[Influence of reflex zone therapy of the feet on intestinal blood flow measured by color Doppler sonography]. / Beeinflussung der Darmdurchblutung durch Fussreflexzonenmassage, gemessen mittels farbkodierter Dopplersonographie.

ABSTRACT

OBJECTIVE: An influence on organ-associated blood flow is considered as a possible mechanism of action of reflex zone massage of the feet (FRZM) therapy. In the present study we investigated whether changes in intestinal blood flow can be achieved by FRZM. MATERIAL AND METHODS: 32 healthy adults (19 women and 13 men) were randomly assigned to the treatment or the placebo group. Subjects of the treatment group received foot massage on the zones assigned to the intestines and those of the placebo group received massage on zones unrelated to the intestines. Before, during and after FRZM, the blood flow velocity, the peak systolic and the end diastolic velocities in the superior mesenteric artery as well as the resistive index as a parameter of vascular resistance were calculated. RESULTS: During FRZM, in the subjects of the treatment group there was a significant reduction in the resistive index (p = 0.021), suggesting an increase in the blood flow in the superior mesenteric artery and the subordinate vascular system. In contrast, there were no significant changes in the resistive index in the subjects of the placebo group. CONCLUSION: The reduction in the resistive index observed in the treatment group supports the assumption that FRZM improves blood flow in the organs considered to be associated with the specific foot zones, at least during the therapy process.
