To locate both gluteus medius and minimus in a sidelying position, you should perform what movement at the hip?

• A. Abduction
• B. Adduction
• C. Flexion
• D. Extension

Answer: (A)

The key action is hip abduction. Gluteus medius and gluteus minimus are the primary abductors of the hip, located on the outer aspect of the pelvis. In a sidelying position, lifting the top leg away from the midline engages these muscles to move the thigh outward and to help keep the pelvis level. This palpation-friendly position highlights their location because their contraction becomes most evident when the hip abducts rather than when it flexes, extends, or adducts. Adduction would bring the leg toward the midline and recruit other muscles; flexion targets the hip flexors, and extension targets the gluteus maximus and hamstrings. So, abducting the hip best locates and engages gluteus medius and minimus in this setup.
