Which of the following tests helps identify lumbar strain?

• A. Slump test
• B. Belt test
• C. Neri Sign test
• D. Lewin Standing Test

Answer: (C)

The Neri Sign test is specifically designed to assist in identifying lumbar spine issues, including lumbar strain. This test involves the patient standing and then performing trunk flexion, during which the clinician observes for any signs of discomfort or inability to flex. If a patient bends forward and exhibits sudden pain or a reflexive bending of the knee on the affected side, it suggests the presence of lumbar strain or related pathology.

Other tests mentioned address different aspects or locations of back pain or neurological issues. For instance, the Slump test is primarily used to assess for neural tension and is more indicative of nerve root involvement rather than a muscular strain. The Belt test is aimed at distinguishing between true lumbar pain and hip or pelvic pain, while the Lewin Standing Test evaluates the patient's ability to maintain a standing position while performing a controlled movement, which could indicate different spinal issues but is not as specific for lumbar strain. Therefore, the Neri Sign test provides a more direct assessment relevant to the identification of lumbar strain.
