This lady, named Jane, is lying on the ground, she has an itch on her back. A friend of hers, Nancy, who we never see as she's off camera, is helping Jane relieve that itch by holding on to Jane's ankles and sliding her 6 inches backwards and forwards vertically along the wooden floor many times over in a loop. The camera is on a fixed tripod and doesn't move throughout. The intense relief shows on Jane's face. Jane doesn't talk at all but does make appropriate sounds showing how relieved she is all the while keeping her eyes open and looking at the camera throughout.
