What is step 2 in the Mennell Test?

• A. Erichsen's test
• B. Hibb Test
• C. Yeoman's Test
• D. Range of motion assessment

Answer: (A)

In the context of the Mennell Test, which is designed to assess for sacroiliac joint dysfunction, step 2 specifically involves performing Erichsen's test. This step is critical as it evaluates the responsiveness and possible pain in the sacroiliac region when pressure is applied to the joint. The test focuses on identifying any pain that may indicate instability or dysfunction in the joint.

The significance of Erichsen's test in this sequence is that it directly tests the sacroiliac joint in a way that can reveal the source of the patient's discomfort when combined with the findings from step 1 of the Mennell Test. Other tests like the Hibb Test, Yeoman's Test, and range of motion assessment, while they may provide useful information regarding lower extremity or pelvic mechanics, do not specifically represent step 2 in the Mennell Test process. Thus, identifying Erichsen's test demonstrates the proper implementation of the assessment protocol for diagnosing sacroiliac joint issues.
