Whereas this measurement has been helpful in assessing for variations in the mobility of the anterior one\u2010third of the tongue (tongue tip and apex), it may be insufficient to adequately assess the mobility of the posterior two\u2010thirds body of the tongue. A commonly used modification is to assess TRMR while the tongue is held in suction against the roof of the mouth in lingual\u2010palatal suction (LPS).<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>This study aims to explore the utility and normative values of TRMR\u2010LPS as an adjunct to functional assessment of tongue mobility using TRMR\u2010TIP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Cross\u2010sectional cohort study of 611 subjects (ages: 3\u201083\u00a0years) from the general population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Measurements of tongue mobility using TRMR were performed with TIP and LPS functional movements.
