The purpose of this study was to use laser Doppler flowmetry (LDF) with wavelet analysis to investigate skin blood flow control mechanisms in response to various intensities of cupping therapy. To the best of our knowledge, this is the first study to assess skin blood flow control mechanism in response to cupping therapy using wavelet analysis of laser Doppler blood flow oscillations.
Twelve healthy participants were recruited for this repeated-measures study. Three different intensities of cupping therapy were applied using 3 cup sizes at 35, 40, and 45 mm (in diameter) with 300 mm Hg negative pressure for 5 minutes. LDF was used to measure skin blood flow (SBF) on the triceps before and after cupping therapy. Wavelet analysis was used to analyze the blood flow oscillations (BFO) to assess blood flow control mechanisms.
The wavelet amplitudes of metabolic and cardiac controls after cupping therapy were higher than those before cupping therapy. For the metabolic control, the 45-mm cupping protocol (1.65 ± 0.09) was significantly higher than the 40-mm cupping protocol (1.40 ± 0.10, P < .05) and the 35-mm cupping protocol (1.35 ± 0.12, P < .05). No differences were showed in the cardiac control among the 35-mm (1.61 ± 0.20), 40-mm (1.64 ± 0.24), and 45-mm (1.27 ± 0.25) cupping protocols.
The metabolic and cardiac controls significantly contributed to the increase in SBF after cupping therapy. Different intensities of cupping therapy caused different responses within the metabolic control and not the cardiac control.
本研究旨在使用激光多普勒血流仪（LDF）和小波分析来研究皮肤血流控制机制对不同强度拔罐疗法的反应。据我们所知，这是第一项使用激光多普勒血流振荡的小波分析评估拔罐疗法对皮肤血流控制机制的研究。
本研究采用重复测量设计，共招募了 12 名健康志愿者。使用 3 种不同直径（35、40 和 45 毫米）的杯子，在 300 毫米汞柱负压下以 5 分钟的时间施加 3 种不同强度的拔罐疗法。在拔罐治疗前后，使用 LDF 测量肱三头肌的皮肤血流（SBF）。采用小波分析分析血流振荡（BFO），以评估血流控制机制。
拔罐治疗后代谢和心脏控制的小波振幅均高于治疗前。对于代谢控制，45 毫米拔罐方案（1.65±0.09）明显高于 40 毫米拔罐方案（1.40±0.10，P<.05）和 35 毫米拔罐方案（1.35±0.12，P<.05）。35 毫米（1.61±0.20）、40 毫米（1.64±0.24）和 45 毫米（1.27±0.25）拔罐方案的心脏控制之间无差异。
代谢和心脏控制显著促进了拔罐治疗后 SBF 的增加。不同强度的拔罐疗法在代谢控制中引起了不同的反应，而不是心脏控制。
