    Abstract
    Objective : The purpose of this research was to investigate the effects of computer-based cognitive training on the cognitive function and instrumental activities of daily living in people with schizophrenia. Methods : The design of this research including a pre-test and a post-test study. For this study, the concentration, memory, executive function, and level of instrumental activities of daily living were used as dependent variables, and computer-based cognitive training (REHACOM) was used as an independent variable. Twelve subjects participated in the study. As an intervention, the concentration, memory, and executive function training program of REHACOM was conducted twice per week during and an eight-week period, 16 times in total. Results : As a result of the study, the patients demonstrated significant improvements in their concentration,memory, executive function, and instrumental activities of daily living (p<.05). Additionally, there was a significant correlation between memory and instrumental activities of daily living (p<.05). Conclusions : This study demonstrated that a computer-based cognitive training program is effective not only on the cognitive function, but also on the instrumental activities of daily living, in people with schizophrenia. As a future study, investigators need to consider research using a control group and a specialized cognitive training program applying various cognitive functions.

    김정운 | OH MYUNG HWA | Baik Ji Young and 1other persons | 2013, 21(1) | pp.15~26 | number of Cited : 14
    Abstract
    Objective : This study was conducted to examine the ADL and life satisfaction of the physically disabled at home and to look at their interrelationship and the factors that affect them. Methods : The subjects of this study were 102 physically disabled people staying at home who were aged 20or older. Their ADL and life ssatisfaction were measured using K-ADL and K-IADL, and a life satisfaction scale, respectively. Results : First, the subjects had overall low ADL and life satisfaction levels. Second, the correlation among KADL,K-IADL, and life satisfaction were significant, with the exception of the correlation between K-ADL and life satisfaction. In particular, their life satisfaction had a more significant correlation with their K-IADL than their K-ADL. Third, the examination of factors affecting their life satisfaction showed that mobility and the use of transportation influenced their life satisfaction. Conclusion : Intervention with I-ADL rather than B-ADL is considered to be necessary to enhance the life satisfaction of the physically disabled at home.

    A Study on the Clinical Utility of the Fall Efficacy Scale for Predicting Falls in Stroke Patients

    Park, ChangSik | Seung Heon An | 2013, 21(1) | pp.27~40 | number of Cited : 3
    Abstract
    Objective : This study was designed to evaluate the clinical utility of the Fall Efficacy Scale (FES) for the prediction of falls in stroke patients. We demonstrated whether the FES can measure the standards for the screening of risk factors for falling by stroke patients. In addition, we identified the factors the affect the FES and the predictive factors of falling. Methods : The subjects included 69 inpatients with hemiparesis who can walk independently. We surveyed the number of falls and used the FES to identify their fear of falling. and conducted an evaluation on their cognitive function and depression using the Mini Mental State Examination, Korean version (MMSE-K) and Geriatric Depression Scale, Korean version (GDS-K). The assessments on their functional performance measured their activities of daily living (Modified Barthel Index; MBI), strength of their lower limbs (Sit to Stand Test; SIT), limb paresis (Fugl-Meyer Upper/Lower Extremity; FM-U/E, L/E), balance (Berg Balance Scale; BBS), and mobility (Timed Up & Go test; TUG). A receiver operation characteristic curve was utilized to investigate the optimum cutoff value of the FES on the prediction of falling, and a multiple linear regression analysis and logistic regression analysis were used to identify the main factors for FES and the prediction of falling. Results : A cut-off score of ≥14.5 on the FES was the standard value for the prediction of risk factors of falling, and <14.5 was used for those with a low incidence of falling. The most affective factors of FES were the TUG variables, and we identified that FES as a psychologic factor exists in terms of a discrimination between the falling group and non-falling group. Conclusion : FES is able to assess the self-efficacy related the fear of falling, and identify the functional performance ability. In addition, FES may be used as part of an initial assessment tool to identify the related falling risk. To comprehensively understand the related risk of falling in individual patients, further study is needed, including a quantitative analysis evaluating the patient's physical function, and should include psychologic factors.

