Active clinical trials for "Back Pain"

People with anatomical leg length discrepancy (LLD) commonly presented excessive subtalar pronation of the long leg compared to their short leg in order to equalize leg length. Although such compensation may decrease the stress in the pelvis and/or low back region, the pronated foot may lead to excessive stress loading onto the ankle or foot, resulting in musculoskeletal injuries. Clinically, the pronated foot has been effectively controlled using functional orthoses with proper posting by adjusting the subtalar joint in the neutral position. But for people with compensatory pronated foot resulted from anatomical LLD, to control excessive pronation of the long leg would exaggerate their asymmetry in leg length. Instead, the pronated foot can be controlled simply by adjusting the length of the short leg. However, there is limited evidence of such intervention in previous literature. The purpose of this research project is going to determine the effect of leg length adjustment on pronation control in people with anatomical LLD. According to this purpose, 5 study objectives will be developed: 1) to examine the validity and reliability of LLD measurement using a hand-held laser distance meter, 2) to compare the foot types before and after leg length adjustment, 3) to compare the kinetic variables before and after leg length adjustment during quiet stance, 4) to compare the kinetic variables before and after leg length adjustment during level walking, and 5) to compare symptoms and functional levels related to low back pain (LBP) before and after leg length adjustment. The present research project will be designed as a convenience sampling, prospective, quasi-experimental, and pretest/posttest design. There will be 2 parts in this research: 1) validity and reliability test of laser measure for leg length and 2) foot morphology and kinetic analysis before and after leg length adjustment. For the first part of this research, 10 male adults and 20 adults will be recruited for the validity and reliability tests respectively. Anthropometric measurements, including body height, body weight, foot length, foot width, and heel-ball distance, will be measured after a consent form is signed. Participants of the validity test will receive standing pelvic radiography and laser measure to measure their leg length. Each participant of the reliability test will receive 2 sessions of laser measure using a hand-held laser-distance meter. For the first session, all laser measurements will be employed twice by 2 raters with a rest interval of more than 5 min. One week later, another session of laser measure will be given again by one of these 2 raters. Intraclass correlation coefficient (ICC) will be used to test the interrater reliability, intrarater reliability, and validity of the laser measure method. Standard error of measurement (SEM), and small real difference (SRD) will be calculated to represented intrarater reliability also. For the second part of the research, another thirty adults with compensatory pronated foot resulted from LLD will be included in the research project but the sample size will be adjusted to the appropriate number according to power analysis. Each participant will be asked to fill out the visual analog scale (VAS) and the Oswestry Disability Index (ODI) and receive tests containing foot type examination, quiet stance with eye opening, quiet stance with eye closed, and level walking. All tests will be performed before and after leg length adjustment. The experiment will be completed after collecting 3 successful trials for each test. All procedures will be done one month later. ANOVA with repeated measures will be calculated to compare the differences in these variables among before, immediately after, and 1 month following leg length adjustment when the data fit the assumptions of normal distribution. Discrete variables or variables with non-normal distribution were tested using the Friedman test. All statistical analyses will be calculated using SAS 9.1.3. The significant level was set at α = 0.05 while the power was at 0.8. Five possible results may be expected from conducting this research project: 1) there will be good validity and reliability of the laser distance meter to measure LLD, 2) there will be significant differences in measurements of foot type before and after leg length adjustment, 3) there will be significant differences in kinetic data during quiet stance before and after leg length adjustment, 4) there will be significant differences in kinetic data during level walking before and after leg length adjustment, and 5) symptom and functional level related to LBP will improve after leg length adjustment. Completion of this research project will be projected to provide solid and objective evidences for leg length adjustment through views of morphology and kinetics in people with pronated foot due to anatomical LLD.

The purpose of this study is to compare the effects of a balance reeducation protocol and an evidenced based protocol on pain, function and postural control of low back pain patients.

The purpose of this study is to determine whether buprenorphine hydrochloride (HCl) buccal film is effective and safe in the treatment of chronic low back pain (CLBP).

Modic changes are associated with low back pain (LBP) both in clinical and general population-based samples. Type I changes are regarded as more likely to be painful than type II changes. Several studies suggest that type I changes are inflammatory in nature.

Acute low back pain is a common disorder in general practice. Some general practitioners (GPs) treat acute low back pain (LBP) with acupuncture, despite lacking evidence of its effectiveness for this condition. The aim of this study is to evaluate whether a single treatment-session with acupuncture can reduce time to recovery when applied in addition to standard LBP-treatment according to the Norwegian national guidelines. Analyses of prognostic factors for recovery and cost-effectiveness will also be carried out. The investigators hypotheses are: Acupuncture treatment contributes to faster pain-recovery in acute LBP compared to standard treatment in general practice provided in accordance with the Norwegian national guidelines. Acupuncture treatment for acute LBP improves function, and reduces drug use and sick leave, compared to the standard treatment in general practice provided in accordance with national guidelines. Acupuncture treatment for acute LBP is a cost-effective treatment in general practice. The investigators intend to include a total of 270 patients, 135 in the intervention group and 135 in the control group. The investigators planned to do an interim analysis when reaching inclusion of 150 patients. However, this might lead to reduced overall significance level, and as a result of slow inclusion rate (by December 2015), the investigators plan to extend the inclusion time with one year and then complete the study in March 2017.

The purpose of this study is to evaluate the non-inferiority of the clinical efficacy of two different drugs in the treatment of patients diagnosed with moderate to severe back pain.

The purpose of this study is to evaluate the non-inferiority clinical efficacy of two different drugs in the treatment of patients diagnosed with moderate to severe back pain treatment.

The primary objective is to demonstrate the safety and tolerability of COV795 with up to 35 days use as evaluated by physical exam, vital signs, pulse oximetry, clinical laboratory tests, and other adverse events (AEs).

Explore the clinical efficacy of 7-day treatment regimens of guaifenesin in order to investigate the evidence that guaifenesin is an effective treatment for upper back/neck/shoulder muscle spasm/stiffness and pain.

Opioids are frequently prescribed for chronic low back pain (CLBP). Psychiatric illness, such as high levels of depression and anxiety symptoms, is a common co-occurrence in chronic pain patients (and is termed comorbid negative affect [NA]). The purpose of the study is to determine whether CLBP patients with either a high vs. a low or moderate degree of NA have different pain relief responses to oral opioids.
