The purpose of this study was to compare the reliability of both a calliper device and digital photographic method in determining the arch height index AHI . Methods Twenty subjects underwent measurements of AHI on two separate days. On each day AHI measurements during both sitting and standing were taken using the AHIMS and digital photographic methods by the same single tester. The intra-tester reliability of each measurement technique was assessed using intraclass correlation coefficients ICC and standard error of measurement SEM . Additionally the relationship between AHI measurements derived from the two different methods was assessed using a correlation analysis. Results The reliability for both the AHIMS and digital photographic methods was excellent with ICC values exceeding and SEM values of less than for the AHI. Moreover the reliability of both measurement techniques was equivalent. There was a strong positive correlation between the AHI values collected using both methods. AHI values calculated using the digital photographic method tended to be greater than those derived using the AHIMS. Conclusion Digital photographic methods offer equivalent intra-tester reliability to previously established calliper methods when assessing AHI. While AHI measurements calculated using both methods were highly related the greater AHI values in the photographic method implied caution should be exercised when comparing absolute values between the two methods. Future studies are required to determine whether digital photographic methods can be
