Transcutaneous Spinal Cord Stimulation for Chronic Low Back Pain
Recruiting
As a leading cause of disability worldwide, chronic low back pain (cLBP) represents a significant medical and socioeconomic problem with estimated health care spending of $87 billion/annually. The efficacy of dorsal column electrical stimulation to inhibit pain was first described over 50 years ago. Since then, several large clinical trials have investigated the therapeutic potential of electrical spinal cord stimulation (SCS) and found that over 70% of patients with intractable pain had over 50...

Comparative Effectiveness of MRgFUS Versus CTgRFA for Osteoid Osteomas
Recruiting
Osteoid osteomas are painful, benign bone tumors that occur most frequently in young males between ages 10 and 20 years. The goal of the proposed study is based on the premise that MRgFUS is noninferior to CT-guided radiofrequency ablation (CTgRFA), in terms of pain reduction following treatment of osteoid osteomas, and offers possible improvements with regards to 1) post-procedural pain, 2) clinical resource utilization, 3) patient experience, and/or 4) adverse events. The data from the current... Read More

Kaiser Permanente houses over 6,000 physicians in southern California and it is also one of the largest research centers on the state. On its clinical trial division, Kaiser Permanente conducts clinical trials of almost every specialty funded by pharmaceutical companies, government, and foundations.
The Cedars-Sinai Medical Center located in Los Angeles is one of the largest research centers owned and operated by a private hospital in the United States. Focusing on biomedical, cancer, and heart research among other specialties, you can find almost any type of clinical trials for both health and non-healthy volunteers at the research division of Cedar-Sinai Medical Center.
There are around 100,000 clinical trials happening every year across the United States about almost every condition out there. While most clinical trials are testing drugs or medical devices there are also many behavioral and observational trials going on at any point in time. Many paid research studies are held at these California locations.
Clinical trials are incredibly important for making new medical and scientific discoveries, finding new and better methods for diagnosing medical conditions early, testing new interventions, and even developing safer and more effective surgical procedures.
In order for all these discoveries to me made available to the general population they need to go through years of rigorous testing both in healthy and non-healthy volunteers. During those years, medical professionals follow a protocol that has been previously approved by the FDA or other regulatory agency to test the effectiveness and safety of their discovery.
Other people choose to participate in a clinical trial because they feel it is a good way to contribute to the advancement of medical knowledge and that their participation can help many people in the future.
