Objective : The purpose of this study was to investigate the effect of left visual stimuli for reducing the severity of unilateral neglect. Method : This research used a reversal design(ABAB) of single case study. The subject was a 60-year-old male patient who had left unilateral neglect. Remedial approach is more valuable method than compensatory approach in term of reducing the unilateral neglect. One of the method of remedial approach is controlled sensory stimulation. Result : I performed the line bisection test before and after the stimulation, and while doing that, put blinking lights to the patient from the left side. The average errors in the line bisection test decreased in B B', the intervention period, compared with A A'. The MVPT left response behavior score increased from 13 to 18. Conclusion : This shows that the light stimulation is effective in the reduction of unilateral neglect.

The purpose of this study was to assess the effect on mandibular growth of botulinum toxin type A (BTXA) injection into the unilateral massester muscle of growing rats at three different growing stages. Thirty six male Sprague-Dawley rats were divided into three groups according to the age (group 1: 4 week-old, group 2: 5week-old, group 3: 6week-old). Then each group was randomly divided into 3 subgroups (control group, unilateral injection group, bilateral injection group). Experimental animals were sacrificed after 4 weeks. Then the jaw measurements were evaluated. The results were as follows: 1. In the group 1, mandibular body length, condylar height and coronoid process height of the unilateral group(BTXA side) and the bilateral group were shorter than those of the control group (p<0.05). 2. In the group 2, anterior region height, condylar height, coronoid process height of the unilateral group(BTXA side) and the bilateral group were shorter than those of the control group (p<0.05). 3. In the group 3, mandibular body length, condylar height, coronoid process height of the unilateral group(BTXA side) and the bilateral group were shorter than those of the control group (p<0.05). 4. There was no significant difference in mandibular measurements between the control side and the injection side in the unilateral group in all age groups (p>0.05).

뇌 혈류의 기능적 영상화는 간질병소의 국소화에 이용되고 있으며 측두엽성간질의 편측화에 여러가지 진단 방법이 이용되고 있으나 만족할만한 결과를 보이지 못하고 있다. 최근 PET또는 SPECT를 이용하여 측두엽성간질에서 발작 간에 측두엽 병소의 대사율 및 혈류의 감소가 나타나며, 이러한 소견은 발작 유발 병소의 편측화에 매우 유용할것이라는 보고들이 있다. 저자들은 측두엽성간질에서 간질 병소를 편측화 하는데에 $^{99m}Tc-HMPAO$ SPECT의 유용성을 평가 하고자 측두엽성간질 31예에서 발작 간의 $^{99m}Tc-HMPAO$ SPECT 소견, 뇌파, 자기 공명 영상 및 전산화 단층 소견을 비교하였다. SPECT 소견에 따른 나이, 병력 기간과 병발시 나이 등의 임상 지수 간에는 유의한 차이가 없었다. 31예의 환자중 23예에서(74.2%) 국소 뇌 혈류 감소를 보였으며 17예(54.8%)에서 측두엽에 관류 감소가 관찰 되었다. 비인두 뇌파 표준 뇌파는 24예(77.4%)에서 측두엽에 편측화를 보였으며 SPECT와 뇌파 양자가 모두 편측화된 경우 일치도는 8/12예 (66.7%) 였다. 16예에서 시행된 전산화 단층 영상은 모두 편측화를 보이지 못했으며 27예에서 시행된 자기 공명 영상에서는 단지 1예에서 편측화를 보였다. 이상의 결과로서 발작 간의 $^{99m}Tc-HMPAO$ SPECT는 측두엽성간질 병소의 편측화에 유용한 보조 검사로 생각된다.

Unilateral neglect is associated with stroke, a neurological disorder caused by cerebrovascular injury, and is a symptom of not recognizing or responding to the opposite stimulus of the cerebral hemisphere, mainly in the right cerebral hemisphere injury. In this paper, we implemented contents using Virtual Reality based on 10 items and contents of Korean Catherine Bergego Scale(K-CBS), which is used as a behavioral evaluation scale for unilateral neglect. Implemented contents can evaluate body disregard, motility disregard, visual and spatial disregard, auditory attention, etc., which are symptoms of unilateral neglected patients, and can confirmed progression of disease quantitatively by measuring time and rotation angle of head during visual recognition. This method is expected to be useful for rehabilitation training using convenient unilateral neglect diagnosis and its applied contents.

