Active clinical trials for "Low Back Pain"

Foot disorders have been recognized as being linked to chronic low back pain

In general , the diagnosis of back pain can be broken into three major categories: Mechanical ( Osteoarthritis , Spinal stenosis , Spondylolisthesis) ; Non- mechanical ( Tumor , Infection , Inflammatory arthritis ) and Miscellaneous (Osteoporosis , Psychosomatic disorders , neuropathic joints , visceral diseases ). Although 98% of LBP may be caused by mechanical factors, it is the other 2% caused by malignancy, infection, visceral diseases and other red herrings that must be considered most seriously. The investigators have observed in their practice that lateral pressure on 5th lumbar vertebra sometimes gives rise to cervicothoracic pain and central PA pressure over cervicothoracic spines reproduce original low back and leg pain. So the question arises whether Cervico-thoracic dysfunction is associated with low back pain with or without radiation to lower extremities?

The aims of this study are to investigate whether pelvic pain and low back pain disability are associated with postpartum depression and to compare the prevalence between women without Low back pain and disability and women with Low Back Pain (LBP) and disability every trimester, and correlate postpartum Depression and some clinical and biopsychosocial variables: subgroups of LBP, disability, pain intensity, pain widespread and nationality, in a cohort of Spanish women at 2 months postpartum.

The purpose of this study was to evaluate feed-forward contraction of the transversus abdominis and thickness of the transversus abdominis, obliquus internus, and obliquus externus during calm and standardized respiration in low back pain patients and pain-free subjects.

The purpose of this study is to determine the prevalence of lumbar facet joint pain detected by manual segmental provocation tests the prevalence of MRI findings of the lumbar facet joints (hypertrophy, effusion, edema) the association of lumbar facet joint pain and MRI findings on a segmental level in subjects with current low back pain and in a control group.

A randomized, open label, single-dose, 6-sequence, 3-period, crossover study to evaluate a pharmacokinetic drug interaction between eperisone hydrochloride and aceclofenac in healthy male subjects.

There is evidence for altered muscle activity patterns in individuals with non-specific chronic back pain (NSCBP). It is unknown why these alterations in activation pattern occur and how they may be linked to pain experience and to the development of CNSBP. The main objective of this study is to investigate the spatial aspects of muscle activation in relation to fatigue/endurance and CNSBP. A novel approach, utilizing a new multi-channel surface-EMG (MCsEMG) technique will be applied in this project to get insight in fundamental mechanisms related to motor control and fatigue/endurance. In this project data from healthy persons and from patients with NSCBP will be collected and analyzed. NSCBP patients will be compared to healthy persons. To minimize heterogeneity between groups the subject's age range will be from 30 - 50 years. The investigators main hypothesis is that motor control mechanisms of the lumbar muscles are disturbed in NSCBP patients compared to normals, explaining the reduced tolerance for static postures. There has been little investigation of the lumbar musculature with MCsEMG recordings. The lumbar musculature has a complex organization; many, relatively small muscles, in a restricted area. Utilizing two HDsEMG grids with 252 Ag/AgCl contacts will be the superior non-invasive method to investigate motor control mechanisms in this region, and further the investigators understanding of neuromuscular adaptations related to NSCBP. The project may demonstrate changes that will lead us to new insight and new strategies for the treatment of back pain.

The purpose of this study is to verify the existence of neuromuscular neutral zones(NNZs) in humans, and develop non-invasive techniques to measure intervertebral kinematics of the lumbar spine. The results will be used to accurately quantify NNZs in humans, and provide a foundation for clinical trials on low back pain patients using this methodology.

A prospective study to assess the association between the change in quality of sleep and the change in intensity of pain in Spanish patients seen for subacute or chronic low back pain. The objective is to determine the prevalence of sleep alterations, the association between quality of sleep and intensity of pain, degree of disability, intensity of catastrophizing and depression.

To assess: a) The prevalence of Modic changes and other findings on lumbar magnetic resonance imaging (MRI), among Spanish adult chronic LBP patients, b) Patient characteristics and radiological findings associated with Modic changes.
