Funded Projects

Pain in the muscles and surrounding connective tissue (myofascial pain) is a significant health concern affecting hundreds of millions of Americans. Understanding and managing myofascial pain has been limited due to a lack of tools to help clinicians diagnose and treat this disorder. While past efforts to understand myofascial pain have focused on impairments in how connective tissues connect to other tissues in the body, this project will use a new imaging technique to study myofascial tissue physical properties, including how they move in the body and their structural stiffness. This research will identify an imaging biomarker to be used in a randomized controlled clinical trial to predict patient responses to a myofascial pain treatment.

Clinician bias causes inequities in healthcare, and interventions are needed to mitigate and eradicate this bias. This project aims to develop and test the impact of two interventions on overcoming clinician implicit bias in the management of pain for children from ethnic minorities treated in the emergency department. The study will include pediatric patients from under-represented minority groups with pain from long-bone fractures or acute appendicitis who are cared for by racially and ethnically diverse caregivers. Researchers will use stakeholder-informed approaches to establish quality of care metrics and then use clinician audit and feedback as well as data from electronic health records to quantify evidence of bias.      

Shoulder pain occurs in many patients who are recovering from a stroke. In addition to impairments in the ability to move, persistent shoulder pain contributes to depression, and often reduces quality of life. Although the cause of post-stroke shoulder pain is complex and not completely understood, it is thought to arise in part to damage of muscles and surrounding connective tissues (myofascial tissues) in the shoulder. This project will use advanced medical imaging techniques to create biomarkers of that can reliably identify myofascial tissues. The research will then test the ability of these biomarkers to monitor, and ultimately predict treatment responses in patients with post-stroke shoulder pain in the context of a randomized controlled clinical trial.

This project will identify molecular characteristics of human sensory neurons and non-neuronal cells from the human dorsal root ganglia. This structure located outside the spinal cord is integrally involved in communicating pain signals to and from the brain. The research will use molecular approaches to characterize tissues obtained from organ donors and in patients who experience chronic pain. The findings will also help generate a connectivity map, or “connectome,” of nerve cell connections between the dorsal root ganglia of the spinal cord and the brain.

There is a need to improve access to treatments and address the stigma, bias, and mistrust that harm and isolate people with chronic pain, especially those from ethnic and racial minority populations. The Integrating Nonpharmacologic Strategies for Pain with Inclusion, Respect, and Equity (INSPIRE) Chronic Pain (CP) intervention blends cognitive-behavioral therapy, physical therapy, mindfulness, and pain education, and is delivered by a trilingual mobile app and supported by a telehealth pain coach who coordinates with doctors. The coach will collect and summarize patient reports on pain, depression, anxiety, substance use, and social factors, and share them with healthcare providers. In this project, researchers will create the digital tool and coaching protocol, develop educational and implementation strategies for healthcare providers, and conduct a pilot test. They will then perform a randomized clinical trial to compare INSPIRE to current treatment, analyze its effects, and evaluate outcomes.

Pain in the muscles and surrounding connective tissue (myofascial pain) is a significant and poorly understood health concern affecting hundreds of millions of Americans. There is a great need for tools to assess changes to myofascial tissues in individuals with chronic pain as well as to measure the effect of commonly used therapies. This project will use three imaging tools to look at differences between shoulder tissue in people with myofascial pain compared to those without pain. Using a machine learning approach, this research aims to develop a biomarker signature for myofascial pain, which will be evaluated in a randomized controlled clinical trial based on its ability to predict patient responses to myofascial pain treatments.

Many barriers exist in primary care offices where socioeconomically disadvantaged patients are most often treated. This project seeks to address chronic pain disparities that affect racially diverse, socioeconomically disadvantaged individuals. The study aims to optimize multimodal pain management in primary care clinics for low-income populations. This study includes two group-based models: integrative group medical visits and group acupuncture. These two interventions will be compared to typical treatment to measure both pain interference and social isolation. National experts and patient stakeholders will refine and optimize the design of the study with English- or Spanish-speaking patients with chronic pain in two primary care clinics for low-income populations.

