Velopharyngeal Incompetence in Dysarthria：Pathogenesis, Evaluation and Treatment (review) / 中国康复理论与实践

ABSTRACT

Dysarthric patients often present velopharyngeal incompetence (VPI), characterized nasalization articulation for hypernasali-ty, which seriously impaired their communication. Research of evaluation of VPI is mainly about cleft palate and postoperative, few about the dysarthria. Some approaches, such as physiologic approach to rehabilitation, have been used to correct hypernasality, and prosthesis, such as palatal lift prosthesis (PLP) and nasal speaking valve (NSV), are also proved effectively. PLP has been widely used for hypernasality oversea, but fewer in China.
