Background:
Shirodhara is a brain relaxation therapy. The treatment induces a relaxed state with awareness that results in treating neurological conditions like mental stress (depression/anxiety/hypertension) and some of its beneficial side effects are soothing the central nervous system.
Objectives:
In the present study, the investigation aimed to analyze the ratios of brain waves, particularly focusing on the frontal region.
Materials And Methods:
In this study, Shirodhara with "Ksheerabala thailam" medicinal oil was conducted on 16 participants and pre-post treatment brain signals were collected using an EEG acquisition tool and it was found that treatment induced relaxation aspects were observed among participants.
Results And Conclusion:
Welch's Fast Fourier transform (FFT) was used to analyze the EEG signals in order to obtain power spectral density (PSD) features, which indicated a signal's power dispersed across a range of frequencies. The effectiveness of treatment has been evaluated by examining the spectral power ratios of alpha/beta, theta/beta in the frontal region of the brain and physiological and psychological parameters.
