Abstract:
Introduction: The brain waves pattern in primary insomniacs is different from healthy subjects. Studies have shown that binaural beats can alter the pattern of brain waves in healthy individuals; however, the efficacy of binaural beats in altering the pattern of brain waves in primary insomniacs has not yet been investigated. This study aims to evaluate the efficacy of theta binaural beat on the absolute power of theta activity in primary insomniacs.
Methods: This study was a randomized clinical trial with experimental and control groups. The primary insomniacs received theta binaural beats in the experimental group while the control group received white noise. Their brain waves were recorded by electroencephalogram for 25 min; the first 5 min was without stimulus (first block), the next was followed by 15 min of receiving stimulus (binaural beat or white noise), and the last 5 min without stimulus (fifth block). The Matlab software, version R2019a, EEGLAB toolbox, and SPSS software, version 24 were used to analyze the data.
Results: The absolute power of theta activity in the experimental group was significantly higher in the last block compared to the first block in all brain lobes (P<0.05). The largest changes in theta activity were in the temporal and parietal lobes, and the last one was in the prefrontal lobe. In the control group, none of the brain lobes showed significant differences in the last block compared to the first block.
Conclusion: Theta binaural beat can alter the absolute power of theta activity in primary insomniacs. The implications of the study are discussed.
