Active clinical trials for "Low Back Pain"

INTRODUCTION Pamidronate and other bisphosphonates (bisph) have an anti-nociceptive effect in animals. In humans, IV pamidronate is analgesic in patients affected by numerous painful conditions, including cancer bone pain, complex regional pain syndrome (CRPS), ankylosing spondylitis, and rheumatoid arthritis. The investigators have explored the effect of IV pamidronate in the management of chronic low back pain (CLBP), a worldwide public health problem in terms of lost workdays, treatment costs, and suffering. The study was a randomized, double blind, dose-escalation trial of IV pamidronate. Study participants were divided among four study phases. Each group received IV placebo or escalating doses of IV pamidronate. STUDY DESIGN A phase I-II, randomized, double-blind, placebo controlled, dose finding study for the treatment of patients with CLBP with IV pamidronate. The study was first conducted at Beth Israel Medical Center, NY for the first two groups, and was completed at Mount Sinai Medical Center , NY for the remaining groups. PRIMARY OBJECTIVES The intent of this pilot study was to determine the optimal IV pamidronate treatment protocol for CLBP in a Phase III trial. Primary study aims were safety and average daily pain. Subjects used an electronic diary (LOGPAD) to record their daily adverse events (AEs) and their baseline and post-treatment average pain on the 0-10 numerical rating scale (NRS). STATISTICAL ANALYSES All the analysis were performed on an intention-to-treat basis. Primary outcomes are LOGPAD change in pain severity and whether a patient was a responder (pain score dropped ≥2 points or ≥30%). Because there was no statistical difference in these two outcomes among the 4 placebo groups, all placebo patients were combined (Comb PL) in the subsequent analyses. Primary analytic tool was mixed model for repeated measures (MMRM), assuming autoregressive covariance structure (LOGPAD pain and Brief Pain Inventory - BPI interferences), and Generalized Estimating Equation (GEE) model for categorical outcomes (Response rates and Patient Global Impression of Change - PGIC). The main objective was to assess whether the changes in outcome from baseline or the response rates were the same across the study phases, while adjusting for baseline values and time effect. Least square means were contrasted. Interaction between time and study phases were also tested to see if the treatment effect is a function of time. Fisher's exact tests or ANOVA (Kruskal-Wallis) tests were performed for cross-sectional group comparison, including baseline.

The primary objective of this study is to evaluate the efficacy of hydrocodone bitartrate extended-release tablets at doses of 30 to 90 mg every 12 hours compared with placebo in alleviating moderate to severe pain in patients with chronic low back pain. Patients may be opioid-naïve or opioid-experienced.

This was a clinical effectiveness trial designed to compare the effectiveness, safety, and tolerability of treatment with tapentadol prolonged release with that of oxycodone/naloxone prolonged release in non-opioid pre-treated subjects with severe chronic low back pain with a neuropathic pain component. Both tapentadol and the opioid oxycodone are effective in chronic severe pain and tapentadol and oxycodone/naloxone have shown advantages in gastrointestinal tolerability versus oxycodone. Therefore, it was of high scientific interest to compare the latter 2 analgesics with respect to gastrointestinal tolerability. Tapentadol may have advantages regarding the neuropathic pain-related symptoms of low back pain due to its 2 mechanisms of action.

The purpose of this study is to analyze the effectiveness of a three manipulative therapy techniques in People with Chronic Low Back Pain.

Aim of the study Failed back surgery syndrome (FBSS) is a clinical entity consisting of chronic leg and /or back pain due to radicular nerve damage. The effectiveness of Spinal Cord Stimulation (SCS) in the pain management of patients with FBSS is proven. Patients mostly have dominant leg pain, however a significant percentage of FBSS patients has a more pronounced back pain and are commonly excluded from SCS as it is often inadequate in relieving both the back and leg pain components. Recently some reports showed the benefit of subcutaneous stimulation (SubQ) for low back pain in patients with FBSS. This has been confirmed by a feasibility study performed by our group. The aim of the randomized controlled study is to evaluate the effect of SubQ on low back pain in FBSS patients for whom SCS gives an inadequate back pain relief. Hypothesis We hypothesize that SubQ in addition to SCS in FBSS patients with leg and low back pain is more effective in treating low back pain (i.e. >50% pain reduction) than SCS alone.

Chronic low back pain (CLBP) is one of the most common, costly and disabling conditions. It is often refractory to treatment, with patients requiring long-term opioid therapy. Mindfulness meditation is a promising treatment for chronic pain, mental health and addictive disorders. When combined with cognitive behavioral therapy (CBT), a standard of care for CLBP, it may produce additive benefits. The goal of this randomized controlled trial (RCT) is to evaluate the feasibility and efficacy of an innovative behavioral intervention to improve the health of adults with opioid-treated CLBP. This RCT will test the hypotheses that, at 26 weeks, meditation-CBT group participants (meditation-CBT + usual care), compared to those in a wait-list control group (usual care alone), will improve health-related quality of life (primary outcomes: pain severity and physical function) and reduce opioid medication use (secondary outcome). In addition, they will also decrease alcohol and drug use/misuse, and improve stress-sensitive measures and economic outcomes.

A 12-week randomized controlled trial (RCT) for chronic low back pain in predominantly minority populations comparing yoga classes once/week vs. twice/week. Primary outcomes are pain intensity and measure of disability; secondary outcomes are pain medication use, treatment adherence, and health-related quality of life.

Patients will be randomized to receive open-label (honestly described placebo) immediately at baseline or be eligible to receive the open-label treatment three weeks after the baseline measurements. Therefore all patients will be eligible to receive open-label placebo treatment for their chronic low back pain during the course of the study.

The purpose of this study is to investigate the effects of a treatment involving the application of lidocaine injected on the low back area for pain control. The study will compare this form of treatment with other options such as physical exercises or pain killer medication, different measurements are going to be used to quantify the response to each of these treatments.

Nowadays, the research priority in low back pain area have been find subgroup of patients with the same characteristics that might achieve better outcomes in a specific intervention. However, even though the studies in this area have increased, questions of this nature remaining without an adequate answer, or with limited evidence. Therefore, the investigators propose to examine the ability of clinical tests, developed to assess alterations related to clinical lumbar instability, to identify subgroups of patients with non specific chronic low back pain that may have better outcomes after a motor control exercises intervention.
