以心率變異性探討注意力不全過動兒體質

Heart Rate Variability Analysis of Acupuncture on ADHD Children

目的：藉由心率變異度分析與中醫體質調查，評估針刺注意力不全過動兒的自律神經活性平衡變化。方法：三十二名兒童參與本研究，比較參與者前後測的心率變異度、注意力不全過動指標變化，進一步依體質分組分析參與兒童的心率變異度。結果：注意力不全過動兒的體質陽盛者居多（61.11%），並且與自律神經活性平衡（LF / HF）有相關。依體質陽盛組（Ya/T＞0.53）及非體質陽盛組（Ya/T＜0.53）比較，後測中自律神經活性平衡（LF/HF）及交感神經活性定量指標（nLF）有顯著性差異。結論：中醫針灸治療可以成為過動症兒童症狀改善的輔助療法選項，進而減少過動兒家庭負擔，增進生活品質。

Objective: To evaluate attention deficit and hyperactivity disorder (ADHD) children with acupuncture by heart rate variability (HRV) analysis and inquiry assessment of Chinese Medicine constitution for harmonizing effect on the heart rhythm. Methods: Thirty two ADHD children were included in this study; we compared the participants before and after acupuncture therapy on HRV and score of ADHD index. Furthermore, we compared heart rate variability in children according to group of Chinese Medicine constitution. Results: In this study, yang pattern group, most participants (61.11%), was related with LF/HF ratio. Compared yang group (Ya/T＞0.53) and non-yang group (Ya/T＜0.53), we founded the significantly differences of LF/HF ratio and LF power in normalized units (nLF) in post-test. Conclusion: Acupuncture could be a therapy help to improve ADHD symptoms of children.
