Analysis of Effects of Aroma Foot Care Using Functional Near-infrared Spectroscopy

AbstractFoot care is attracting attention as a medically effective treatment of the foot lesions caused by diabetes or aging. In this study, we experimentally examined how aromatherapy affects the functions of the human brain during foot care by using functional near-infrared spectroscopy (fNIRS). Four female subjects received foot care massages and aroma oil massages. We analyzed the changes in their oxygenated hemoglobin (oxy-Hb) concentrations based on their brain activity by t-tests, and the t-test results showed significant differences between the foot and aroma oil massages. Our questionnaire results obtained from our subjects showed that they felt more comfortable and relaxed while receiving foot care with aroma oils. These results suggest that aroma oil massages are an effective foot care tool
