RESUMO
BACKGROUND: Meditation has shown positive results in improving the psychological disorders such as anxiety. There is a need to study the therapeutic benefits of Anapanasati meditation, a mindfulness meditation technique. PURPOSE: The study aims at investigating the effect of Anapanasati meditation on individuals with moderate anxiety. METHODS: A total of 112 participants who were willing to participate in the study were recruited for the study. Anapanasati meditation was used as an intervention. The participants were divided into two groups experiment and control groups. Experiment group had 56 persons performing Anapanasati meditation and Control group had 56 persons not performing any type of meditation. The experiment group practiced one hour of Anapanasati meditation daily under the supervision of experts for six months and continued their daily routine and control group was not given any intervention, but they continued their daily routine. State Trait Anxiety Inventory (STAI) is used to assess the anxiety level. RESULTS: The STAI score before and after Anapanasati meditation was analysed for both experiment and control groups using Paired Samples T test. The experiment group has shown significant reduction in the STAI (P < 0.05) score after the intervention whereas in the control group the reduction in STAI score was not significant. CONCLUSION: This study has shown that after six months of intervention, the subjects with moderate anxiety who practiced Anapanasati meditation had a significant decrease in their STAI score and the control group has not shown significant change in the STAI score.
RESUMO
The significance of Nadi Pariksha is well understood and effectively used by Ayurveda practioners for assessing Tridoshas and various physiological and psychological states of the patient. The traditional texts Sarangadhara Samhita, YogaRatnakara, Basavarajeeyam and Bhavaprakasha have discussed the details of Nadi Pariksha in succinct set of slokas. Ayurveda has thousands of years of rich experience in Nadi Pariksha with strong literature support but is subjective in nature and the need for studying nadi with a scientific approach is well understood. Recently, pulse wave velocity has gained significant research interest as it is considered to be a strong indicator of cardiovascular disease; however, the relevance of pulse wave analysis to Nadi Pariksha has not been studied. In this review, traditional methods of Nadi Pariksha as defined in Ayurveda classics and the recent advances in pulse wave analysis are discussed. As per classical texts, qualities or properties of pulse such as pulse movement (gati), speed of the pulse (vega), stability of the pulse (sthiratva) and hardness of the artery (kathinya) play major role in Nadi Pariksha and in the current review these properties were analyzed and compared with the modern pulse parameters namely pulse wave velocity, pulse rate variability and arterial stiffness. The significance of pulse wave velocity in cardiovascular studies is discussed and the need for extending these studies to Ayurveda is highlighted.
