Abstract
[Purpose] We decided to verify the reliability within the examiner and examiner of isometric knee extension muscle force measurement value using a digital hanging scale. [Subjects and Methods] There were 20 healthy adult males and females (10 males and 10 females) within the examiner, 10 healthy adult males and females (5 males and 5 females), which are separate from the examiner's reliability, Respectively. [Results] Both reliability within the examiner and reliability between examiners were good results. [Conclusion] There is a possibility that the digital hanging scale can be used as a device capable of quantitatively measuring the isometric knee extension muscle force.