    The Effect of EEG Changes From a Tactile Exploration and the Affected Site of a Stroke Patient

    안시내 | Kwang Kee Kim | Jeongweon Lee and 1other persons | 2013, 21(1) | pp.41~55 | number of Cited : 3
    Abstract
    Objective : This study was conducted to find the effect from the differences in EEG caused by the type of tactile exploration used and the affected site in the stroke patient. Methods : The data were collected on 21 stroke patients and 23 normal subjects between March and June of 2012. The EEG test conditions were classified as resting, passive, and active based on the type of tactile exploration. The conditions of the analyzed regions were sorted into Rt. hemiplegia, Lt. hemiplegia, and normal. We collected the data on the relative power of each patient's alpha rhythm and beta rhythm. An analysis of variance was conducted using SPSS 18.0. Results : The EEG activity differed according to the tactile exploration type and the affected site. We also found that the relative power of the alpha rhythm was lower during a passive state as compared with a resting or active state. Depending on the affected site, the relative power value of the beta rhythm was higher for the patients with a Rt. hemiplegia and the normal subjects. The interaction of each condition produced no changes. Conclusion : We found the effectiveness of the EEG value depending on the tactile exploration type used and the affected site. Accordingly, the tactile exploration method and affected site should be considered when providing occupational therapy. This study provides the related evidence for this based on neurophysiology.

    강보미 | Hyuk-Cheol Kwon | KIM HWAN and 1other persons | 2013, 21(1) | pp.57~69 | number of Cited : 13
    Abstract
    Objective : This research was conducted to determine how orofacial exercises affect the swallowing function of stroke patients. Methods : Based on the standards for subject selection, 10 patients were chosen for this study. Five subjects in the experimental group received orofacial exercises and traditional dysphagia therapy consecutively for 15minutes each. In contrast, five subjects as a control group received traditional dysphagia therapy twice in a row for 15 minutes each during every session. Therapeutic intervention was conducted five times per week for four weeks. To compare the swallowing function before and after each therapeutic intervention, the scale was scored utilizing the New Video Fluoroscopic Swallowing Study (New VFSS) scale. Moreover, the patient's tongue pressure was measured using the Iowa Oral Performance Instrument (IOPI) to compare their orofacial strength before and after the therapy. Results : The swallowing functions in both groups showed a statistically significant difference before and after intervention. All patients in the experimental group had significant differences in tongue elevation, tongue lateralization, tongue protrusion, cheek compression pressure, and lip compression pressure. The control group, however, showed significant differences in only tongue elevation. Conclusion : The orofacial exercises used in this study showed significant improvements in the swallowing functions and orofacial muscle strength of stroke patients suffering from dysphagia.

    The Relationship Between Basic Perceptual-Cognitive Function and Driving Aptitude After a Brain Injury

    Park Myoung Ok | 2013, 21(1) | pp.71~79 | number of Cited : 11
    Abstract
    Objective : The purpose of this study was to verify the relationship between the basic perceptual-cognitive function and driving aptitude after a brain injury, and to suggest the importance of the cognitive perception of training to improve driving skills. Methods : From January to September 2011, 31 brain injury patients were referred to a driving clinic at the National Rehabilitation Center. All participants were evaluated using a virtual driving simulator driving assessment, K-MMSE (Korean version-Mini Mental State Examination), and MVPT (Motor-free Visual Perception Test). Results : The total K-MMSE score showed correlations with the reaction time and steering wheel and pedal operation ability in terms of driving aptitude. In addition, the total MVPT score showed correlations with judgment, and steering wheel and pedal operation ability, in terms of driving aptitude. Conclusion : This study found that basic perceptual-cognitive function influences the driving aptitude and driving performance, and suggests the importance of perceptual-cognitive training for driving. Also, the results of this study imply that we need a cognitive-perceptual assessment tool and cognitive-perceptual training program for driving as a specialized area in domestic cognitive-rehabilitation clinics.

