Understanding the Bowstring Sign (or Slump Test Variation) Assessment
To assess for **Sciatic Nerve irritation or tension** due to disc herniation or other space-occupying lesions. *Note: This is often an extension of the Straight Leg Raise (SLR) test.*
Watch How It's Done
How do I start?
Patient is supine. The affected leg has been passively raised into a position that reproduces their leg pain (positive SLR).
What happens?
The examiner flexes the patient's knee slightly (to relieve tension) and then firmly **presses into the popliteal fossa (the 'bowstring')** behind the knee.
In Plain English
What Does a Positive Result Mean?
The sudden reproduction of **radicular pain (shooting pain or numbness)** into the patient's calf or foot when pressure is applied in the popliteal fossa.
Helpful Tip:
This maneuver places direct pressure on the already taut sciatic nerve.
Safety First
This guide is to help you understand what happens in a clinic. Do not try to diagnose yourself. If you have severe pain, swelling, or cannot put weight on your leg, please visit an urgent care center or your doctor immediately.
