What does a positive Bragard Sign indicate?

• A. Sciatic neuropathy or nerve root traction/irritation
• B. Medial disc herniation
• C. Hamstring strain
• D. Radiculopathy caused by a lateral disc lesion

Answer: (A)

A positive Bragard Sign indicates sciatic neuropathy or nerve root traction/irritation. This sign is assessed during the evaluation for lower back pain and sciatica, typically following a straight leg raise test. If the straight leg raise elicits pain, lowering the leg slightly and dorsiflexing the foot can trigger pain along the distribution of the sciatic nerve, which is indicative of significant nerve involvement.

The Bragard Sign is particularly useful in differentiating between various forms of neuropathy and potential disc issues. A positive result suggests the presence of nerve root irritation, making it a critical examination tool for assessing conditions related to the sciatic nerve and lumbar nerve roots. Understanding the specific implications of a positive Bragard Sign can help healthcare professionals determine the best course of treatment and identify underlying causes of lower extremity pain.
