Laryngeal DDK involve with the rate, pattern, and regularity (periodicity) in opening and closing of vocal fold. This study was aimed at investigating the characteristics of laryngeal DDK between nonfluent and fluent speakers. One with an ataxic dysarthria (with cerebellar lesion) and the other with stuttering, and 13 normal speakers were evaluated. L-DDK were analyzed with MSP (motor speech profile, CSL 4400). Measures of DDK included: DDKavr, DDKcvp, DDKjit, DDKavp. An ataxic dysarthric speaker and a stutterer showed more reduced rate and aperiodic L-DDK (both adductory and abductory movement) than normal speakers. But the average L-DDK period (ms) in adductory movement in a speaker with stuttering showed more decreased than the other. Results from this study are preliminary. Nonetheless, results of L-DDK produced by nonfluent speakers suggested the possibility to have relation with slow rate of phonatory initiation and connected speech. In the future, perceptual studies are needed in conjuction with acoustic and speech production.

Larynx plays an important role in phonation and protection of the respiratory tract during swallowing. The reduced anatomical and physiological function in elevation of larynx and glottis closure can cause problems in voice and swallowing. The present study investigated the Korean version of handicap index of dysphagia in elderly Koreans. Therefore, 60 normal elderly Koreans ranged from 65 to 95 and 20 normal Korean young adults aged from 20 to 25 were participated in this study to compare total (T), physical (P), functional (F), and emotional (E) index scores between two groups as well as among sub groups (60s, 70s, 80s) in elderly. For swallowing, total and sub dysphagia handicap index (DHI) scores, voice quality during /a/phonation following swallowing (saliva and water), intensity of coughing, and L-DDK were measured. The results showed that functional (P), physical (P), emotional (E) scores as well as total (T) score were significantly different between young adults and old adults in DHI(p<.05). Additionally, there was a negative correlation between total DHI score and intensity of coughing (r=-.51) as well as L-DDK (r=-.70). These findings suggest that a slow rate in vocal fold adduction and reduced intensity of coughing in the elderly affect swallowing function. Thus, recently translated Korean version of DHI may be useful as supplement in evaluating the swallowing problems in elderly people.

본 연구는 세 명의 연하장애환자들을 대상으로 후두관련기능의 개선을 목표로 한 치료적 노래부르기 중심의 음악중재를 시행하고, 각 사례 별로 관찰된 변화를 기술한 개별 사례연구이다. 중재는 개별 세션의 형태로 매 회기 30분, 주 3회씩 총 12회기 동안 진행되었으며, 시행된 프로그램은 호흡근 이완, 구강근육운동, 후두상승 유지를 위한 발성과 치료적 노래부르기 등의 순서로 구성되었다. 대상자들의 연하 및 말하기 기능, 삶의 질 등의 변화를 알아보기 위해 매 회기 후두교호운동속도, 최대발성시간, 음성 질 관련 항목 등을 측정하였고, 중재 전후로 설문을 통해 삶의 질을 평가하였다. 중재 과정에서 대상자의 기능적 특성에 따라 구분되는 변화의 양상이 관찰되었고, 중재 후에는 모든 대상자의 후두교호기능 및 음성 질 지표 측정값에 변화가 있었으며, 연하관련 삶의 질 평가점수도 증가하였다. 본 연구를 통해 치료적 노래부르기 중심의 음악중재프로그램이 다양한 원인에 의한 연하장애환자들의 후두관련기능 및 삶의 질 영역에 공통적으로 혜택을 줄 수 있다는 점과, 중재 시 대상자의 기능적 특성에 따라 고려해야 할 부분에 대해 구체적으로 알 수 있었다.
