본 연구는 시각적인 장애를 호소하는 ADHD로 진단받은 아동의 유형별 시각 기능의 특징을 확인하고자 하였 다. 연구 대상자는 ADHD로 진단받은 아동 49명으로 시각기능이 정상범위에서 벗어난 경우이다. Korean-ADHD Rating Scale을 이용하여 ADHD 유형을 알아보았고 시각기능 검사를 통해 시각 기능의 문제를 알아보았다. 시각의 문제를 가지고 있는 ADHD 아동들은 부주의 유형(69.4%)이 가장 많았으며 시력은 좋지만 시각 기능 문제가 드러난 경우도 50% 정도 되었다. 주의력결핍 유형에서 근시 관련 시각장애, 과잉활동형 유형에서 난시 관련된 시각장애가 높 게 나타났다. 버전스 기능 장애에서는 폭주부족이 가장 많았으며 유형별 차이는 나타나지 않았다. ADHD 아동의 유형 별 시각장애의 특성은 차이가 나타나므로 시각 기능 장애의 검사와 선별을 통해 아동의 문제행동에 접근하는 것이 필요하다.

The objective of this study is to identify the visual function impairment of children with each type of attention deficit hyperactivity disorder(ADHD). The subjects of this study were 49 children diagnosed with ADHD with visual function out of the normal range. The type of ADHD was investigated using the Korean-ADHD Rating Scale and visual function test. The attention deficit type(69.4%) of ADHD was the most common type among children with ADHD with vision problems. Although their overall naked-eye visual acuity was good, about 50% of the subjects showed problems with visual function. For those with the attention deficit type of ADHD, the myopia-related refractive error was high. For those with the hyperactivity type of ADHD, the astigmatism-related refractive error was higher. For those with vergence function disorder, convergence insufficiency was the most common. As there were differences in the visual impairment characteristics of children with different types of ADHD, it is necessary to approach a child's problem behavior through examination and screening for visual function disorders.

본 연구는 비전테라피가 시각 문제를 가지고 있는 ADHD 경향 아동의 증상과 시지각 기술을 향상시키는지 알아보고자 한다. 본 연구의 대상자는 ADHD 경향이 있는 아동 중 시각적인 문제를 가지고 있는 아동 10명이다. 비전 테라피 전· 후로 시각 기능 검사, 시지각 운동협응 검사, 시지각 기술 검사, ADHD 평가척도 검사를 실시하였다. 비전 테라피는 주 2회, 6개월∼1년 동안 실시되었다. 비전테라피 후에 대상자 모두 시각기능의 시력, 입체시, 버전스 범위, 폭주 근점에서 정상 범위에 도달했으며, 시각 기능과 시지각 기술이 향상되었고 ADHD 증상에 대한 점수가 낮아진 것으로 나타났다. 따라서, 비전테라피가 ADHD 경향을 가진 아동들의 증상과 시지각을 개선하고 시각문제를 해결하는 데 활용될 수 있는 것으로 보인다.

The purpose of this study is to determine whether vision therapy improves symptom and visual perceptual skills in children with attention deficit hyperactivity disorder tendency who have visual problems. The subjects of this study were 10 children. Before and after vision therapy, the visual function test, developmental test of visual-motor integration, test of visual perceptual skills, and ADHD rating scale test were performed. Vision therapy was conducted twice a week for a period of 6 months to 1 year. After vision therapy, all subjects achieved normal ranges of visual function, sensory fusion, stereoacuity, vergence function, and convergence. The visual function and visual perceptual skill were improved and the score for ADHD symptoms was reduced. Therefore, it seems that vision therapy can be used to improve the symptoms and visual perception of children with ADHD.

