slump testA clinical test used to identify sciatica or dural irritation.
The patient sits at an end of the examining table and leans forward. The examiner holds the patient’s head and chin upright, then flexes the patient’s neck to identify changes in symptoms; if none are noted, the examiner passively extends one of the patient’s knees, again to identify changes in symptoms; if none are noted, the examiner passively dorsiflexes the patient’s ankle while the knee remains extended. The patient is then returned to original position and the test is repeated for the opposite leg.
Complaints of sciatic-type pain or reproduction of symptoms implies sciatica or dural irritation.
A test used to assess the effects of tension on the neuromeningeal tract (e.g., in nerve root injury, meningeal irritation, meningitis, disk disease, or central nervous system tumors). The patient is directed to sit slumped forward, flexing the entire trunk. The patient's foot is dorsiflexed and the knee is then extended. Inability to extend the knee fully or production of back or leg pain symptoms, or both, are positive signs. If no positive sign is elicited, then the patient actively extends the neck, and knee extension and pain are then reassessed. Variations of this test are used to target injuries to specific spinal nerves.
