Clinical Research


IPM physicians consider research an extension of treating the patient.  Research continually reveals new ways to manage pain.  Our doctors have studied various therapies for pain management, and participated in research studies exploring the use of new devices for spinal cord stimulation to alleviate pain.  This sets us apart in the field of pain management; few practices in the United States are doing investigational device studies.

We are also pleased to share several of our doctors have worked in spine research using stem cells, a therapy showing promise in treating spinal diseases and symptoms of pain. Recognized around the globe as thought leaders in the field of pain management, IPM physicians are heavily invested in teaching a new generation of pain management student doctors, consulting for therapeutic companies and act as keynote speakers and presenters at industry conferences and lecture series.

Research is key to our doctors staying ahead of medical advancements.  Check back often for an updated list of active and upcoming studies.


Active IPM Studies (Currently Enrolling)

Nature Cell JointStem Study for Moderate Osteoarthritis of the Knee 

This study is for patients that have been previously diagnosed with moderate osteoarthritis in the knee. In this study, we will be evaluating the efficacy and safety of using stem cells from your own fat tissue for the treatment of osteoarthritis in the knee.

Mesoblast CASCADE DR003 Stem Cell Study 

This study is primarily indicated for patients with chronic discogenic lumbar back pain (> 6 months) associated with moderate Degenerative Disc Disease (DDD).  For more information, click on the following link below:

Past IPM Studies (Enrollment Closed)

Nevro Upper Limb and Neck Pain Study 

IPM Medical Group is one of seven sites in the United States participating in the Nevro ULN study. We are looking to study the effectiveness and safety of the Senza System in patients with chronic, intractable pain of the upper limbs and/or neck.
