Summary
AI-generated from the abstractIn young novice students, four months of Preksha meditation training led to a statistically significant increase in alpha wave frequency on EEG, rising from 49.52% at baseline to 66.59% after four months. No significant change was observed after two months. The control group showed no significant change over the same period. The findings suggest that longer meditation practice is needed to produce measurable improvements in alpha wave activity.

Abstract
Aims: The present study aims at demonstrating changes in alpha wave frequency on electroencephalograph (EEG) at two and four months of preksha meditation training in young novice students. Materials and Methods: Participants included 52 girls between the 17 to 21 years of age from a local college selected using a convenience sampling technique. They were randomly divided into experimental (n = 29) and control (n = 26) groups. Study duration was 4 months during which experimental group was administered a supervised PM training for 4 months. During this period control group continued their normal activities without mediation practice. EEG was analyzed for alpha waves and compared at base line, at 2 months and at 4 months. Results: The mean value of alpha wave frequency (%) in control group at beginning was 49.65 ±21.598 which increased to 52.58±18.005 at 2 months. In experimental group, in beginning it was 49.52 ±18.169 which increased to 54.31±22.490 at 2 months. However, this increment was not statistically significant in both groups. A statistically significant increment in alpha waves percentage to 66.59±9.493 was observed in experimental group after four months of PM which was significant at the level of p Conclusions: A significant increase in alpha waves was observed at 4 months of PM practice in young novice students. This increase was observed at 4 months and not at 2 months suggesting that longer practice of meditation is needed to bring out significant improvement. Keywords: Preksha meditation, EEG, Alpha waves.
