This study attempted to investigate the validation of Phonation Threshold Power of Patients who have Functional voicedisorder. 50 subjects participated in the study (32 subjects were patients who had functional voice disorders and 20 subjectswere normal adults). The PAS (Phonatory aerodynamic system, model 6600, KAY electronics, Inc.) was used to measure thedata and to do the analysis. Data from the Phonation Threshold Power was measured multiplying Phonation ThresholdPressure and Phonation Threshold Airflow. Phonation Threshold Pressure and Phonation Threshold Airflow were measured bythe PAS protocol. Those were used because of the ease of phonation. The results of this study showed that the differences inPhonation Threshold Power between patients who had functional voice disorder and normal adults could become a significantindex. Patients who had functional voice disorder showed more higher figures than normal adults. The results of studyshowed that Phonation threshold Power is more sensitive than Phonation Threshold Pressure and Phonation Threshold Airflow. The measured data also provided useful information for diagnosing patients with vocal fold.
