Filter by:The overarching goal of this study phase, Phase I component is to configure Computerized Chemosensory-Based Orbitofrontal Networks Training (CBOT) into Computerized Chemosensory-Based Orbitofrontal Networks Training for Treatment of Pain CBOT-Pain (or CBOT-P) for rapid and sustained reduction of Pain, Negative Affect (NA) and Cognitive Impairments. The investigators aimed at first establishing if stimulation parameters targeting key olfactory regions, and their associated networks, paired with tasks that synergistically activate the orbitofrontal cortex (OFC) would have significantly different acute (< 7 days) effects in pain and NA intensity reductions. The hypothesis is that the short burst paradigm will more effectively activate the medial OFC and its functional connectivity with medial temporal affective networks, and result in greater reduction of affect and pain severity ratings after 7 days. The investigators will further examine if enhancing the odor regimen with beta-caryophyllene (BCP) content would have more dramatic effects in acute relief of pain, NA, and cognition. Aim 1.1: To optimize CBOT-P stimulation parameters and olfactory stimulants for pain, affect and cognition in CP with and without high NA. This is a 14-day prospective study, in which fMRI and rs-fMRI will be acquired at baseline and day 7 during exposure to short vs long-burst CBOT stimulations. This is followed by daily treatment with short-burst versus long-burst CBOT paradigm over 14 days, during which pain and NA measures will be recorded daily by the subjects, and assessed by train research staff at baseline, day 7 and day 14. Aim 1.2: To determine if CBOT regimen optimized with BCP content produces stronger and faster pain and affective response. This is a 14-day prospective study design, in which daily treatment of CBOT-PLUS (i.e., CBOT with BCP) will be compared against daily treatment with CBOT without BCP enhancement (CBOT). Subjects and clinicians are blinded to the assigned arms. Pain and NA measures will be recorded daily by the subjects and assessed by trained research staff at baseline and day 14.
The goal of this non-significant risk study is to determine whether stimulation with transcutaneous waveforms applied on the outside of the body and subcutaneously conducted to the lumbar medial branch nerve elicits visible (via ultrasonic imaging) or palpable multifidus muscle activation within the short-term (<28 day) placement of the Neuronoff PNS Injectrode F1 in healthy volunteers. The main questions it aims to answer are: - Can the PNS Injectrode F1 be safely inserted on the lumbar medial branch nerve for up to 28 days? - Can the PNS Injectrode F1 be safely used to stimulate the lumbar medial branch nerve to activate the multifidus muscle? Participants will - Receive transcutaneous stimulation of the lower back prior to device placement, after device placement, and prior to explant - Insert the PNS Injectrode F1 device on the lumbar medial branch nerve - Have the device inserted for up to 28 days and then explanted - Visit Schedule: Screening/Enrollment, Day 0, Day 2 (email), Day 25, 2 Days Post Explant (email), Day 35
Pain affects the athlete's sporting career directly or indirectly. Directly, the injury affects other areas of the body causing a physical decompensation in the athlete and this affects the correct execution of the sporting technique, or how technical gestures can cause pain. Indirectly, through the psychological consequences of pain that generate a series of negative consequences and feelings. Some studies suggest that psychological skills are an important tool for pain management. For that reason, a mindfulness intervention programme would be a useful tool for manage pain in this population.
Facet joint-related pain is one of the leading causes of low back pain. Facet joint-related disorders can have a negative impact on quality of life and daily living activities, in addition to the pain.Conservative treatment methods such as analgesic medications, physical therapy, and manual therapy are used for facet joint-related low back pain, and interventional pain management practices are used in patients who do not respond adequately to these treatments. Pulse radiofrequency application, which is a recent popular treatment in interventional pain management, is also frequently applied in the treatment of facet-joint related pain. Pulsed radiofrequency intervention can be applied directly intra-articularly or can be applied to the median branch, which is important structure in pain transmission. Although both methods are frequently used in pain management, there is a lack of information in the literature about which is more effective. This study aimed to compare the treatment results of intraarticular pulse radiofrequency application and median branch pulse radiofrequency application in facet joint-related low back pain.
Virtual reality systems have been applied in recent years to reduce pain intensity and fear of movement in individuals with acute and chronic pain. The main mechanism of virtual reality methods in pain control is to provide the effect of distraction from pain. Virtual reality systems allow the individuals to feel themselves in a different environment and shift their attention to the game they are playing or the virtual world created rather than the pain they feel. This is thought to be the main mechanism of pain control. However, the cortical mechanism of the reduction in pain caused by virtual reality methods, especially in individuals with chronic pain, has not been fully elucidated. It is predicted that the integration of virtual reality methods into treatment protocols will gradually increase by time, especially as a result of the reflection of technological developments in clinical practice. At this point, fNIRS, which enables the assessment of the functionality of brain areas during movement, has the potential to reveal the response of the effect provided by virtual reality technology in the prefrontal cortex. The aims of our study were to examine brain hemodynamic activity during the experience of non-immersive and immersive virtual reality environments and the change in pain intensity after virtual reality applications in individuals with rheumatic diseases with chronic pain.
