Active clinical trials for "Chronic Pain"

The purpose of this study is to determine if creation of a skin wheel with bacteriostatic normal saline, which includes 0.9% benzyl alcohol, is less painful and provides a similar level of anesthesia compared to 1% lidocaine. Participants will receive both types of anesthesia, in random order.

The development of chronic pain is one of the most seen sequelae in the cancer survivor population. Literature reports the presence of pain in approximately 40% of 5-year survivors. Specifically, in breast cancer survivors, chronic pain is estimated to be present in at least 50% of this population. On the other hand, chronic low back pain is one of the leading causes of disability and decrease in quality of life. It has huge economical, psychological and social impacts on individuals, society and health institutions. Unhealthy dietary behavior is associated with the occurrence, maintenance and management of chronic pain. Also, excessive calorie intake and diets rich in sugar, fat, sodium and caffeine were observed in patients having chronic pain. However, although nutritional factors are suggested as an associated lifestyle factor of chronic pain, limited attention is given to dietary and nutritional factors in relation to chronic pain. One particular mechanism drawing attention in the link between nutrition and pain are blood glucose levels and the glycemic response. Animal research shows the potential for reduced blood glucose to influence several pathways involved in chronic pain, including decreased oxidative stress, and reduced neuronal excitability. Given the link between blood glucose levels, as well as the evidence for the importance of interpersonal variability in the glycemic response, this glycemic response can also be of interest for chronic pain research. Finding a possible link between both the glycemic response and pain-related outcomes, could give direction to further research focussing on implementing (personalized) nutritional/dietary advise to maintain healthy blood glucose levels in people suffering from chronic pain. Therefore, this study will provide the first step in this promising line of research, by being the first to look for differences in glycemic response between breast cancer survivors having chronic pain and healthy pain-free controls, and between chronic low back pain patients and healthy pain-free controls. Secondly, this study will also investigate possible associations between glycemic response, pain-related outcomes, nutrition related outcomes, physical activity, and body composition for breast cancer survivors and chronic low back pain patients separately in comparison with healthy pain-free controls.

This study is being conducted to compare intrathecal morphine using the commercially available intrathecal drug delivery systems (IDDS), and conventional medical management (CMM) in subjects with non-cancer, refractory chronic pain.

Some fibromyalgia patients may use inappropriate emotional regulation strategies to respond to pain. Rumination could be one of this inefficient regulation strategies. The investigators believe that the use of rumination strategies to respond to the discomfort of daily physical activity would maintain and aggravate a negative emotional state after the effort. Distraction would be a more effective strategy to cope with pain. From this data, the investigators want to explore the causal link between rumination and negative affectivity after physical activity in fibromyalgia using an experimental design.

This study evaluates the postoperative analgesic effects of transversalis fascia plane block and anterior quadratus lumborum block in patients having cesarean section under general anesthesia. General anesthesia will be performed to all patients for the surgery.

A single-blinded, parallel-group randomized controlled trial was conducted at the national institute of rehabilitation medicine, Pakistan, from April to July 2016, on 30 females who were recruited through non-probability convenient sampling technique and randomly allocated to the experimental and control group.

Based on a mixed-methods design, the objective of this trial is to assess the feasibility and acceptability of the "Agir pour moi" program, an 8-week online self-management program for chronic non-cancer pain (CNCP). The investigators will also explore its potential effects on self-efficacy, pain interference, pain severity, anxiety, depression, catastrophizing, and global impression of change in adults with CNCP awaiting services from a chronic pain multidisciplinary treatment center.

Fibromyalgia syndrome (FMS) is a chronic musculoskeletal condition characterized by widespread pain and tenderness, and often accompanied by impaired physical functioning, depressed mood, as well as deficits in positive affect (PA).Standard behavioral therapies typically focus on minimizing negative thoughts and emotions associated with pain and yield only modest treatment effects. Efforts are therefore needed to develop more effective psychological treatments for chronic pain by identifying new targets for intervention. The objectives of this Stage I randomized pilot trial are to evaluate the feasibility, acceptability, and the impact of a previously developed online positive affect (PA) skills intervention -LARKSPUR (Lessons in Affect Regulation to Keep Stress and Pain UndeR control)-in a sample of Hispanic, non-Hispanic other, and non-Hispanic African American patients with fibromyalgia syndrome (FMS).

