  • PURPOSE: This study examined the effects of kinesio taping of tibialis anterior combined with cognitive dual-task training on balance and gait ability in post-stroke patients. METHODS: This study was a single-blinded, randomized control design. Thirty post-stroke patients were allocated randomly to two groups: 1) kinesio taping of tibialis anterior combined with cognitive dual-task training (KTCDT group, n = 15) and cognitive dual-task training (Control group, n = 15). Both groups were given training for 30 minutes, five days a week for four weeks. The Berg balance test and timed up-and-go test were used to measure the balance ability. GaitRite was used to analyze the gait ability. RESULTS: Both groups showed significant improvements in balance and gait ability. The KTCDT group showed significantly greater improvement in balance ability after four weeks than the control group (p < .05). In addition, the KTCDT group showed significantly greater improvement in gait ability after four weeks compared to the control group (p < .05). CONCLUSION: Kinesio taping of the tibialis anterior combined with cognitive dual-task training effectively improves the balance and gait abilities in post-stroke patients.

  • The purpose of this research was to identify expertise in ait traffic control by using cognitive skill analysis for novices and experts in routine and non-routine situations. The result of study was to understand expertise in air traffic control tasks in terms of what cognitive processes are responsible for the expert's high performance levels. The problem solving task was difficult for novices, but performed relatively automatically by experts in a routine situation. The difficulty could indicate the presence of controlled processing. Rather than rules and strategies, novices focused more on environmental factors, which merely increase cognitive load. In a non-routine situation, novices showed that they did not categorize the information consistently and alternative resources were not available for them. Experts, however, performed automatically a task by arranging and organizing information related to problem solving components in contexts without regard to a routine and non-routine situation. Especially experts developed a stable representation and directed alternative resources for air traffic flow and efficiency. Based on the results, cognitive processes of experts could be useful to understand expert performance and analyze the learning process, which imply the necessity of developing expertise systematically.

  • Purpose : This study investigates the effects of the application of traditional occupational therapy and the korean computerized cognition training system on the cognitive function and performance of daily activities of stroke patients with cognitive impairment. Methods : From inpatients referred for rehabilitation treatment at L Rehabilitation Hospital located in Busan, 20 patients diagnosed with stroke from April 05. 2021 to May 02. 2021 (study period) were selected, They were divided into two, an experimental group consisting of 10 subjects who underwent a computerized cognitive rehabilitation program and traditional occupational therapy in combination and a control group of 10 subjects who underwent traditional occupational therapy alone. In order to measure the cognitive function of the subjects before the intervention, two assessment tests were conducted: a Neurobehavioral Cognitive Status Examination (NCSE), which evaluates stroke-related cognitive ability, and a Functional Independence Measure (FIM) test, which evaluates life activities. Then, both groups received a total of 20 training sessions at 30 minutes per session, five times a week for four weeks. Results : A statistically significant difference was found in cognitive function between before and after the cognitive training for both the experimental group and the control group. For the FIM scores, statistically significant differences were observed after intervention in the categories of handling personal matters and social cognition, and in the total score. The average scores of the remaining items also improved. Conclusion : The results of this study showed that both the computerized cognition rehabilitation program and the traditional occupational therapy had a positive effect on the improvement of cognitive function in stroke patients.

  • Background: Cognitive impairment is a public health burden. Our objective was to investigate associations between work hours and cognitive function. Methods: Multi-Ethnic Study of Atherosclerosis (MESA) participants (n = 2,497; 50.7% men; age range 44-84 years) reported hours per week worked in all jobs in Exams 1 (2000-2002), 2 (2002-2004), 3 (2004-2005), and 5 (2010-2011). Cognitive function was assessed (Exam 5) using the Cognitive Abilities Screening Instrument (version 2), a measure of global cognitive functioning; the Digit Symbol Coding, a measure of processing speed; and the Digit Span test, a measure of attention and working memory. We used a prospective approach and linear regression to assess associations for every 10 hours of work. Results: Among all participants, associations of hours worked with cognitive function of any type were not statistically significant. In occupation-stratified analyses (interaction p = 0.051), longer work hours were associated with poorer global cognitive function among Sales/Office and blue-collar workers, after adjustment for age, sex, physical activity, body mass index, race/ethnicity, educational level, annual income, history of heart attack, diabetes, apolipoprotein E-epsilon 4 allele (ApoE4) status, birth-place, number of years in the United States, language spoken at MESA Exam 1, and work hours at Exam 5 (β = -0.55, 95% CI = -0.99, -0.09) and (β = -0.80, -1.51, -0.09), respectively. In occupation-stratified analyses (interaction p = 0.040), we also observed an inverse association with processing speed among blue-collar workers (adjusted β = -0.80, -1.52, -0.07). Sex, race/ethnicity, and ApoE4 did not significantly modify associations between work hours and cognitive function. Conclusion: Weak inverse associations were observed between work hours and cognitive function among Sales/Office and blue-collar workers.

