Design outcomes

Primary

MeasureTime frame
1. Middle latency auditory evoked response (MLR), 2. Heart rate variability (HRV) and 3. Respiration rate (RR). Timepoint: In each session there will be (i) Baseline (5 minutes), (ii) During (18 minutes with three epochs of 5 minutes with one minute rest between two consecutive epochs) and (iii) Post (5 minutes).

Secondary

MeasureTime frame
1. Mood using Brief mood introspection scale (BMIS), 2. Symptoms of hyperventilation syndrome using Nijmegen questionnaire (NQ) and 3. Quality of intervention using Visual analogue scale (VAS).Timepoint: 1. For BMIS, in each session there will be:(i) Baseline and (ii) Post assessment (after 18 minutes of intervention). 2. For NQ and VAS, in each session there will be: (i) Only post assessment (after 18 minutes of intervention).
