Effect of verbal encouragement and visual biofeedback on peak expiratory flow rate in healthy young subjects
Journal Title: International Journal of Allied Medical Sciences and Clinical Research - Year 2016, Vol 4, Issue 3
Abstract
Background & Aim of study Peak expiratory flow rate is simple and common method of measuring airway obstruction. The aim of this study is to find out the effects of verbal encouragement and visual biofeedback during the performance of peak expiratory flow. Methodology 60 Healthy young subjects, first and second year bachelor of physiotherapy (B.P.T.) students of Charotar institute of physiotherapy, Changa, Gujarat were selected. Students were briefly stated about the nature and intervention of the study and informed consent were taken. The method of peak expiratory flow was demonstrated to all subjects. After checking for inclusion and exclusion criteria, participants were randomly selected and assigned to two different orders of peak expiratory flow rate (PEFR) assessments. Each subject went through peak expiratory flow rate assessments including with an intervention (verbal encouragement and visual biofeedback) and without the intervention (without verbal encouragement and visual biofeedback).Outcome measure: Peak expiratory flow rate by peak flow meter. Result Results shows a significant difference in PEFR with p value < 0.0001.Without intervention PEFR - Mean ± SD =290.50 ± 91.270.With intervention PEFR - Mean ± SD =341.67 ± 85.552. Conclusion The efficiency and reproducibility of peak expiratory flow can be affected by verbal encouragement and visual biofeedback during PEFR measurements.
