What is the indication for performing a Well Leg Raise?

• A. Hamstring strain
• B. Radiculopathy
• C. Medial disc herniation
• D. Sciatica

Answer: (C)

Performing a Well Leg Raise is specifically indicated in cases of a medial disc herniation. This test is utilized to assess for nerve root involvement and can help identify the presence of a herniated disc. When the patient is asked to raise the unaffected leg (the "well" leg), it may elicit pain or neurological symptoms in the affected leg due to the increase in intra-abdominal pressure that can cause the herniated disc material to compress the nearby nerve root. This response is particularly characteristic of a medial or central herniation, where the disc material protrudes toward the spinal canal and can affect the nerve roots that innervate the lower extremities.

In contrast, hamstring strains are typically assessed through different physical tests that evaluate the integrity and flexibility of the hamstring muscles. Radiculopathy indicates nerve root compression or irritation, which could be assessed through other tests that examine reflexes and sensation but are not directly implied by the Well Leg Raise. Lastly, while sciatica and radiculopathy might present similar symptoms, the Well Leg Raise more accurately targets the specific assessment related to a medial disc herniation, offering precise indications for diagnosis and highlighting its importance in evaluating lower back and leg pain.
