Welcome to the Chiropractic Australia  Journal Club.

The Journal Club has been established to allow busy clinicians convenient access to the latest research via Dropbox.

  • The Archive consists of approximately 3000 research articles taken primarily from the last 5 years along with some earlier key research sorted into 126 folders in DropBox.
  • The articles in each folder are sorted from newest to oldest (top to bottom).
  • The most recent articles will initially appear in the “Latest Research” folder. This folder will be added to every 2 weeks on the 1st and 15th of each month and with new articles replacing older articles which will be sorted into their relevant folders.
  • As we add new articles or sort them into folders it will automatically do the same to DropBox on your computer!
  • There is a “Submit an Article” folder so members can contribute new articles and fill the gaps with important past articles that are not yet part of the Archive!

Study Design. Controlled radiological study.

Objective. To explore whether impairment of neural excursion during the straight leg raise test occurs in patients with sciatic symptoms secondary to lumbar intervertebral disc herniation (LIDH).

Summary of Background Data. Earlier studies have shown that during the straight leg raise (SLR) test in asymptomatic volunteers tensile forces are consistently transmitted throughout the neural system and the thoracolumbar spinal cord slides distally.

Methods. Fifteen patients with sciatic symptoms due to subacute LIDH were studied with a 1.5 T magnetic resonance scanner. First, a spine specialist diagnosed the LIDH using conventional scanning sequences. Following this subjects were scanned using different scanning sequences for planning and measurement purposes. Displacement of the conus medullaris during the unilateral and bilateral SLR was quantified reliably with a randomized procedure and compared between manoeuvres.

Results. The results showed 66.6% less excursion of conus medullaris with SLR performed on the symptomatic side compared with excursions measured with SLR performed on the asymptomatic side (p ≤ 0.001).

Conclusion. In patients with LIDH, the neural displacement on the symptomatic side is significantly reduced by the compressing IVD herniation. To our knowledge, these are the first data in intact human subjects to support the limitation of neural movements in the vertebral canal with LIDH.
