ABSTRACT

[Purpose] The purpose of this study was conducted to investigate a comprehensive summary of previous research on the efficacy of combined cognitive and physical exercise intervention for people with neurogenic communication disorders. For this purpose, finding out what kind of effect it has on cognitive and motor skills in Korea, it hopefully would present research trends to present fundamental data that can suggest an intervention method in the future. [Method] To grasp its analytical study on research trends, it tracked and narrowly sorted out a total of 24 papers published in the journals from 2011 to 2020, which surfaced mainly by search engines to choose to analyze. [Results] First, ever since starting with two studies reported on the initial stage in 2011, the research peaked in 2015 with the largest number of research conducted and has been carried out until then in 2020. Second, as the yardstick to evaluate the cognitive and motor skills, the mini-mental state examination (MMSE) was used the most frequently to measure changes of the cognition-focused intervention program, and next came the activities of daily living (ADL) and geriatric depression scale (GDS). In the case of physical activity arbitration programs, the MMSE, amyloid-beta (Aβ), and brain-derived neurotrophic factor (BDNF) were used to identify the changes. Third, in terms of the aspect of the intervention methods, during the cognitive-based intervention process, computer cognitive training programs and complex cognitive rehabilitation programs were most commonly used, and so were cognitive stimulation therapy, reality sensation, and time difference recollection interventions. However, in the processing stage of the physical activity intervention, the physical-based exercise program was the most effectively used, as well as the under-water exercises, parallel studies conducted with physical and cognitive activities, and virtual reality (VR) exercises and recreation programs also took part. Forth, the cognitive function improved in light of the efficacy of intervention as the most significant change. The ADL, the quality of life, and social interaction made positive progress during the cognitive-based intervening process as well. The most remarkable effect while the physical exercise intervention demonstrated was the improvement of cognitive functioning, followed by Aβ, BDNF, physical performance, the quality of life, depression, brain activities, the hand function. [Conclusion] Rather than mediating cognitive and physical activity intervention separately, it assumes more effective to apply both cognitive and physical activities in parallel, and further research will very likely require the development of an intervention program systematically established by incorporating the two methods of intervention.
