What is a positive finding in the Sicard Test?

• A. Increased range of motion in the ankle
• B. No pain or discomfort during the test
• C. Radiating pain down posterior aspect of the LE
• D. Local muscle cramping

Answer: (C)

A positive finding in the Sicard Test is indicated by radiating pain down the posterior aspect of the lower extremity. This test is primarily used to assess for nerve root irritation, specifically the S1 and S2 nerve roots, which can occur due to conditions like herniated discs or spinal stenosis. When performing the Sicard Test, the clinician typically extends the great toe while the patient is positioned in a way that allows for potential nerve root irritation. The presence of radiating pain suggests that the sciatic nerve or its branches may be affected, which aligns with the expected outcome that signals a positive test result.

The other choices do not reflect the implications of the Sicard Test. Increased range of motion in the ankle does not correlate with nerve root irritation. No pain or discomfort during the test indicates a negative result, suggesting no underlying nerve issues. Local muscle cramping could be a reaction to other factors but does not specifically indicate nerve root involvement like radiating pain does.