    Abstract
    Objective : The purpose of this study was to analyze the correlation between the practical examination of the national board for certification in occupational therapy and the work capability of inexperienced occupational therapists, and to investigate the predictive validity of the practical examination. Methods : The scores of the practical examination of the national board for certification in occupational therapy,and the work capability, were surveyed from 59 inexperienced occupational therapists in 21 clinical centers across the country. In addition, supervisors evaluated the work capability of inexperienced occupational therapists. The data was analyzed to determine the correlation between the practical examination of the national board for certification and the work capability of inexperienced occupational therapists. Results : The results showed a positive significant correlation (r=.414) between the practical examination and the work capability of inexperienced occupational therapists. The supervisors gave high scores in categories of activeness in terms of self regulation and personality. The mean total score by the supervisors was 106.29with a standard deviation of 20.17. The inexperienced occupational therapists scored 97.49 on the self test,and higher than the supervisors in terms of personality and interpersonal skills. Conclusion : The correlation was found to be significant but with a low correlation coefficient. The national examination of occupational therapists should be improved in a manner that verifies the content and reflects a real clinical situation.

    The Characteristics of QuickDASH for Workers in the Manufacturing Industry

    김장곤 | 강진우 | 2013, 21(1) | pp.107~118 | number of Cited : 3
    Abstract
    Objective : The purpose of this study was to evaluate to what extent the QuickDASH score has on manufacturing workers in a particular area in terms of managing musculoskeletal disorders among subjects with and without pain. In addition, we intended to see whether there are any differences in QuickDASH scores in terms of pain, whether any part of the score is more closely associated with musculoskeletal disorders, and whether we can distinguish people who know what the score is to a certain extent from those who don’t. Methods : A QuickDASH survey was conducted on 2,190 manufacturing production workers with upper extremity musculoskeletal symptoms only. To see any differences in the scores, their upper extremity musculoskeletal symptoms were measured using survey results from QuickDASH, an ROC analysis used to measure sensitivity and specificity. Results : There was a statistically significant difference in the QuickDASH scores of subjects with pain in their neck, shoulder, arm/elbow, and hand/finger between symptomatic and asymptomatic subjects. When a certain body area such as the neck, shoulder, arm/elbow, and hand/finger was not distinguished, in the case of subjects with symptoms in any body area, and the symptom-free subjects did not show any difference depending on the subject type even when the QuickDASH sensitivity and specificity were 77.0% and 63.5%,respectively, the number of critical points was 24.9, and AUC was .776. Conclusion : This study shows that QuickDASH can be used as an arm function assessment tool for musculoskeletal disorders of the upper extremities.

    Study on Occupational Therapists in Terms of Their Experience in Relationship Conflicts: Applied to Parse’s Human Becoming Research Methodology

    송병남 | 김슬기 | 박지훈 and 3other persons | 2013, 21(1) | pp.119~132 | number of Cited : 2
    Abstract
    Objective : This study aimed at discovering the structure of relational conflicts experienced by occupational therapists working in a clinical setting. Methods : For this study, conversations with eight occupational therapists undertaking occupational therapy in a clinical setting were carried out once or twice during February 2011. The study collected data up to a saturation point at which the stories become repetitive regarding the relational conflicts experienced by participants in a clinical setting, or when no more new contents were discovered. Data collection and analysis were conducted in accordance with the procedure of Parse’s Human Becoming Theory. Results : As a result of this research, conflicts experienced by occupational therapists were revealed to be from a lack of understanding of occupational therapy by nearby people, conflicts with nearby people such as newly appointed therapists, and an institutional system that is not favorable to occupational therapy. To solve these issues, the participants tried to solve their conflicts by proposing the effects of occupational therapy while pursuing self development. Through these efforts, they were hoping to achieve a bright future for occupational therapy. Conclusion : The conflicts experienced in a clinical setting are mostly caused by a lack of proper perception regarding occupational therapy by nearby people owing to a dissatisfactory promotion of occupational therapy. It is therefore necessary to make the effort to promote occupational therapy.
