BACKGROUND: Lumbar statilization exercise programs (LSEP) produce positive effects on clinical outcomes, but the underlying mechanisms remain fairly unexplored. Psychological and neuromuscular mechanisms can be involved such as a better activation of the lumbar multifidus which represents one possibility. OBJECTIVES: To determine the (1) effect of a LSEP on lumbar multifidus muscle thickness and activation, as measured with rehabilitative ultrasound imaging (RUSI), in patients with low back pain (LBP); (2) correlation between RUSI measures and any change in clinical outcomes following the LSEP; (3) reliability of RUSI measures in control subjects over 8 weeks...

Arthur R Kurzbuch, Didier Recoules-Arche
Lumbar spine revision surgery is considered as challenging and related to longer operation time and complications because of the loss of anatomical landmarks and the formation of postoperative epidural fibrosis. Minimal invasive lumbar spinal surgery techniques have been refined over the last 5 years but the reexposure of the dura, the formation of postsurgical scar tissue and related dural tears remain a source of complications. For lumbar spinal revision surgery we advocate the minimal invasive Extraforaminal Lumbar Interbody Fusion (ELIF) technique...

BACKGROUND: Exercise is considered an effective treatment strategy for non-specific chronic low back pain (NSCLBP).background In spite of the wide use of exercise protocols, it is not clear what type of exercise is more effective in decreasing pain, disability and normalizing muscle activation patterns in people with chronic low back pain. OBJECTIVES: To assess the effects of two exercise protocols (stabilization vs movement control) on pain and disability scores and the flexion relaxation ratio (FRR) of lumbar multifidus (LM) and iliocostalis lumbarum pars thoracic (ICLT) in people with extension related non-specific chronic low back pain...

Spinal epidural abscess is a severe, generally pyogenic, infection of the epidural space of spinal cord or cauda equina. The swelling caused by the abscess leads to compression or vascular disruption of neurological structures that requires urgent surgical decompression to avoid significant permanent disability. We share a rare case of Klebsiella pneumoniae spinal epidural abscess secondary to haematogenous spread of previous lung infection that presented late at our centre with cauda equina syndrome that showed good short-term outcome in delayed decompression...

Background context Prolonged microgravity exposure is associated with localized low back pain and an elevated risk of post-flight disc herniation. Though the mechanisms by which microgravity impairs the spine are unclear, they should be foundational for developing in-flight countermeasures for maintaining astronaut spine health. Because human spine anatomy has adapted to upright posture on Earth, observations of how spaceflight affects the spine should also provide new and potentially important information on spine biomechanics that benefit the general population...

BACKGROUND: The prevalence of sway back posture (SBP) is very high among elite gymnasts. This posture may be partly due to the improper function of lumbar multifidus muscles (LMM) as lumbar stabilizers muscles. PURPOSE: The aim of this study was to compare the thicknesses of LMM measured at rest and during the contraction elicited during an arm lift between elite gymnasts with SBP and normal posture. STUDY DESIGN: Observational, descriptive, comparative...
