The flip test of the back evaluates for lumbar radiculopathy and sciatica. The patient sits on the examination table with legs hanging off and the back kept in extension. The examiner stabilizes the patient’s thigh with one hand and holds the heel with the other, then slowly raises the affected limb by extending the knee. The test is considered positive if pain or radicular symptoms are reproduced or if the patient flips backward. Diagnostic accuracy is unknown! Read: https://wikism.org/Flip_Tes
