This study was done objected to the chronic stroke patients in order to evaluate change in brain wave activity and cognitive performance when Neurofeedback training. The subjects were over 6 months ago in chronic stroke patients screened-test through the 20 patients, 10 persons in each group were randomly placed. This was carried out in 4 weeks in total, with control group(n=10) on general physical therapy and experimental group(n=10) on general physical therapy along with Neurofeedback training. The general physical therapy was applied 5 times a week, 30 minutes at once, Neurofeedback training was applied as equally as the general physical therapy, which makes 20 times in total. To learn about the effect before the training, after training, and 2 weeks after the training in electric physiological measurement method of the brain, electroencephalogram(EEG) to examine challenges by calculating the absolute spectrum power for standard EEG change(%), followed by evaluation with clinical assessment tool MMSE-K, Stroop Test, Digit Span Test. As a result of comparing the change in brain wave through EEG, after training and 2 weeks after training showed that absolute α-power and absolute β-SMR power of experimental group have increased and absolute θ-power decreased significantly compared to experimental group I. Moreover, the MMSE-K score in trial appraisal has increased significantly, and the error in Stroop Test and Digit Span Test has decreased significantly. such results, with the chronic stroke patient's brain wave control, Neurofeedback training was determined to improve the cognitive performance. this study suggests a new training possibility of stroke patients by identifying the training effects of Neurofeedback training that trains the brain directly with brain wave control.
The purpose of this study is to identify functional characteristics of heart and blood expression of vascular regulators during rest and GXT (grade exercise test) in elite runners. For this purpose, long distance runners (LDG, n=9) and health male college students (CON, n=9) were participated in this study voluntarily. Body compositions were measured by In-Body 4.0(Bio space, Korea), Bruce protocol were used to GXT with treadmill (Quinton Co. USA) and all parameter were measured during rest and GXT. Heart rate was measured by polar and blood pressure was measured by mercury sphygmomanometer. The results are as follows; RPP were significantly lower in LDG compared to CON whereas PP and MAP were no significantly. Blood expression of NOS after 1 hour recovery were increased in LDG compared to CON. These results were suggested that i) because of the effects of selected factors to heart function were various by capacity of exercise, participating events and environments, if we select some method to test athletes, previously recommending methods to identify clinical condition of cardiovascular system (CVS) for non-athletes should be assortatively chosen, ii) we should to recognize differences of CVS between athletes and non-athletes, and specific protocol is needed to health ageing of athletes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
