Abstract
Background: Transcranial photobiomodulation (tPBM) enhances cognitive and emotional states. We compared continuous-wave (CW) and pulsed-wave (PW) tPBM effects on 24 healthy males.
Method: Participants received 630 nm tPBM at 95 mW/cm2 for 10 min: Sham, CW, or PW (500 Hz). Outcomes were assessed using the Karolinska Sleepiness Scale (KSS) (for measuring sleepiness), State-Trait Anxiety Inventory (STAI) (for assessing anxiety), Visual Analog Scale (VAS) (for measuring stress), and Beck Depression Inventory-II (BDI-II) (for evaluating depressive symptoms), and 32-channel EEG at baseline, treatment, and rest phases.
Results: Paired t-tests showed PW tPBM significantly improved sleepiness, anxiety, stress, and depression scores post-intervention (p < 0.05). ANOVA analyses indicated PW tPBM increased Alpha and Gamma band EEG power versus baseline (p < 0.05).
Conclusion: PW tPBM may improve cognitive and emotional outcomes and modulate brain activity, offering therapeutic insights.
