Filter by:To determine whether central sensitization is a mechanism of CPSP (chronic postsurgical pain) in women who will develop CPSP compared to women with no CPSP after hysterectomy. This mechanism is illustrated by a higher pain score in experimental pain models such as tonic heat stimulation, increased evoked mechanical temporal summation and increased wound hyperalgesia.
Oral ketamine is increasingly used by doctors to both reduce the amount of narcotic pain medication consumed and to improve chronic pain management in difficult cases. How much is absorbed when taken orally, as opposed to intravenously ,is unknown. Ketamine may cause sedation, and occasionally cognitive impairment. Therefore, there are safety concerns associated with its usage as an out-patient may engage in activities where cognitive impairment is dangerous,such as driving. This study is designed to measure the plasma concentrations of ketamine and its active metabolite, norketamine, in people taking low dose oral ketamine for chronic pain. The goal of the study is to verify that low dose oral ketamine produces plasma concentrations below the level associated with toxic symptoms,and thus can be safely used long-term for the treatment of chronic pain .
The purpose of the study is to demonstrate the safety and efficacy of the Prodigy system for the treatment of chronic intractable pain of the trunk and/or limbs.
Introduction: Non-specific chronic low back pain (CLBP) is one of the most frequent causes for patient disability and a general recurrent cause for medical consultation with high costs to public health. From rehabilitative medicine, physiotherapy is commonly offered. Although this treatment is aimed to reduce disability, pain severity and pain-related anxiety-depressive symptoms, many patients report partial improvement and recurrent intensive and disabling pain episodes. Therefore, a new approach in the treatment and rehabilitation of this pathology that takes into account psychosocial aspects that might be modulating pain is necessary. Material and methods: This project aims to assess the efficacy of two complementary interventions to standard physical therapy, such as relaxation techniques and cognitive-behavioral intervention, to improve health-related quality of life (HRQoL) among patients with CLBP. It is hypothesized that groups receiving these complementary interventions will significantly improve their adherence to physiotherapy and the control of their pain and, ultimately, these aspects will facilitate a decreasing of pain intensity and better HRQoL. For these purposes, a pre-post longitudinal design will be carried out, with follow-up assessments at 6 and 12 months in a sample of 66 participants. This sample will be divided into: control group (physiotherapy), intervention group 1 (physiotherapy and relaxation techniques-sophrology) and intervention group 2 (physiotherapy and cognitive-behavioral intervention). Expected impact: Study results are not available yet. However, if working hypotheses are confirmed, a multidisciplinary model of care for CLBP will be empirically justified. This approach is expected to benefit HRQoL among these patients implying a significant short-mid term reduction of public health costs.
The study purpose is to examine polymorphism of genes associated to post-operative persistent pain and to verify the possible association between genotype phenotype and ADRB2 polymorphism in orthopaedic surgery. The primary aim is to evaluate the expression of ADBR2 in VAS>4 patients and to compare it to those with VAS<4.
Study Hypothesis: A virtual peer-to-peer support intervention will improve health outcomes and quality of life in adolescents with chronic pain.
Many breast cancer survivors report chronic pain that develops or worsens following chemotherapy. The impact of chemotherapy on the development of chronic pain is uncertain. In this proposal, we are studying the impact of chemotherapy on a patient's sensitivity to pain. We are also investigating whether a patient's sensitivity to pain is related to how many symptoms she experiences during treatment.
The broad aim of the 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. Pain-related fear is an important psychological factor associated with poor outcomes in children suffering with chronic pain. To examine the efficacy of GET Living in addressing pain-related fears the investigators propose to use a sequential replicated randomized single-case experimental phase design with multiple measures. The specific aims are to 1) evaluate the effectiveness and acceptability of individually tailored GET Living for children with high pain-related fear and functional disability and 2) define anatomical and resting state connectivity patterns in the brains of children and adolescents with complex chronic pain prior to and after participation in GET Living.
The objective of this study is to evaluate chronic pain after inguinal hernia repair involving mesh placement with the Onstep-technique compared to mesh placement using a laparoscopic approach. The study hypothesis is that an even or smaller proportions of patients operated the Onstep technique will have chronic pain that impairs daily function.
The purpose of this trial is to evaluate if cebranopadol is safe and can decrease pain in patients when compared to placebo (a tablet that does not contain active product) and when compared to a marketed product containing pregabalin (Lyrica®). Furthermore, this trial will be undertaken to find out if the patient's general health and well-being improves under trial treatment. The concentrations of cebranopadol in the blood will be investigated to get a better understanding of how it is absorbed from the gut, distributed and broken down in the body, and eliminated from the body.
