In MMT for hip abduction with anti-gravity, what is the standard patient position?

• A. Side lying with the tested limb resting on the table; the bottom hip and knee flexed for stability; the top leg is raised with the hip and knee in neutral.
• B. Side lying with the bottom leg unsupported by the clinician in a position of 25 degrees of abduction.
• C. Supine with the tested limb in extension resting on a smooth surface or supported by the clinician.
• D. Seated with knees flexed over edge of table.

Answer: (B)

When testing hip abduction against gravity, you want the gluteus medius to work against the natural pull of gravity while the pelvis stays level. Lying on the side accomplishes this best. In this setup, the leg to be tested is on top, and the bottom leg rests on the table without the examiner providing support or stabilization. The hip is positioned so the leg moves into a modest amount of abduction—about 25 degrees from neutral—so the muscle is tested in a comfortable, midrange length that emphasizes true abductor strength rather than end-range compensations. This arrangement isolates the abductors by minimizing help from other muscles and by stabilizing the pelvis with the patient’s own control rather than with external support from the clinician. The supine position would place the test in a gravity-eliminated plane, and a seated position would alter which muscles are recruited and how the pelvis is stabilized, making them less ideal for assessing anti-gravity hip abduction.
