Abstract

CAMPOS JARA, Christian Alex et al. Validity and Reliability of the Haefni Health System 1.0 device in the measurement of the isokinetic velocity range. CPD [online]. 2014, vol.14, n.2, pp.91-98. ISSN 1989-5879.

When rating any assessment protocol one of the key issues is to determine the validity and reliability of the devices used. The aim of this study was to analyze the validity and reliability of the variable velocity isokinetic range (VRI) in Haefni Health System (HHe 1.0). Two assessment protocols were design to test bot, validity and reliability. The results showed high Index of Intraclass Correlation (ICC_2,1) for measures of validity and reliability of the VRI (0,998 and 0,99, respectively). Moreover, when the reliability was assessed at each criterion velocity high values of ICC_2,1, range 0,71-0,99 and low CV and SEM, range 0,19-3,73% and range 0.001-0.004 m·s^-1, were found respectively. The results obtained confirm the validity and reliability of HHe1.0 device for measuring VRI variable.

Keywords : accuracy; validation; reliability; velocity; isokinetic device.
