PURPOSE: This study compared the effects of computer-based and virtual reality-based cognitive rehabilitation programs on the cognitive function, upper limb function, activities of daily living, and their impact on the prefrontal cortex in convalescent stroke patients. METHODS: Ten recovering stroke patients were assessed for their cognitive function, upper limb function, and daily living activities using the Neurobehavioral Cognitive Status Examination, the Korean version of the Fugl-Meyer Assessment, and the Korean version of the Modified Barthel Index. The prefrontal cortex activity was measured with functional Near Infrared Spectroscopy. The virtual reality-based cognitive rehabilitation group utilized a program of daily living activities delivered via a laptop and Oculus Rift. The computer-based cognitive rehabilitation group performed various cognitive tasks on an all-in-one PC. Both groups underwent cognitive rehabilitation training for 30 minutes per day, three times a week, for six weeks, with identical conventional rehabilitation therapies in the hospital. RESULTS: Both programs positively impacted the cognitive and physical functions. On the other hand, the virtual reality-based cognitive rehabilitation program had a larger influence on improving the cognitive and physical functions of convalescing stroke patients. CONCLUSION: The virtual reality program suggests its potential to enhance cognitive and physical functions in convalescent stroke patients through increased engagement, focus, real-time feedback, and game elements, making it a promising rehabilitation approach.

Objective: This study was conducted to verify the effectiveness of a cognitive rehabilitation program consisting of physical exercises and mental activities for patients with chronic stroke with mild cognitive impairment (MCI). We aimed to investigate how this cognitive rehabilitation program affects patients' cognitive ability, depression, and sleep quality. Design: One group pretest-posttest design Methods: The study was conductedon 12 patients who participated in thecognitive rehabilitation complex exercise program for 16 weeks. The Korean version of the Montreal Cognitive Assessment (MoCA-K), Hamilton Depression Rating Scale (K-HDRS), and Pittsburgh Sleep Quality Index (PSQI) were used to evaluate the measured variables before and after study participation. The cognitive rehabilitation complex exercise program included 30 minutes of cognitive exercise and 30 minutes of Brill Exercise. The Wilcoxon signed-rank test was used to compare the variables before and after program participation. Cronbach's ɑ was used to assess the reliability of the test variables. Results: The post-program assessment showed a statistically significant increase in the MoCA-K score, which measures cognitive function (Z=-2.628, P=0.009). For depression ratings, there was a statistically significant decrease in the K-HDRS score (Z=-2.041, P=0.041). For sleep quality, although there was a numerical increase in the PSQI score, the difference was not statistically significant (Z=-0.702, P=0.483). The reliability test confirmed that all the individual test variables exhibited high reliability (cognitive function, 0.859; depression, 0.872; sleep, 0.822). Conclusions: We found that cognitive rehabilitation program used in this study had a positive effect on the cognitive function and depression in patients with chronic stroke with MCI.

Purpose: This study aims to investigate the effects of a group computerization cognitive rehabilitation program on cognitive function in patients with cognitive impairment. Methods: The subjects of this study comprised 34 patients with cognitive impairment (15 males and 19 females) who were randomized into two groups. The experimental group (n = 17) were trained with the group computerization cognitive rehabilitation program, while the control group (n=17) received traditional cognitive therapy. The interventions for both groups were performed for 1 hour per day, once a week for 12 weeks. The cognitive functions of the subjects before and after the experiment were measured using the Korean mini-mental state examination (K-MMSE), global deterioration scale (GDS), clinical dementia rating (CDR), and Lowenstein occupational therapy cognitive assessment (LOTCA). A paired t-test was conducted to examine the intragroup differences before and after the experiment, and ANCOVA was performed to check intergroup differences. Results: The intragroup comparison results showed that the cognitive function of the group that were trained with the group computerization cognitive rehabilitation program improved after the experiment more than for the group that received traditional cognitive therapy. The intergroup comparison results showed significant differences in orientation, visual perception, and visuomotor organization between the two groups. Conclusion: The results of this study confirmed that the group computerization cognitive rehabilitation program was more effective in improving cognitive function than the traditional cognitive therapy in patients with cognitive impairment. Based on the results of this study, the group computerization cognitive rehabilitation program can be used as an effective intervention method for patients with cognitive impairment.

Objective : The purpose of this study was to investigate parental perspectives on cognitive rehabilitation using a combination of phenomenological research methodology and word cloud analysis. Methods : Interviews were conducted with five parents of children with developmental disabilities. Word cloud analysis was conducted using Python, and five researchers analyzed the meaning units and themes using phenomenological methods. Words with high frequency were considered as a heuristic tool. Results : A total of 43 meaning units and nine components related to the phenomenon of cognitive rehabilitation were derived, and three themes were finalized. The main themes encompassed the definition of cognitive rehabilitation, challenges associated with cognitive rehabilitation, and factors influencing the selection of a cognitive rehabilitation institute. Cognitive rehabilitation emerged as a treatment focused on improving learning, daily functioning, and cognitive abilities in children with developmental disabilities. The perceived issues with cognitive rehabilitation pertained to treatment methods, therapist expertise, and associated costs. In addition, parents highlighted the importance of therapist expertise, humane personality, and affordability of cost and schedule when choosing a cognitive rehabilitation institute. Conclusion : Parents expressed expectations for substantial improvements in their children's daily functioning through cognitive rehabilitation. However, challenges were identified in clinical practices. Going forward, we expect that cognitive rehabilitation will evolve into a better therapeutic support service addressing the concerns raised by parents.

