Active clinical trials for "Low Back Pain"

Ten patients with acute or chronic low back pain will be invited to try a multimodal device for 20 minutes. Pain will be recorded prior to and after use, and feedback on the device will be elicited.

Background: Attention and awareness towards MSDs in the dental profession has increased considerably in recent years. From recent literature reviews, it is learned that prevalence of MSDs in dentists is 64-93%. It has been seen that the use of magnification systems not only improves the operator's visual capabilities, but also allows for a more correct posture, and to prevent the onset of back and neck disorders. Purpose and methods: Evaluate dentist posture during extraction of third lower molars depending on whether the operator uses the naked eye, surgical loupes or surgical microscope systems. Data will be evaluated through the index RULA (rapid upper limb assesment) to define whether there is a change in exposure to the risk of MSDs (Muskoloskeletal disease) and using fiducial markers for the movement analysis of the operator during the procedure.

CONTEXT: Low back pain (LBP) is a common complaint in gymnasts. A deficit in the control of lumbopelvic movement has been related to low back pain. OBJECTIVE: This study aims to examine the effectiveness of an education session about low back motor control during hip extension in the lumbopelvic sagittal movement control of elite gymnasts. DESIGN: single-group, pretest-posttest clinical trial. PARTICIPANTS: 70 Elite Rhythmic Gymnasts INTERVENTION: One standardized theoretical practical session of 15 Min that includes anatomical issues and one practical exercise in quadruped position for controlling the movement of lumbar spine during hip extension and flexion.

Purpose Physical activity reduces the risk of several diseases of the body and the mind1, 2 and can help the elderly maintain physical abilities and self-efficacy in daily life1. The overall purpose of the project is to provide clinicians with a tool to objectively assess physical activity in daily life and thus provide an informed basis for individualized care of elderly patients with spine disease. We would like to introduce this tool to a broad population of elderly patients with low back pain to give an overview of the range and variability in physical activity. We will also look into a method for accurate step count in spine disorders where patients have severe walking impairment due to affected lumbar nerve roots.

Mental imagery has been used in a variety of pathological instances in support to classical therapeutic treatments. The aim of the present study was to observe the effect of internal Kinesthetic and external Visual Imagery to improve proprioceptive feedback in low back pain. Fifty-five subjects with a history of low back pain were included in two experimental groups who used mental imagery and one control group who did not. The results showed the effectiveness of the Internal Kinesthetic Imagery to improve the accuracy of repositioning of lumbo-sacral spine that may subsequently improve the quality of the proprioceptive input. The possibility to use effectively mental imagery, as a part of proprioceptive rehabilitation process, is the principal outcome of this study.

Proprioceptive weighting changes may explain differences in postural control performance. In addition, the respiratory movement has a disturbing effect on postural balance. Postural balance seems to be impaired in individuals with respiratory disorders. Besides the essential role of respiration, the diaphragm may also play an important role in the control of the trunk and postural balance. Deficits in proprioception are found in a subgroup of patients with low back pain. In addition, disorders of respiration have been identified as strongly related to low back pain. The aim of the study is to clarify whether loading of the inspiratory muscles has a negative effect upon proprioceptive postural control in healthy individuals and individuals with recurrent low back pain.

Low back pain (LBP) is considered one of the most common musculoskeletal disorders in modern society, resulting in substantial costs to society. Factors associated with the development of low back pain include poor posture, strenuous work with the body, inadequate non ergonomic work and traumas. Rotation movement pattern of the lumbar spine in different positions is essential aspect in understanding the LBP Pathophysiology. Rotation coupled with forward bending (flexion) is a dominant factor which could increase the risk LBP and disc prolapse. There is also a decline in range of motion (ROM) of rotation in forward bending (flexion) compared to neutral position during sitting and standing. In addition,lumbar rotation movement patterns differ in population with LBP compared to asymptomatic individuals. Healthy individuals exhibit rotation accompanied by consistent coupled movement patterns of lateral bending in the opposite direction at thr upper levels, and by lateral bending in tge same direction at the lower levels . while Chronic LBP patients exhibit non consistent patterns altered from those of the normal population.

This research study is being done to understand the outcomes of back pain treatment and costs associated with it in an academic hospital outpatient setting. The investigators will conduct a prospective observational cohort study to assess the clinical outcomes and utilization of health care services of 175 Osher Clinical Center (OCC) patients with chronic low back pain (CLBP) compared with a comparison group of 175 non-OCC CLBP patients treated within Brigham and Women's Hospital. Outcomes will include assessment of functional status, symptom relief, satisfaction with care, health-related quality of life, and worker productivity, and will be measured in person at baseline, and by phone by an interviewer blinded to cohort group at 3, 6, and 12 months.

Background. Patients with chronic low back pain display hyperexcitability of the central nervous system (central hypersensitivity). Such hypersensitivity may occur in the acute phase and represent a risk factor for the development of chronic pain. Objective. To determine the prognostic value of central hypersensitivity for the development of chronic low back pain. Design. Prospective cohort study. Setting. Primary care. Patients. 140 individuals with acute low back pain and no history of chronic pain. Outcomes. Primary prognostic variable will be the pain tolerance threshold at the second toe (the pressure intensity at which a further increase in pressure is deemed intolerable). Exploratory secondary prognostic variables are measures of mechanisms related to central hypersensitivity: stimulus-specific hypersensitivity (pressure, electrical, heat and cold stimulation); tissue-specific hypersensitivity (skin vs. muscle stimulation); localized vs. widespread hypersensitivity; spinal cord modulation (electrophysiological measures of hypersensitivity and changes in receptive fields); modulation at brain level (descending modulation of nociceptive input and cortical plasticity). Clinical primary outcome will be the occurrence of chronic low back pain at follow-up. Main analysis. The investigators will use least square logistic regression models to determine the association of central hypersensitivity with prognosis. Relevance. An understanding of the prognostic value of central hypersensitivity may allow an early stratification for treatment of individuals at risk of developing chronic low back pain. Subgroups of patients may be selected for clinical trials on novel pharmacological approaches for the prevention and treatment of central hypersensitivity.

The purpose of this observational study is to investigate the impact of fentanyl matrix on improvement of pain and functioning in spinal disorder-related chronic pain.
