What nerve-related risk is associated with aggressive hamstring stretching?

• A. Tension or irritation of the sciatic nerve; radicular symptoms can be reproduced; avoid nerve provocation.
• B. Injury to the femoral nerve.
• C. Irritation of the ulnar nerve.
• D. Damage to the phrenic nerve.

Answer: (A)

Aggressive hamstring stretching can place tension on the sciatic nerve, which runs from the pelvis down the back of the leg. When you push a stretch too far, the nerve pathway can become irritated, producing radicular symptoms—pain, numbness, tingling, or burning that travels down the leg. That’s why nerve provocation should be avoided during stretching. The other nerves listed aren’t typically involved with a hamstring stretch: the femoral nerve is in the front of the thigh, not in the posterior chain being stretched; the ulnar nerve travels in the arm; and the phrenic nerve controls the diaphragm. So the primary nerve-related risk with aggressive hamstring stretching is sciatic nerve tension and the resulting radicular symptoms.
