Pain Clinical Trials

The purpose of this research study is to compare the effects of cannabidiol (CBD), tetrahydrocannabinol (THC), or both, on sleep and pain in persons with multiple sclerosis (MS). Little is known about how CBD and/or THC may help sleep, reduce pain, or perhaps even treat pain through better sleep. Read Less

The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider. Read Less

This study is a double-blind, randomized, placebo-controlled trial to evaluate the use of high frequency TENS for pain control during IUD insertion. Transcutaneous electrical nerve stimulation (TENS) is a relatively low-cost, low-risk, non-pharmacologic intervention for pain management. Previous studies have found that TENS reduces pain associated with other outpatient gynecological procedures. Participants will be randomized in a 1:1 ratio to either active treatment or placebo (placebo TENS) and record pain scores using a 100 mm visual analog scale (VAS) at the time of IUD insertion. The same device will be used for both active and placebo treatment. Read Less

Background: - Painful stimuli cause changes in a network of brain regions called the "Pain Matrix." But most of these regions respond to many other stimuli, not just pain. Researchers want to understand how different factors influence pain. They want to test what happens when people expect different levels of pain and receive treatments that can modify pain. They want to see if these factors influence decisions about pain and how the body responds to it. They also want to compare pain with responses like taste and vision. Objectives: - To better understand how pain and emotions are processed and influenced by psychological factors. Eligibility: - Healthy volunteers ages 18-50. Design: * This study requires 1 to 2 clinic visits that last 1 to 3 hours. * Participants will be screened with medical history and physical exam. * Some participants will have one or more magnetic resonance imaging (MRI) scans of their brain. For MRI, participants will lie on a table that slides in and out of a cylinder. The scanner makes loud knocking noises. They will get earplugs. * Participants heart activity will be recorded with electrocardiogram. Their pulse, sweating, and breathing will be monitored. * Some participants will take a taste test. Others may perform simple tasks. Others may receive pain in their arm, leg, or hand. The pain will come from heat or electric shocks. Others may judge pain using a topical pain-relieving cream. Some of these tests may be given during MRI. * Participants will fill out questionnaires. * The study will last 3 years. Read Less

The Investigators have recently published on differences in pain sensitivity measures between cis and trans individuals in the local area. The investigators observed the anticipated differences in pain sensitivity between CM and CW (CW \> CM), but found that the TW were phenotypically similar to CW in all measures. However, the investigators did not assess hormone level, nor did the investigators recruit TM participants. Here, with the assistance of two local community group stakeholders the investigators will recruit the following groups: CM, CW, TM+T (currently taking exogenous testosterone), TW+E (exogenous estradiol), TM, and TW (n=20/group). The investigators will use quantitative sensory testing to assess sensitivity to cold, pressure, and heat via standardized protocols. Blood samples will be taken for assessment of stress and reproductive hormone levels, immune cell populations and stimulated cytokine release. Finally, questionnaires will measure pain state, quality of life (QOL), voice QOL, body image, appearance, self-reported health, masculinity/femininity, community connectedness, gender role, sleep, depression, social support, adverse childhood experiences and stigma.

Objective The current proposal investigates behavioral, psychophysiological, and social processes that may help explain biases and disparate outcomes in pain. Health disparities, or health outcomes that adversely affect disadvantaged populations, are pervasive and apparent in many diseases and symptoms, including pain. Pain is the number one reason individuals seek medical treatment. Health disparities in pain encompass both differences in pain experience and treatment for pain. For instance, research indicates that Black individuals report increased pain and have reduced pain tolerance relative to White individuals, yet doctors are less likely to treat minority patients pain and underestimate their pain experience. This project aims to address this systemic discrepancy by focusing on interpersonal processes that may contribute to these disparities, including socially-relevant responses to pain (i.e. pain expression) and pain assessment (e.g. visual attention). The proposed research aims to determine whether the study of pain expressions and their assessment can yield insights on how social factors shape pain and its treatment. Further, we test the efficacy of potential interventions designed to improve accuracy and reduce biases in pain assessment. If successful, this work will form the foundation of a new research program that will link the field of pain research with the field of social neuroscience, and forge new insights on the critical problem of health disparities in pain. Study population We will accrue up to 700 total healthy volunteers to target 262 completers Design Our overall aim is to understand how social factors influence the assessment and management of pain, and to gain insight into psychosocial processes that may underlie health disparities in pain. We propose a series of studies designed to test these links. First, we will measure pain perception and physiological responses to painful stimuli in a diverse group of individuals to test for sociocultural and biological influences on pain and pain-related responses. In subsequent studies, new participants ("perceivers") will view images of these initial participants ("targets") and will provide estimates of 'targets' pain experience. We will measure a) whether perceivers can accurately estimate 'targets' pain experience; b) whether accuracy differs as a function of similarity between target and perceiver (ingroup vs outgroup); and c) whether individuals can improve accuracy through feedback. Outcome measures Primary outcome measures for all experiments will be decisions about pain (experienced by self or other) measured with visual analogue scales, reaction time, and/or categorical judgments (pain/no pain). We will also measure physiological responses (e.g., facial muscle response, skin conductance, pupil dilation) and brain responses using functional magnetic resonance imaging (fMRI) as secondary outcome measures. We will test whether pain and pain-related responses varies as a function of sociocultural/demographic factors (e.g. race, ethnicity, sex) and whether accuracy in assessing others pain is influenced by group similarity (i.e. ingroup vs. outgroup) and training (e.g. performance-related feedback)....

