Damage or disease processes affecting peripheral or central nervous system function, or both, can affect muscle coordination and alter muscle stiffness. Therefore, the biomechanics of orofacial and vocal tract structures should be taken into account when considering the movement patterns and network signaling in the neuromotor control system in health and disease. The purpose of this report is to summarize our evolving approach to and application of orofacial biomechanics in the context of movement disorders associated with dysarthria and craniofacial anomalies. We describe a new application for mapping stiffness in the lips for clinical application in pediatric and adult populations.
