Increased availability of smartphones and easy access to the internet among adolescents has resulted in Internet Addiction (IA). Effects of IA and Pranayama on evoked potential are available but studies on the comparison of immediate and 6-week effects of alternate nostril breathing on evoked potentials among medicos with internet addiction are not available as per our search in PubMed, hence the study was chosen. In this comparative study 100 male and female medical students aged between 18-25 years, with internet addiction scores ≥ 50 were included as study participants. P300 auditory event-related potential and pattern reversal visual evoked potential (VEP) were recorded before, immediately, and 6 weeks after practicing pranayama. Repeated measure ANOVA shows statistically significant change (P<0.05) in P300 amplitude, P100 latency, N145 latency, and VEP amplitude. The post hoc Bonferroni test shows that P100 latency and N145 latency significantly reduced immediately after 15 minutes of pranayama. P300 amplitude and VEP amplitude significantly increased only after practicing pranayama for 6 weeks. Pranayama has an immediate effect on latency, but it takes 6 weeks of practice to significantly change amplitude.
青少年智能手机的普及以及互联网的便捷接入导致了网络成瘾（IA）。网络成瘾和调息法对诱发电位的影响已有相关研究，但根据我们在PubMed上的检索，尚无关于交替鼻孔呼吸对有网络成瘾的医科学生诱发电位的即时和6周效果比较的研究，因此选择了本研究。在这项比较研究中，100名年龄在18 - 25岁、网络成瘾得分≥50的男女医科学生被纳入研究参与者。在练习调息法之前、之后立即以及6周后记录P300听觉事件相关电位和图形翻转视觉诱发电位（VEP）。重复测量方差分析显示P300波幅、P100潜伏期、N145潜伏期和VEP波幅有统计学上的显著变化（P<0.05）。事后邦费罗尼检验表明，调息法练习15分钟后，P100潜伏期和N145潜伏期立即显著缩短。仅在练习调息法6周后，P300波幅和VEP波幅才显著增加。调息法对潜伏期有即时影响，但需要6周的练习才能显著改变波幅。
