Stem Cell Research:

  • As a national center for research, Dr Paicius has been involved in studies for abdominal pain, for headache, for failed back surgery as well as the innovative area of regenerative medicine. Recently Dr. Paicius completed a study for back pain with introduction of stem cells into the intervertebral disc with amazing success.

  • As we continue to be a national center for research, newer treatments for pain become available on a monthly basis. Below are some of the studies Dr Paicius has been involved in for the last several years.

Research Cases:

A Prospective Clinical Trial to Assess the Feasibility of the SENZA Spinal Cord Stimulation (SCS) System in the Treatment of Chronic Abdominal Pain

Purpose: The purpose of this study is to find out whether electrical stimulation of the spinal cord using SENZA is safe and useful in the treatment of chronic (long-term) pain of the abdomen.


Enrollment Status: Not enrolling, active patients.

A Prospective, Multicenter, Randomized, Double-blind, Placebo-controlled Study to Evaluate the Efficacy and Safety of a Single Injection of Rexlemestrocel-L Alone or Combined with Hyaluronic Acid (HA) in Subjects with Chronic Low Back Pain

Purpose: The purpose of this research study is to evaluate an investigational product called, rexlemestrocel-L. This study is designed to determine whether rexlemestrocel-L, used alone, or in combination with a carrier material (hyaluronic acid), is safe and effective in treating low back pain by repairing damaged spinal discs.


Enrollment Status: Not enrolling, active patients.

A Post Market Registry for Evaluation of the Superion Spacer

Purpose: This registry is being conducted to collect additional data about the performance of the Superion Indirect Decompression System which is manufactured by Vertiflex. The device was approved by the FDA for sale in the U.S. in May 20, 2015.
