Effect of Rebound Pain on Chronic Postsurgical Pain After Total Knee Arthroplasty

This prospective observational study aims to evaluate whether rebound pain after peripheral nerve block is associated with the development of chronic postsurgical pain following elective total knee arthroplasty. Adult patients undergoing unilateral total knee arthroplasty under spinal anesthesia and receiving a peripheral nerve block as part of routine multimodal analgesia will be included. No additional intervention, drug administration, or biological sampling will be performed beyond standard clinical care. Rebound pain will be assessed during the early postoperative period using pain diaries, numeric rating scale pain scores, and analgesic consumption records. Chronic postsurgical pain and related outcomes will be evaluated at postoperative 3 and 6 months using validated instruments assessing pain severity, neuropathic pain features, psychological status, functional outcomes, and health-related quality of life. The primary outcome is the presence of chronic postsurgical pain at 3 months after surgery. Secondary outcomes include chronic pain at 6 months, pain intensity, neuropathic pain characteristics, opioid consumption, rescue analgesic requirements, sleep disturbance, and quality-of-life measures. The study also aims to explore demographic and clinical factors associated with rebound pain and chronic postsurgical pain.

Closed-loop Deep Brain Stimulation to Treat Refractory Neuropathic Pain

Deep brain stimulation (DBS) holds promise as a new option for patients suffering from treatment-resistant chronic pain, but current technology is unable to reliably achieve long-term pain symptom relief. A "one-size-fits-all" approach of continuous, 24/7 brain stimulation has helped patients with some movement disorders, but the key to reducing pain may be the activation of stimulation only when needed, as this may help keep the brain from adapting to stimulation effects. By expanding the technological capabilities of an investigative brain stimulation device, the investigators will enable the delivery of stimulation only when pain signals in the brain are high, and then test whether this more personalized stimulation leads to reliable symptom relief for chronic pain patients over extended periods of time.

Weighted Blanket Use for Adults With Chronic Pain

Chronic pain is a common condition that can affect sleep, daily functioning, and overall quality of life. Many individuals living with chronic pain seek non-medication approaches to help manage their symptoms. Weighted blankets are commonly used to promote relaxation and comfort during sleep, but there is limited research examining their potential role in supporting people with chronic pain. This pilot study will explore the experiences of adults with chronic pain who use a weighted blanket during sleep. The study aims to better understand whether nightly use of a weighted blanket may be associated with changes in pain, sleep, and daily functioning. Findings from this study will help inform future research on non-medication approaches to managing chronic pain. Approximately 44 adults with chronic pain will participate in the study. Participation will last about five weeks. After completing a virtual enrollment visit and baseline questionnaires, participants will receive a weighted blanket sized to approximately 10 percent of their body weight. Participants will first complete a 7-day adjustment period using the blanket while sleeping. If they tolerate the blanket and use it nightly during this period, they will continue into a 4-week study phase in which they will use the weighted blanket each night. During the study, participants will complete brief online surveys about their experiences and adherence to using the blanket. Pain and quality-of-life questionnaires will be completed at multiple time points, including at the start and end of the study. Participants will also provide feedback about their experience using the weighted blanket. Results from this pilot study will help researchers better understand how weighted blankets may be used by adults with chronic pain and may help guide the design of future studies evaluating non-pharmacologic approaches to pain management.

Patient Retrospective Outcomes (PRO)

This study will evaluate de-identified (anonymous) data in subject medical charts to review the clinical outcomes of various treatment approaches in the treatment of chronic pain.

Neuromodulation + Prolonged Exposure Therapy: Evaluation of a Technology-Enhanced, Integrated Treatment for Pain and PTSD

The purpose of this study is to examine comparative effectiveness of two home-based telemedicine delivered interventions: transcranial Direct Current Stimulation (tDCS) combined with Massed Prolonged Exposure (Massed-PE) vs. Sham tDCS combined with Massed PE, focusing on pain and PTSD outcomes, to determine the comparative effectiveness of the two interventions on process outcomes of patient satisfaction, treatment attrition, and treatment compliance and to explore changes in blood biomarkers associated with stress and inflammatory processes related to pain and PTSD symptom improvements following treatment.

