Active clinical trials for "Chronic Pain"

The goal of this study is to compare pain outcomes achieved by spinal cord stimulation (SCS) using time varying stimulation patterns with pain outcomes achieved by current standard of care SCS.

Chronic pain is a major cause of disability, and given its negative impact on the functional, psychological, and social well-being of sufferers, it is crucial to identify the biopsychosocial factors that influence it. While biological and psychological factors have been extensively studied, the role of the patient's relational context has not been thoroughly investigated to date. The presence of pain affects both directly and indirectly the patient's family and social context, which could significantly influence the perception of pain itself. In particular, partners of chronic pain patients may experience high levels of stress, anxiety, and worry, and this may have an impact on couple satisfaction and the type of partner's responses with respect to the patient's pain manifestations. It is conceivable that the type of interaction between patient and partner is influenced by the intersection of the ways in which the patient expresses pain, such as by manifesting catastrophic experiences, with the type of responses provided by the partner, such as of criticism, distraction, or support. It can be hypothesized that both the partner's actual responses to the patient's manifestations of pain and the patient's satisfaction with these responses are important. This study therefore aims to understand the relationships between these factors. Specifically, it will assess whether attributions and catastrophizing behaviors of the patient influence pain intensity and interference over time through mediation by the responses given by the partner. It will also be assessed whether this mediation is moderated by the patient's satisfaction with the partner's responses.

Chronic pain is pain whose duration usually exceeds a period of three months and standard treatment is ineffective. This pain brings many changes in physical and psychological functioning to the individual and can even lead to a reduction in the quality of life. The main goal of the project is to determine the impact of pain and treatment on the quality of life and patterns of physical activity in patients with chronic pain. Furthermore, evaluate specific changes in quality of life, disability, physical activity, BMI, and body composition after the application of therapeutic and educational measures. Another goal is to validate an assessment tool for assessing the activity patterns of patients with chronic pain. In the first phase, the Czech version of the Patterns of Activity Measures-Pain scale (POAM-P/CZ) will be validated to assess the activity patterns of individuals with chronic pain. Subsequently, a prospective observational study will be carried out with the aim of comparing differences in quality of life, disability, activity patterns, BMI (body composition), and psychosocial variables after the application of targeted treatment measures and educational interventions. The subjective assessment of pain will be supplemented by the assessment of the Analgesia Nociception Index. The results of the project can contribute to the development of effective long-term strategies for the optimization of educational programs to support the self-management of chronic pain and the specific focus of health care.

The aim of this monocentric observational pilot study is to measure the lidocaine plasma level in a limited number of patients to generate explorative data on inter- and intrapersonal stability and safety of drug plasma levels and to investigate whether higher plasma levels of ketamine can be correlated with a better analgesic effect.

The purpose of this study is to conduct a feasibility clinical trial by implementing a 1-session pain relief skills intervention (Empowered Relief; two hours total treatment time) for individuals with Marfan syndrome, Vascular Ehlers-Danlos Syndrome, Loeys-Dietz Syndrome, and related conditions.

This is a pragmatic randomized controlled trial comparing a single 15-minute mindfulness-based intervention to usual care for patients with chronic pain in Ukraine being seen in a pain clinic.

The Conceptualization of Pain Questionnaire (COPAQ), has been presented to the literature in order to evaluate the concept of pain in children and its psychometric properties. This scale, which was developed by Salvat et al., is stated as a tool that consists of a total of 15 items and is easy to administer and respond to. The total score is calculated with the correct or incorrect answers given by the children to these items, and the higher this score, the better the child's understanding of the concept of pain. Moreover; it has been shown that the scale has good fit and internal consistency. In Turkey, there is no valid and reliable scale to evaluate the concept of pain in a child with chronic pain. The aim of this study is to create the Turkish version of "The Conceptualization of Pain Questionnaire (COPAQ)", which evaluates the concept of pain in children with chronic pain, and to question the Turkish validity and reliability of this scale.

This new research projet in pain is enrolled into an international official collaboration between researchers and clinicians from Irmandade da Santa Casa de Londrina (ISCAL) and those from two Quebec universities: University of Quebec in Chicoutimi (UQAC) and University of Quebec in Rimouski (UQAR). ISCAL as a living laboratory research environment (sites, equipment, technology) for researchers, clinicians, students, and patients pool will make this project unique in the world, especially to stablish an integral concept on pain from identification, assessment and management, using neurophysiological central measures across patients with neuromusculoskeletal disorders. ISCAL in partnership with Santa Hospital in Londrina admit so many patients per day suffering of pain, by supporting a specific size of sample for establishment of this integral concept in pain. This project builds on the foundations already well installed at ISCAL for data acquisition and storage, from an ideal set-up including patients with pain and clinicians. ISCAL infrastructure will be used to improve the acquirement of pain data from patients, using high-tech tools in a simple and robust experimental protocol targeting the central nervous system (CNS). Pain conventional evaluation (by questionnaires or simple questions related to pain intensity from anamneses or inspection doctor) will be completed by neurophysiological measures of the CNS activity based on the acquisition of biological signals and related to functional activities of the patients. A specific physiological behavior of pain will be determinate, using different types of preprocessing and statistical analyzes on biological signals. While pain and physical dysfunction mechanisms involve through the CNS, measurements from the CNS will allow to better understand the profiles and needs of the population (active adults and older people) suffering from pain and disabilities. The knowledge acquired throughout this research program will improve the pain care in Santa Casa Hospital, the evidence-based practices (EBP) on site by specialist doctors and health professionals (nursing, medical, physiatry, physiotherapist etc.), and mainly will improve the quality of life of patients with pain. This project is a sharing of expertise beneficial to both poles, including the training of students, the use of advanced technologies and the exploration of new avenues in pain research grounded on the development of ISCAL in an international collaboration perspective. All of the work from this research program aims to make ISCAL the reference center for chronic pain in Paraná (south of country) and further, for all Brazil.

The investigators hope to use MRI biomarkers to identify and characterize sensorimotor network disruption patterns associated with chronic pain and sensory deficits in CP. Investigators will use existing information in the medical record as well as subjective reports from interview, physical exam data, and anatomical and functional MRI data to non-invasively identify brain and spine injury correlates of pain and sensory deficits.

Patients aged less than 18-y with validated 8% capsaicin patch treatment in routine healthcare will be offered to participate the study. If they accept it as well as their parents, they will be included in the study . Medical data will be recorded and at home, the child or his family will collect pain assessment data. Tolerance will be monitored at home by phone call from investigational team every 24 hours until normalization. (Less than 24 hours for 75%, 100% to 72 hours on unpublished personal series.) Children will be assessed via scales at inclusion and 1-month, 3-month and 6-month.
