OTFC Minute Modules: Bub Club Edition What is ATNR and why do we test it? The ATNR (Asymmetrical Tonic Nerve Reflex) is a reflex seen in babies which helps them learn hand-eye coordination and prepares them for later movements like reaching and rolling. As babies grow, this reflect should fade. If it sticks around too long, it may affect things like crawling, writing or focusing in school. | OTFC Group | Facebook
