The purpose of this study is to investigate prosodic characteristics in the speech of adults with cerebral palsy through a comparison with the speech of normal speakers. Ten speakers with cerebral palsy (6 males, 4 females) and 6 normal speakers (3 males, 3 females) served as subjects. The results revealed that, compared to normal speakers, speakers with cerebral palsy showed a slower speech rate, a larger number of intonational phrases(IPs) and pauses, a larger number of accentual phrases(APs) per IP, a longer duration of pauses, and more gradual slopes of [L +H] in APs. However, the two groups showed similar tone patterns in their APs. The results also showed mild to moderate correlations between speech intelligibility and the prosodic properties which showed significant differences between the two groups, suggesting that they could be important prosodic factors to predict speech intelligibility in the speech of adults with cerebral palsy.

The relations between words intelligibility and sentences intelligibility were tested on adults with cerebral palsy(athetoid type). Intelligibility is used as an important evaluation value in the field of diagnosis and therapy of dysarthric patients. In order to develop one syllable phonetic contrast intelligibility test using specific phonetic contrasts, the correlation with sentences intelligibility was tested to find out the validity. Pearson's simple correlation coefficient was .83 that shows a high correlation. Also, comparing the range and standard deviation given by seven evaluators on each subject, it was shown that when evaluating patients of moderate intelligibility, words intelligibility was more reliable than sentences intelligibility.

Intelligibility measurement is one criterion for the assessment of the severity of speech disorders especially of dysarthric persons. Rate control, usually rate reduction, is used with many dysarthric speakers to improve their intelligibility. The purpose of this study is to compare how change intelligibility of speech produced by cerebral palsic speakers according to three speaking conditions. Speech samples were collected from 10 adults with cerebral palsy were asked to speak under three speaking conditions-(1) naturally(control), (2) more slowly(rate control), (3) louder and accurately(clear speech). In a perception test, after listening to the speech samples, a group of three judges were to write down whatever they heard. The result showed that total cerebral palsic subjects were divided into two subgroups according to their intelligibility according to three speaking conditions. Some subjects showed that speech intelligibility increased greatly if asked to speak 'louder and more accurately'. and the others showed no difference of intelligibility according to the speaking conditions. This study suggested that it would be useful clinically to find out the best instruction to improve intelligibility suitable for each speaker with cerebral palsy.

Purpose : The purpose of this study was to investigate changes in the gross motor function, self-esteem and social ability of children with cerebral palsy from group exercise program for physical and emotional interaction. Methods : Five cerebral palsy children who live in U city were recruited this study. Exercise sessions were held for 1 hour per session, once per week, for 12 consecutive weeks. At pre-treatment and post-treatment, subject were tested gross motor function measure, self-esteem and social ability. Results : After 12 weeks of paticipation in the group exercise program for physical and emotional interaction, there were improvements for gross motor function measure, self-esteem and social ability. Conclusion : Group exercise program for physical and emotional interaction can improve gross motor function, self-esteem and social ability.

Calcaneal or calcaneovalgus deformity can occur after surgical treatment of equinus or eguinovarus deformity in cerebral palsy patient. It is a serious complication and the results of many conservative and operative treatments are reported unsatisfactory. We experienced one case of both calcaneovalgus deformity following operative treatment of diplegic equinovarus deformity in a spastic cerebral palsy patient and report about the result of the treatment.

The present study examined two acoustic characteristics(duration and intensity) of vowels produced by 4 cerebral palsic adults and 4 nondisabled adults in conversational and clear speech. In this study, clear speech means: (1) slow one's speech rate just a little, (2) articulate all phonemes accurately and increase vocal volume. Speech material included 10 bisyllabic real words in the frame sentences. Temporal-acoustic analysis showed that vowels produced by two speaker groups in clear speech(in this case, more accurate and louder speech) were significantly longer than vowels in conversational speech. In addition, intensity of vowels produced by cerebral palsic speakers in clear speech(in this case, more accurate and louder speech) was higher than in conversational speech.

본 논문은 뇌의 수직단면에 대하여 촬영된 자기공명영상에서 뇌 영역을 분리한 후 백질과 회백질 및 뇌척수액을 분리하고 각각의 체적을 산출하기 위한 것이다. 본 연구는 먼저 뇌의 자기공명영상에서 영상의 배경 및 뇌 내부를 둘러싸고 있는 외피 및 지방층으로부터 뇌 영역 전체를 분리하였으며, 부분체적의 문제(partial volume artifact)에 의해 명암값의 번짐 현상을 보이는 뇌의내부 영역에서 각 성분의 부분체적을 산출하여 각 조직을 분리하기 위한 명암 값을 결정한 후 백질과 회백질 및 뇌척수액의 영역을 분리하였다. 본 연구는 뇌의 위축을 보이지 않은 정상인의 자기공명영상을 대상으로 하였으며, 향후, 이러한 연구 결과는 알쯔하이머 병이나 뇌성마비 등과 같은 퇴행성 뇌질환 환자의 뇌 위축정도를 객관적으로 진단하는 방법으로 사용될 수 있도록 하는데 있다.

Purpose: The purpose of this study was to determine whether there are any differences, with and without a toe spreader (TS), in dynamic foot pressure distribution in children with spastic diplegic cerebral palsy. Methods: Dynamic foot pressure recording using the RSscan system were obtained during walking in 12 participants (male=7, female=5) with and without TS. Mean force was measured for four different plantar regions; great toe, forefoot, midfoot, hindfoot. Displacement of center of pressure (COP), velocity of COP displacement and stance time were also measured during gait. Results: TS walking exhibited statistically significant decrease of mean force under great toe and forefoot (p<0.05), compared with a barefoot walking. Also, TS walking exhibited statistically significant increase of antero-posterior displacement of COP (p>0.05). Conclusion: These findings indicate the potential clinical utility of toe spreader to correct dynamic foot pressure during stance phase in children with spastic diplegic cerebral palsy.

The purpose of this study was to identify the acoustic properties of 9 word initial Korean plosives in the speech of adults with cerebral palsy. Normal adults and two groups of adults with cerebral palsy (athetoid group and spastic group) participated in this study. Speech material included monosyllabic CVC real word pairs. Among the various acoustic properties of plosives, the aspiration duration was measured. Adults with cerebral palsy exhibited different patterns of aspiration duration for triplets of Korean plosives compared to normal adults. In addition, the plosive production of spastic group was distinguished from that of athetoid group. Such acoustic characteristics of plosives of adults with cerebral palsy may negatively affect the intelligibility of their speech.
