Dysarthria is a speech disorder that stems from impaired muscle control due to lesions in the articulatory system, necessitating targeted rehabilitation exercises to strengthen affected muscles. Current devices used for rehabilitation often fail to accurately assess exercise execution, which limits their effectiveness. This study introduces a novel oral-motor rehabilitation device designed to overcome these limitations. The device features flexible sensors and a signal processing module that provides real-time feedback on training intensity. It is integrated with a mobile application that enables users to monitor their tongue's range of motion and track their progress through a calibration process that uses a simple moving average filter. A preliminary study was conducted with five healthy adult male subjects to verify the device's basic operational characteristics. The effectiveness of the device in improving muscle function and regulating training intensity was evaluated using the Iowa Oral Performance Instrument. The results showed promising outcomes in enhancing articulation and oral-motor skills, indicating that the device could effectively contribute to dysarthria rehabilitation. By addressing the gaps in current rehabilitation practices for dysarthria, the proposed device offers a comprehensive and personalized approach to oral-motor therapy. Its ability to provide immediate feedback and track progress can significantly enhance the rehabilitation process, potentially leading to better outcomes for patients with dysarthria.
构音障碍是一种言语障碍，源于发音系统损伤导致的肌肉控制受损，因此需要进行有针对性的康复训练来增强受影响的肌肉。目前用于康复的设备往往无法准确评估训练执行情况，这限制了它们的效果。本研究引入了一种新型口腔运动康复设备，旨在克服这些局限性。该设备具有灵活的传感器和信号处理模块，可提供训练强度的实时反馈。它与一个移动应用程序集成，该应用程序使用简单移动平均滤波器的校准过程，让用户能够监测舌头的运动范围并跟踪自己的进展。对五名健康成年男性受试者进行了一项初步研究，以验证该设备的基本操作特性。使用爱荷华口腔功能仪器评估了该设备在改善肌肉功能和调节训练强度方面的有效性。结果显示在增强发音和口腔运动技能方面取得了有希望的成果，表明该设备可以有效地促进构音障碍的康复。通过弥补当前构音障碍康复实践中的差距，所提出的设备提供了一种全面且个性化的口腔运动治疗方法。其提供即时反馈和跟踪进展的能力可以显著增强康复过程，有可能为构音障碍患者带来更好的治疗效果。
