Active clinical trials for "Chronic Pain"

Chronic pain is a significant burden to the individual and society with post-surgical pain identified as a research priority for the speciality of anaesthesia. The objectives are to explore the relationship between IENFD and pain after caesarean section and to explore the characteristics of post-caesarean section pain. The hypothesis is that reduced pre-operative IENFD at the surgical site will correlate with risk of developing CPSP.

Questionnaires are available to measure expectations based on patient and treatment expectations in musculoskeletal disorders. In order to elucidate the factors that change expectations in the treatment of pain, more valid and reliable measurement tools are needed to measure the expectations of patients. The validity and reliability made in Turkey, there is no comprehensive study that measures the expectations of treatment. Therefore, the aim of this study was to test the Turkish validity and characteristics of the Chronic Pain Expectations Scale in patients with pain due to chronic musculoskeletal disorders.

A mixed-methods sequential explanatory design study. The first quantitative phase will be a multi-language survey that includes questions related to pain status, patient beliefs, pain interference/social support, and perspective on healthcare utilization. Latent class analysis (LCA) will be used to generate experience-based subgroups in CMP. The second qualitative phase will use focus group will elucidate, confirm, and more richly describe the findings from the first phase.

Chronic abdominal pain is highly prevalent in patients undergoing abdominal surgery. Adhesions are reported to be one of the most common causes of chronic pain after surgery. There is little epidemiological data on the natural course and risk factors of pain. In this study the investigators will assess risk factors for chronic pain and natural course by tracking pain scores through an app in a cohort of 1,500 patients undergoing abdominal surgery. In part two of the study patients with persistent abdominal pain at 12 months, that meet IASP criteria for chronic pain will have clinical investigations to determine the cause of their pain. This investigation includes cineMRI for diagnosis and mapping of adhesions.

Prospective national cohort study of patients submitted to elective inguinal hernia repair. The primary outcome is the prevalence of chronic postoperative inguinal pain, according to the EuraHS QoL questionnaire at 3 months postoperatively. The study will be delivered in all Portuguese regions through a collaborative research network. Four 2-week inclusion periods will be open for recruitment. A site-specific questionnaire will capture procedure volume and logistical facilities for hernia surgery.

The aim of the study is to compare the neutrophils to lymphocytes ratio (NLR), platelets to lymphocytes ratio (PLR), eosinophils to lymphocytes ratio (ELR), red blood cell distribution width (RDW), mean platelet volume (MPV), systemic immune inflammation index (SII), erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) which are the hematological parameters associated with systemic inflammation in acute and subacute/chronic low back pain. Secondary purpose; evaluation of the prognostic roles of hematological parameters associated with systemic inflammation in low back pain in predicting chronicity.This study is a retrospective case-control study. The data of patients who applied to the emergency department with the complaint of acute (less than 4 weeks) low back pain or to the Physical Medicine and Rehabilitation outpatient clinic with the complaint of subacute (lasting 4-12 weeks) or chronic (longer than 12 weeks) non-specific low back pain in the last 3 years will be scanned. The data of patients who applied with complaints other than medical conditions known to be associated with painful conditions and/or inflammatory response will be screened as a control group. The data of patients between the ages of 18-65 will be included in the study. In conclusion, the data of 150 patients who presented with acute non-specific low back pain, 150 patients who presented with subacute/chronic non-specific low back pain and 150 participants as the control group will be included in the study for use in analysis. Participants' age, gender, duration of low back pain (days), if evaluated, conditions associated with low back pain in cases with subacute/chronic pain, ESR, CRP, RDW, MPV, neutrophil count, lymphocyte count, eosinophil count and platelet count in blood tests at admission examinations will be recorded. NLR will be calculated by dividing the number of neutrophils by the number of lymphocytes, PLR by dividing the number of platelets by the number of lymphocytes, ELR by dividing the number of eosinophils by the number of lymphocytes, and SII by the formula "platelet numberxneutrophil number/lymphocyte number".

The chronic widespread pain (CWP) and fibromyalgia (FM) cause serious discomfort, but at the same time they are not life threatening and they cannot be detected by any laboratory tests. The problems connected with these conditions have gained little attention in Estonia so far. It can be assumed that the CWP and FM often remain undetected and the sufferers live without treatment they need. So far, there are no data on the prevalence of the CWP and FM in Estonia available. The goal of the current research is to assess the prevalence of the CWP and local pain syndromes among Estonia's RA patients and among the control population in Tallinn and Harju County; also the factors connected with the presence of the pain and the pain treatment in use. At the same time there will be a similarly designed research conducted in Jyväskylä Central Hospital, which provides the opportunity to compare results in Estonia's and Finland's research groups. The study on the distribution of the chronic pain among RA patients and control population will allow to assess the magnitude of the problem in Estonia and to raise the awareness of physicians about CWP and significance of its treatment. Performing the study will provide an experience which forms the base for further epidemiological and clinical research on CWP and FM

The authors propose to evaluate the prevalence of chronic post-operative pain (CPOP) and continued opioid use in the population that has undergone cardiac surgery at the Montreal Heart Institute. In addition, the authors wish to evaluate the presence of known risk factors for CPOP in this population.

Immersive Virtual Reality is a fast developing technology that allows a number of opportunities to engage people in activities that they otherwise might find difficult. For instance exercising in a fun way when they have difficulty exercising in the way they previously enjoyed. Alternatively the immersive nature of the experience might make it easier to engage in tasks in an otherwise distracting world. The investigators are interested in exploring how Virtual Reality games and programs can help people with Chronic Pain. Working with Researchers at Sheffield Hallam University the research team introduced Virtual Reality headsets and games to people engaging in a Pain Management Program Group lasting 6 weeks for 3 hours a week. This involved NHS patients in the UK, delivered by a physiotherapist and an occupational therapist. This group involved 8 individuals with a variety of chronic pain conditions. Patients used Virtual Reality headsets and games throughout the program to aid exercise and mindfulness activities. This is a relatively new approach and the investigators are not aware of any other organisations making use of this technology in this way. It would be useful developing its use to explore the issues those leading the Pain Management Group and supporting patients found. Speaking to these individuals in interviews will explore their experiences and feelings deeply and allow us to learn about what worked well and what challenges they faced. These interviews would be conducted in a format of qualitative research that would explore the experiences staff had, and compare it to other experiences of introducing patient-used technology in healthcare.

Neuropathic pain, described as 'pain arising as a direct consequence of a lesion or disease on the somatosensory system', affects up to 3-9.8% of the investigators' population, but is often underdiagnosed and undertreated. As treatment is different for patients with neuropathic pain and nociceptive pain, it is important to screen for neuropathic pain. Commonly employed questionnaire-based diagnostic tools in English speaking countries include the Leeds Assessment of Neuropathic Symptoms and Signs pain scale (LANSS) and Neuropathic pain questionnaire (NPQ). Self-completed LANSS is particularly useful as it is not restricted to clinician's examination and can be applied in large-scale research. S-LANSS has been successfully translated, validated and used successfully in Arabic and Turkish, but it has not been utilised in the Chinese population. As verbal translations of the English questionnaires used at the bedside may be prone to errors in interpretation and requires medical practitioners to interpret the questions. Therefore a translation and validation study is essential.