This paper describes the effect of a robot cognitive rehabilitation program on cognitive functions for the elderly with mild cognitive impairment, and compares it with traditional cognitive therapy programs. Three experiment groups including cognition therapy group, robot cognitive rehabilitation group, and hybrid group have been sampled and one comparative group has been organized for this research. 32 old people whose ages are between 61 and 88 with mild cognitive impairment participated in the programs with an admission of W care hospital. According to the program results, the cognitive therapy program alone had shown a positive effect on the attention function, and the robot cognitive rehabilitation program alone had a positive effect on the total intelligence and memory function. However, a simultaneous operation with both programs had shown a positive effect on the three intelligence areas such as total, basic, and management quotients as well as attention and memory functions as subsidiary factors. This paper has verified that the proposed robot cognitive rehabilitation program makes a positive effect on a cognitive function and plays a complementary role with traditional cognitive therapy programs.

Purpose : This study aimed to investigate a study on the intervention of computerized cognitive rehabilitation applied to patients with dementia in Korea. Thus, a systematic discussion was conducted. Methods : Studies from January 2000 to December 2016 were searched in the Korea Education and Research Information Service. The main key words used were: "dementia," "computerized cognitive rehabilitation," "computerized cognitive training," "computer assisted cognitive therapy," and "computerized cognitive therapy." Result : A total of five studies were selected. The effects of the computerized cognitive rehabilitation therapy applied to patients with dementia resulted in improved cognitive functions, as well as daily living and activities instrumental to daily living. There was also an increase in brain activity. The qualitative aspects of this study showed a low level of internal and external validities due to the small number of subjects, short period of intervention, and limited study environment. Conclusion : In the future, it is necessary to continue a study in which the level of evidence is high to determine whether various cognitive rehabilitation programs are effectively applied to patients with dementia.

Among the elderly and patients with mild brain diseases (such as dementia and stroke), when there is a certain degree of self-acting ability and cognitive ability, exercise and cognitive rehabilitation are often required. However, since most of the existing rehabilitation systems are separated or specialized in exercise or cognitive rehabilitation, there is a need for a form linking both. In this paper, we propose a game-type rehabilitation system that enables both exercise and cognitive rehabilitation using CAN communication protocol, one of ICT technologies. This system uses the CAN BUS structure to separate and combine each individual module constituting the rehabilitation system in various forms. A prototype of the proposed system was actually produced to show that various types of rehabilitation environments can be implemented according to the degree of cognitive ability and motor ability of the patient (or the elderly). In addition, through several experiments using this system, it is possible to implement exercise/cognitive parallel rehabilitation applicable to various environments.

Purpose : The purpose of this randomized controlled trial study was to examine the effect of transcranial direct current stimulation (tDCS) on cognitive function and depression in stroke patients. Methods : Thirty stroke patients were randomly divided into an experimental group (n = 15) and a control group (n = 15). The experimental group received tDCS while performing computerized cognitive rehabilitation programs, and the control group was provided with sham tDCS while operating the same programs. The 30-minute intervention was implemented five times per week for six weeks. To assess cognitive function before and after the intervention, the Neurobehavioral Cognitive Status Examination was conducted; the Beck Depression Inventory BDI was employed to assess depression. Results : The experimental group showed statistically significant increases in cognitive function and decreases in depression (p < .05 ). Comparing the amount of variation between the groups after arbitration also showed significant differences in cognitive function and depression between the two groups (p > .05). Conclusion : The application of tDCS and computerized cognitive rehabilitation programs for stroke patients may positively affect their cognitive function and depression. Therefore, tDCS used with computerized cognitive rehabilitation programs is positively applicable to the enhancement of cognitive function in stroke patients and reduction of depression.

The cognitive rehabilitation training is important for treating many cognitive impairment conditions, including Parkinson's disease, stroke, and ADHD. In this study, we developed a new evaluation system to improve the measurement of the conventional evaluation systems for cognitive rehabilitation training. The developed system measured the activity of dopamine(DA) and an autonomic nervous system(ANS) with photoplethysmography and electromyography. The results demonstrated that the cognitive capacity was increased but the activity of DA was decreased with unbalanced ANS by short-term stress. Based on the results, the effect of short-term stress should be recognized for the cognitive rehabilitation training.

Purpose: The purpose of this study was to test the effectiveness of a cognitive rehabilitation program for the patients having an acute stroke. The variables evaluated were cognitive function, depression and activities of daily living (ADLs). Methods: A non-equivalent control group pretest-posttest design with sixty-two subjects from two separated institutions was the design for the study. Thirty-three patients were assigned to the treatment group and 29 patients comprised the comparison group. The treatment group participated in the nursing intervention for cognitive rehabilitation for a three week period of time. The study was conducted from September 2010 to April 2011. Results: Following the three week intervention, the cognitive function and activities of daily living of the treatment group were significantly improved compared to the comparison group (t=6.33, p<.001; t=4.57, p<.001). Specifically, depression was significantly decreased in the treatment group (t=3.95, p<.001). Conclusion: The cognitive rehabilitation program was effective in increasing the treatment group cognitive function and activities of daily living along with a decrease in depression scores. Therefore, Cognitive Rehabilitation Program could be expected a beneficial nursing intervention in stroke patients.
