About this study

Constitution differentiation is important for the prescription of Chinese medicines. In previous studies, researchers usually used constitutional questionnaires to determine constitutions.However, the importance of tongue diagnosis and pulse diagnosis remained unclear. The specific aim of this study is to evaluation indices of tongue diagnosis, auscultative diagnosis, and pulse diagnosis in the determination of constitutions. Meeting of specialists will determine the characteristics for each constitution first. This study plans to recruit 200 volunteers and determine their constitutions by constitutional questionnaires. Tongue manifestations and pulse pressure waveforms will be taken at the same time by standardized instruments. Relations between the indices and each constitution will be determined by multiple linear regression and logistic regression analysis. Then the percentage of importance of a specific index in a specific constitutional type could be determine.

Treatment and study plan

Pulse, tongue image, and voice sound

Diagnostic Test

They are four diagnosis methods of TCM

Primary outcomes

  1. Tongue image

    Time frame: The photograph will be taken only at the first day the subject has been recruited

    A photograph of tongue will be taken and the RGB color values of the tongue will be analyzed using Photoshop software

Secondary outcomes

  1. Acoustic sound

    Time frame: The voice waves will be taken only once at the first day the subject has been recruited

    Voice wave analysis of an one-second /a/ sound (in only one time point)

  2. Pulse image

    Time frame: The pulse waveforms will be recorded at the first day the subject has been recruited

    Time-domained pulse waveform of the radial artery will be recorded for about 1 minute