This study investigated age-related changes of cognitive function in Korean adults using the Korean-Developmental Test of Visual Percep-tion-2 (K-DTVP-2) and the Visual Motor Integration-3rd Revision (VMI-3R) test, and determined the main factors influencing VP and VMI in older adults. For this research, 139 adults for the K-DTVP-2 and 192 adults for the VMI-3R, from a total of 283 participants, were randomly and separately recruited in province, Korea. The present study showed that the mean score of the K-DTVP-2 and VMI-3R in 10-yr age incre-ments significantly decreased as age increased (K-DTVP-2, F=41.120, P<0.001; VMI-3R, F=16.583, P<0.001). The mean score of the VMI-3R and K-DTVP-2 were significantly decreased in participants in their 50s compared to those in their 20s (P<0.05). Age (t=-9.130, P<0.001), gen-der (t=3.029, P=0.003), and the presence of diseases (t=-2.504, P= 0.013) were the significant factors affecting K-DTVP-2 score. On the oth-er hand, age (t=-6.300, P<0.001) was the only significant factor affect-ing VMI-3R score. K-DTVP-2 score (Standardized β=-0.611) decreased more sensitively with aging than VMI-3R (Standardized β=-0.467). The two measurements had a significant positive correlation (r =0.855, P< 0.001). In conclusion, it can be suggested that VP and VMI should be regularly checked from an individual’s 50s, which is a critical period for detecting cognitive decline by aging. Both the K-DTVP-2 and VMI-3R could be used for determining the level of cognitive deficit by aging.

Objective To adapt and standardize the Motor-Free Visual Perception Test-3 (MVPT-3) to Koreans and investigate the change in visual-perceptual function using the MVPT-3 in healthy Korean adults.Methods The Korean version of the MVPT-3 was developed through a cross-cultural adaptation process according to 6 steps, including translation, reconciliation, back translation, cognitive debriefing, feedback, and final reconciliation. A total of 321 healthy Korean volunteers (mean age, 51.05 years) were recruited. We collected participant demographic data, such as sex, age, and years of education, and performed the Korean version of the Mini-Mental State Examination (K-MMSE) and MVPT-3. Internal consistency of the MVPT-3 and the relationships between demographic data, K-MMSE and MVPT-3 scores were analyzed. The results of this study were compared with published data from western countries including the United States and Canada.Results Total score on the MVPT-3 was positively correlated with years of education (r=0.715, p<0.001) and K-MMSE score (r=0.718, p<0.001). However, it had a negative correlation with age (r=?0.669, p<0.001). A post-hoc analysis of MVPT-3 scores classified age into 5 groups of ≤49, 50?59, 60?69, 70?79, ≥80 years and years of education into 4 groups of 0, 1?9, 10?12, ≥13 years. No significant differences in MVPT-3 scores were observed according to sex or country.Conclusion Visual perception was significantly influenced by age, years of education, and cognitive function. Reference values for the MVPT-3 provided in this study will be useful for evaluating and planning a rehabilitation program of visual perceptual function in patients with brain disorders.

Objective To compare visual-perceptual function between children with bilateral spastic cerebral palsy who have periventricular leukomalacia and unilateral spastic cerebral palsy without periventricular leukomalacia. Method Twenty-one children with spastic cerebral palsy (11 bilateral, 10 unilateral) were enrolled and their visual- perceptual function were assessed using K-DTVP-2 (Korean developmental test of visual perception 2). Results K-DTVP-2 in the bilateral group showed significant dysfunction when compared with the unilateral group. Among 6 sub-items of K-DTVP-2, scores related to visual closure and copying were particularly reduced in the bilateral group. There was discrepancy of verbal and performance IQ in the bilateral group which was not apparent in the unilateral group. Conclusion In children with spastic cerebral palsy, the bilaterally affected group had characteristic features of visual- perceptual dysfunction.

Objective To Investigate the synergic effects of short-term constraint-induced movement therapy (CIMT) and visual biofeedback training (VBT) in subacute stroke patients.Methods Thirty-two subacute stroke patients were enrolled and randomly assigned to one of three groups: short-term CIMT with VBT, VBT only, and control groups. We applied CIMT for an hour daily during VBT instead of the ordinary restraint time, referred to as ‘short-term’ CIMT. Short-term CIMT with VBT group received simultaneous VBT with CIMT, whereas the VBT the only group received VBT without CIMT for an hour a day for 2 weeks. The control group received conventional occupational therapy (OT) alone. Patients underwent the Purdue Pegboard Test, the JAMAR grip strength test, the Wolf Motor Function Test, the Fugl-Meyer Assessment (upper extremity), Motricity index and the Korean version of Modified Barthel Index test to evaluate motor functions of the hemiplegic upper limb at baseline, post-treatment, and 2 weeks after treatment.Results No significant differences were observed between short-term CIMT with VBT and VBT only groups. Both groups showed significantly higher scores compared to the control group in the WMFT and FMA tests. However, the short-term CIMT with VBT group showed significant improvement (p<0.05) compared with the control group in both grasp and pad pinch at post-treatment and 2 weeks after treatment while the VBT only group did not.Conclusion Short-term CIMT with VBT group did not show significant improvement of hemiplegic upper limb function of subacute stroke patients, compared to VBT only group. Larger sample sizes and different restraint times would be needed to clarify the effect.