The goals of this study are - To define what the public perceptions of persistent pain using a national survey - Explore relationships between the reported pubic beliefs and demographic factors collected. - To evaluate the impact of a public health campaign to increase awareness of persistent pain and develop understanding of pain that aligns with contemporary science.
Although the cause of persistent non-specific low back pain (LBP) remains unknown, structural and functional alterations of the brain, alterations in the lumbar muscles and dysfunction of the central nervous system have been proposed as underlying mechanisms. In this case-control study, 1) brain structure/function, 2) lumbar muscle function and 3) central pain processing are compared across four groups: 1) healthy participants, 2) recurrent LBP (both during pain flare and during pain remission), 3) chronic LBP and 4) fibromyalgia. According to previous research, healthy participants and fibromyalgia patients are two extremes of a "musculoskeletal pain continuum". Healthy participants representing one extreme of the continuum with no pain and fibromyalgia representing the other extreme of the continuum with chronic widespread pain. It is thought that different LBP populations (i.e. (sub)acute, recurrent, chronic LBP) float between the aforementioned extremes. Past studies already highlighted the need for studies comparing the pathophysiological mechanisms for different pain syndromes to identify common underlying mechanisms across pain syndromes. For this reason, the goal of the current study is to compare alterations in brain structure/function, alterations in lumbar muscle function and alterations in central pain processing across the aforementioned "musculoskeletal pain continuum". It is hypothesized that longer duration of pain (recurrent vs chronic) and the extensiveness of the pain (one location vs widespread pain) are associated with more pronounced alterations in 1) brain structure/function, 2) lumbar muscle function and 3) central pain processing.
The goal of this observational study is to investigate how adverse experiences during childhood are linked to people experiencing persistent pain and fatigue in adulthood. The questions the investigators aim to answer are: 1. Does participant-reported childhood adversity predict levels of IL-6 and TNF-α after in vitro provocation of whole blood using endotoxin? 2. Do levels of IL-6 and TNF-α after in vitro immune provocation using endotoxin predict vulnerability to persistent pain and fatigue after in vivo immune provocation (tetravalent influenza vaccine)? 3. Do levels of IL-6 and TNF-α after in vitro immune provocation using endotoxin predict vulnerability to persistent pain and fatigue after in vivo neural provocation? For this study, the investigators will recruit and enrol 96 healthy human adults (18 - 65 years old) with a range of adverse experiences during childhood. Participants will attend 2 study sessions during which the investigators will take a sample of blood, assess pressure pain threshold before and after cold water immersion, assess heart rate variability, and assess the surface area of secondary skin hypersensitivity after electrical stimulation. At the end of the first session, participants will receive the influenza vaccination.
Pain is an unpleasant sensation common to all those who undergo surgery. Several studies indicate that 40-60% of patients experience the post-operative experience and can be caused by both internal and external stimuli. Chronic post mastectomy pain is a condition characterized by pain in the anterior chest, armpit, and/or upper arm, usually ipsilateral to surgery, which begins after mastectomy or quadrantectomy and persists for longer three months after surgery. It can become chronic in a broad spectrum of conditions. Psychosocial factors such as anxiety and catastrophizing are being revealed as crucial contributors to individual differences in pain processing and outcomes. Some researchers have reported the associations between the development of persistent pain catastrophizing and depression or psychological distress and reduced physical activity. Taken together, these symptoms may lead to disability and worsened quality of life. Due to its benefits, the American Cancer Society recommends to begin as soon as possible from the diagnosis of cancer, physical activity. Aim of this prospective observational study is to evaluate the effects of motor and/or sports activity on the intensity of chronic pain and in symptoms of depression and anxiety, caused by post-mastectomy chronic pain. of life of women underwent mastectomy.
The goal of this pilot quasi-randomized study is test the feasibility, acceptability, and initial efficacy of Yoga for Warriors treatment program for comorbid chronic pain and PTSD, conducted virtually through the Richmond Veterans Affairs Medical Center (RICVAMC). the main questions it aims to answer are: 1. Whether a virtual intervention for chronic pain and PTSD is feasible and acceptable for veterans. 2. Using a wait-list control group design, to determine preliminary efficacy of the intervention. 3. Examine follow-up data to determine if benefits are maintained over time.
