What does a present Neri Sign indicate?

• A. Quadriceps strain
• B. Lower back sprain
• C. LS strain, SI lesion, or sciatic radiculopathy
• D. Hip joint dysfunction

Answer: (C)

A present Neri Sign indicates an issue related to the lower back, specifically, it is a clinical sign that suggests possible involvement of the lumbar spine, sacroiliac (SI) joint, or sciatic nerve. When the Neri Sign is positive, it typically presents as an involuntary flexion of the knee when the patient tries to bend forward at the waist. This response can occur due to pain or irritation in the lower back, reflecting conditions such as a lumbar spine strain, SI joint lesion, or sciatic radiculopathy.

Understanding this sign is important in the context of physical assessment, as it provides insight into the potential source of pain or dysfunction in the lower extremities. Other options, while they relate to the lower extremity, do not encapsulate the specific nature of the Neri Sign, which is primarily associated with nerve root irritation or mechanical issues in the lumbar region rather than isolated injuries to muscles, joints, or the hip.
