Results Increased paraspinal muscular activity at convex side of scoliotic curve is well known and documented finding. Main directions of research are related to structural changes in muscles and regulation of muscular contractility. In most cases the myopathic changes are considered as the consequence of the postural deformity. Very little information is available on the mechanisms by which su...

Regulating spinal motion requires proprioceptive feedback. While studies have investigated the sensing of static lumbar postures, few have investigated sensing lumbar movement speed. In this study, proprioceptive contributions to lateral trunk motion were examined during paraspinal muscle vibration. Seventeen healthy subjects performed lateral trunk flexion movements while lying prone with pelv...

OBJECTIVE To evaluate the relationship between the cross sectional area (CSA) and isokinetic strength of the back muscles in patients with chronic low back pain. METHOD Data of twenty-eight middle-aged patients with chronic back pain were analyzed retrospectively. CSAs of both paraspinal muscles and the disc at the L4-L5 level were measured in MRI axial images and the relative CSAs (rCSA: CSA...

Abstract Objective The paraspinal muscles have been extensively studied on axial lumbar magnetic resonance imaging (MRI) for better understanding of back pain; however, the acquisition measurements mainly relies manual segmentation, which is time consuming. study objective was to develop and validate a deep-learning–based program automated quantitative major spine components MRIs, in particular...

An 18-year-old boy presented with headaches, vomiting, recurrent seizures, and altered sensorium.He had extensive muscle hypertrophy on examination. MRI revealed multiple cysts in different stages in brain parenchyma, scalp, extraocular muscles, neck, chest wall, abdominal wall, paraspinal, gluteal, pelvic, and limb muscles (figure). The patient received steroids and antiepileptic drugs and had...

Results: Needle electromyography revealed continuous motor unit activity in the 50to 70-Hz frequency during the resting state for all the muscles sampled, which suggests the possibility of neuromyotonia. After ruling out possible secondary causes, we treated the patient with intravenous immunoglobulin, considering primary neuromyotonia. The body ache improved by 100% on the visual analogue scal...

A 41-year-old man with recent intravenous drug use presented with 2 weeks of progressively worsening neck and low back pain, four days of bilateral upper and lower extremity weakness, and urinary retention. Magnetic resonance imaging (MRI) revealed a T2/STIR hyperintense posterior epidural collection, suggestive of a spinal epidural abscess (SEA), extending throughout the epidural space of the ...

OBJECTIVE To quantify the activation of the paraspinalis muscles (multifidus and erector spinae) at different walking velocities and slope with surface electromyography. METHODS This study was a prospective experimental study involving ten healthy male participants. Surface electrodes were placed over the multifidus and erector spinae muscles at the L5 and L3 level. After the electrode was pl...

OBJECTIVE To determine whether stature recovery and paraspinal muscle activity can be altered in individuals with and without chronic low-back pain by assuming different unloading positions. DESIGN A case-control study considering the effects of unloading position on stature recovery in individuals with and without chronic low-back pain. BACKGROUND Stature recovery has been documented to be...