Virtual Reality Treatment for Adults With Chronic Back Pain (VRNT)

Participants with chronic back pain will complete an online Qualtrics eligibility survey. After signing a consent form, eligible participants enter a two-week baseline period ("Baseline Period"), during which they complete two assessments of the Primary and Secondary Outcome Measures and Potential Mediators. After the baseline period, participants are randomized into a Virtual Reality group: VR Distraction-based Therapy or VR Skills-based Therapy, with a 1:1 allocation ratio of participants to each treatment. Both groups receive education on pain neuroscience and complete training on the use of the VR hardware and software. Next, both groups complete an intervention for 8 weeks ("Treatment Period"), after which they return the VR equipment. Several surveys are administered online during the Treatment Period. After the Treatment Period, both groups complete three post-treatment surveys at weeks 8, 20, and 32.

Cohort of Chronic Pain Patients

Chronic pain affects approximately 20% of adults, 50% of the elderly population and over 1.5 billion people worldwide. Societal and economic issues are also crucial, as 60% of people with pain are less able or unable to work and 20% say they have lost their jobs because of pain. The overall cost of chronic pain is estimated at around 300 billion euros in the EU. Unfortunately, current treatments for chronic pain have limited effectiveness and important adverse effects. Pain clinics, which support the most complex and refractory cases of chronic pain, as well as general practitioners and patients expect improvements, both in terms of therapeutic efficacy and organization of care. In order to allow the characterization and a personalized follow-up of chronic pain patients, we have created e-DOL, a smartphone application for patients and a web platform for healthcare professionals in pain clinics. The purpose of this study is to create an e-cohort for the research, and characterization and follow-up of chronic pain patients.

IMPOWR-ME Project 1: Trial of Yoga and Physical Therapy Onsite at Opioid Treatment Programs

This is a pragmatic, open label, randomized controlled trial with 1:1:1 allocation to 12 weeks of: (1) onsite yoga at opioid treatment programs (OTPs), (2) onsite physical therapy (PT) at OTPs, or (3) treatment as usual (TAU). Participants will be 180 individuals with chronic back pain receiving treatment for opioid use disorder (OUD) in community-based OTPs. Through research visits at screening, baseline, and months 1, 2, 3, 6, and 9, the investigators will evaluate pain and opioid use outcomes and implementation outcomes.

LIFU for Chronic Pain

This research project is examining the effects of noninvasive brain stimulation on chronic pain. We believe this study will help us to better understand possible treatments for chronic pain patients. Subjects will undergo functional magnetic resonance imaging (fMRI) and a computed tomography (CT) scan, which is a way to take pictures of the brain and skull. Subjects will receive noninvasive brain stimulation using low-intensity focused ultrasound (LIFU) sound waves, to temporarily change brain activity. Subjects will undergo pain testing using a small device that will increase the temperature of their skin and will rate this pain. Brain signals (EEG), heart rate and rhythm, blood pressure, respiration rate, and skin moisture will be monitored. Subjects will complete behavioral questionnaires. Each study session is expected to take 1.5-3 hours. Total participation takes 10 weeks.

The Long Term Effects of Online Therapeutic Neuroscience Education in Patients With Chronic Low Back Pain

This study aims to evaluate the effects of online Therapeutic Neuroscience Education (TNE) combined with a 6-week conventional physiotherapy program on pain, disability, kinesiophobia, functionality, treatment expectations, and satisfaction in individuals with chronic low back pain (CLBP). The goal is to improve participants' understanding of chronic pain, reduce fear and avoidance behaviors, enhance movement and functionality, and increase treatment satisfaction. The study also seeks to provide a lasting educational resource. TNE focuses on educating patients about pain neurophysiology, aiming to reduce pain, improve function, and shift perceptions about pain through interactive sessions involving diagrams, metaphors, and examples. Despite evidence supporting TNE's effectiveness for chronic pain conditions, no studies have evaluated its online application or long-term effects. The study will include 60 volunteers with CLBP (ages 20-60), randomized into two groups: one receiving conventional physiotherapy and online TNE, and the other receiving conventional treatment alone. The TNE group will participate in six weekly 45-minute online sessions, covering topics like pain neurophysiology, biopsychosocial factors, and pain coping strategies, without addressing anatomical or emotional aspects. Educational materials, including resources adapted from "Why You Hurt" will be presented to the TNE group. Conventional physiotherapy includes hot packs, ultrasound, TENS, and home exercises for both groups. Clinical outcomes will be assessed by a blinded researcher at multiple time points using tools such as pain and disability scales, kinesiophobia measures, functional tests, and questionnaires on treatment expectations and satisfaction. The study is significant for its innovative approach in examining the clinical and long-term effectiveness of online TNE as part of CLBP management.

