Answer

Provocative maneuvers, such as the straight-leg raising test or the slump test, may provide evidence of increased dural tension, indicating underlying nerve root pathology. Attempts at pain centralization through postural changes (ie, lumbar extension) may suggest a discogenic etiology for pain and may also assist in determining the success of future treatment strategies.
