Active clinical trials for "Back Pain"

Objective: The objective of this study is to compare the efficacy of duloxetine in the treatment of patients with chronic low back pain with a radicular component to placebo. Study hypothesis: Duloxetine is a new substance now in use for the treatment of neuropathic pain. It has proven its efficacy in diabetic peripheral neuropathy and fibromyalgia in several trials. The investigators therefore hypothesize that duloxetine will be efficacious in patients with chronic low back pain and a radicular component. Study Rationale: Chronic low back pain is an extremely common diagnosis. However, therapeutic options for the condition are limited and therapy remains difficult. Duloxetine has proven its efficacy in patients with neuropathic pain and may also be useful in chronic low back pain. If the investigators are able to show a benefit for patients in the duloxetine arm, the substance may constitute a further treatment alternative in chronic low back pain. Study Design: Prospective, randomized, double-blind placebo-controlled cross over study. Patients will be administered duloxetine for 4 weeks followed by a 2 week wash-out phase after which they will be medicated with placebo for 4 weeks. A second group of patients will receive the medication in reversed order. The primary study endpoint is constituted the weekly mean of VAS-Score in the last week of each treatment period. Secondary endpoints are defined as use of rescue medication, Beck Depression Inventory score, Health related Quality of Life SF-36 score and side effects/adverse events.

The purpose of this study was to compare the efficacy of three exercise programs in patients with chronic low back pain: Segmental stabilization, superficial strengthening and stretching. Groups were contrasted regarding pain, functional disability and TrA muscle activation capacity. The three groups of exercise improved pain and functional disabilities, and the Segmental stabilization group was better in the ability to recruit TrA muscle.

The purpose of this study is to examine 4 different epidural dosing regimes of local anaesthetic solution in a series of 3 epidural injections over a period of 12 months to determine the optimum dose of anaesthetic solution for pain relief and to determine the nature of any adverse events by measuring anxiety and depression, functionality and any side effects of the medication.

The primary purpose of this proposal is to conduct a prospective, randomized, controlled clinical trial to examine whether or not treatment based on a person's direction-specific, impairment-based LBP classification is more effective than Non-specific treatment in improving short- (6 weeks) and long-term (6 and 12 months) outcomes in people with chronic LBP. We hypothesize that treatment based on a person's direction-specific, impairment-based LBP classification (Classification-specific) will result in better outcomes than Non-specific treatment. Our approach to classification-directed treatment is based on the proposal that a person's LBP is the result of adopting direction-specific strategies of movement and alignment of the spine which then are used repeatedly during the person's everyday activities. The exposure of spine tissue to repeated loading in the same direction across a day is proposed to accelerate the accumulation of stress, microtrauma, and eventually LBP. We also hypothesize that until the factors contributing to the use of the direction-specific strategies of the spine are modified, the LBP problem will persist or recur. Identification of homogeneous subgroups of people with LBP will enhance 1) the power of clinical trials, 2) prognosis, and 3) the ability to identify mechanisms contributing to different LBP problems.

A multi-center placebo controlled, double-blind, trial comparing the analgesic efficacy and safety of Acetram Contramid® BID versus placebo for the treatment of acute low back pain in patients between 18 and 80 yrs of age.

The purpose of this study is to compare the levels of Substance P in saliva, in patients with severe chronic low back pain and in subjects without it. In addition, to explore a possible cutoff point, in order to define normal and pathological levels of Substance P in saliva. The ultimate objective would be to design a measurement method for use in routine clinical practice.

The primary purpose of the study is to test the efficacy of 2 tablets (twice daily) of ABT-712, compared to placebo, administered over a 4-week period in participants with moderate to severe mechanical chronic low back pain (CLBP).

The research objective is to determine which physical therapy (PT) treatment is the most efficacious for patients with lower back pain (LBP), who have been subgrouped based on certain clinical features. There is only limited evidence that supports any one PT treatment for patients with LBP since PT treatment outcomes for exercise protocols are equivocal, given the heterogeneous clinical features of patients with LBP. Thus, classification of patients with LBP into subgroups with shared clinical features has been identified as a research priority by several groups in order to prescribe the most efficacious PT treatment for each homogeneous subgroup. The investigators hypothesize that particular PT treatments are most efficacious when applied to patients with LBP, who present with particular clinical and neuromuscular features.

Some physicians, physiotherapists and nurses use or even suggest unstable shoes in cases of low back pain. No studies on the real effects of these shoes on low back pain in health care professions have been carried out and therefore as yet there is no real evidence of their effectiveness. Thus the investigators assume that wearing unstable shoes over a period of six weeks could reduce low back pain and functional disability due to the changes of the gait and posture and may increase the quality of life. The purposes of this study are: To evaluate the modifications of pain level, functional capacity and quality of life among individuals with moderate level of non-specific chronic low back pain after wearing unstable shoes. To quantify biomechanical modifications of gait and posture.

Isostretching is effective in treating chronic back pain to improve pain, quality of life and functional capacity.
