Active clinical trials for "Chronic Pain"

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.

purpose of this study is to evaluate the level of pain perceived by patients using a transdermal cream and/or transdermal patch with or without an oral medication as a pain management solution.

The purpose of this study is to evaluate quality of life, sleep and fadigue in patients with chronic pain using an Item-Response Theory methodology and also generating a Computer Adaptive Testing System

The purpose of this study is to determine whether the metabolite concentrations within the anterior cingulate cortex and periaqueductal gray matter predict the intensity and interference of neuropathic pain after the development of chronic whiplash syndrome.

Resting state fMRI scans of chronic pain sufferers will be compared to those of healthy normals and may be sufficiently different to allow a high level of classification accuracy of whether subjects have chronic pain. In addition, investigators will utilize DTI and a brief activation state using pain rumination to assess whether investigators can reliably find differences between chronic pain sufferers and healthy normals.

FK506 (tacrolimus), a calcineurin inhibitor, is widely used as an immunosuppressant to lower the risk of organ rejection after organ transplantation, and to treat T cell-mediated diseases such as eczema and atopic dermatitis. FK506 treatment often accompanies pain sensation in patients with atopic dermatitis or after organ transplantation. In previous studies, we confirmed that FK506 treatment increased neuronal activity of primary afferent neurons and causes pain behavior in naïve mice. In order to further search for objective clinical evidence, we proposed to investigate pain incidence after FK506 immunosuppressive therapy in liver transplantation patients. We will investigate pain incidence and pain intensity in patients who underwent liver transplant from September of 2011 to May of 2018 in the Liver Health Rehabilitation Association. The patients who were divided into two groups based on whether or not FK506 was used in the immunosuppressive therapy. The patients in control group (without FK506 treatment) and FK506-treated group report pain sensation 3 months and 12 months after liver transplant. We will compare the pain incidence between the two groups at both time points. On the other hand, we will further investigate changes in pain sensation after 1st and 2nd reductions of FK506 dose. Pain is reported subjectively by the patient using the visual analogue scale (VAS) 1 month after dose reduction. In our study, 1st and 2nd reductions of FK506 dose refers to the first two dose-adjustments (approximately 6 months apart) that occurred 3-6 months after the liver transplantation.

This case-control study focuses on pain in HIV, which is common despite antiretroviral therapy and compromises quality of life, mental health and daily functioning. Specifically, it will investigate the relationships between psychosocial distress, inflammation and pain in HIV.

The aim of this study is to explore the association between pain intensity and heart rate variability in patients with chronic pain.

Previous studies have reported that asthmatic or chronic pulmonary obstructive disease patients have an increased response to pain stimulus. However, this aspect has not been evaluated in allergic patients. Additionally, the difference in pain sensitivity between asymptomatic period crisis have not been evaluated yet.
