Increase in tissue blood flow is one of the most acknowledged potential effects of massage; however, actual research studies examining this phenomenon are inconsistent and inconclusive. One possible reason for continued uncertainty regarding this topic is methodology, specifically how tissue blood flow is measured because limitations exist in previously utilized technologies. Near-infrared spectroscopy (NIRS) affords massage researchers a versatile and non-invasive measurement option by providing dynamic information on oxy- and deoxy-hemoglobin concentrations, total hemoglobin concentration, and blood oxygen saturation in deep tissue. Near-infrared diffuse correlation spectroscopy (DCS) is an innovative technique for continuous non-invasive measurement of blood flow in deep tissue. The combination of these two technologies has resulted in a novel hybrid diffuse optical instrument for simultaneous measurement of limb muscle blood flow and oxygenation. The purposes of this short report are to review previous blood flow measurement techniques and limitations in massage therapy research, introduce a novel hybrid near-infrared diffuse optical instrument that addresses previous limitations in the assessment of hemodynamic properties, outline a proposed massage therapy pilot study utilizing the novel measurement technology, and present sample data from a pilot participant using the introduced novel technology.
组织血流量增加是按摩最广为人知的潜在效果之一；然而，针对这一现象的实际研究结果并不一致且尚无定论。关于该主题持续存在不确定性的一个可能原因是方法学问题，特别是组织血流量的测量方式，因为先前使用的技术存在局限性。近红外光谱技术（NIRS）通过提供深部组织中氧合血红蛋白和脱氧血红蛋白浓度、总血红蛋白浓度以及血氧饱和度的动态信息，为按摩研究人员提供了一种通用且非侵入性的测量选择。近红外扩散相关光谱技术（DCS）是一种用于连续非侵入性测量深部组织血流的创新技术。这两种技术的结合产生了一种新型的混合漫射光学仪器，可同时测量肢体肌肉血流和氧合情况。本简短报告的目的是回顾按摩疗法研究中先前的血流测量技术及局限性，介绍一种解决先前血流动力学特性评估局限性的新型混合近红外漫射光学仪器，概述一项使用该新型测量技术的按摩疗法试点研究计划，并展示一名试点参与者使用所介绍的新技术的样本数据。
