Active clinical trials for "Chronic Pain"

Groin hernia repair is a common procedure performed in approximately 2,000 patients per one million inhabitants. Severe chronic pain following groin hernia repair is seen in 2-5% of the patients indicating that a large number of patients each year suffer from debilitating reduction in health-related quality of life. This study examines the effect of ultra-sound guided blocks with local anesthesia in the groin in regard to pain relief and sleep quality. The hypothesis of the study is that a block will confer significant pain relief to patients with severe chronic pain following open groin hernia repair.

The purpose of this study is to determine whether Integrative Medicine Group Visits (IMGV) are effective for treating patients with chronic pain and depression.

Low dose tricyclic antidepressant drugs are routinely administered co-analgesics in pain medicine. Amitriptyline is largely considered as a gold standard. Amitriptyline underlies cytochrome CYP2D6 and CYP2D19 metabolism. CYP2D6 is highly polymorphic; numerous genetic variants result in 4 major classes characterizing enzymatic activity: poor metabolizers, intermediate metabolizers, extensive metabolizers and ultrarapid metabolizers. It is not known to which extent metabolizer classes determine pain outcomes or side-effects. As only one in three pain patients is considered to be a responder to amitriptyline's co-analgesic effect, prediction of treatment efficacy with a fast and easy to perform bedside test may contribute to the patients quality of life. The aim of this study is to determine the influence of cytochrome variants on experimental pain, drug related side-effects and finally identification of active metabolites.

The purpose of this study is to assess the effectiveness of the Stimwave Spinal Cord Stimulator (SCS) System for treatment of chronic pain

The primary objective of this clinical trial is to determine if treatment with an anti-inflammatory drug (delayed-release prednisone) improves the health-related quality of life (HRQOL) of veterans with Gulf War Illness (GWI). The primary outcome measure is a change from baseline of HRQOL with respect to physical functioning and symptoms. Secondary outcomes measures include changes from baseline levels of GWI-associated biomarkers of inflammation in peripheral blood, GWI-associated symptoms (chronic pain, fatigue, and cognitive impairment), and HRQOL with respect to mental functioning.

To determine the effects of varying spinal cord stimulation programming parameters, including stimulation rate, on pain intensity.

The primary objective of this study is to evaluate the analgesic efficacy of 2 dose levels of V116517 versus placebo.

The purpose of this study is to evaluate the safety and efficacy of GRT6005 compared to placebo in patients with moderate to severe chronic pain due to osteoarthritis (OA) of the knee. This study includes a maximum 21 day Screening Period followed by a 15-week Double-blind Treatment Period and a 4-7 day Safety Follow-up period. Patients who are eligible for the Double-blind Treatment Period will be randomized to one of following treatment groups: GRT6005 high-dose range (400, 600 or 800 mcg), GRT6005 low-dose range (200, 300 or 400 mcg), oxycodone controlled release (CR) dose range (10, 20, 30, 40 or 50 mg) or placebo.

Back School (BS) is a behavioural intervention designed to treat and prevent chronic low back pain. Up to date clinical research studies have shown that transcranial direct current stimulation (tDCS) is able to decrease the intensity and duration of pain modulating the activity of brain areas involved in the circuits that regulate pain and facilitating the mechanisms inhibitors descendants of pain control. The aim of this study is to test the feasibility of combining tDCS with a behavioural intervention (i.e. BS) in subjects with chronic low back pain.

Chronic pain is a significant problem for many Veterans, including new Veterans returning from Iraq and Afghanistan. It is also associated with a number of other significant problems, such as post-traumatic stress disorder and sleep problems. All of these can have significant negative effects of the quality of life of Veterans Three different types of treatment that have been used to treat chronic pain in the general population include self-hypnosis, education about chronic pain, and teaching individuals how to be more mindful. The purpose of this study is to see if these three treatments can help decrease pain in Veterans. Additionally, the researchers want to determine if each of these treatments can help reduce the negative consequences associated with pain, such as changes in mood, sleep, and enjoyment of life. Different types of treatment that include self-hypnosis, education about chronic pain, and learning skills on how to change how a person perceives his/her pain have been used to treat chronic pain the general population. The purpose of this study of this study is to see if these different treatments can help decrease pain and improve quality of life in Veterans with chronic pain, and determine how and why these treatments are effective. A subject must have a Veteran status, have chronic pain, speak English and be at least 18 years old to participate. Sleep Sub-Study Chronic pain and sleep problems are common among Veterans. Study researchers believe the treatment interventions provided as part of the main study will help improve pain and sleep. However, the main study does not include a "real time" measurement of sleep nor does it include any specific strategies for examining the relationship between sleep and pain. Previous research has shown that adequate sleep has been linked to improvements in pain reports. Adversely, sleep deprivation has been found to increase pain perception since it decreases a person's ability to disengage from pain. Therefore, the purpose of this sub-study is to measure sleep in order to learn more about how it interacts with chronic pain. All of the subjects in this sub-study will be Veterans recruited from VA Puget Sound who experience moderate-to-severe chronic pain on a regular basis and who have enrolled in the main study. Study investigators will enroll up to 135 subjects into the sub-study.