Endometriosis is a common cause of pelvic pain in women which has been historically under-studied and under-diagnosed. The goal of this research is to pilot-test the feasibility and acceptability of a manualized, single-session brief mindfulness-based intervention (BMBI) among participants with endometriosis-related chronic pelvic pain (ECPP) who undergo surgical treatment, and gather preliminary data necessary for future studies assessing BMBI's impact on outcomes in surgically-treated ECPP. This pilot study will enroll 10-20 adult participants with ECPP to receive either a BMBI adjunctive to treatment as usual (TAU; n=5-10) or education with TAU (n=5-10) prior to their ECPP surgery. The central hypothesis is the BMBI is feasible to deliver pre-operatively, acceptable to patients, and may help improve acute post-surgical outcomes through more adaptive stress coping and pain processing, enabled by mindfulness training.

There are close to 700,000 survivors of adolescent and young adult (AYA) cancer (aged 15 to 39 at diagnosis) in the US. Survivorship for AYAs is often complicated by long-term and late-effects. Cardiovascular disease (CVD), in particular, is a leading cause of death for cancer survivors and is a growing public health concern for survivors diagnosed as AYAs. Risk of CVD may be associated with treatment exposures and may be potentiated by weight gain and poor health behaviors. Healthy eating and physical activity are key behaviors for weight loss and maintenance and may be protective against CVD risk, yet few AYA cancer survivors adhere to guidelines for healthy eating or activity. AYA survivors' abilities to engage in health behaviors (i.e., healthy eating, physical activity) necessary to manage weight may also be challenged by persistent cancer-related symptoms (i.e., pain, fatigue, psychological distress). Thus, weight gain is common. Using input from AYA cancer survivors, the investigators have adapted a behavioral weight and symptom management protocol for AYA cancer survivors with obesity to create an intervention that is responsive to AYAs' unique needs. A pilot randomized controlled trial will be conducted to examine intervention feasibility and acceptability and to examine patterns of change in outcomes including weight, body mass index, symptoms (e.g., pain, fatigue, distress) as well as other CVD risk factors, including blood pressure, cholesterol (total, HDL, LDL), HbA1c, and atherosclerotic cardiovascular disease (ASCVD) risk score.

Background: Researchers want to better understand pain by studying people with and without different kinds of pain. To do this, researchers will expose people to pleasant and unpleasant sensations. They will ask them questions about their pain. Researchers also want to see if these people are eligible for other research studies at the National Center for Complementary and Integrative Health. Objectives: To study the experience of pain. Also to find people eligible to join other NIH studies. Eligibility: People 12 years and older with and without pain disorders. Design: Participants will be screened by phone. Participants will have one required visit lasting about 2 hours. This may include: * Medical history * Physical exam * Questionnaires about themselves and their pain experience * Blood and urine tests * MRI: They will lie on a table that slides into a cylinder. They will feel different sensations while completing tasks on a computer. This lasts 15 minutes to 2 hours. * Quantitative sensory testing: They will be exposed to different pictures, sounds, tastes, and smells. They will also be exposed to pleasant and unpleasant sensations. These could include: * Burning, itching, or cold sensations * Pinpricks * Pressure and pinches * Electrocardiogram: Stickers on the chest record heart activity. * Straps placed around the chest to measure breathing. * Small sensors on the fingers or palms to measure pulse and sweating. Participants may have up to 12 other outpatient study visits. Participants may be recorded at the visits. Read Less

The overall objective of this study is to determine the feasibility of identifying transdiagnostic biomarkers of cognitive function mediated by neuromodulation of the dorsolateral prefrontal cortex that are translatable across disease groups in order to more accurately phenotype clusters of cognitive dysfunction. Completing behavioral paradigms with electrophysiology and TMS is a challenging frontier. This study focuses on the feasibility of such an endeavor for those with chronic pain or depression as well as healthy controls. Read Less
