Dear Jill
It is likely to mean the patient has a problem with a nerve, after that it
gets difficult. I think it must also be remembered that these strong neural
tension type tests also stress the circulatory system and pain and
paresthesia may by coming from hypoxia.
When you look at the gross movts that are involved in a SLR it really is not
very specific. I would suggest that the difference between a
lordotic/anteriorly pelvic tilted person and a flexed posterior tilt could
be as much as 15 degrees in their SLR. In this test there are strong hip
knee and foot movts all of which can be the provoking factors to the nerve.
In the bad old days a positive SLR meant a slipped disc, I wish it were that
easy.
I know it is getting a little dated but I still like some of Butlers
rationale. To simplify look for the impingement along the course of the
neural system, including autonomic, for the offending interface. If
unsucessful try and desensitise the provoking movts with specific exercise
eg ant.
Hope this helps Regards Kevin Reese PT UK
