The tongue plays a crucial role in the swallowing process, and weakness in its muscles can lead to difficulties in bolus control, mastication, bolus transport, and oral residue. Reduced tongue strength is closely associated with dysphagia, a swallowing disorder that impairs the movement of food or liquids from the mouth, pharynx, or esophagus into the stomach. Measuring tongue strength is essential not only for diagnosing dysphagia but also for setting therapeutic goals and evaluating treatment effectiveness. However, Indonesia currently lacks accessible tools for assessing tongue strength and endurance or for providing tongue exercise therapy. Existing devices, such as the Tongueometer and Iowa Oral Performance Instrument (IOPI), are costly, difficult to access, and not well-suited for children. To address this gap, a prototype orofacial manometer (PMO) is needed-one that is affordable, child-friendly, and easy to use. TongueFit is an innovative orofacial manometer designed for both assessing and improving tongue strength and endurance. Similar to the IOPI, this prototype provides objective measurements while also incorporating a biofeedback feature in the form of a video game, enhancing engagement and participation in therapy, particularly for children. Additionally, TongueFit offers advantages in affordability, accessibility, and usability. It has been validated as a reliable and accurate tool for measuring tongue function. Given its potential, clinical trials are essential to evaluate the effectiveness of TongueFit in tongue strength and endurance therapy. These trials will support its broader clinical application and development, ensuring that it becomes a widely available tool for dysphagia management.
