To investigate whether the manipulation parameter of the twirling frequency in acupuncture affects the blood pressure when acupuncture is applied on the acupoints ST9 and LR3 in a human body.
A randomized, controlled trial.
A hundred and twenty patients with hypertension were randomized into four treatment groups. A twirling frequency of 120 twirls per minute or 60 twirls per minute were respectively applied on the acupoints ST9 or LR3. Each patient received five acupuncture sessions a week over a period of 12 weeks, with a follow-up period of a further12 weeks. The outcome was assessed by using an ambulatory blood pressure monitor.
A hundred and twenty twirls per minute on ST9 could overall improve the BP (24hDBP, mSBP, mDBP, dDBP, nSBP and nDBP). Sixty twirls per minute on ST9 improved the 24hDBP, dSBP, dDBP and mDBP; 120 twirls per minute on LR3 did not show any anti-hypertensive effect, while 60 twirls per minute on LR3 improved the dSBP and dDBP. The results indicated that the acupuncture effect on BP, the onset of anti-hypertensive effect, the occurrence of the effect, and the duration of the effect depended on the frequency of needle manipulation on the same acupuncture point.
As one of the important factors of the effects of acupuncture, the manipulation parameter's impact has its specificity for different acupoints. Thus, in the future, close attention needs to be paid to this clinically.

探讨针刺穴位 ST9 和 LR3 时捻转频率的操作参数是否会影响人体血压。
随机对照试验。
将 120 例高血压患者随机分为 4 个治疗组。在 ST9 或 LR3 穴位上分别施以 120 转/分钟或 60 转/分钟的捻转频率。每个患者每周接受 5 次针刺治疗，共 12 周，随后进行 12 周的随访。采用动态血压监测仪评估疗效。
ST9 每分钟 120 转可全面改善血压（24hDBP、mSBP、mDBP、dDBP、nSBP 和 nDBP）。ST9 每分钟 60 转可改善 24hDBP、dSBP、dDBP 和 mDBP；LR3 每分钟 120 转无降压作用，而 LR3 每分钟 60 转可改善 dSBP 和 dDBP。结果表明，针刺对血压的影响、降压作用的出现、作用的发生和作用的持续时间取决于同一穴位的针刺频率。
作为针刺效应的重要因素之一，操作参数的影响对不同穴位具有特异性。因此，未来需要在临床上密切关注这一点。
