摘要
重要性:了解穴位微环境对优化疗效至关重要。评估这些穴位的含水量变化可进一步了解针灸对组织的影响:本研究旨在测量组织介电常数(TDC)并评估含水量的变化,特别是胃 36(ST36,足三里)和脾 6(SP6,三阴交)穴位的含水量变化:在一项对照、盲法、随机试验中,根据 TDC 传感器直径(XS、M 和 L)将 113 名健康志愿者分为六组:三组对照组和三组针灸组。他们在三个时间点接受评估:T1,基线;T2,拔针后 20 分钟;T3,拔针后 40 分钟。此外,还对电阻抗(EI)进行了分析。显著性水平设定为 p < 0.001:在 T2 和 T3 使用 XS 探头时,ST36 和 SP6 的 TDC 与 T1 时相比明显下降(F8,452:54.61)。使用 M 和 L 探头时,TDC 在 T2 和 T3 之间没有明显变化。EI 数据显示,在 T2 和 T3 期间,SP 组(F2,226:39.32)和 ST 组(F2,226:37.32)的电流通过量比各自组别和对照组在 T1 期间的电流通过量有所增加:本研究证明了 TDC 测量在检测穴位含水量波动及其对针刺的反应方面的有效性。经 EI 验证的 TDC 测量可为了解穴位微环境提供有价值的信息,从而有助于优化治疗。
Evaluating Dielectric Properties for Assessing Water Content at Acupuncture Points: New Methodology.
Importance: Understanding acupuncture point microenvironments is vital for optimizing treatment efficacy. Evaluating changes in water content at these points can provide further insights into the effects of acupuncture on tissues.
Objective: This study aimed to measure tissue dielectric constant (TDC) and assess changes in water content, specifically at stomach 36 (ST36, Zusanli) and spleen 6 (SP6, Sanyinjiao) acupuncture points.
Methods: In a controlled, blinded, randomized trial, 113 healthy volunteers were divided into six groups based on TDC sensor diameters (XS, M, and L): three control groups and three acupuncture groups. They were assessed at three time points: T1, baseline; T2, 20 min post-needle withdrawal; and T3, 40 min post-needle withdrawal. Electrical impedance (EI) was also analyzed. Significance level was set at p < 0.001.
Results: TDC at ST36 and SP6 significantly decreased with the XS probe at T2 and T3 compared with that at T1 (F8, 452: 54.61). TDC did not significantly vary between T2 and T3 with M and L probes. EI data indicated that the current passage increased in the SP (F2, 226: 39.32) and ST (F2, 226: 37.32) groups during T2 and T3 compared with that during T1 within their respective groups and controls.
Conclusions: and Relevance: This study demonstrated the efficacy of TDC measurements in detecting water content fluctuations at acupuncture points and their responses to needles. TDC measurements, which were validated against EI, provide valuable insights into acupuncture point microenvironments and thus help optimize treatments.