Chronic pain is the leading cause of disability worldwide affecting just under 28 million people in the UK. Chronic pain conditions require a biopsychosocial rather than a biomedical model of care. Biomedical management lacks evidence of effectiveness but also has the potential to exacerbate the condition by raising fears and anxiety about potential pathological abnormalities. Healthcare professionals often hold negative beliefs about people with chronic pain and view the condition within a biomedical framework. These negative attitudes can be observed at the pre-registration training stage of the health professionals' career. Thus, the pre-registration phase is an important point where an individual's understanding of, and beliefs about, pain and people with pain may be shaped for the future. The need for improved and better education of healthcare professionals to support best practice for low back pain with the aim of integrating professionals' management of low back pain and fostering innovation in practice is well recognised. This study seeks to quantify the benefits of pain education in knowledge, attitudes and beliefs. The findings may encourage other pre-registration institutions to deliver pain education in a more directed way and simultaneously support the International Association for the Study of Pain's (IASP) proposed integration pain education into existing curriculum.

Musculoskeletal pain has become in a major problem related to its prevalence, treatment cost, absenteeism, quality of life impairment, disability and drugs consumption. The difficulty in musculoskeletal pain control ends in the abuse of drugs by these patients, including opioids. This drugs consumption has become a health problem in the United States and around the world related to their increasing abuse mainly between 2002 and 2011 and has had an impact in the numbers of deaths caused by opioids prescription (reaching 16,651 deaths in United States in 2010). Pain is clearly associated with sleep disturbances (50-80% of these patients suffer from a sleep problem), and in turn poor sleep quality leads to increased pain sensitivity. There is evidence showing that improving sleep disturbance co-occurring pain would improve, and some may reduce the use of opioids in specific patients on long-term opioid therapy. In spite of this reciprocal relationship between sleep and pain only few programs take into account the management of sleep disorders as a non-pharmacological measure for pain control. The hypothesis is: "to address sleep and circadian disorders (SCD) using a Sleep and Circadian Intervention Program (SCIP) in patients treated with rehabilitation by chronic musculoskeletal pain (CMP) optimizes the rehabilitation outcomes and reduces opioids consumption". Main goal: The aim of this PILOT study is to evaluate the feasibility of the protocol of the present study that aims to assess the improvement in rehabilitation outcomes and decrease in opioid consumption, through the management of sleep disorders. Methodology Using a randomised (1:1) controlled feasibility study, 50 men and women will be included to evaluate methodology and identify the potential outcome of the main project. Subjects older than 18 years included in a rehabilitation program by musculoskeletal lumbar pain lasting more than three months will be recruited. Basal Visit (BV): After the signature of informed consent, a medical history, physical exam, evaluation of the pain perception (EQ5D5L), quality of life evaluation (SF36 and FOSQ), mood and anxiety (HADS y PASS20), circadian rhythm study and drugs consumption will be evaluated in both groups. Patients will be randomized to control group (usual rehabilitation program) or intervention group (usual rehabilitation program + sleep circadian intervention program-SCIP). The patient in the SCIP program will received the next intervention: 1) Educational and circadian rhythm intervention: general sleep hygiene recommendation and promotion of daily physical activity. 2) Sleep studies for sleep quality and sleep disorders diagnosis: full polysomnography 3) Sleep questionnaires for another sleep disorders. Based on the results of the studies, patients will be treated according to current guidelines for the management of sleep disorders. 6 month after the SCIP starts patients will be evaluated in the End of Study Visit (EOS) as in the BV and also in their functional improvement and health resources consumption.
