Trendelenburg's test is used to assess the strength of which muscle group?

Explanation:
The test evaluates the strength and control of the hip abductors that stabilize the pelvis during single-leg stance. When you stand on one leg, the gluteus medius (and minimus) on the weight-bearing side contracts to keep the pelvis level. If those abductors are weak, the pelvis drops on the opposite, unsupported side, giving a positive Trendelenburg sign. That’s why this test specifically reflects the function of the gluteus medius. The other muscles listed mainly act on the knee or hip flexion (quadriceps, hamstrings, iliopsoas) and don’t primarily control pelvis stability during single-leg stance, so they aren’t what this test assesses.