Sickle cell disease is an inherited blood disorder affecting about 100,000 Americans and more than 20 million people worldwide. It is caused by a mutation in the gene for beta-globin that results in the characteristic sickled shape of red blood cells, life-long severe pain, and shortened lifespan. Optimal treatment of  chronic pain from the condition targets psychological factors contributing to pain, such as pain-related anxiety, fear of movement, and depression. This project will interact with patients and their families to revise and test an existing mind–body and behavioral health treatment tool to target the unique needs and preferences of people managing chronic sickle cell disease pain.

Chronic pelvic pain is a debilitating condition that negatively affects the social and sexual quality of life for up to 20% of American women. Pelvic floor muscle (PFM) pain is caused by many factors, as well as by incorrect posture and excessive sensitization of the peripheral nervous system. This project will introduce a prototype of the Chronic Pelvic Pain (CPP) HomeTrainer that monitors, quantitatively and in real time, both PFM activation capacity and muscle interactions between the PFM and hip/trunk muscles and adapts the PFM training to the user’s needs in their own home. The proposed CPP HomeTrainer offers biofeedback to aid myofascial physical therapy and movement pattern training by tailoring the protocol to specifically correct interactions between the PFM and problematic hip/trunk muscles.

More than half of children and adolescents diagnosed with a type of cancer called bone sarcoma experience pain that interferes with daily life. This project will adapt an evidence-based cognitive behavioral therapy mobile app for use with Black and Hispanic adolescents who disproportionately experience pain from this cancer, putting them at risk for opioid misuse. Once fully adapted, this therapy will be paired with a remotely delivered brain stimulation treatment (transcranial direct current stimulation). This research will also examine the impact of patient-reported conditions such as depression, anxiety, and sleep problems, as well as of various social determinants of health, on pain.

About 14% of U.S. adults report experiencing migraine symptoms within any given 3-month period, making it the second most disabling illness in the world. Nonspecific pain medications used in migraine (e.g., acetaminophen, nonsteroidal inflammatory drugs, opioids) are often not effective for severe migraine symptoms or cause significant adverse effects. A research team of migraine care specialists, device and drug developers, and clinical research specialists has created a technology for accurately delivering self-administered migraine medication to the upper nasal cavity. The technology enables development of a self-administered therapy to provide rapid pain relief without harsh and addictive side effects of existing migraine medications. This project will establish efficacy and evaluate commercial design feasibility for this treatment.

Asian American women who have survived breast cancer and who also have depression are less likely to receive adequate pain treatment due to cultural stigma attached to breast cancer, cultural attitudes about living with pain and symptoms, and language barriers. This project will use a personalizable, technology-based approach to treat cancer pain and depression in Japanese American, Chinese American, and Korean American women who have survived breast cancer. The intervention will accommodate flexibility, accessibility, and anonymity: three factors that have historically hindered effective pain management for this population of breast cancer survivors.

Overreliance on opioids to treat chronic pain has been a contributor to the increase in individuals experiencing opioid addiction. This project aims to develop an innovative treatment approach for chronic pain that targets the cannabinoid receptor 1 (CB1R) to block the sensation of pain. The approach seeks to identify molecules that interact with a different part of the CBR1 receptor than do endocannabinoids and the primary active component of cannabis, tetrahydrocannabinol. Molecules that bind to and activate CBR1 in this different way (at an “allosteric” site) may produce nerve signaling that might differ from the effects of cannabis and endocannabinoids. This redirection of signaling pathways could help eliminate the risk of adverse effects observed with natural cannabinoids and other CBR1-binding molecules. The goal of this project is to identify a CB1R allosteric molecule, conduct studies toward obtaining federal permission to develop it as a medication, and to test it in a Phase I clinical study.
