What physical exam test is commonly used to assess for sciatica?

The Straight Leg Raise test is a widely used physical exam procedure to assess for sciatica. This test specifically evaluates the integrity of the sciatic nerve and can help identify nerve root irritation or compression, often caused by conditions such as herniated discs or spinal stenosis.

During the Straight Leg Raise test, the patient lies flat on their back, and the clinician raises one leg while keeping the knee straight. If raising the leg causes pain that radiates down the leg along the path of the sciatic nerve, this indicates a positive test and suggests that sciatica may be present.

Other tests like the Trendelenburg Test, Crunch Test, and Spurling Test serve different diagnostic purposes. The Trendelenburg Test assesses hip abductor strength and related issues, the Crunch Test evaluates abdominal muscle function, and the Spurling Test is used primarily to assess cervical radiculopathy. These tests are not directly focused on sciatica, making the Straight Leg Raise the most relevant for this specific assessment.
