Filter by:82.1% of patients with gunshot and mine-explosive wounds during hostilities in Ukraine have negative results of pain treatment, which leads to its chronicity. Identifying predictors of pain chronicity in these patients may improve their treatment outcomes.
Pain is a powerful motivator of behavior and it is more than the perception of nociceptive input. It is a complex experience that comprises different components: sensory discriminative, emotional-motivational and cognitive components. In chronic pain, a negative hedonic shift has been proposed that is characterized by disproportionally increased emotional-motivational compared to sensory-discriminative pain components. Such a negative hedonic shift is mirrored in a high comorbidity of chronic pain with affective disorders like depression and anxiety. However, the neurobiological mechanisms underlying such a negative hedonic shift i remain elusive. Animal work suggests an involvement of neuroinflammation, caused by chronic pain, which in turn is related to impaired release of the neurotransmitter dopamine. In line with this observation, impaired dopamine functioning has been described in chronic pain. Importantly, dopamine acts also as a neuromodulator, regulating functional connectivity between brain regions. Therefore, dysfunctional dopamine in chronic pain, possibly caused by neuroinflammation, might lead to altered blood oxygen level dependent (BOLD) response and functional connectivity. Correspondingly, altered functional connectivity in fronto-striatal brain networks has been shown to be predictive of transition from subacute to chronic pain. The aim of this study is to investigate the psychobiological mechanisms underlying the negative hedonic shift in chronic pain with a focus on the role of dopamine in functional connectivity of fronto-striatal brain networks, BOLD response of frontostriatal regions and their relation to heightened emotional-motivational pain processing.
This is a clinical trial that intend to determine the effects of S-ketamine on event-related potentials associated with semantic affective pain-processing
The aim of this research project is to evaluate the effect of an acute exercise intervention on pain intensity and movement control. It also aims to investigate potential differences in movement con-trol between patients with chronic musculoskeletal pain compared to healthy controls.
The broad aim of this study is to implement and evaluate the efficacy of Graded Exposure Treatment (GET Living) to target elevated pain-related fears in children with chronic pain at the Stanford Pediatric Pain Management Clinic (PPMC). The investigators will evaluate the effectiveness and acceptability of this intervention for children with high levels of pain-related fear and functional disability. If proven efficacious, it will allow for the dissemination of this innovative treatment model to others working with children and adolescents with chronic pain.
Patients who fulfilled inclusion criteria and consented to participate received either treatment as usual at the clinic, or were enrolled in a group-therapy based intervention, the multi-disciplinary pain intervention, led by a Medical doctor, physiotherapist and psychologist at the clinic.
This experiment aims to examine the effects of transportation via social presence in "near" and "far" virtual environments, on pain threshold in two groups: 1. healthy volunteers in an induced pain task, and 2. older adults suffering from pain. In the first, pilot group, a within-subjects study, participants will complete a series of induced-pain heat ramps in virtual environments that are "near" or "far"-in other words, they will either duplicate their actual physical environment, or represent another location. A second factor in this experiment will be mediated social presence, in which participants interact with confederates as avatars in either condition. The hypotheses follow: H1: Participants who feel present in a remote location will have a higher pain tolerance than those in a near location. H2: Participants who feel socially present with a confederate will have a higher pain tolerance than those who are alone in a virtual environment. H3: There will be an interaction between social presence and virtual environment such that participants who feel socially present in a remote location will have the highest pain tolerance overall. Building on these results,the next step will be a long-term study on older adult pain patients. In this step, the most successful condition in the first study to lightweight, portable headsets that can be used outside of the lab environment. This intervention will be tested on older adult patients who are suffering from chronic pain.
Does the Navigator Tool Intervention improve communication regarding self-management during consultations between healthcare professionals and people with chronic pain? As there is usually no cure for chronic pain, healthcare professionals are increasingly turning to methods of treatment that emphasise management of symptoms rather than elimination of pain. However, as Pain Concern's previous research has shown, there are several barriers to self-management that both healthcare professionals and people with pain face in their consultations in primary care. The Navigator Tool Intervention has been designed to overcome the majority of these barriers through improving the quality of communication regarding self-management during consultations. In line with the House of Care Model, where care relies on engaged and informed patients, healthcare professionals committed to partnership working, and organisational processes that support this, our intervention prepares both the healthcare professionals and patients for their consultation. By providing a training session for the healthcare professionals in how supported self-management can be brought into the consultation room, and by providing the patients with a paper-based tool that allows them to organise their concerns and questions prior to the consultation, the intervention aims to steer the conversation toward the aspects that the patient needs to discuss in order to better manage their pain. This study will launch the intervention and evaluate its effectiveness in improving self-management support through conversation. It will be launched over a 3 month period in 4 sites across Scotland; 24 patients will be using the tool with a trained healthcare professional and 24 will act as a control group, receiving standard care without the tool. Questionnaires assessing the satisfaction with the consultation(s) and communication, as well as confidence in managing one's pain, will be analysed and compared between the two groups. Interviews will be carried out with healthcare professionals and a sample of patients having used the tool to gain a deeper understanding of the usefulness of the intervention and how it may be improved in the future.
