Active clinical trials for "Low Back Pain"

Introduction. Nonspecific low back pain (NSLBP) is a very prevalent medical condition, especially in subjects with chronic obstructive pulmonary disease (COPD). The diaphragm is a respiratory muscle, but it takes part in trunk stabilization on lumbar spine. NSLBP is related to lack of spinal control. The COPD symptoms include lack of efficiency in diaphragm, which could be connected to NSLBP. Hypothesis and objectives. COPD can contribute to NSLBP. It is associated with diaphragm weakness, severity of respiratory function, lower level of physical activity and quality of life in COPD. Methods. A descriptive observational cross-sectional study was conducted with two groups: the first one with subjects with COPD and the second one with subjects without it. Data were collected on: pulmonary function; respiratory muscles strength; trunk postural control; quality of life with COPD; physical activity level; lumbar pain presence, intensity and disability. Data were collected in a single session.

The first propose of the study is to understand the contraction of deep and superficial multifidus in patients with non-specific low back pain and the elderly. The second purpose of the study is to understand the relationship between the multifidus and the functional performance in patients with non-specific low back pain and the elderly. The hypothesis is that the patients with non-specific low back pain and the elderly have less ability to contract the deep multifidus then asymptomatic adults and younger adults. Besides, the multifidus is correlated to the functional performance.

The aim of the study is to compare the neutrophils to lymphocytes ratio (NLR), platelets to lymphocytes ratio (PLR), eosinophils to lymphocytes ratio (ELR), red blood cell distribution width (RDW), mean platelet volume (MPV), systemic immune inflammation index (SII), erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) which are the hematological parameters associated with systemic inflammation in acute and subacute/chronic low back pain. Secondary purpose; evaluation of the prognostic roles of hematological parameters associated with systemic inflammation in low back pain in predicting chronicity.This study is a retrospective case-control study. The data of patients who applied to the emergency department with the complaint of acute (less than 4 weeks) low back pain or to the Physical Medicine and Rehabilitation outpatient clinic with the complaint of subacute (lasting 4-12 weeks) or chronic (longer than 12 weeks) non-specific low back pain in the last 3 years will be scanned. The data of patients who applied with complaints other than medical conditions known to be associated with painful conditions and/or inflammatory response will be screened as a control group. The data of patients between the ages of 18-65 will be included in the study. In conclusion, the data of 150 patients who presented with acute non-specific low back pain, 150 patients who presented with subacute/chronic non-specific low back pain and 150 participants as the control group will be included in the study for use in analysis. Participants' age, gender, duration of low back pain (days), if evaluated, conditions associated with low back pain in cases with subacute/chronic pain, ESR, CRP, RDW, MPV, neutrophil count, lymphocyte count, eosinophil count and platelet count in blood tests at admission examinations will be recorded. NLR will be calculated by dividing the number of neutrophils by the number of lymphocytes, PLR by dividing the number of platelets by the number of lymphocytes, ELR by dividing the number of eosinophils by the number of lymphocytes, and SII by the formula "platelet numberxneutrophil number/lymphocyte number".

Lumbar spinal fusion was introduced approximately 70 years ago and has evolved as a treatment option for symptomatic spinal instability, spinal stenosis, spondylolisthesis, and degenerative scoliosis. Many techniques evolved since then, from wiring, rods, pedicle screws, and recently inter-spinous fixation devices like the Aspen. Along its evolutionary trail, various methods for achieving circumferential fusion have arisen. Distinct from staged anterior/posterior fusion techniques, two methods of achieving an interbody fusion from a posterior approach have emerged: posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF). Recently, the lateral approach for interbody fusion (XLIF) has became a more common technique, requiring in some cases, complemental posterior fixation with pedicle screws, facet screws or interspinous fixation devices like the Aspen device. In this study, we address the clinical and radiological outcome of a novel technique using standard PLIF interbody fusion and insertion of the Aspen device via posterior lumbar approach.

The purpose of the study is to validate in Mexico a spanish translation of the 2.1a Oswestry Disability Index (ODI) version in patients with low back pain. Internal consistency, reproducibility and reliability will be addressed scoring the results of the translated version at two time frames. A previously spanish validated translation of the of the Roland Morris Disability Questionnaire (RMDQ) will be used to compare and evaluate both versions.

This is a control-case study. It has been designed to determine if there is a relationship between the cross sectional (thickness), through RUSI ultrasound, of the abdominal muscles, lumbar and hip muscles with the results of the functional tests, to determine its relevance in patients with low back pain and / or ciatalgia and lumbar disc herniation in non-professional athletes. The secondary objectives of the study will be to know if there is a relationship between the results of ultrasound measurements and functional tests with the result of the disability questionnaires, the amount of pain and its location, as well as determine the relevance, depending on the results of ultrasound measurements and test of the presence or not of a lumbar disc herniation.

To delineate the underlying mechanisms that contribute to chronic low back pain, by extending our knowledge on structural characteristics of the lumbar multifidus muscle using ultrasound muscle imaging, and by examining the association of structural features with functional performance, more precisely proprioceptive control.

The objective is to compare the accuracy and reproducibility of measurements taken with electronic calipers and conventional calipers. Using both calipers, reproducibility will be determined by comparing results from a number of practitioners and accuracy will be determined by comparing results with those obtained from X-rays.

This prospective, longitudinal study aims to identify modifiable predictors of return to work after back surgery.

Low back pain is a common health issue in elderly population. According to the statistics, more than 80% of Taiwanese suffer low back pain in the life. The cause of low back pain includes lumbar spondylosis, osteoporosis, compression fracture, muscle strain, spondylolisthesis…etc. In addition to drugs and surgery, physical therapy is an alternative choice for conservative treatment. Therefore, in this study, the investigators propose to analyze the physical examination, diagnostic methods, X ray, physical therapy records, physical therapy methods and clinical outcomes in patients with the diagnosis including lumbar spondylosis, low back pain, osteoporosis, compression fracture, back pain treated at National Taiwan University Hospital and received rehabilitation at the Physical Therapy Center in recent ten years.