This study investigated the influence of diabetes on cognitive decline between the diabetes and non- diabetes patients and identified the as-sociations between diabetes and cognitive function, visual perception (VP), and visual motor integration (VMI). Sixty elderly men (67.10±1.65 yr) with and without diabetes (n=30 in each group) who were surveyed by interview and questionnaire in South Korea were enrolled in this study. The score of Mini-Mental State Examination of Korean version (MMSE-KC), Motor-free Visual Perception Test-Vertical Format (MVPT-V), and Visual-Motor Integration 3rd Revision (VMI-3R) were assessed in all of the participants to evaluate cognitive function, VP, and VMI in each. The score of MMSE-KC in the diabetic group was significantly lower than that of the non-diabetes group (P<0.01). Participants in the diabetes group also had lower MVPT-V and VMI-3R scores than those in the non-diabetes group (P<0.01, respectively). Especially, the scores of figure-ground and visual memory among the subcategories of MVPT-V were significantly lower in the diabetes group than in the non-diabetes group (P<0.01). These findings indicate that the decline in cognitive function in individuals with diabetes may be greater than that in non-di-abetics. In addition, the cognitive decline in older adults with diabetes might be associated with the decrease of VP and VMI. In conclusion, we propose that VP and VMI will be helpful to monitor the change of cognitive function in older adults with diabetes as part of the routine management of diabetes-induced cognitive declines.

본 논문은 간헐성 외사시 수술 이후 시각 기능과 입체시 기능을 평가하였다. 본 연구의 대상자는 간헐성 외사시로 진단받고, 사시 수술을 받은 18명(남: 10명, 여: 8명)으로 평균연령은 12.06±5.43세이다. 연구대상자들은 사시수술을 1회 받은 경우가 72.2%, 2회 받은 경우가 27.8%이었다. 이들을 대상으로 시각 기능과 입체시 기능을 검사하였다. 자료 분석은 빈도분석과, 교차분석, 상관관계 분석을 이용하였으며, 통계학적 유의성은 p<.05로 설정하였다. 사시수술 후의 편위 상태에서는 외편위는 72.2%로 가장 많았으며, 원거리 감각융합에서는 복시(50.0%), 억제(33.3%) 순이었다. 근거리 감각융합에서는 융합(50.0%), 복시(44.4%) 순이었다. 사시수술 후 원거리 입체시맹 대상자는 61.1%로 가장 많았으며 정상범위인 40-60arcsec인 대상자는 없었다. 근거리 입체시맹 대상자는 33.3%로 가장 많았으며 40-60arcsec인 대상자는 1.1%이었다. 간헐성 외사시 수술을 시행하였다 할지라도 편위상태, 입체시 및 감각융합에서 개선이 되지 않는 부분이 있는 것으로 나타났다. 따라서, 간헐성 외사시의 수술 전후에 사시에 대한 비수술적 방법을 통한 관리와 통제가 필요하다.

This paper evaluated visual function and stereoacuity function after surgery for intermittent exotropia. Subjects of this study were 18 patients (male: n = 10, female: n = 8) mean aged 12.06±5.43 years diagnosed with intermittent exotropia who underwent strabismus surgery. Of these subjects, 72.2% of the subjects underwent strabismus surgery once and 27.8% had it twice. Visual function and stereoacuity function were tested for these subjects. For data analysis, frequency analysis, cross analysis, and correlation analysis were used, and statistical significance was set at p<.05. Regarding the deviation state after strabismus surgery, exodeviation accounted for the most(72.2%), followed by diplopia(50.0%) and suppression(33.3%) for distance sensory fusion. Regarding near sensory fusion, fusion(50.0%) accounted for the most, followed by diplopia(44.4%). After strabismus surgery, subjects with distance stereoacuity blindness were the most at 61.1% and there were no subjects with a normal range of 40-60 arcsec. Near stereoacuity blindness subjects accounted for 33.3% and subjects with 40-60 arcsec accounted for 1.1%. Even after surgery for intermittent exotropia, there were some areas that did not improve in deviation state, stereoacuity, or sensory fusion. Therefore, it is necessary to manage and control strabismus through non-surgical methods before and after surgery for intermittent exotropia.

