Abstract
Background: Investigation of alpha wave power has been carried out in many previous studies. However, the database on alpha wave power in Vietnamese adults is still limited. Therefore, the aim of this study is to investigate the characteristics of alpha wave power in the parietal and occipital regions and some related factors in Vietnamese adults.
Materials and method: A cross-sectional and descriptive study was conducted on 100 subjects collected at the Department of Functional Diagnosis, Military Hospital 103 from June to December 2023.
Results: The average alpha wave power values for the left and right occipital regions of the hemisphere were 49.7 µV2 and 41.2 µV2 in the eyes-closed state and 27.6 µV2 and 25.9 µV2 in the eyes-open state and for the the left and right parietal regions were 30.5 µV2 and 25.5 µV2 in the eyes-closed state and 21.5 µV2 and 21.0 µV2 in the eyes-open state, respectively. Age is negatively correlated, and smoking and drinking alcohol showed decrease in left hemisphere occipital alpha wave power in the eyes-closed state. Height was positively correlated with alpha power in the right occipital region in the eyes-open state.
Conclusion: these results show that the highest alpha wave power value is recorded in the occipital region in the closed eye state. Age, smoking, alcohol consumption, and height are factors that influence the alpha wave power.
