Portable Nadi Pareeksha Device: Integrating Traditional Ayurvedic Diagnosis with Modern Sensor Technology

Abstract

Introduction:

Nadi Pareeksha (pulse diagnosis) is a traditional Ayurvedic diagnostic technique used to assess physical, mental, and spiritual imbalances. While highly subjective and dependent on the practitioner’s skill, recent advancements in biomedical engineering have led to the development of a Portable Nadi Pareeksha Device to make pulse diagnosis more accessible and accurate.

Methods:

The device integrates non-invasive pressure and vibration sensors to detect pulse signals from three specific points on the wrist (representing Vata, Pitta, and Kapha doshas). These signals are processed through a signal processing unit, and an algorithm maps the pulse characteristics to doshic imbalances. The device is designed to be handheld and portable, making it suitable for both urban and rural healthcare settings. Preliminary clinical validation was conducted using a cohort of volunteers, comparing device-generated results with traditional manual pulse assessments.

Results:

Early tests demonstrated that the portable device can capture pulse waveforms and provide a real-time assessment of dosha imbalances, offering a faster and more consistent alternative to traditional methods. The device also proved to be reliable and easy to use, even in remote locations.

Discussion:

The portable Nadi Pareeksha device presents a promising tool for modernizing Ayurvedic diagnostics. It allows for faster, more accessible, and reproducible results, potentially improving healthcare delivery, especially in underserved areas. Further validation and large-scale studies are required to refine the device’s accuracy and application in clinical settings.