The purpose of this study was to investigate the effect of mental practice about functional performance of affected limb to unilateral neglect and ADL(Activities of Daily Living) in person with stroke. A single subject experimental research with ABA design was employed in this study. The experiment formed 18 sessions in total: 5 sessions for baseline, 10 sessions for mental practice treatment, and 3 sessions for the second baseline. Mental practice was composed of performing 3 functional activities(dressing clothes, make-up with materials and arrangement, folding clothes). It took 5 minutes at once and 15 minutes in total daily. The unilateral neglect was measured by reading test, writing test, and Baking Tray Task. ADL was assessed by COPM. The results indicated that unilateral neglect test scores were all reduced, and the score of COPM was clinically significant. Mental practice for performing of functional activities was effective method to reduce unilateral neglect and improve ADL in person with stroke.

Objective : This study aims to investigate the effect of half- eyes patching for the reduction of unilateral neglect of left-side hemiplegia. Methods : This study used the ABA design. He was required to wear the half- eyes patching during all the period of ADL because unilateral neglect causes many problems in the majority of ADL. The assessments for the unilateral neglect had been performed by the Line bisection and the Albert test once a session (day). Results : Regarding the Means of the errors to the Line bisection and the Albert test, the Means of the errors was not decreased during the period of the intervention (B) and was not decreased after the withdrawal (A'). Conclusions : Half-eyes patching was non-effective to r e lease the unilateral neglect. Further study is necessary to increase the sample size and the duration of experiments.

This study was undertaken to investigate the distribution of the chewing side preference and variations in the maximum bite force and facial morphology according to chewing side preference since unilateral chewing may cause morphologic and functional anomalies. 50 dental students who had no signs or symptoms of masticatory system and Angle's Class I relationship in posterior segments were selected, and divided into two groups, that is, 25 in bilateral chewing group(19 male and 6 female) and 25 in unilateral chewing group(10 male and 15 female). Maximum bite force was estimated ana posteroanterior cephalogram were measured ana statistically analyzed. The results were as follows : 1. Their were more students with bilateral chewing side preference($68\%$) and unilateral chewing side group consisted of right side preference($68\%$) and left side preference($32\%$). 2. There was no significant difference in the strength of max. bite force between the right and left side in bilateral chewing group. The bite force of the chewing side nab greater in the unilateral chewing group but less in the non-chewing side compared to those of bilateral chewing group with Bo significant difference. Max. bite force of chewing side was greater than that of non-chewing side in the unilateral chewing group(Female p<0.05). Max. bite force of males was about twice in that of females in both groups(p<0.05). Max. bite force of chewing side of the unilateral chewing group was similar to that of the bilateral chewing group, but that of non-chewing side was less than that of the bilateral chewing group. 3. In comparison of the facial morphology, there was no statistically significant difference in the size between the right and left side of the bilateral chewing group and between chewing and non-chewing side of the unilateral chewing group.

각종 음성질환에 있어서 음성검사는 진단뿐 아니라 치료를 위한 중요한 방법으로 알려져 왔다. 특히 수술전후 음성질환의 평가에는 음성검사 뿐 아니라, 후두스트로보스코피를 이용하여 비교함으로써 가능하다. 이중 후두스트로보스코피는 방법이 간단하여 직접 수술전후의 변화를 알 수 있는 장점이 있으나, 객관적인 자료로는 이용하기가 어려운 문제점이 있다. 후두스트로보스코피의 영상자료를 컴퓨터에 연결, 영상신호를 디지털화하여 후두의 움직임을 객관적으로 관찰하려고 시도되어왔다 특히 편측 성대마비 환자에서는 성대의 위치가 외전 될뿐만 아니라 피열연골의 위치가 마비 후 시간이 경과됨에 따라 외회전 하고 성대가 전방으로 위축되어 성대 막성부의 길이가 짧아지는 틀의 후두스트로보스코피의 영상을 보이고, 성대폴립환자에서는 수술전후에 폴립의 크기와 성문면적에 변화를 보이게 된다. 본 연구의 목적은 편측 성대마비와 성대폴립과 같은 각기 다른 두 질병에서 음성경사와 후두스트로보스코피를 이용한 이미지 화상분석을 통해 각 성대의 길이, 각도, 성문틈의 면적과 폴립의 크기등을 측정함으로써 수술전후의 차이를 알아보고, 이미지 화상분석과 음성검사 사이에 어떠한 상관관계가 있는지를 알아보고자 하였다.
