Arthritis clinical trials at University of California Health

More than two million Americans are currently living with a full or partial limb loss, and an additional 185,000 amputations occur each year. The majority of amputations occur in the lower limbs. There are many potential causes for amputation, but the majority can be attributed to vascular diseases, such as diabetes, traumatic injury, and cancer. For these individuals, prosthetic devices play an important role in restoring mobility and enabling them to participate in everyday activities. However, when learning to use these devices, patients often alter their movement patterns to compensate for pain or discomfort, a decreased ability to feel what their prosthetic limb is doing, and/or a fear of falling. By changing their movement patterns, patients will tend to am their intact leg, which has been shown to lead to long-term joint damage and chronic injury. For perspective, 75% of United States veterans living with amputation are diagnosed with a subsequent disease affecting their muscle, bone, and/or joint health. Therefore, therapy sessions, known as gait retraining, are an integral part of teaching prosthesis users to walk in a safe and efficient manner. With recent advances in wearable technology, researchers and therapists have begun exploring the use of biofeedback systems to assist with this retraining. In these systems, wearable sensors are used to measure how the patient is moving in real-time, and can provide information on how much time they spend on each leg and how much each joint moves during walking. Biofeedback refers to the process of communicating the information from these sensors back to the patients instruct them whether they need to change their movements. Previous research has shown that these systems have excellent potential for helping patients with physical disabilities improve their quality of motion. However, relatively little research has explored how well individuals with above-knee leg amputations respond to biofeedback during gait retraining. Importantly, the question of whether the new movement patterns taught using biofeedback will persist after training has finished remains unanswered. Therefore, the primary objective of this research is to determine whether biofeedback is a feasible tool for gait retraining with above-knee prosthesis (including a prosthetic knee, ankle, and foot) users. To answer these questions, forty individuals currently using above-knee prosthetic systems will undergo a single session of biofeedback training. Half of these populations will be from the civilian population, and half will be military veterans. During this training, the biofeedback system will apply short vibrations - similar to those generated by cellphones - to their skin every time that the patient reaches the desired degree of hip rotation during walking. Participants will be instructed to keep increasing their hip motion until they feel a vibration on every step. Before training, they will be instrumented with a wearable motion captures system, pressure sensors embedded in their shoes, and a wearable heart rate monitor. Using these devices, researchers will measure the participants' walking patterns without biofeedback determine their current ability. Once training is complete, their walking patterns will be measured again, first while using the biofeedback system, and then again fifteen minutes and thirty minutes after the biofeedback system has been removed. The data measured during these tests will enable researchers to calculate functional mobility scores that are used to evaluate the quality of a patient's walking, and then compare how these scores change before, during, and after biofeedback training. The knowledge gained through this research constitutes a critical step towards identifying optimal biofeedback strategies for maximizing patient mobility outcomes. The findings will be essential for the development of gait retraining protocols designed to reduce the incidence of chronic injury, and enable patients to achieve their full mobility potential. Building on these results, the next research phase will be to incorporate biofeedback training into a standard six-week gait retraining protocol to evaluate its long-term effectiveness as a rehabilitation tool. Unlike traditional gait retraining, which requires patients to visit clinics in-person for all sessions, the wearable, automated nature of biofeedback training will allow patients to continue gait training from home. This ability will enable patients to continue training activities between sessions, and ultimately may be able to substitute for some in-person visits. This potential for remote therapy has exciting implications for improved access to care for individuals living long distances from their rehabilitation providers, or those suffering from social anxiety, as well as during global health pandemics where in-person visits are difficult.

This clinical trial will test a mindfulness program in individuals with rheumatoid arthritis (RA). The main goals of this pilot study are to: - Assess patient satisfaction with a mindfulness course - Identify barriers to participation in, or completion of, a mindfulness course - Gather initial information to understand how a mindfulness course impacts RA symptoms Participants will: - Complete online questionnaires - Attend two in-person study visits, involving a brief joint exam and blood draw - Roughly half the participants will have the chance to participate in an 8-week online mindfulness course - Roughly half the participants will be invited to participate in an online focus group following completion of the mindfulness course Researchers will compare those in the mindfulness course with those receiving standard care in preparation for a larger future study to see how mindfulness impacts stress and inflammation in individuals with RA.

Shared decision making is the first overarching principle for the treat to target guidelines for rheumatoid arthritis (RA) and has been proposed as a potential mechanism to reduce health disparities, however there is little evidence to inform effective ways to implement this practice in the care of Veterans with RA. The purpose of this project is to evaluate the effectiveness of a multi-component shared decision making intervention on RA disease activity, adherence to RA medications and patient knowledge of RA. The proposed research will contribute to fundamental knowledge about how to effectively foster shared decision making across varied VA rheumatology clinical settings to improve patient disease outcomes and experience; and support clinicians to engage patients in meaningful ways with the ultimate goal to improve health, reduce disability, and eliminate disparities.

This study will test the safety and effects of SBT777101 when given as a single dose to subjects with rheumatoid arthritis. It is the first study of this treatment being done in humans. Increasing dose levels will be given after the safety at lower dose levels is shown.

A study to identify patients with Rheumatoid Arthritis - Associated Interstitial Lung Disease (RA-ILD) that are at the highest risk for progression. The goal of the investigators is to recruit a group of patients with RA-ILD and collect information to help us understand more about disease progression. The investigators will do this using a combination of clinical, radiologic, and biologic features.

The goal of the Shoulder iD™ Primary Reversed Glenoid Outcomes Clinical Study is to collect safety and performance data on the commercially available Shoulder iD™ Primary Reversed Glenoid device. The study will learn about standard device use in adult patients who have a functional deltoid muscle and massive and non-repairable rotator cuff tear. The main questions it aims to answer are: - What is the average improvement in patient-reported shoulder function after 2 years when compared to before the surgery, and - What is the rate of surgical revisions needed over a 10 year period Patients will be asked to will be asked to regularly attend their check-up visits with their surgeon (including having x-rays or CT images taken to check their shoulder and implant), to complete questionnaires to report how their shoulder is doing, and to tell their surgeon when they notice any changes.
