What condition does the Nachlas Test specifically indicate?

• A. Patellar tendinitis
• B. Non-specific low back pain
• C. Sciatic nerve entrapment
• D. LS/SI/facet/disc pathology

Answer: (D)

The Nachlas Test is designed to assess the integrity of the lumbar spine and the sacroiliac (SI) joints, as well as to identify possible pathologies associated with the lumbar spine, sacroiliac joints, facets, and intervertebral discs. When performing the Nachlas Test, the patient lies prone, and the examiner flexes the knee, bringing the heel toward the buttock. A positive sign is typically indicated by pain or discomfort in the lower back or down the legs, which suggests a potential issue with the lumbar spine or associated structures.

This test provides valuable diagnostic information specifically relating to the lumbar region and the sacroiliac joint, making it a useful tool in identifying conditions associated with disc pathology, facet joint problems, and sacroiliac dysfunction. Therefore, the correct answer is that the Nachlas Test specifically indicates lumbar/sacroiliac/facet/disc pathology.
