Abstract:
Objective To evaluate the intra-and inter-rater reliability of MyotonPRO for Achilles tendon properties measured. Methods Twenty healthy subjects were recruited to measure Achilles tendon properties using a novel hand-held Myoton-PRO device by two testers, one of the testers re-tested five days later. The reliability was assessed using in-tra-class correlation coefficient (ICC) and Bland-Altman analysis, and minimum detectable changes (MDC) was calculated. The Achilles tendon properties of the dominant or non-dominant leg was compared. The correlation between body mass and Achilles tendon properties was examined. Results The intra-rater reliabilities of Achilles tendon properties were ICCleft=0.884 and ICCright=0.904; the inter-rater reli-abilities were ICCleft=0.883 and ICCright=0.945. The MDC was 36.64 N/m. Bland-Altman plots showed good agreement. There was no significant difference in Achilles tendon properties between dominant and non-domi-nant legs (t<1.236, P>0.05). The body mass positively correlated with Achilles tendon properties (r>0.477, P<0.05). Conclusion The intra-and inter-rater reliabilities of MyotonPRO were good in measuring Achilles tendon properties in healthy subjects. No significant difference was found between dominant and non-dominant legs. The body mass positively correlated with Achilles tendon properties in healthy subjects.