Purpose: This study was done to investigate effects on swallowing function following visual stimulation and swallowing promotion exercises before meals for elders with swallowing difficulties following stroke. Methods: Participants for this nonequivalent control pre-post test design were 72 elders with stroke. Convenience sampling method was used to assign participants to experimental (36) and control (36) groups. The intervention was provided for about 15 minutes at every lunch and dinner time for 4 weeks. Outcome variables were Gugging Swallowing Screen (GUSS) score, body weight, total caloric intake, self-efficacy for swallowing, and coughing episodes during meal times. Results: Fifty-one participants were women (72.9%) and 74.3% were stroke only patients. Patients in the experimental group took less time to finish their meals and a higher percent had solid chopped food compared to the control group. Differences were statistically significant. In ANCOVA analysis using GUSS score as a covariate, the only significant improvement after the intervention was self-efficacy for swallowing. Conclusion: Visual stimulation and swallowing promotion exercises could lead to improvement in self-efficacy for swallowing even if they did not decrease coughing episodes during meal time.

The purpose of this study was to identify the prevalence of visual and hearing impairment and to investigate the effect of visual and hearing impairment on depression and cognitive function in community-dwelling Korean elderly. Methods: The study population consisted of a representative community sample of 4,028 persons aged 65 and older fromthe Korean Longitudinal Study of Aging 2008. Depression and cognitive function were measured by CES-D 10-item scale and K-MMSE. Visual and hearing impairment were measured by 5-Likert scale. Data were analyzed using Rao-Scott x2 test, simple and multiple logistic regression. Results: The prevalence of visual and hearing impairment were 37.3% and 14.0%, respectively. Of the participants, the prevalence of depression was 58.4% and cognitive impairment was 50.6%. There were significant differences in depression and cognitive function according to visual and hearing impairment. Far vision and hearing impairment were predictors for both depression and cognitive impairment even after covariates had been adjusted. Conclusion:These data suggest that visual and hearing impairment in older adults may increase their probability of experiencing depression and cognitive impairment. Thus sensory impairment should be considered a risk factor for mental health and the cognitive function of elderly.

The author thought about how to explain visual functions in an easy-to-understand way to customers visiting the optical shops and provide easy customer consultation, and attempted to evaluate the usability and value of the educational webtoon for patient consultation by applying it to the optical shops's visitors. Survey study was conducted targeting 152 customers who visited optical shops A in Incheon from January to December 2023. In this study, consultation was conducted using educational webtoons to help the general public understand concepts that are difficult to understand, such as binocular vision function, the concept of heterophoria, prism lenses, and binocular balance. The areas of ‘understanding’, ‘interest’, ‘usability’, ‘necessity’, and ‘expression of expertise’ felt by the visitors who received counseling were scored and evaluated, and differences according to counseling method were evaluated using an independent sample t-test. Statistical verification was performed. When the optometrist only explained verbally, the score distribution was relatively low: 1.96 points for understanding, 2.06 points for interest, 2.96 points for usability, 4.20 points for necessity, and 3.19 points for expertise. When the optometrist provided explanations along with the book, understanding was 4.14 points, interest was 3.28 points, usability was 3.60 points, necessity was 4.17 points, and expertise was 3.55 points. When the optometrist explained with a webtoon, understanding was 4.57 points, interest was 4.96 points, usability was 4.18 points, necessity was 4.65 points, and expertise was 3.15 points. When explanations were given only verbally, all items showed the lowest scores, whereas consultations using webtoons showed 4 points or more (excellent) in all items except the ‘expression of expertise’ item. It is evaluated that actively using webtoons in various consultation situations that occur in optical shops will help increase customer interest and concentration.

