Active clinical trials for "Chronic Pain"

A randomized controlled with cross over study compares efficacy of burst stimulation, 1000 hertz stimulation, and standard stimulation in an non-superiority trial. The study duration is approximately 24 weeks and each stimulation modes will last for approximately 3 weeks with approximately 4 days of wash off in between.

The objective of this project is to estimate the frequency and the characters of the chronic pains by a follow-up which begins during the registration on the waiting list of transplant and which ends at the end of the third year following the lung transplantation. It is a forward-looking study of prevalence entering within the framework of the common care. After lung transplant, pain will be evaluate with questionnaires every day during the hospitalisation, and then after 1 month, 3 months, 6 months, 1 year, 2 years and 3 years.

prospective cohort study of women who underwent caesarean section in mulago hospital. followed up for 2 months and assessed for development of persistent post operative pain at the incision site and its effect on quality of life. incidence of persistent postoperative pain and associated factors determined.

This multicenter randomized (block randomization) controlled parallel arm pilot study comparing the incorporation vs no incorporation of a Nurse Pain Educator into clinics that treat chronic non cancer pain patients with opioid analgesics. Subjects who are either opioid naïve or opioid experienced will be enrolled into the study.

The overall aim of this study is to test the acceptability and feasibility of an interactive, web-based mindfulness training with active duty soldiers being treated for chronic pain.

This project focuses on whether nonspecific factors as well as patient characteristics contribute to treatment outcome differences. The project uses assessment instruments, computerized adaptive tests (CATs), from the Patient-Reported Outcomes Measurement Information System (PROMIS®). The research team has recently developed and tested (using PROMIS methods) a set of instruments to assess non-specific factors in healing from the patient's perspective. These instruments, the Healing Encounters and Attitudes Lists (HEAL) assess the Patient-Provider Connection, Treatment Expectancy, views of the Healthcare Environment, Positive and Negative Attitudes, Spirituality, and Attitude toward Complementary and Alternative Medicine (CAM). HEAL CAT's, like other PROMIS CATs, are brief, easy to use and understand, and are designed to apply to a broad spectrum of treatments and health conditions. In this project, the investigators aim to 1) evaluate whether HEAL predicts chronic pain treatment outcomes, 2) examine heterogeneity of treatment effects based upon HEAL and PROMIS scores in integrative and conventional medicine settings, and 3) interview patients and their clinicians regarding the utility of HEAL, PROMIS and a Pain Log for enhancing communication. The investigators will administer HEAL CATs and other PROMIS CATs (depression, anxiety, sleep disturbance, fatigue and physical function) to 200 patients who are starting treatment for chronic pain in integrative medicine and conventional medicine settings. Follow-up assessments will be completed 2 and 4 months after baseline testing. The investigators will evaluate factors that may predict which patients judge themselves to be improved, the same, or worsened. Some of the possible factors that may contribute to improvement include HEAL scores, emotional distress, or the preference for CAM or conventional treatment. The investigators are also interested in learning whether patients find the assessments to be clear and useful. A subset of 50 patients and approximately 10 clinicians will complete interviews about the HEAL and PROMIS questions, and about the Pain Log developed by a patient advocacy group partner, the American Chronic Pain Association. By interviewing patients and their healthcare providers, the investigators hope to determine the clarity and acceptability of the HEAL and other assessments, and to learn whether HEAL and PROMIS summaries enhance patient-provider communication in the clinical partnership.

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.

A 12-year follow-up of 166 women with fibromyalgia (FM) or chronic widespread pain (CWP) in western Sweden. The 166 women participated in a Randomised Controlled Trial called GAU in 2004-2005, aiming to investigate the effect of pool exercise and patient education. The primary aim of the present study is to examine the change of symptoms after 11-12 years in 166 women with FM or CWP and also investigate predictors of change of symptoms and work ability. The 166 women will be asked to participate in the present follow-up study. The follow-up examination comprises a standardised interview of symptoms and demographic variables, a battery of self-administered questionnaires and tests of physical function.

Chronic pain is devastating both to individuals and society. In an aging population, surgery is an increasing cause of chronic pain, with rates of persistent post-operative pain ranging from 10-65%.In particular, Persistent Post-Mastectomy Pain (PPMP) occurs in roughly one third of women who have had mastectomy. The occurrence of PPMP does not seem to be strongly determined by the type of surgery, chemotherapy, and radiation treatment, suggesting that individual person-specific factors may play a more important role. In fact, recent studies indicate that individual differences in pain sensitivity (psychophysics) are more closely associated with PPMP than surgical/medical variables. Specifically, sensory testing revealed that women who developed PPMP had lower pressure pain thresholds and greater temporal summation of pain stimuli than women who did not develop this chronic pain condition. Moreover, psychosocial factors such as anxiety, depression, catastrophizing, and somatization were more prominent in women with PPMP. These preliminary, retrospective studies suggest that individual psychophysical and psychosocial characteristics could be important risk factors for PPMP. Accordingly, the aim of this study is to comprehensively and prospectively study women having mastectomy surgery, to determine the relationship between pre-operative psychophysical and psychosocial factors and the development of PPMP. Using these data, a prediction model for PPMP will be developed, thus allowing a preoperative calculation of a "PPMP risk score" for any patient facing mastectomy.

Psychologic status is associated with poor outcome after joint arthroplasty and perhaps chronic pain. To enhance the therapeutic effect of a psychologic intervention, the specific disorders or pain-related beliefs that contributed to chronic pain should be identified. We therefore determined whether specific psychologic disorders (depression, anxiety disorder) or health-related beliefs (self-efficacy, pain catastrophizing) are associated with chronic pain after joint arthroplasty for osteoarthritis.
