The dynamic pulse reaction, a vascular autonomic signal, requires more research. This study demonstrates its measurement using a modified smartphone during laser ear acupuncture, providing quantitative data for better understanding.

Area of Science:

  • Physiology
  • Acupuncture Research
  • Autonomic Nervous System

Background:

  • The dynamic pulse reaction (Nogier reflex), also known as the vascular autonomic signal or Reflex-Auriculo-Cardiac (RAC), is not widely accepted or understood in current medical practice.
  • There is a need for both qualitative and quantitative research to provide scientific evidence for this phenomenon.

Purpose of the Study:

  • To demonstrate the feasibility of recording dynamic pulse reactions using a modified smartphone.
  • To present quantitative data from laser acupuncture experiments on ear acupuncture points.

Main Methods:

  • Utilized a modified smartphone for signal analysis.
  • Conducted experiments involving laser acupuncture stimulation at specific ear acupuncture points.
  • Recorded dynamic pulse reactions (vascular autonomic signals).

Main Results:

  • Successfully recorded 2 instances of dynamic pulse reactions.
  • Provided quantitative data derived from smartphone-based analysis during experimental conditions.
  • Demonstrated the potential of technology in measuring physiological responses.

Conclusions:

  • The study showcases a novel method for measuring the dynamic pulse reaction using accessible technology.
  • The presented recordings offer preliminary quantitative evidence supporting the existence and measurability of the vascular autonomic signal.
  • Further research is warranted to validate these findings and integrate the dynamic pulse reaction into clinical practice.
