Translation and validation of the modified borg scale (CR-10) in Hindi language in healthy Indian adults

Abstract

Objective: The present study was conducted to translate the original English version of Modified Borg Scale (CR-10) in Hindi language and validate Hindi translated version of the scale for its use in healthy Indian adult population. Subjects and Methods: An observational analytical study was conducted on 50 healthy Indian subjects (24 males, 26 females) who were recruited from a tertiary healthcare setup. The study was conducted in two parts: 1st part included translation of English version of Modified Borg Scale (CR-10) in Hindi language by cross-cultural adaptation process. 2nd part included validation of Hindi translated version of Borg CR-10 scale by correlating subjective values of rating of perceived exertion (RPE) with the objective parameters of heart rate (HR) and maximal oxygen consumption (VO2 max) during a Bruce treadmill protocol. Results: Spearman correlation coefficient was computed between subjective and objective measures. The results of the study showed that there was a high positive correlation between RPE and HR with r = 0.822, P < 0.01 and r = 0.97, P < 0.05 by using two different methods of statistical analysis. There was a moderate correlation between RPE and VO2 max with r = 0.587, P < 0.01 by using method 1 and a high correlation with r = 0.98, P < 0.05 by using method 2. Conclusion: The Hindi version of Borg CR-10 Scale is a valid tool to measure perceived exertion during Bruce protocol on a motorized treadmill in a healthy Indian adult population.
