Active clinical trials for "Low Back Pain"

Lumbar spine bone marrow is well explored in Magnetic Resonance Imaging (MRI) but some bone marrow diseases are hard to analyze with this method. Furthermore, there is heterogeneity in normal bone marrow, called apparent diffusion coefficient (ADC). Histological and technical factors appear to be the cause, but the possible influence of the employed post-processing software has never yet been evaluated. The purpose of this study is to determine if there is variability in lumbar bone ADC related to the post-processing software.

A longitudinal observational cohort study to investigate the value of prognostic factors, here sensory profiles , and others, in the development of central sensitization in the low back pain population. A type 2 prognostic factor research following the PROGRESS framework. Sensory profiles are identified a prognostic factors which can predict the development of central sensitization in the low back pain population.

In France the prevalence of low back pain is 70 to 80 %. It's the leading cause of health expenditure in Europe and costs 900 million euros per year to health insurance in France. This is the second reason to consult a general practitioner. Acute low back pain is defined as low back pain lasts less than 6 weeks. It represents 60 to 70 % of low back pain but only 20% of the costs induced by low back pain in general. In fact, acute low back pain often heals spontaneously. Risk factors for acute low back pain and risk factors for chronic low back pain have been the subject of many publications. They remain very difficult to prevent in practice because of their multiplicity. Preventing acute low back pain is part of the prevention of chronic low back pain. Patient care management of low back pain is well codified and consensual in the various international recommendations. However, their application is sometimes very disparate and bad habits on both patients and professionals persist. Advices recommended in the case of low back pain are widely disseminated but their applications are little studied. In 2017, in France, health insurance started a "back pain" prevention campaign with the objective of raising awareness of good attitudes in the event of back pain. It made an initial assessment of the different knowledges concerning spinal pain in the general population but also in the medical population with the aim of improving them. It appears that number of patients would not consult physician in this case. The many proposals of care and the diversity of medical professionals, paramedics and other stakeholders, proposing to cure low back pain form as many different clinical pathways. Use of alternative or unconventional medicines is poorly assessed. In this context, it seems relevant to evaluate patient clinical pathways and patients' attitudes.

Questionnaire for patients who got a lumbar infiltration in our clinic. The patients will have to answer questions concerning their pain. (The lumbar infiltration itself is not part of this study)

Using a retrospective analysis of a large commercial claims database and a Medicare database, the investigators evaluated DDEs that have the potential to cause DDIs among chronic low back pain (cLBP) patients on long-term opioid analgesia, which metabolizes through the CYP450 enzyme system, concomitant with other CYP450-metabolized drug(s).

Low back pain is a very common disease. Among the persons suffering of acute low back pain, about 10% are at risk of developping chronic pain. A screening questionnaire assessing this risk has been developed and validated in Swedish and English (Orebro Musculoskeletal Pain Screening Questionnaire, Linton, 2003). The aim of our study is to validate a french translation of this questionnaire. Patients suffering from acute low back pain will be asked to fill in several questionnaires at day 0, and 6 and 12 month later.

Delayed anticipatory muscle activity response in deep low back and abdominal muscles has been observed in patients with low back pain, indicative of a pathological condition. Muscle activity onset is traditionally recorded by intramuscular electromyography, but there is a need for a less cumbersome recording method in large clinical studies. The purpose of this experimental study is to explore whether high-frame rate m-mode ultrasound and tissue velocity imaging could measure anticipatory muscle responses ("onset") in the abdominal muscles reliably and comparably accurate to intramuscular EMG.

This pilot study aims at styding the correlations between body mass index, waist circumference and the potential for positional adaptation of the pelvis to support overweight or obesity

The aim of this study was to determine the Turkish validity and reliability of ''Health Care Providers and Impairment Relationship Scale HC (HC-PAIRS)'' developed by Dr Rainville.

Cesarean delivery (CD) may trigger an increase in low back pain (LBP) intensity and induce core muscle weakness. This study will assess the correlation between low back pain intensity and core muscle strength of transverse abdominis and Lumbar multifidus among women who underwent CD and compare it with those without previous pregnancy.
