Researchers in Austria studied the effects of reflexology upon renal blood flow. 32 healthy young adults (17 women, 15 men) participated in a placebo-controlled, double blind trial. The treatment group received reflexology at zones corresponding to the right kidney. The placebo group received treatment on other foot zones. The blood flow of 3 vessels of the right kidney was measured then monitored prior to, during and following reflexology. Systolic peak velocity and end diastolic peak velocity were measured and resistive index calculated.
The two groups showed significant differences; a highly significant decrease showed during and following reflexology. There were no differences between men and women nor smokers and non-smokers. These results are consistent with the hypothesis that reflexology is effective in influencing renal blood flow and confirms the results of independent research that reflexology can significantly help kidney function.
