      <textblock>
        The Trendelenburg test is commonly used to assess hip abductor weakness. However, it is&#xD;
        unclear which hip position during this test best isolates gluteal muscle function. This study&#xD;
        will measure gluteus medius and minimus activation and hip abduction force in 30 healthy&#xD;
        participants performing the Trendelenburg test. Different hip flexion, extension, adduction&#xD;
        and abduction angles will be evaluated to determine which position optimally targets the&#xD;
        gluteal muscles. Results may enhance utilization of the Trendelenburg test in clinical&#xD;
        practice.&#xD;
