Abstract

Objectives

To interpret the meanings of Ryodoraku data and to use it as diagnosis tool, study on relationship between Ryodoraku and autonomic nervous reaction (ANR) has to be preceded prior to disease studies. This study aims to observe the change of Ryodoraku characteristics with ANR caused by treadmill exercise via a feasibility study.

Methods

The electric current at 24 Ryodoraku points(H1~H6 at left/right wrists and F1~F6 at left/right feet) and vital signs were measured at rest, immediately after the treadmill exercise test, and at later recovery times(10min, 20min, 30min, 60min, 120min after the exercise test). The calculated Ryodoraku scores (RSs) were analyzed using repeated ANOVA test.

Results

The RSs in the wrist Ryodoraku points were significantly increased immediately after the exercise (p<.05) and at 10min recovery time (p<.01), and no significant differences were found during the rest of the experimental sets. To the contrary, the RSs in the feet Ryodoraku points showed less difference throughout all the measurement time.

Conclusions

The Ryodoraku characteristics change more sensitively in the wrists than in the feet in accordance with the previously reported sweat gland responses of the treadmill exercise. This is the first feasibility study to observe the change of Ryodoraku characteristics caused by treadmill exercise, and it shows the Ryodoraku characteristics are in accordance with known ANS responses.
