How do you perform the Sicard Test?

• A. Immediatly after a + SLR, lower leg until pain diminishes and extend big toe
• B. Patient seated, flex the knee to 90 degrees
• C. Patient standing, raise the heel off the ground
• D. Patient supine, perform a deep squat

Answer: (A)

The Sicard Test is specifically utilized to assess for the presence of nerve root tension or irritation, particularly involving the L5 and S1 nerve roots. The correct method involves having the patient initially positioned in a way that allows for an easy evaluation of the lower extremities. In this test, the practitioner first performs a straight leg raise (SLR), monitoring for any reproduction of pain or symptoms, which indicates possible nerve root involvement. After identifying a positive SLR response, the next step is to lower the leg until the pain diminishes, and then to extend the big toe. The extension of the big toe is crucial as it places additional tension on the sciatic nerve and its branches, specifically targeting the nerve roots that could be contributing to the patient's symptoms. Conducting the test in this manner enables the examiner to isolate the specific nerve roots affected, reflecting the patient's underlying neurological condition. This approach is consistent with the principles of neurological assessment in the lower extremities, making it a valid method for identifying nerve root involvement in individuals with radicular pain or other related symptoms. In contrast, the other options do not align with the established procedure for the Sicard Test, as they either cover different assessment techniques focused on other aspects of lower extremity function
