摘要

本研究目的在瞭解穴位電刺激是否能對注意力網絡功能產生影響進而提升注意力。研究招募60位研究參與者，隨機分派至穴位電刺激及偽刺激組。以多頻道銀錘點低周波治療儀在雙手合谷及內關穴進行電及偽電刺激。以注意力網絡測驗為評估工具，取得前測、中測及後測警覺性、導向性、執行控制功能分數，以混合設計二因子變異數分析統計檢定。結果顯示，穴位電刺激與偽刺激組組間注意力網絡功能未達顯著差異；但在警覺性功能中不同測量時段呈現顯著差異，穴位電刺激組警覺性功能前測低於中測、後測，偽刺激組警覺性功能前測低於中測，與後測無顯著差異。穴位電刺激與偽刺激組間未能呈現顯著差異，可能來自刺激劑量不足，未來若以療程方式累積劑量或能產生較大效果。穴位電刺激造成警覺性功能增加且能延續15分鐘，但對於警覺性的提升，來自穴位特異性或單純電刺激效果需更進一步證實。偽刺激當下警覺性顯著提升但無法延續至後測階段，可能與偽刺激當下的穴位按壓效果有關。

This study aims to explore the effect of electro-acustimulation (EA) on attention networks. Sixty participants were randomly divided into EA and sham-EA group. The acupoints LI-4 (HeGu) and PC-6 (NeiGuan) were stimulated by transcutaneous electrical nerve stimulator. Attention network test (ANT) was employed at pre-test, test and post-test phases. Mixed two-factor ANOVA was conducted. Results showed no significant difference between EA and sham-EA in ANT. The alerting function within group at three phases showed statistically significant differences. The level of alerting function at pre-test was lower than during and post-test phases in EA while it was lower than during-test phases only in sham-EA. The non-significant difference between EA and sham-EA in ANT might be due to insufficient doses of stimulation. Whether the enhancement of alerting function in EA comes from the specificity of acupoint selection or electrical stimulation effect requires further confirm. The improvement of alerting function at the during-test phase in sham-EA group might be related to the pressing effect on acupoints.
