Questions this video answers

Above 18 years old

MRI-confirmed lumbar disc herniation

Radiating pain below the hip

Lasègue's (straight leg) / cross straight-leg test and the slump (neurodynamic) test

This study ultimately had 81 participants, and the subjects were above 18 years old, and they had an MRI confirmed disc herniation, and.
They had radiating pain below the hip.
What they looked at was Lasag's sign.
Cross straight.
Leg test, as defined here.
Used to assess lumbar nerve root compression. Additionally, there was a slump test.
Neurodynamic.
Test to assess whether a disc herniation or neural tension is contributing.
To the symptoms.
They had what they called the sciatica bothersome index. Never heard of this one before. An index in which patients report symptoms during sciatic episodes.
The old odi.
The Oswestry Disability Scale, of course, measures the level of disability and the VAs, which is, of course, your analog, visual analog scale. Most of the time we're gonna do it verbally, but those are really the tests that they were utilizing and pitching against, so to speak, or correlating with those MRI findings.
