Various cupping sizes of cupping therapy have been used in managing musculoskeletal conditions; however, the effect of cupping sizes on skin blood flow (SBF) responses is largely unknown.
The objective of this study was to compare the effect of three cupping sizes of cupping therapy on SBF responses.
Laser Doppler flowmetry (LDF) was used to measure SBF on the triceps in 12 healthy participants in this repeated measures study. Three cup sizes (35, 40 and 45 mm in diameter) were blinded to the participants and were tested at -300 mmHg for 5 minutes. Reactive hyperemic response to cupping therapy was expressed as a ratio of baseline SBF.
All three sizes of cupping cups resulted in a significant increase in peak SBF (p< 0.001). Peak SBF of the 45 mm cup (9.41 ± 1.32 times) was significantly higher than the 35 mm cup (5.62 ± 1.42 times, p< 0.05). Total SBF of the 45 mm cup ((24.33 ± 8.72) × 103 times) was significantly higher than the 35 mm cup ((8.05 ± 1.63) × 103 times, p< 0.05). Recovery time of the 45 mm cup (287.46 ± 39.54 seconds) was significantly longer than the 35 mm cup (180.12 ± 1.42 seconds, p< 0.05).
Our results show that all three cup sizes can significantly increase SBF. The 45 mm cup is more effective in increasing SBF compared to the 35 mm cup.
在治疗肌肉骨骼疾病时，各种大小的拔罐疗法都有被使用；然而，拔罐大小对皮肤血流（SBF）反应的影响在很大程度上尚不清楚。
本研究的目的是比较三种大小的拔罐疗法对 SBF 反应的影响。
在这项重复测量研究中，使用激光多普勒血流仪（LDF）测量了 12 名健康参与者肱三头肌的 SBF。三种杯具大小（直径 35、40 和 45 毫米）对参与者是盲测的，在-300mmHg 下测试 5 分钟。拔罐疗法的反应性充血反应表示为 SBF 基线的比值。
所有三种大小的拔罐杯都导致 SBF 峰值显著增加（p<0.001）。45 毫米杯的 SBF 峰值（9.41 ± 1.32 倍）明显高于 35 毫米杯（5.62 ± 1.42 倍，p<0.05）。45 毫米杯的总 SBF（（24.33 ± 8.72）×103 倍）明显高于 35 毫米杯（（8.05 ± 1.63）×103 倍，p<0.05）。45 毫米杯的恢复时间（287.46 ± 39.54 秒）明显长于 35 毫米杯（180.12 ± 1.42 秒，p<0.05）。
我们的结果表明，所有三种杯具大小都能显著增加 SBF。与 35 毫米杯相比，45 毫米杯更能有效地增加 SBF。
