In the analysis of the Erichsen Sign, what symptom indicates an issue?

• A. Pain in the sacroiliac joint
• B. Loss of muscle strength
• C. Swelling of the thigh
• D. Cramping in the calf

Answer: (A)

The Erichsen Sign is often evaluated to assess for sacroiliac joint dysfunction. When analyzing this sign, pain in the sacroiliac joint directly indicates an issue related to sacroiliac pathology or dysfunction. This type of pain can suggest conditions such as sacroiliitis or other inflammatory processes affecting the joint.

In the context of the Erichsen Sign, pain indicates that there is likely an overload or abnormal function of the sacroiliac joint, which can be a source of lower back or pelvic pain. Identifying this pain during the examination helps clinicians to understand the patient's condition better and direct appropriate treatment strategies.

The other symptoms listed, while they may indicate various issues in the lower extremity or musculoskeletal system, do not directly relate to the specific analysis of the Erichsen Sign or the sacroiliac joint. Thus, the presence of pain in the sacroiliac joint is the critical symptom that signals an underlying problem during the assessment.
