Arterial pulse-based diagnostics is an age-old diagnostic technique used worldwide. One of the most effective non-invasive diagnostic methods for assessing the condition of the distal radial artery (DRA) profile is ultrasound Doppler examination in B-mode. The purpose of this study was to measure the DRA’s pulse wave velocity (PWV) and resistive index (RI) in various pulse patterns. Methods: A total of 36 healthy volunteers between the ages of 18 and 35 years participated in this pilot study. To begin the examination, the hand was semiflexed for the palpatory approach by an ayurvedic doctor who performed the palpatory test and had extensive training in naadi pariksha. Dosha expressions were recorded at the index, middle, and ring fingers. In the second test: the ultrasonography (USG)-B mode study of the same patients was done within 10 minutes of the palpatory test on the distal radial arterial pulse, by a radiologist who was blinded to the results of the palpatory naadi examination. RI, PWV, radial artery diameter, and intima media thickness were the measures of the DRA pulse gathered with USG of DRA. One-way ANOVA was used to statistically analyze the relationship between naadi type and USG parameters at the P < 0.05 (5%) level of significance. Results: Compared to pittaja naadi (0.802 ± 0.10), kaphaja naadi (0.640 ± 0.17), and sama naadi (0.6938 ± 0.28), vataja naadi’s resistance index (0.5019 ± 0.20) was noticeably lower. In comparison to pittaja naadi (0.882 ± 0.70 mm/sec), kaphaja naadi (0.651 ± 0.45 mm/sec), and sama naadi (0.51 ± 0.24 mm/sec), vataja naadi’s PWV(pulse wave velocity) was low 0.474 ± 0.3 mm/sec. Conclusion: Distinct naadi patterns are linked to variations in blood flow properties. Hence, the technological framework of the ultrasonic Doppler method for RI and PWV made this examination more objective for the researchers and students.
