What is a positive indication in the Nachlas Test?

• A. Reduced muscle strength
• B. Patient points to an area of pain indicating site of involvement
• C. Increased flexibility
• D. Decreased pain upon movement

Answer: (B)

In the Nachlas Test, a positive indication is characterized by the patient pointing to an area of pain, which signifies the involvement of a specific structure in the lower extremity, typically related to the lumbar spine or sacroiliac joint. This test is designed to assess the integrity of these structures and can help in diagnosing conditions like sacroiliac joint dysfunction or lumbar spine issues.

Identifying pain during the test is significant as it directs attention to potential sources of discomfort and can guide further diagnostic and therapeutic interventions. The focus on pain localization by the patient not only confirms an issue but also aids in differentiating between types of pain, such as that originating from muscular versus joint-related causes. This helps clinicians in developing a precise management plan tailored to the patient's presentation.