The purpose of this study was to investigate the effects of robot-assisted gait training using visual feedback on gait function in patients with post-stroke hemiparesis. Subjects were three female patients who are suffering from hemiparesis after stroke. Outcome measure was a dynamic gait index (DGI) before and after the intervention. The robot-assisted walking training was conducted by three subjects before the intervention, and the robot-assisted walking training was conducted four times daily per week. Our finding showed that the DGI was improved after the intervention in comparison with that assessed before the intervention. Robot-assisted gait training using visual feedback was clinically beneficial to facilitate the recovery of gait function in chronic stroke patients. In this study, it is necessary to improve the gait function after intervention.

This study aimed to identify the effect of a trunk stability exercise using visual feedback on the motor function, balance and activities of daily living (ADL) in patients with acute stroke. eleven subjects with post-stroke hemiparesis volunteered to participate in this study. All subjects underwent the trunk stability exercise for averaging 20 minutes daily for 4 weeks (total of 20 sesions). Assessment tools were made with Fugl-Meyer assessment scale (FMA), Berg balance scale (BBS), timed up and go test (TUG) and modified Barthel index (MBI) before and after the 4-week training period. FMA, BBS, TUG and MBI showed significant improvement after trunk stability exercise using visual feedback (p<0.05). This study demonstrates that a turnk stability exercise using visual feedback may be favorable for enhancing motor function, balance and ADL of patients with acute stroke. This study provides valuable information for future studies in this field. Further studies with wider range of subjects and longer experiment span are required to strengthen the results of this study.

목적 : 본 연구는 집단 작업 활동 프로그램이 지역아동센터 아동들의 시지각 및 운동기능을 향상시킬 수 있는지 알아보았다. 연구방법 : 지역아동센터를 이용하는 만 6∼9세 학령기 아동 5명을 대상으로 집단 작업 활동 프로그램을 실시하였 다. 프로그램은 놀이를 기반으로 시지각 및 운동기능을 촉진할 수 있는 요소를 포함하였고, 주 1회(90분) 총 9회기 로 진행되었다. 아동의 시지각 및 운동기능에 대한 프로그램 효과를 알아보기 위하여 프로그램 전과 후에 Motor Free Visual Perception Test-Third Edition(MVPT-3)와 Bruiniks-Oseretsky Test of Motor Proficiency 2nd Edition(BOT-2) 평가를 실시하여 두 시점의 평가 결과를 비교하였다. 결과 : 집단 작업 활동 프로그램은 지역아동센터 아동의 시지각 및 운동기능을 향상시키는 효과가 있었다. 결론 : 본 연구는 지역아동센터 아동들의 시지각 및 운동기능의 발달 촉진에 있어서 집단 작업 활동 프로그램의 효과를 보여주었다. 이러한 경험적 증거는 발달을 촉진하는 작업 활동이 지역사회에 적용되고 확대될 수 있는 근거를 제시한다.

Objective : The current study investigated the effectiveness of group occupational activity program in increasing visual-perception and motor function of children in Community Children Center. Methods : Five children aged between 6-9 years in a community children center participated in the group occupational activity program. The program was designed to facilitate children's visual-perception and motor function based on play occupations. We examined performances of MVPT-3 and BOT-2 before and after the program. Results : Children who participated in the group program showed significant increases in visual perception and motor function. Conclusion : The study revealed the effectiveness of group occupational activity program in promoting visual perception and motor function of children in a community children center, which suggests the possibility of application of occupational activity toward low-income children in the community.

The purpose of this study was to investigate the effects of occupational therapy with collage on the visual perception and hand function for the children with mild mental retardation(MR). This study was held at P Developmental Center using 20 children with mild MR who received treatment for 12weeks. The two groups were divided into the group that participated in both the collage program and occupational therapy(2times per week, 1day collage, 1day occupational therapy) and the group that only received occupational therapy(2times per week, both times occupational therapy) 10 participants were randomly assigned to the two groups, The results showed that the study group increased in both visual perception and hand function(p<.05), while the control group only showed slight increases in hand function (p<.05). In conclusion, this study indicates that occupational therapy using a collage program increased the abilities of visual perception and hand function for children with mild MR.
