Pain Paid Clinical Trials in Tennessee

This is a prospective randomized controlled trial that will assess preoperative, perioperative, and long-term oxidative stress (OS); pain; and functional outcomes over a 12 month period and test the hypothesis that a potent antioxidant intervention (glycine + N-acetyl-cysteine(GlyNAC)) reduces oxidative stress and chronic post surgical pain (CPSP) in patients undergoing total knee arthroplasty (TKA).

Embo Registry is a retrospective and prospective observational study to evaluate real world effectiveness and the use of Artery Embolization as a treatment for chronic pain with patients that have osteoarthritis and localized pain to provide symptomatic relief. This study is to determine the efficacy and validity of procedure and that following procedure patients had decreased pain and improved quality of life. Read Less

The purpose of this study is to see how stress influences the effects of opioid pain medications often used to help relieve back pain. The study will help to learn more about how high stress levels could increase risk for pain medication misuse. Read Less

The purpose of this study is to compare opioid prescribing practices by either routine provider prescribing practices, or with the use of a calculator, i.e., the Opioid Calculator, published by the University of Michigan (www.opioidcalculator.org), with the intent of decreasing the number of pills.

Low back pain is a leading cause of disability worldwide. The lumbar zygapophyseal joints (z-joints) are estimated to be the source of low back pain between 10% and 40% of the time. Observational studies have shown that lumbar medial branch radiofrequency neurotomy (LMBRFN) can be an effective treatment for z-joint low back pain. Nonetheless, other publications such as the Cochrane collaboration systematic review and the "Minimal Interventional Treatments for Participants with Chronic Low Back Pain" or "MINT" randomized controlled trial conclude that LMBRFN is not efficacious. These discrepancies in the literature may be due to differences in patient selection and procedural technique. This study aims to employ patient selection via dual medial branch block resulting in at least 80% relief on both occasions. Using this rather strict enrollment criteria, the aim of the study is to then compare LMBRFN utilizing 16 gauge needles via the "parallel" approach as endorsed by Spine Intervention Society guidelines to LMBRFN performed with 22 gauge needles and another commonly employed "perpendicular" technique similar to that approach used for medial branch blocks. The primary outcome of the study will be to determine if there is a difference in the percentage of patients with lumbar facet pain who achieve moderate or good response (improvement of Numeric Pain Rating Scale of at least 50% or 80%) or in the duration of effect (median duration of moderate or good response in those with positive outcome) between these two groups.
