In physical assessment, what does a falling "tripod sign" during Bechterew's Test suggest?

• A. Normal reflex activity
• B. Pain indicating neurological compromise
• C. Positive for muscular strength
• D. Indication of joint dislocation

Answer: (B)

The falling "tripod sign" during Bechterew's Test is significant as it suggests the presence of pain that indicates neurological compromise. This test is designed to assess for any discomfort or difficulty that arises when a patient attempts to extend their legs or when they are in a seated position. If a patient exhibits the tripod sign—where they lean backward or prop themselves up with their hands to relieve discomfort—this typically points to underlying issues related to nerve root irritation or tension in the lower back and legs.

This response to the test indicates that further evaluation of neurological function is warranted, as it may reflect conditions such as radiculopathy or other neurological pathologies affecting the lower extremities. The tripod sign serves as a clinical indicator of potential pathology that needs to be addressed in the context of the patient's overall physical assessment.
