Video Link

Background/Purpose

This test was initially used to spinal disc and nerve pathology. It was later used to interpret dysfunction of the facet joints. It's utility in accurately predicting facet issues was reported as being poor in a review by Stuber et al. This review did not consider the tests origins as a disc or nerve test.
It is likely helpful to consider the multitude of different structures that are being stressed by this particular test.
There are multiple responses that may occur with this test and there is little validity to what the responses indicate.
Pain (with or without radiation) may indicate a disc lesion, facet irritation due to compression or stretch/strain of the joint capsule), muscle strain, or nerve irritation.

Procedure

The clinician has the patient slowly extend and rotate to one side and then the other.
Note any pain or radicular symptoms that may result.
Additional testing is indicated to better isolate individual structures.
Performed: Unilaterally
