The relationship between hip abductor muscle strength and iliotibial band tightness in individuals with low back pain

The relationship between hip abductor muscle strength and iliotibial band tightness in individuals with low back pain
Background: Shortening of the iliotibial band (ITB) has been considered to be associated with low back pain (LBP). It is theorized that ITB tightness in individuals with LBP is a compensatory mechanism following hip abductor muscle weakness. However, no study has clinically examined this theory. The purpose of this study was to investigate the muscle imbalance of hip abductor muscle weakness and ITB tightness in subjects with LBP. Methods: A total of 300 subjects with and without LBP between the ages of 20 and 60 participated in this cross-sectional study. Subjects were categorized in three groups: LBP with ITB tightness (n=100), LBP without ITB tightness (n=100) and no LBP (n=100). Hip abductor muscle strength was measured in all subjects. Results: Analysis of Covariance (ANCOVA) with the…

Chronic axial compression of the mouse tail segment induces MRI bone marrow edema changes that correlate with increased marrow vasculature and cellularity

We assessed effects of compressive forces to mouse tail segments of WT and TNF-Tg mice with SA, via contrast enhanced-MRI and histology. Normalized marrow contrast enhancement (NMCE) of uninstrumented WT vertebrae significantly decrease, threefold (p 0.01) from 8 to 12 weeks of age, while the NMCE of TNF-Tg vertebrae remained elevated. Compressive loading (6× body weight) increased NMCE twofold (p 0.02) within 2 weeks in WT tails, which was equal to 6× loaded TNF-Tg tails within 4 weeks. Histology conf… br

Sagittal spinal alignment in patients with lumbar disc herniation

Sagittal spinal alignment in patients with lumbar disc herniation
Abstract  A retrospective cross-sectional study was designed to evaluate total sagittal spinal alignment in patients with lumbar disc herniation (LDH) and healthy subjects. Abnormal sagittal spinal alignment could cause persistent low back pain in lumbar disease. Previous studies analyzed sciatic scoliotic list in patients with lumbar disc herniation; but there is little or no information on the relationship between sagittal alignment and subjective findings. The study subjects were 61 LDH patients and 60 age-matched healthy subjects. Preoperative and 6-month postoperatively lateral whole-spine standing radiographs were assessed for the distance between C7 plumb line and posterior superior corner on the top margin of S1 sagittal vertical axis (SVA), lumbar lordotic angle be…

Whiplash injury: 2% are permanently disabled

Whiplash injury: 2% are permanently disabled
Whiplash and whiplash-associated disorders (WAD) represent a range of injuries to the neck caused by or related to a sudden distortion of the neck. Whiplash is commonly associated with motor vehicle accidents, usually when the vehicle has been hit in the rear; however, the injury can be sustained in many other ways, including falls from bicycles or horses.Most cases of whiplash injury occur as the result of rear-end vehicle collisions at speeds of less than 14 mph. Patients present with:- neck pain and stiffness- occipital headache- thoracolumbar back pain and upper-limb pain- paraesthesiaOver 66% make a full recovery and 2% are permanently disabled.References:Whiplash injury.

Changes in paraspinal muscles and their association with low back pain and spinal degeneration: CT study

Changes in paraspinal muscles and their association with low back pain and spinal degeneration: CT study
This study was an ancillary project to the Framingham Study. A sample of 3,529 participants aged 40–80 years had a CT scan performed to assess aortic calcification. 187 individuals were randomly enrolled in this study. LBP in the last 12 months was evaluated using self-report questionnaire. Density (in Hounsfield units) of multifidus and erector spinae was evaluated on CT. The prevalence of intervertebral disc narrowing, facet joint osteoarthritis (FJOA), spondylolysis, spondylolisthesis and spinal stenosis were also evaluated. We used linear regression models to examine the association of paraspinal muscles density with age, sex, BMI, LBP, and spinal degeneration features. The results show that in our study, men have higher density of paraspinal muscles than women, young…

Spinal Decompression Therapy and Back Pain
The mystique of technology as a fix for everything extends to back pain — in particular, as spinal decompression therapy, an offering that has gained visibility as among the latest in spine care (along with laser treatment — this article applies to that approach, too). The method involves a mechanical device intended to separate vertebrae and thereby to relieve pain.
