Positive trendelenburg's sign is seen in superior gluteal nerve (Gluteus mediusminimus) injury and not in Inferior gluteal nerve injury (Gluteus maximus).

It functions primarily between the flexed and the standing positions, as when rising from the sitting position, straightening from the bending position, walking uphill and upstairs, running and jumping.