Investigation of Low-intensity Focused Ultrasound for Human Pain Management

This project examines the effects of noninvasive brain stimulation on pain. The investigators believe this study will help to better understand possible treatments for chronic pain patients. Participants undergo structural imaging, a functional Magnetic Resonance Image (fMRI) and computed tomography (CT). These images are used to align the low-intensity focused ultrasound (LIFU) device which uses sound waves to temporarily change brain activity. Pain testing is done using a small device that will increase/decrease the temperature of the skin. Brain signals are collected using electroencephalography (EEG). Heart rate, blood pressure, and skin moisture will be monitored as well.

Psychological Options for Wellness and Recovery (POWeR) Trial for Veterans With Chronic Back/Neck Pain

The goal of this clinical trial is to learn which treatment works better for veterans with chronic neck or back pain. This study is comparing three treatments: Pain Reprocessing Therapy (PRT), Cognitive Behavioral Therapy (CBT), and usual care (whatever a person is already doing to cope with their pain). The main questions the study aims to answer are: 1. Which treatment works better for lowering pain: PRT, CBT, or usual care? 2. How do the effects of PRT compare with CBT and usual care in terms of pain relief and other factors such as emotional functioning, quality of life, anxiety, and pain medication use? Participants will: 1. Be randomly assigned to receive either PRT, CBT, or usual care. 2. Complete questionnaires about their pain and health. 3. If in the PRT or CBT group, have nine weekly therapy sessions over video calls with a therapist.

Active Coping: Interdisciplinary Program for Chronic Pain, Physiotherapy Unit (Spain)

The goal of this observational intervention study is to evaluate the impact of a multidisciplinary active coping program for chronic back pain in adults referred from Primary Care to the Physiotherapy Unit of Teruel Ensanche. The main questions it aims to answer are: * Does the program improve physical function, measured through gait speed, balance, and chair stand tests? * Does it reduce pain-related psychological factors such as kinesiophobia, catastrophizing, anxiety, and depression? * Does it improve quality of life and sleep quality, and reduce analgesic medication use? Participants will attend group sessions on pain neuroscience education, followed by sessions on healthy habits, nutrition and sleep hygiene and group psychological intervention focused on emotional wellbeing tools, and will complete therapeutic exercise sessions over the course of the program. They will also complete validated questionnaires and physical assessments at three timepoints: at baseline, at the end of the program, and at a 6-month follow-up.

Analysis of the Therapeutic and Clinical Profile of Cannabinoid Treatments: A Real-World Study

What is the purpose of this study? The use of medicinal cannabis has grown significantly in Brazil. However, because many patients use these products through "compassionate use" (when traditional treatments haven't worked), there is still a lack of large-scale data on how these treatments perform in daily life. This study, called CANAREAL, aims to track patients across Brazil to understand if cannabis-based products are truly effective and safe for treating various conditions, such as chronic pain, anxiety, and depression. How will the study work? This is an observational study, which means the researchers will not provide the medication or change the treatment prescribed by the patient's doctor. Instead, we will simply "follow" the patient's journey for 6 months. What will participants be asked to do? Participants will complete online questionnaires at different stages of their treatment. These tools will measure: Quality of Life: How the treatment affects daily well-being. Clinical Evolution: Changes in pain levels, anxiety, and depression symptoms. Safety: Whether the patient experiences any side effects (adverse events). Why is this study important? Unlike controlled laboratory tests, this "Real-World Study" captures the reality of diverse patients with different backgrounds and health needs. The information gathered will help doctors, patients, and health authorities in Brazil better understand the benefits and risks of cannabinoid therapy, leading to safer and more informed medical decisions in the future.

The Effect of Pain Education Group Therapy and Its Impact on Chronic Pain, Kinesiophobia, and Physical Activity

The goal of this clinical trial is to learn if pain knowledge group intervention among chronic pain patients would influence their level of physical activity, pain intensity, depression, kinesiophobia and central sensitization. The main question it aims to answer is: Primary hypothesis: pain education will decrease participants' depression and pain intensity and increase their physical activity. There is no comparison group. Participants will participate in a 6-week pain knowledge intervention where they will be learning about sleep, stress models, physical activity benefits, pain neurobiology, mindfulness, pain medication.
