“…The reproducibility, accuracy and precision of the instrument has been studied and the results were found to be consistent across multiple recordings at different times [18] . The studies on pulse rate variability [19] , beat-to-beat alterations [20] , and spectral analysis [21] using Nadi Tarangini have shown significant results.…”

Background/Aims:The studies on the effect of integrated yoga therapy have shown significant results in improving the overall health. However, the effect of integrated yoga therapy on arterial stiffness is not yet established. The aim of the study was to investigate the effect of integrated yoga therapy on arterial stiffness measured at the radial artery. Methods: A total of 18 participants were included in the study. The participants were divided into three groups based on their age and body mass index. There were 5 participants in group 1 who were considered as nonobese, 7 younger adults with obesity were included in group 2, and 6 older adults with obesity were included in group 3. A 1-week integrated approach of yoga therapy (IAYT) was given as an intervention to the participants. The pulse data was acquired from participants using Nadi Tarangini at the beginning and end of the yoga program. The stiffness index (SI) and reflection index (RI) were computed from the pulse data. The data were analyzed using the paired-samples t test. Results: There was a significant reduction in SI ( p < 0.05) after IAYT in young participants with obesity. There was a significant reduction in BMI after IAYT in older adults, but the SI was only significantly low in young adults. There were no significant changes in RI after IAYT. Conclusion: The pilot study has shown that arterial stiffness measured at the radial artery using Nadi Tarangini has decreased significantly after 1 week of IAYT in young adults with obesity compared to older adults.

“…It is observed that, pulse duration increases and pulse rate decrease with the age [13]. Multifractality analysis explored self-similarity in arterial pulse and is used for diagnosis of skin disorder, aging and diabetes [14]. Kalange et al proposed a system in which a transducer based on piezoelectric properties was used for detecting the human pulse.…”

In present scenario, the human health condition is being diagnosed by various advanced sophisticated equipments. Moreover, the process of diagnosis is becoming expensive and painful. In ancient Indian Ayurveda and Traditional Chinese Medicine (TCM), wrist pulse was used to diagnose the health status of the subject and to envision the root cause of a disease. According to Ayurveda, a person's health status depends on three essential components and the imbalance of a component is the symptom of a disease. Practitioner determines the unhealthiness of a subject, based on the wrist pulse parameters such as pulse strength, amplitude shape, vega, rhythm, pulse width and transition period. Evaluation of the vital information of the components depends exclusively upon the perception of the practitioner and varies from practitioner to practitioner based on his/her expertise or experience. No modern technique can determine the pathological condition of a subject. The paper presents a review of wrist pulse parameters for diseases like diabetics, hypertension, gastritis, etc.

“…Recently the arterial pulse signals have had a minor renaissance and quantified; results on the shape of the arterial pulse signals show variations with age in [8] (through the shift of multifractal spectrum), with gender in [2] (through variations in augmentation index), and variability analysis in [7] (through various time domain, frequency domain and nonlinear Poincaré-based parameters).…”

Pseudo-periodic signals are rampant in biomedical applications but are difficult to analyze. One approach is to compute time domain parameters of each individual cycle in the pseudo-periodic signal. The classic approach requires repeated computation in each cycle, which tends to be either error prone, computationally burdensome, or requires manual effort.We provide a novel combination of the pitch synchronous wavelet transform which when combined with dynamic time warping results in effective quantification of cycles in the pseudo-periodic signal. We demonstrate our application of this method in studying the arterial pulse. The results show that our approach is feasible and effective, and confirms further scope in other applications.
