Pain Paid Clinical Trials in California

To demonstrate the potential benefits and risk of active sub-threshold stimulation in the treatment of chronic knee pain as compared to subjects that did not have active stimulation. Improvement will be assessed in relation to the clinical outcome measures of pain, with primary endpoint; Pain relief rate as measured by the number of subjects with greater or equal to a 50% decrease in pain on the visual analog scale, comparing baseline to the 1-month follow-up.

Proof of concept: Pilot Study A Pilot, proof of concept, observational study with a long-term goal to develop a minimally invasive wearable Remote Medication Monitor (RMM) that provides continuous, real-time data on methadone levels in interstitial fluid (ISF). An RMM could be used as a medication adherence monitor and would allow for the physician, counselor, patient, or family member to remotely verify that a physician-prescribed dose has been taken.

The purpose of this graduate student research study is to investigate the relationship between limited ankle dorsiflexion and the potential effects on a single limb squat task in the Patellofemoral/Knee Pain population. Read Less

The primary objective of this study is to prospectively determine, at 10 days after orthopedic shoulder or knee surgery, if pulsed electromagnetic field (PEMF) therapy is beneficial in reducing patient-reported post-operative pain, as measured by visual analog scale (VAS). The amount of pain medication taken daily and the physical function outcome scores after surgery and PEMF treatment will also be measured. Read Less

This trial is being completed to compare two commonly used options to treat pain after discharge from surgery. Participants that undergo tonsil removal, gallbladder removal, and knee scope will be eligible to enroll. Eligible participants will be randomized to prescription of 1 of 2 groups of medications (Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) plus acetaminophen or low dose opioids with the NSAIDs plus acetaminophen. The key question the study seeks to answer is which option will have the best outcomes and with the fewest side effects? Read Less

The purpose of this study is to characterize the pharmacokinetic (PK) and safety profile of anesthetics and analgesics in children and adolescents. Read Less

The investigators hypothesize that not prescribing opioids after uncomplicated, outpatient IHR will be non-inferior to prescribing opioids (5 tablets of Oxycodone, 5mg; or surgeon preference for intolerance) with respect to requests for opioid refills. Additionally, the investigators believe there will be no significant difference in postoperative readmission for pain quality of life at 30 days in either group. Read Less

The purpose of the chronic pain master protocol is to compare independent pain interventions and establish an overarching structure for the disease-state addenda (DSA) and intervention-specific appendices (ISAs). The ISAs may start independently of other ISAs as interventions become available for clinical testing. Read Less

The main objective of this study is to establish novel measures derived from Total-body-Positron Emission Tomography/Computed Tomography (TB-PET/CT) as quantitative biomarkers for the investigation of myofascial pain. The TB-PET/CT assessed measures are those reflective of myofascial tissue metabolism, perfusion, and fatty infiltration. Read Less

The goal of this clinical trial is to compare ketamine to a placebo when given as a single infusion during IV sedation in adults with chronic pain and depression. We do not know whether ketamine will be more effective than placebo under these circumstances. This study aims to: * Evaluate whether placebo is non-inferior to ketamine in treating chronic pain and depression, when delivered under propofol sedation * Confirm that propofol sedation is a safe way to keep participants blinded to treatment * Assess patients' comfort with the sedation process to improve future studies * Explore whether patient expectations affects their pain and depression Participants will: * Need to qualify for the study based on stringent medical criteria * Undergo sedation with propofol * Randomly receive either a ketamine or a placebo (saline) infusion during sedation * Complete several study assessments over 5-7 weeks Read Less

This is a non-surgical trial comparing the clinical and functional outcomes of patients with osteoarthritis treated with Intra-articular injection of Micro Fragmented Adipose Tissue versus conventional therapy of intra-articular injection of corticosteroid. Read Less

The quadratus lumborum (QL) block is a fascial plane block that has been described to provide analgesia from T7-L3 dermatomes. The investigators aim to evaluate the efficacy of QL blocks in patients undergoing primary total hip arthroplasty (THA). Read Less
