[Purpose] The purpose of this study was to examine the intra-and inter-rater reliabilities of lower extremity muscle strength assessment of healthy adults using hand held dynamometer. [Subjects and Methods] A total of 55 students (19 males and 36 females) in Y University in Gyeongsangnam-do, South Korea participated in this study. Lower extremity muscle strength was measured using a hand-held dynamometer (Commander Muscle Tester, JTech, USA). Flexion and extension strengths of the hip joint, the knee joint, and the ankle joint were measured. [Results] The intra-rater reliabilities were excellent (above 0.9) for the flexion and extension strengths of the ankle, knee, and hip joints. The inter-rater reliabilities were also excellent (above 0.8) for the flexion and extension strengths of the ankle, knee, and hip joint. [Conclusion] Lower extremity muscle strength assessment using a hand-held dynamometer provided consistent results when conducted by different examiners and when measured several times. Therefore, this method is a useful way of deriving objective and quantitative measurement values.
