Immediate effect of bowl sound therapy and mind sound resonace technique on state anxiety and psychomotor performance in healthy volunteers: a self controlled comparative study

Abstract

Objectives: To compare the immediate effect of Bowl sound therapy (BST) with Mind Sound Resonance Technique (MSRT) on state anxiety (SA) and psychomotor performance (PMP) in 30 right handed (19-males &13-females) healthy volunteers with age range 21-34 years (26.96±3.54 years). Methodology: A self-controlled comparative study design was followed. State anxiety and psychomotor performance were assessed using STAI-XI and DLST respectively, before and immediately after each intervention on three consecutive days. Participants practiced BOWL SOUND, MSRT and SR (as a self-control intervention) at the same time for three consecutive days respectively. The sequence of intervention was assigned randomly to the participants. Intervention was given in a quiet dark room, after lunch. Subjects received a training of BOWL SOUND, MSRT and SR for immediate before the data and after data was taken. A trained yoga instructor administered the technique of BOWL SOUND, MSRT to all the subjects. Data was found normally distributed by Kolmogorov-Smirnov test. The changes in the STAI and DLST scores were analysed using paired and independent samples t test and different between test. Results: Within group comparison showed that during BOWL SOUND there was significant improvement in total, net score and reduction wrong score in but there was no significant reduction in anxiety. DLST score (STAI; p=0.81; DLST; p = 0.001**) and MSRT, (STAI p=0.59; DLST p=0.001) During SR, there was no significant change within the group for both STAI (p = 0.094) and DLST scores (p = 0.431). Between groups comparison revealed that STAI scores reduced significantly during MSRT as compared to BOWL SOUND (p=0.467). But there was no significant difference between the groups for DLST scores (p = 0.128). Between groups comparison revealed that STAI scores reduced significantly during MSRT as compared to SR (p=0.066). But there was no significant difference between the groups for DLST scores (p = 0.007**). Conclusion: BOWL SOUND THERAPY and MSRT are effective interventions in improving the psychomotor performance, in which MSRT is more effective than bowl sound therapy.
