How is Hibb Test performed?

• A. Patient sitting, flexing both knees
• B. Patient prone, flex knee and use calf as a lever
• C. Patient standing, weight on one leg
• D. Patient supine, rotating the leg

Answer: (B)

The Hibb Test is performed with the patient in a prone position. This position allows for the examination of the hip joint's internal rotation. During the test, the examiner flexes the knee and uses the calf as a lever to facilitate the movement of the hip joint. This action helps evaluate any potential restrictions or pain associated with hip pathology.

Using the knee as a lever in this position can effectively isolate the hip joint to assess its function. A positive response (pain or limited motion) may indicate conditions such as hip joint irritation or pathology, including issues related to the ischiofemoral space or hip joint inflammation.

In contrast, performing the test in other positions, such as sitting, standing, or supine, either does not facilitate the specific assessment of internal rotation at the hip or may engage different muscle groups that could alter the findings. Therefore, the specific mechanics of the Hibb Test and the choice of patient position are critical in ensuring an accurate and effective assessment of the hip joint.
