近红外光谱术测评拔罐治疗引起的血液动力学变化研究

Significant and sustaining elevation of blood oxygen induced by Chinese cupping therapy as assessed by near-infrared spectroscopy

目的建立一种无创、可实时监测和客观评价中医拔罐疗法治疗效果的技术。方法利用近红外光谱(NIRS)来评估13名健康志愿者在进行拔罐疗法治疗冈下肌的过程中氧合血红蛋白([HbO2])、脱氧血红蛋白([Hb])和血容量([tHb])浓度变化。结果在拔罐过程及其前后处理期间,观察到随着拔罐开始拔罐部位周围组织中的[Hb]和[tHb]均明显下降(均P<0.05),[HbO2]明显升高(P<0.05),表现出氧摄取的增加。在拔罐撤除后,上述血液动力学变化仍能持续一段时间。结论拔罐疗法在促进肌肉功能的血液动力学方面具有潜在的积极治疗效果;功能NIRS术在拔罐等物理康复治疗领域具有巨大的应用潜力。

Objective To objectively evaluate the therapeutic effect of Chinese cupping therapy.Method Near-infrared spectroscopy(NIRS)was used to evaluate the concentration change in oxygenated hemoglobin([HbO2]),deoxy-hemoglobin([Hb])and blood volume([tHb])in 13 healthy volunteers during cupping therapy for the infraspinatus muscle.Results During the cupping therapy and its pre-and post-treatment period,it was observed that[Hb]and[tHb]in the tissue surrounding the cupping site decreased significantly(both P<0.05),and[HbO2]increased significantly(P<0.05),which showed an increase in oxygen uptake.After the cupping was removed,the above hemodynamic changes could still continue for a period of time.Conclusions Cupping therapy has potential positive therapeutic effects in promoting the hemodynamics for facilitating muscular functions.Functional NIRS surgery has great application potential in the field of physical rehabilitation therapy such as cupping.
