背景:这项研究旨在研究神经反馈训练(NFT)对定量脑电图(QEEG)中α活性的影响,认知功能,以及老年性耳聋患者的言语感知。
方法:本研究于2020年6月15日至11月30日进行。实验组(n=28)行NFT,而对照组(n=31)被指示继续他们的常规日常生活。NFT进行了40分钟,一周两次,共16个疗程,使用NeurocharmonyS和BrainHealth2.7进行.使用QEEG将α活性测量为α波。使用韩国版的迷你精神状态检查来测量认知功能,数字跨度向前和向后(DSF和DSB)。使用带有韩国标准成人单音节单词列表的听力计,使用单词和句子识别得分(WRS和SRS)测量语音感知。
结果:实验组表现出左额叶α波的改善,测量为α活性(t=-2.521,p=0.018);MMSE-K(t=-3.467,p<.01),和DSF(t=-2.646,p<.05)作为认知功能测量;和WRS(t=-3.255,p=.003),与对照组相比,SRS(t=-2.851,p=0.008)测量为语音感知。
结论:这项研究表明,NFT可以被认为是一种有效的基于大脑和认知科学的认知和听觉康复方法,用于改善α活性。认知功能,和言语感知。
BACKGROUND: This study aimed to investigate the effects of neurofeedback training (NFT) on alpha activity in quantitative electroencephalography (QEEG), cognitive function, and speech perception in elderly with presbycusis.
METHODS: This study was conducted from June 15 to November 30, 2020. The experimental group (n = 28) underwent NFT, while the control group (n = 31) was instructed to continue with their routine daily life. The NFT conducted for 40 min, two times a week, for a total of 16 sessions and was performed using Neuroharmony S and BrainHealth 2.7. The alpha activity was measured as alpha waves using QEEG. The cognitive function was measured using the Korean version of Mini-Mental Status Examination, digit span forward and backward (DSF and DSB). The speech perception was measured using the word and sentence recognition score (WRS and SRS) using an audiometer with the Korean Standard Monosyllabic Word Lists for Adults.
RESULTS: The experimental group demonstrated improvement in the alpha wave of the left frontal lobe measured as alpha activity (t=-2.521, p = .018); MMSE-K (t=-3.467, p < .01), and DSF (t=-2.646, p < .05) measured as cognitive function; and WRS (t=-3.255, p = .003), and SRS (t=-2.851, p = .008) measured as speech perception compared to the control group.
CONCLUSIONS: This study suggests that NFT could be considered an effective cognitive and auditory rehabilitation method based on brain and cognitive science for improving alpha activity, cognitive function, and speech perception.
