Abstract
[Purpose] The inter-examiner reliability of a new hand fixation method of isometric hip extension muscle strength was verified using a hand-held dynamometer (HHD). [Subjects] The subjects were 10 healthy adult men and women. There were two examiners, one man and one woman. [Methods] A new hand fixation method was used. The elbow was fixed on the side of the treatment table with the HHD in the examiner’s hands. The method of measurement and the examiner were randomly selected from among the combinations of the two fixation methods (belt and manipulative) and the two examiners. Intraclass correlation coefficients were used to verify the intra-class and inter-class reliability. [Results] The intra-class and inter-class reliabilities of both fixation methods were “good.” [Conclusion] We consider the new hand fixation method for assessing isometric hip extension strength has high reliability.
