Pain Paid Clinical Trials in California

This is a single-center pilot study to determine if an adductor canal continuous nerve block is superior to single injection nerve block following total knee arthroplasty. Investigators will randomize participants to either continuous nerve block or single injection nerve block for the adductor canal preoperatively. They will assess differences in pain (measured in numeric rating scale), opioid consumption, and physical therapy milestones from postoperative day 0 to 7. Read Less

Chronic neuropathic pain is defined as pain caused by a lesion or disease of the somatosensory nervous system. It is highly prevalent, debilitating, and challenging to treat. Current available treatments have low efficacy, high side effect burden, and are prone to misuse and dependence. Emerging evidence suggests that the transition from acute to chronic neuropathic pain is associated with reorganization of central brain circuits involved in pain processing. Repetitive transcranial magnetic stimulation (rTMS) is a promising alternative treatment that uses focused magnetic pulses to non-invasively modulate brain activity, a strategy that can potentially circumvent the adverse effects of available treatments for pain. RTMS is FDA-approved for the treatment of major depressive disorder, obsessive-compulsive disorder, and migraine, and has been shown to reduce pain scores when applied to the contralateral motor cortex (M1). However, available studies of rTMS for chronic neuropathic pain typically show variable and often short-lived benefits, and many aspects of optimal treatment remain unknown, including ideal rTMS stimulation parameters, duration of treatment, and relationship to the underlying pain etiology. Here the investigators propose to evaluate the efficacy of high frequency rTMS to M1, the region with most evidence of benefit in chronic neuropathic pain, and to use functional magnetic resonance imaging (fMRI) to identify alternative rTMS targets for participants that do not respond to stimulation at M1. The central aim is to evaluate the pain relieving efficacy of multi-session high-frequency M1 TMS for pain. In secondary exploratory analyses, the investigator propose to investigate patient characteristic that are predictive of responsive to M1 rTMS and identify viable alternative stimulation targets in non-responders to M1 rTMS.

The goal of this research study is to learn more about how different uses of a numbing medication might affect pain levels while getting an IUD placed. The investigators are also studying participants opinions of their clinicians' empathy. The investigators are inviting patients who arrive at their clinic visit seeking an IUD. Usually, at University of California, San Diego (UCSD), for patients who have never delivered a baby, clinicians use a buffered paracervical block for before IUD placement. The purpose of this research study is to investigate whether a "buffered" (2 cc of sodium bicarbonate, 18 cc of 1% lidocaine) paracervical block (numbing medication given on both sides of the cervix) is effective in reducing pain during IUD placement in individuals with prior C-sections, the difference between buffered and unbuffered for nulliparous patients, and whether a medicated gel reduces pain with the paracervical block.

The purpose of this study is to evaluate the clinical utility of neurophysiological measurements of ECAP-controlled closed-loop SCS (i.e., neural panel metrics) to guide treatment of chronic pain of the trunk and/or limbs. Read Less

This study is looking into how safe and useful NOCISCAN is. NOCISCAN is a software as a Service (SaaS) tool that uses Magnetic Resonance (MR) spectroscopy. Nociscan (instead of 'It') leverages MRS to noninvasively help physicians distinguish between painful and nonpainful discs in the lumbar spine. The randomized controlled trial will compare the blinded and unblinded cohorts and their corresponding surgical outcomes with the Nocigram reports, generated prior to treatment, for each patient."

Patients with angina and non-obstructive CAD are common within clinical practice, but remain a challenge with regard to diagnosis and treatment. When these patients undergo a comprehensive evaluation at the time of invasive coronary angiography, occult coronary abnormalities are frequently found. We hope to learn the overall prevalence and presentation of these occult coronary abnormalities and its long term outcome in this patient population. Read Less
