Hello, I'm in the process of translating from English to Spanish a Physical Therapy report, and I am stumped with the term "step-to pattern." The sentence is "He is able to climb down stairs without a rail using a step-to pattern." The best I've been able to come up with is "un patrón de paso-a-paso," but I don't like it. I believe a step-to pattern would refer to his going down the stairs with one foot and then bringing down the other foot to meet it; although I'm not really sure if that's what it is. Would anyone know how to translate this? Thank you so much.
