What does a positive result in Ely's Test indicate?

A positive result in Ely's Test indicates a tightness or contracture of the rectus femoris muscle, which is one of the quadriceps muscles. The test is performed by having the patient lie prone while the examiner passively flexes the knee towards the buttock. If the hip begins to flex off the examination table when the knee is being flexed, it suggests that the rectus femoris is not allowing for full knee flexion due to tightness or contracture.

This information is particularly relevant in evaluating conditions related to flexibility and function in the lower extremity. In contrast, the other options pertain to shoulder injuries or conditions, which are not related to Ely's Test, as the test specifically targets the knee and the hip relationship through the quadriceps muscle. Understanding this helps clarify that a positive finding in Ely's Test is specifically indicative of issues with the rectus femoris rather than with the shoulder or rotator cuff structures.
