Filter by:Performance Validity Tests (PVTs) are widely used for the detection of sub-optimal effort and malingering in neuropsychological assessments. Threats to their validity however likely to intensify with time (e.g., information available on the web or from legal representatives) and may lead to a decline in their ability to differentiate between malingerers and non-malingerers. Eye movements and response time (RT) are less obvious outcome measures and under less conscious control than more conventional PVT indices (e.g., accuracy). They are therefore promising measures that can aid in detecting malingering when used in conjunction with more conventional PVT indices. The Word Memory Test (WMT) is a widely used PVT in neuropsychological evaluations. As part of the proposed study, TBI patients, chronic pain patients and healthy adults (60 in each group) will be randomly divided to one of two conditions; optimal effort or sub-optimal effort (participants will be asked to play a TBI patient who wishes to present himself as having cognitive deficits or exaggerate existing cognitive deficits). The proposed study will improve the WMT's efficacy in detection of sub-optimal effort in neuropsychological evaluations and therefore protect its validity from future threats. In addition, the proposed study will provide us with better understanding of the effect of TBI on eye movements and RTs in general.
The aim of the study is to investigate whether pre-operative dysregulated systemic lipid mediator pathways are associated with increased risk for the development of persistent post surgical pain. In addition we will investigate whether treatment with an over the counter dietary supplement containing a fractionated marine lipid derivative from anchovy and sardine oil prevents the development of chronic pain after surgery.
Fibromyalgia pain syndrome is a common debilitating condition which associates mainly generalised pain, emotional distress and cognitive symptoms. The etiology is unknown, and no specific treatment exists so far. Lately, shock-waves have been used successfully to treat painful skeletal muscle, tendons and fascia, the investigators therefore hypothesize that shock-waves could be useful in alleviating Fibromyalgia pain. Two similar groups of participants bearing the condition will be prospectively compared. The first group will benefit from the application of shock-waves weekly for 12 weeks, the second will not. The investigators intend to study if there is any difference in pain and quality of life between the two groups at the end of the three months.
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.

This study compare the "Serratus block plane" (SPB) and the local infiltration of the tissue in the prevention of acute and chronic pain after breast cancer surgery.
Interventional pain management for back and neck pain is widely used, but the indications and relative merits of these techniques rest subject to discussion. This study aims to identify prognostic criteria for patients who might specifically benefit from interventional pain management. Specifically, the nociceptive reflex threshold will be investigated, which is a measure of central sensibilisation and thus a potentially important prognostic factor.
Using a comprehensive prospective clinical study design, the investigators intend to compare changes in health-related markers in patients with chronic widespread pain (CWP), undergoing one of two intervention "packages" of multimodal health care, namely anthroposophical integrative care (AIC) or standard care (SC), respectively. AIC combines evidence-based conventional care with complementary/alternative (CAM) treatments. As markers, the investigators will use indicators of drug utilization and sick leave, as well as constructs mirroring possible changes in psychological and existential factors and genomic stability (such as telomere length and telomerase levels).
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.
3VM1001 is a topical cream that may be useful for the treatment of chronic osteoarthritis of the knee. This proof of concept study is a randomized, placebo-controlled, double-blind study to compare treatment with 3VM1001 cream to an inactive cream placebo. Subjects will self-treat for 30 days.
