What condition does Braggard's test primarily assess?

Braggard's test is primarily utilized to assess lumbar disc herniation. During the test, the clinician elevates the patient's straight leg while maintaining the knee in an extended position. If this maneuver provokes symptoms such as pain or discomfort, it indicates possible irritation of the sciatic nerve, which can occur when a herniated disc compresses or impinges on nearby neural structures.

While sciatica, herniated nucleus pulposus, and spinal stenosis may involve similar symptoms or underlying pathophysiology, the specific focus of Braggard's test is to elicit and evaluate reactions that are indicative of a lumbar disc herniation. The outcome helps in localizing the source of the pain and determining an appropriate course of treatment. Hence, the test is a valuable diagnostic tool in identifying lumbar disc-related issues.
