Purpose: This study aimed to examine the immediate effects of yoga nidra on relative theta power and sensorimotor rhythm (SMR) in patients with stroke. Methods: This study employed a single-group pretest-posttest design; data from 14 patients with stroke were analyzed. Electroencephalography (EEG) was recorded before and immediately after a single session of yoga nidra. Relative theta power and relative SMR were calculated from EEG signals. Pre- and post-intervention values were compared using paired t-tests or the Wilcoxon signed-rank test, as determined by normality assessment. False discovery rate (FDR) correction was applied to adjust for multiple comparisons, and effect sizes were calculated. Statistical significance was set at α = .05. Results: Relative theta power showed no statistically significant differences across all electrodes either before or after FDR correction. Relative SMR showed a significant decrease only at the Fp1 electrode before correction (p = .034), with a moderate effect size (Cohen’s dz = .632). However, this finding did not survive FDR correction (adjusted p = .646). Conclusion: A single session of yoga nidra did not produce statistically significant changes in relative theta power or relative SMR following correction for multiple comparisons in patients with stroke. Although a pre-correction decrease in relative SMR was observed at Fp1, this finding should be interpreted with caution. These results may provide pilot data for future EEG-based studies examining the effects of yoga nidra in patients with stroke.
