手指輕敲測驗表現與心率變異性在健康個體之相關性研究：初步試驗結果

The Correlation Study of Finger Tapping Test Performance and Heart Rate Variability in Healthy Individuals - A Preliminary Finding

目的：與心率變異有關的中樞神經機制可能與動作控制有關，但是心率變異與精細動作表現之關聯性尚不明確。方法：短時間記錄32位健康個體的心率，並進行頻譜分析。精細動作表現採用手指輕敲測驗進行。結果：左手的手指輕敲測驗表現與高頻功率呈現顯著的負相關（r = -0.36，p ＜ 0.05），而與低頻功率呈現顯著的正相關（r = 0.36，p ＜ 0.05）。結論：精細動作表現較佳者，有可能交感神經活性較強。

Objectives: The underlying mechanism of heart rate variability (HRV) of the central nerves system is related with motor control. But, little is known for the association between the HRV and fine motor performance. Method: The HRV of 32 healthy participants was measured using a short-term recorder, and spectrum analysis was conducted for their fine motor performance using finger tapping test. Results: The study findings showed that the finger tapping test on the left hand was significantly related to the higher level of low frequency component (r = 0.36, p ＜ 0.05), and significantly related to the lower level of higher frequency component (r = -0.36, p ＜ 0.05) of HRV. Conclusion: Elevated sympathetic tone could be related with better fine motor response among health individuals.
