Mobile Technology to Measure Knee Health in Osteoarthritis

Osteoarthritis, Knee

Veterans face a high prevalence of knee osteoarthritis (OA), but current diagnostic methods often miss early stages when interventions are more effective. This project will evaluate smartphone-based motion capture via OpenCap to measure joint mechanics in knee OA patients during functional activities, comparing its performance to a conventional motion capture system, patient-reported symptoms, and knee joint structure. The findings will have the potential to enable clinicians to trial OpenCap in its current form, provide insights into tracking joint health, and guide refinements to advance toward earlier diagnosis of knee OA by complementing symptom assessments with measures of joint mechanics.

Adipose-Derived Biocellular Regenerative Therapy for Osteoarthritis

Osteoarthritis · Osteo Arthritis Knee · Osteo Arthritis Shoulders

Use of Biocellular and cellular approaches to treatment of Osteoarthritis (OA), musculoskeletal aging processes, pain, and degenerative changes are to be studied with minimally invasive protocols, and non-pharmaceutical means to relieve OA and its associated issues. Traditional surgical interventions have not yielded convincing long-term outcomes, including total joint replacement surgeries and medical management of the supportive structures. This study is to use a person's own stem/stromal Cells (autologous) plus HD-PRP (important healing growth factors and signal molecules) in such cases of OA for long-term minimally invasive treatments. Baseline (existing) findings are documented, and thence tracked as to progress deemed to be result of the intervention.

Brain Mechanisms Supporting Cannabis-induced Pain Relief

Sciatica · Lumbar Radiculopathy · Lower Back Pain

Chronic low back pain is a common and disabling condition that affects millions of people in the United States. Many people with chronic low back pain do not get enough relief from current treatments. Cannabis may help reduce pain, but researchers do not fully understand how it affects the brain in people with chronic pain. The purpose of this study is to examine how inhaled cannabis changes brain activity and reduces pain in people with chronic low back pain. Results from this study may help researchers better understand how cannabis works for pain and support the development of improved pain treatments.

A Randomized Pilot rTMS Trial for Knee Arthritis Pain and Depression

Knee Osteoarthritis · Depression

Osteoarthritis (OA) is a major public health problem, and involvement of the knee is especially disabling. Symptomatic knee OA has an incidence rate between 40 to 1,020 per 100,000 person years1 and is among the most common causes of disability worldwide. Knee arthritis pain and disability are highly comorbid wiht depression (30-50%). Currently available treatments offer only limited relief. The Pilot project aims to establish feasibility of the rTMS neuromodulation of response to Tai Chi and improvement in pain and comorbid depression in patients with knee OA. There are several ways in which the pilot project will improve scientific knowledge, and clinical practice: 1) The sequential stimulation of two targets (M1 and l-DLPFC) has not been systematically examined for the treatment of comorbid MDD and knee OA. We hypothesize that using a multi-target rTMS strategy combining M1 and l-DLPFC- active targets will be well tolerated and more effective to treat comorbid symptoms than single site rTMS to M1+l-DLPFCsham. This hypothesis will be tested in Aim 1 of this proposal by comparing two experimental conditions: A) M1active and l-DLPFCactive; and B) M1active and l-DLPFCsham. 2) Identifying the relationship between improvement in pain and depression to improvement in pro-inflammatory cytokines would be novel. Adding an rTMS as a neuromodulation technique with novel stimulation sites to assist in the reduction of symptoms of pain and depression is another scalable to clinical use opportunity that will provide pilot data for future clinical trials. We will perform a pilot feasibility trial of rTMS for those presenting with knee osteoarthritis related pain and moderate to severe depression in 30 volunteers who are undergoing Tai Chi intervention. Tolerability and safety of rTMS added to Tai Chi will be assessed along with changes in symptoms of pain and depression, in preparation to future R-01 applications.

FDG PET/MRI Imaging of Patellofemoral Joint Osteoarthritis

Patellofemoral Osteoarthritis · Knee Osteoarthritis · Knee Pain

This project aims to develop an \[18F\] fluorodeoxyglucose (FDG) positron emission tomography (PET) / magnetic resonance imaging (MRI) method to locate the painful inflammation in PFJ OA associated with joint loading. \[18F\] FDG PET/MRI is an emerging pain imaging approach with enhanced sensitivity to painful hypermetabolic inflammation through evaluation of intracellular glucose utilization rate via (\[18F\]FDG PET) and fine anatomy details (MRI). The investigative group has shown its promise in revealing previously unidentified or unspecified pain generators in various musculoskeletal pain conditions. The investigators have also demonstrated the feasibility of visualizing the structural changes between unloaded and loaded knee joints with MRI, which can be easily adopted in the current PET/MRI setting. The main challenge in the proposed \[18F\]FDG PET/MRI approach is to differentiate the normal uptake of FDG for metabolic changes by weight-bearing from abnormal changes indicating eventual pain aggravation by weight-bearing and knee-flexion. The investigators have garnered the following two aims to validate the proposed method by comparing unloaded and loaded knee imaging results between PFJ OA pain patients and asymptomatic, matched controls.

Phenotyping Response to Spinal Cord Stimulation in Chronic Low Back Pain

Chronic Low Back Pain

Chronic low back pain (CLBP) is a debilitating condition and costly to treat. Long-term drug treatment often fails due to habituation, breakthrough of pain, or adverse effects of drug treatment. Opioid use to manage this pain has contributed to the opioid epidemic. Spinal cord stimulators have emerged as a promising treatment and reduces reliance on drugs. However, response to spinal cord stimulation (SCS) is unpredictable. It is difficult to predict which patients will respond positively to SCS because the physiological mechanism for treatment responsiveness is unclear. Therefore, the aim of this study is to investigate how spinal cord stimulators affect functional measures in patients with CLBP, including functional MRI, neurophysiology, gait analysis, and questionnaires. The results of this study can lead to the widespread adoption of spinal cord stimulators as a safe and effective therapy for CLBP, reducing the reliance on opioids and mitigating the opioid epidemic's impact.
