Filter by:Pain is a major complaint in hemodialysis (HD) patients. Concentrations of parathyroid hormone (PTH) >250 pg/ml are associated with chronic pain. Visual Analogue Scale (VAS) score which is used to assess the pain severity is positively related to PTH levels. This study is aimed to assess the effects of multiple mega dosages vitamin D supplementations in HD patients with chronic pain. It's a single-center, parallel, double-blind randomized control trial that administrations of 576,000 IU once a week of vitamin D3 for 4 weeks or placebo are for 120 eligible subjects. VAS and laboratory tests including serum concentrations of 25(OH)D, calcium, phosphorus, PTH and C-reactive protein will be evaluated.
Patients with chronic pain syndrome (CPS) may develop central sensitization wich may lead to increased pain intensity and lower pain threshold sometimes to the extend of hyperalgesia and allodynia. Furthermore, patients with daily use of opioids may develop opioid tolerance, and to a lesser extent opioid induced hyperalgesia. These factors may lead to a higher pain intensity in the perioperative setting resulting in the observed increased opioid dosage needed to treat the acute pain. Furthermore opioid titration may be difficult with higher levels of pain and a higher risk of opioid related adverse effects incl. respiratory depression and sedation. The factors above advocate for utilizing opioid sparing analgesic techniques. In our department as in many others we use an multimodal opioid sparing approach for surgical procedures including epidural anesthesia (EA) as a standard part of the perioperative analgesia strategy after upper laparotomy, as a sufficient epidural anesthesia has shown to provide a stable and often better pain relief than systemic opioids in these patients. Clinically, there is a suspicion that patients with CPS on fixed opioid treatment have a higher frequency of need for epidural optimization, despite the lack of an anatomical reason for this. One potential explanation could be an altered nociception, requesting another EA strategy than in non-opioid patients. Purpose and hypothesis This study will explore the frequency of failed EA, defined as EA with insufficient analgesic effect to the extent were replacements of the epidural is needed within the first 5 postoperative days (PODs), testing the hypothesis that failed epidural occurs more frequent in patients with CPS on fixed opioid treatment than in non-opioid patients without CPS.
This is a multicenter prospective study of patients who currently have stably implanted spinal cord simulators. Patients will be randomly assigned to turn on or off their spinal cord stimulators for two week intervals up to six weeks after enrollment, and on the final day of study participation, for one hour intervals, in a multi-crossover design.
The goal of this prospective study is to identify variables that can predict whether an interdisciplinary biopsychosocial intervention for patients with osteoarthritis will be successful. Using an observational design, patients admitted to this program during the 3-year period (2019-2021) will be included and data gathered during routine clinical practice at baseline and end of treatment of patients who gave informed consent, will be used. With these data a prediction model will be build and internal validation with bootstrapping will be done.
Spinal Cord Stimulation Trial to Permanent Prediction is a prospective, longitudinal, multi-center, non-randomized, multi-arm, open-label, clinical feasibility study designed to investigate whether objective data collected from chronic pain patients is predictive of subjective patient-reported outcomes and of adjustments to patient programming parameters.
A 6-week randomized clinical trial (RCT) with a 46-week follow-up compared the effect of Alfredson and Silbernagel eccentric programs for the treatment of AT. The primary outcome was a change in the Victorian Institute of Sport Assessment - Achilles (VISA-A) scale from baseline to 12 months. The study was approved by the Ethics Committee of the Faculty of Physical Education and Sport, Charles University (Project number: 254/2021). All participants provided written informed consent before participation.
There are psychosocial factors that affect pain, and therefore, psychological intervention techniques have been added to its usual pharmacological and physiotherapeutic treatment. Despite the abundant evidence that addresses psychosocial factors as clear mediators in the perception of pain, the use of psychological techniques for pain management in competitive athletes, and more especially in competitive athletes with physical disabilities, is scarce. The purpose of this study was to ascertain the perception of high-level competitive athletes with physical disability and sports agents (coaches, physiotherapists and psychologists).
This qualitative nested sub-study will aim to explore how chronic pain (as defined as pain lasting for more than 3 months) impacts older adults' depression and treatment in a brief psychological therapy of behavioral activation (BA)
The beliefs held by students lead to behaviours in response to their pain which can be both helpful or a hindrance to how they manage their pain. The one-day education event aims to educate the cohort on the contemporary scientific understanding of persistent pain. It is hoped this event will result in an improvement in the alignment of beliefs and behaviours to contemporary understanding of persistent pain. The principal aim is to evaluate the pre-post beliefs about pain following a one-day pain education event.
The aim of this run-in design, feasibility study is to assess outcomes (including opioid-use, pain intensity, emotional function, and general physical function) for an augmented reality illusion therapy in participants with chronic hand joint pain due to arthritis.
