EEG Spectral Analysis on Muslim Prayers

This study investigated the proposition of relaxation offered by performing the Muslim prayers by measuring the alpha brain activity in the frontal (F3-F4), central (C3-C4), parietal (P3-P4), and occipital (O1-O2) electrode placements using the International 10-20 System. Nine Muslim subjects were asked to perform the four required cycles of movements of Dhuha prayer, and the EEG were subsequently recorded with open eyes under three conditions, namely, resting, performing four cycles of prayer while reciting the specific verses and supplications, and performing four cycles of acted salat condition (prayer movements without any recitations). Analysis of variance (ANOVA) tests revealed that there were no significant difference in the mean alpha relative power (RP(α)) between the alpha amplitude in the Dhuha prayer and the acted conditions in all eight electrode positions. However, the mean RP(α) showed higher alpha amplitude during the prostration position of the Dhuha prayer and acted condition at the parietal and occipital regions in comparison to the resting condition. Findings were similar to other studies documenting increased alpha amplitude in parietal and occipital regions during meditation and mental concentration. The incidence of increased alpha amplitude suggested parasympathetic activation, thus indicating a state of relaxation. Subsequent studies are needed to delineate the role of mental concentration, and eye focus, on alpha wave amplitude while performing worshipping acts

Assessment of heart rates and blood pressure in different Salat positions

Purpose This study reports the effects of the Muslim prayer, known as Salat, on heart rate (HR) and blood pressure (BP) while performing and miming the actions of Salat: standing, bowing, prostrating and sitting. Subjects Thirty Muslim subjects were asked to perform the actual and mime Salat. Methods HR and BP were measured using a Schiller AT-102 Electrocardiograph and an Omron SEM-1 Automatic Blood Pressure Monitor. Results The findings revealed that there was a significant difference in the HR of the subjects between performing and miming Salat. The standing and prostration positions of Salat produced the highest and the lowest HR, respectively. A lower HR may be of potential benefit to an individual's health. The systolic and the diastolic BP decreased significantly after performance and mime of Salat, and a greater reduction in BP was observed during performance of Salat. Conclusion This is the first study of HR and BP in relation to Salat positions. The findings will encourage further studies to explore the benefits of Salat maneuvers for patients with cardiovascular diseases

Adaptive neuro-fuzzy inference system for predicting alpha band power of EEG during muslim prayer (SALAT)

The features of electroencephalographic (EEG) signals include important information about the function of the brain. One of the most common EEG signal features is alpha wave, which is indicative of relaxation or mental inactivity. Until now, the analysis and the feature extraction procedures of these signals have not been well developed. This study presents a new approach based on an adaptive neuro-fuzzy inference system (ANFIS) for extracting and predicting the alpha power band of EEG signals during Muslim prayer (Salat). Proposed models can acquire information related to the alpha power variations during Salat from other physiological parameters such as heart rate variability (HRV) components, heart rate (HR), and respiration rate (RSP). The models were developed by systematically optimizing the initial ANFIS model parameters. Receiver operating characteristic (ROC) curves were performed to evaluate the performance of the optimized ANFIS models. Overall prediction accuracy of the proposed models were achieved of 94.39%, 92.89%, 93.62%, and 94.31% for the alpha power of electrodes positions at O1, O2, P3, and P4, respectively. These models demonstrated many advantages, including efficiency, accuracy, and simplicity. Thus, ANFIS could be considered as a suitable tool for dealing with complex and nonlinear prediction problems
