Patient/Therapist Position and Procedure: Pt is seated on edge of table, feet hanging off the table. Pt is instructed to “slump” over into thoracic and lumbar flexion. Pt has hands behind his/her back. Pt is asked to keep neck and head in neutral (no flexion). If there are no reproduction of neurological symptoms, the PT progresses to the slump test modifications.
*Note- Unaffected leg should always be tested first.
Interpretation: + indication when pain is reproduced with comparable symptoms; if pt is unable to extend (affected) knee due to pain and then the pain is relieved when overpressure of the cervical spine is released the pt actively extends their neck.
Statistics: Sensitivity 84%, Specificity 83%
