Tight hamstrings
[edit]"The straight leg raise test is positive if pain in the sciatic distribution is produced between 30 and 70 degrees passive flexion of the straight leg."
Wouldn't tight hamstrings also result in discomfort/pain, thus being a false positive for disk herniation ? 69.196.160.115 (talk) 19:28, 21 November 2010 (UTC)
"Tight hamstrings" do not produce symptoms typical of sciatica (type and/or location), usually require more hip flexion, and resistance would be felt by the examiner. (But this resistance can be a means to protect the sciatic nerve from tension). In case of more proximal symptoms (low back/glutes/hamstrings), differentiation between neural involvement and muscular can also be done via dorsiflexion. If it reproduces patient's symtoms and modulates the response, there is probably neural involvment. 69.28.223.68 (talk) 15:51, 30 October 2017 (UTC)
