatica.  Low back pain is a major cause of morbidity and mortality in the world. A common cause of back pain is from degenerative disc disease, which may present with radicular pain. Currently, low back pain secondary to degenerative disc disease is not well characterized and imaging studies do not correlate with the extent of pathology. In addition, little is known about the mechanisms associated with the actual progression of degenerative disc disease and radicular pain. As a result, these patients have limited diagnosis and treatment options for their pain and disability.

Message from Dr. Mora

I hope to create a close patient-doctor relationship based on trust and mutual respect. I believe my patients’ medical treatment begins with their complete understanding of their condition, and I promise to do my very best to understand the cause of your pain and then provide a treatment approach that is tailored to meet your specific needs.

I believe that my success in diagnosing and treating orthopedic problems was borne out of my own personal traumatic injury to my legs. While living in Peru, I was struck by a commuter bus, severely injuring my legs and forever changing my life. I have experienced many of the same surgeries that I now perform on my own patients — and I believe this experience has allowed me to be more in tune with my patients’ concerns, symptoms and experiences.


My family heritage is Peruvian and I speak fluent Spanish.

Treatment of each person and condition needs to be tailored specifically to that individual patient.
