Thirty five patients, most of them athletes, with chronic Achilles tendinopathy were enrolled in a study of tendon blood flow using laser Doppler flowmetry at rest and during physical provocation by passive stretch and contraction of the triceps. The patients were compared with a group of 40 healthy volunteers assessed according to a similar protocol in a previous study. In both groups values were significantly lower at the distal insertion, but otherwise the values were evenly distributed throughout the tendon. Blood flow in the symptomatic tendons was significantly elevated as compared with the controls. Both groups demonstrated a similar vascular response to physical loading, a progressive decline in blood flow as tension increased. Contrary to popular belief chronic Achilles tendinopathy is associated with an increased blood flow of uncertain origin. A local deficiency in tendon blood supply does not initiate the lesion nor does it explain why the condition persists.
35名患者（其中大多数为运动员）患有慢性跟腱病，他们参与了一项关于跟腱血流的研究，该研究使用激光多普勒血流仪在静息状态下以及通过被动伸展和三头肌收缩进行物理刺激时测量血流。将这些患者与在先前一项研究中按照类似方案评估的40名健康志愿者组成的对照组进行比较。在两组中，远端附着点处的血流值均显著较低，但除此之外，血流值在整个肌腱中分布均匀。与对照组相比，有症状肌腱的血流显著升高。两组对物理负荷均表现出相似的血管反应，即随着张力增加血流逐渐下降。与普遍看法相反，慢性跟腱病与来源不明的血流增加有关。肌腱局部血液供应不足既不会引发病变，也无法解释病情为何持续存在。
