Mishneh Torah, Prayer and the Priestly Blessing
Prostration. After he has raised his head, subsequent to the fifth genuflection, the worshiper seats himself on the floor and "falls upon his face" and offers all the supplications he pleases. Genuflection, wherever mentioned, always refers to bending the knees. Kidah means "falling on the face" [with knees bent]. Hishtahvayah means stretching out the hands and feet, so that one is lying prone with face to the ground.
