The dynamic palatograph is an electrical apparatus that generates a visual display of constantly changing palatolingual contact as a function of time, using an artificial palatal plate with affixed electrodes. This paper describes a technique of speech therapy incorporating dynamic palatography for a cleft palate patient. The patient, a 6-year-old Japanese girl with a repaired unilateral cleft lip and palate, had been judged to demonstrate articulation disorders involving contact of the tongue with the hard palate or alveolus following surgical improvement of velopharyngeal function. Prior to therapy the tongue tended to contact the hard palate more posteriorly than normal. After therapy with the dynamic palatograph, palatolingual contact was normal in comparison with average speakers. Our findings suggest that the facility of constant visual indication of tongue posture to the clinician and patient during corrective speech therapy using dynamic palatography may expedite results with cleft palate patients in the speech clinic when implemented in a carefully structured treatment plan.
动态腭图仪是一种电子设备，它使用带有固定电极的人工腭板，根据时间生成不断变化的腭舌接触的视觉显示。本文描述了一种将动态腭图技术纳入腭裂患者言语治疗的方法。该患者是一名6岁的日本女孩，患有单侧唇腭裂且已修复，在腭咽功能手术改善后，被判定存在涉及舌头与硬腭或牙槽接触的发音障碍。治疗前，舌头与硬腭的接触往往比正常情况更靠后。使用动态腭图仪进行治疗后，与普通说话者相比，腭舌接触正常。我们的研究结果表明，在精心构建的治疗计划中实施动态腭图技术时，在矫正性言语治疗期间为临床医生和患者提供持续的舌头姿势视觉指示，可能会加快腭裂患者在言语诊所的治疗效果。
