NCT ID: NCT06416826 Withdrawn - Clinical trials for Chronic Pain, Widespread

Rhythmic Sensory Stimulation on Fibromyalgia

Start date: April 1, 2019
Phase: N/A
Study type: Interventional

The aim of this project is to further examine the effectiveness of Rhythmic Sensory Stimulation (RSS) with low-frequency sounds and somatosensory stimulation as a complementary therapy for fibromyalgia, and to investigate potential mechanisms underlying the effects of RSS on chronic pain.

NCT ID: NCT05478668 Completed - Clinical trials for Chronic Pain, Widespread

Predictors of Pain Chronicity in Patients With Gunshot and Mine-explosive Wounds

PP?PGM-EW
Start date: February 24, 2022
Phase:
Study type: Observational [Patient Registry]

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.

NCT ID: NCT04674670 Completed - Fibromyalgia Clinical Trials

Psychobiological Mechanisms Underlying Chronic Pain

Start date: November 1, 2021
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03915938 Completed - Schizophrenia Clinical Trials

Ketamine's Effect Changes the Cortical Electrophysiological Activity Related to Semantic Affective Dimension of Pain

Start date: January 2, 2017
Phase: Phase 2/Phase 3
Study type: Interventional

This is a clinical trial that intend to determine the effects of S-ketamine on event-related potentials associated with semantic affective pain-processing

NCT ID: NCT03882333 Completed - Clinical trials for Chronic Pain, Widespread

Effects of Acute Exercise on Pain and Human Movement

eMOVE
Start date: December 12, 2018
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03705104 Active, not recruiting - Clinical trials for Chronic Pain, Widespread

Living Well With Chronic Pain

EPIO
Start date: December 3, 2019
Phase: N/A
Study type: Interventional

The goal of this project is to test the effect of an interactive e-health intervention for people with chronic pain.

NCT ID: NCT03699007 Completed - Clinical trials for Musculoskeletal Pain

GET Living: Graded Exposure Treatment for Children and Adolescents With Chronic Pain

Start date: January 23, 2019
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03413501 Completed - Clinical trials for Chronic Pain, Widespread

A Multi-disciplinary Pain Intervention (MUD-PI) for Patients With Chronic Widespread Primary Pain

MUD-PI
Start date: September 20, 2016
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03215940 Recruiting - Clinical trials for Chronic Pain, Widespread

Treatment of Chronic Pain With Cannabidiol (CBD) and Delta-9-tetrahydrocannabinol (THC)

Start date: February 1, 2018
Phase: Early Phase 1
Study type: Interventional

This is a study comparing the effects of Delta-9-Tetrahydrocannabinol (THC) versus Cannabidiol (CBD) versus a placebo on chronic non-cancer pain.

NCT ID: NCT03157362 Completed - Clinical trials for Chronic Pain, Widespread

Effects of Social Presence and Perception in Virtual Reality on Pain

SPP
Start date: February 1, 2018
Phase: N/A
Study type: Interventional

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.
