Key result
Time and frequency domain analysis of wrist pulse signals identified parameters that correlate with ancient Ayurvedic characteristics and vary significantly between healthy and unhealthy subjects.
Why the study?
Can time and frequency domain analysis of wrist pulse signals differentiate between healthy and unhealthy subjects according to ancient Indian medicine principles?
Observational
Can time and frequency domain analysis of wrist pulse signals differentiate between healthy and unhealthy subjects according to ancient Indian medicine principles?
Time and frequency domain analysis of wrist pulse signals may provide a quantitative basis for traditional Ayurvedic pulse diagnosis.
May quantify Ayurvedic pulse features; hypothesis-generating and requires prospective validation before any clinical use.
Wrist pulse analysis is an approach of health diagnosis described in ancient Indian medicine. This approach is based on the analysis of three fingertip palpations observed over radial artery of both the hands. These three palpations identified as Vata, Pitta and Kapha in this approach are described by their unique characteristics. The characteristics of Vata and Pitta signals are explained by an irregularity present in the signal and the jumping or throbbing nature associated with the signal, respectively. In this paper, these wrist pulse signals are analysed in healthy and unhealthy subjects with the help of time and frequency domain signal processing techniques. Several pulse parameters are computed and their correlation is established with the corresponding pulse characteristics defined in ancient literature. These pulse parameters are also verified for their significant variations in healthy and unhealthy states of the subjects.

Thakker et al. (2014) conducted an observational in Healthy and unhealthy states. Wrist pulse analysis (time and frequency domain signal processing) vs. Healthy vs unhealthy subjects was evaluated on Correlation of computed pulse parameters with ancient literature characteristics and variations between healthy and unhealthy states. Time and frequency domain analysis of wrist pulse signals identified parameters that correlate with ancient Ayurvedic characteristics and vary significantly between healthy and unhealthy subjects.
