Unfortunately, there is not any literature on sensitivity but specificity is very high (84%) while the reliability of testing is low (Kappa = 0.21-0.26). The chart below differentiates the various positions for each nerve:Ī positive test is a reproduction of the neurological symptoms. All of these tests begin in the prone position. Prone knee bend testingallows for the assessment of the femoral, lateral femoral cutaneous, obturator, and saphenous nerves. Statistically ranges as seem below are not clinically helpful. The chart below distinguishes the defining characteristics for the testing of each the nerves:

Each of the tests would be deemed positive if the neurological symptoms are reproduced. All sciatic nerve tests begin in the supine position and a straight leg raise (SLR) is performed, i.e. Testing of the sciatic nerve can be done via combinations of four different positions to incriminate the sciatic, tibial, sural, and common peroneal nerves. This blog will discuss the 8 techniques of the lower extremity: sciatic, tibial, sural, common peroneal, femoral, lateral femoral cutaneous, obturator, and saphaneous nerves.

Lower limb tension tests (LLTT), also known as neural tension tests, are used to evaluates the length and mobility of the components of the nervous system.
