Effect of Mind Sound Resonance Technique on Autonomic Variables in People with Visual Impairment-A Pilot Study

Individuals with visual impairment undergo physical, emotional, behavioural problems as reported by the previous studies. Mind Sound Resonance Technique (MSRT) is known to be effective in decreasing anxiety, stress, and psychological distress. The aim of this study is to examine the effects of MSRT on autonomic variables in people with visual impairment. Seven male and female participants with visual impairment took part in a 6-week Mind sound resonance technique intervention. Autonomic variables using HRV device was recorded before and 6 weeks after the intervention. There was a significant effect of MSRT on autonomic functions. There was a significant increase in HRV (pless than0.05) on HF power, RMSSD and SDRR. There were no significant changes in other autonomic measures such as RR, LF power, LF/HF ratio. This studyshows that six weeks of MSRT intervention improved autonomic functions significantly which suggest parasympathetic dominance over sympathetic activity.