  • This study was done to explore the effects of dance therapy on pulmonary and cognitive functions in the elderly. The design of this study was a non-equivalent pre-post test experiment. The subjects consisted of elderly persons living in a facility located in Kyoungi-Do. Fifty eight subjects had normal cognition, sensory function and resting blood pressure. They underwent tests of pulmonary and cognitive function as baseline data before dance therapy, and at 6th week and at the end of 12nd week after following dance therapy. Twenty seven elderly persons were assigned to the experimental group and participated with the dance therapy. This therapy was based on the Marian Chace's dance therapy and Korean traditional dance with music. The dance therapy consisted of 50 minutes session, 3 times a week for 12 weeks. One session consisted of warming-up, expression, catharsis, sharing and closing stage. the intensity of the dance therapy was at the 40% of age-adjusted maximum heart rates. Data were analyzed with mean, standard deviation, Chi-square test, unpaired t-test, repeated measures ANOVA, and Bonferroni multiple regression using SAS program. The results were as follows : 1. Pulmonary function(forced expiratory volume at one second and forced vital capacity) of the experimental subjects significantly increased over time more than that of the control subjects. 2. The experimental group had significantly higher score for pulmonary function than the control group at the 12nd week after dance therapy. 3. Cognitive function of the experimental subjects significantly increased over time more than that of the control subjects. 4. The experimental group had significantly higher score for cognitive function than the control group at the 6th week and 12nd week after dance therapy. The findings showed the dance therapy could be effective in improving the pulmonary and cognitive function of the elderly.

  • Objectives:The purpose of this study was to develop a cognitive rehabilitation program and to investigate the effect of the program that restores the deficiency of memory, which is necessary to operate on high cognitive function such as problem-solving or judgement, for TBI(traumatic brain injury) patients. Methods:Sixteen TBI patients participated in this study. The inclusion criteria were : 1) aged 18 to 60 ; 2) higher than IQ 80 ; 3) lower than MMSE-K 25 and K-MAS(Korean version of Memory Assessment Scale) 85. We administered our program to an experimental group(N=8) in order to improve attention and memory for 4 weeks(total 12 section). Our program was not administrated to a control group(N=8) for 4 weeks. After administrating this program, we measured MMSE-K and K-MAS for the experimental and control groups. Results:The findings of the study were as follows. 1) the experimental group showed significant improvement on MMSE-K score in comparison with baseline, but the control group did not. 2) the experimental group showed significant improvement on K-MAS score in comparison with baseline, but the control group did not. In particular, among the three subscales of K-MAS, only verbal memory scale revealed significant improvement, while visual and short-term memory scales revealed no differences. Conclusion:Our cognitive rehabilitation program improves cognitive state and memory, particulary verbal memory, for TBI patients. These results imply that our program aids in rehabilitation of basic cognition such as memory which is necessary to operate on high cognitive function such as problem-solving or judgement, for TBI(traumatic brain injury) patients.

  • Background: This study investigated the effects of acupuncture at Sobu (HT8) and Haenggan (LR2) on scopolamine-induced, cognitively impaired rats. Methods: Scopolamine-treated Sprague-Dawley rats were divided into 6 groups; normal, control, HT8, LR2, HT8 + LR2 and sham group. Cognitive impairment was induced by scopolamine, in control, and then in HT8, LR2, HT8 + LR2 and sham groups. Acupuncture treatment was performed at HT8, LR2, HT8 + LR2, and a random acupoint, respectively, every other day for 2 weeks. After each treatment, behavior change was observed and the rats were sacrificed. The change in brain-derived neurotrophic factor, glutathione peroxidase, and superoxide dismutase activity was evaluated by polymerase chain reaction. Results: Latency time to target in Morris Water-Maze test for the HT8 + LR2 group showed a significant decrease compared with control (p<0.05). Target crossing times and time zone ratios in Morris Water-Maze test for HT8 + LR2 group showed a significant increase compared with control (p<0.01). In the Y-Maze test the HT8 + LR2 group showed a significant increase compared with control (p<0.05). Brain-derived neurotrophic factor, glutathione peroxidase, and superoxide dismutase, in the HT8 + LR2 group, showed a significantly increased level compared with control (p<0.05). Neural activity of acetylcholine esterase in HT8 + LR2 group showed a significant decrease compared with the control group (p<0.01), choline acetyltransferase activity in the HT8 + LR2 group showed a significant increase compared with control (p<0.05). Conclusion: Acupuncture at HT8 + LR2 restored scopolamine-induced cognitive impairment, suggesting acupuncture could be an alternative to improve cognitive function.

  • Context : Oriental medicine deals with mind cardinally and effectiveness of CBT on weight control is well-known. but there is no well-structured psychotherapy for weight control like CBT in Oriental medicine so far. Therefore It is necessary to develop new cognitive program based on the theory of Oriental medical. Objective: This study examined whether Yangsung program based on new cognitive weight regulation model is effective on weight loss, self esteem and self control. Design and setting: 44 women were assigned randomly to 2 groups; experimental group(n=24) and control group(n=10). experimental group had 11 sessions consisted of cognitive therapy, meditation, general diet and exercise education. Control group had personal interview with general diet and exercise education and ear acupuncture once a week for two months. All subjects were weighed and evaluated with Rosenberg self esteem scale, and three factor eating questionnaires at the beginning of the program and at the end of the program. Result: Experimental group reported significant changes of weight, self esteem, restraint eating, disinhibition and hunger(p<0.01). Compared with control group, more significant(p<0.05) Weight reduction and self-esteem enhancement were reported in experimental group than control group. There is no significant difference between two groups in changes of restraint eating, disinhibition and hunger.
