Abstract: BACKGROUND:There are many potential training exercises for office workers in an attempt to prevent musculoskeletal disorders. However, to date a suitable tool to monitor the perceived exertion of those exercises does not exist. OBJECTIVE:The primary objective of this study was to examine the validity and reliability of the Borg CR-10 scale to monitor the perceived exertion of office exercise training. METHODS:The study involved 105 staff members employed in a government office with an age range from 25 to 50 years. The Borg CR-10 scale was self-administered two times, with an interval of two weeks in order to evaluate the accuracy of the original findings with a retest. Face validity and content validity were also examined. RESULTS:Reliability was found to be high for the Borg CR-10 scale (0.898). Additionally a high correlation between the Borg CR-10 scale and Visual Analog Scale (VAS) was identified (rs = 0.754, P < 0.01). CONCLUSIONS:This study found the Borg CR-10 scale to be a reliable and valid tool for monitoring the perceived exertion of office exercise training and may potentially be useful for occupational therapists to measure physical activity intensity levels.
