“…Knee isokinetic peak torque measurements at this angular velocity have been shown to have high reliability, with an intraclass correlation coefficient (ICC) of 0.91 for subjects without pain and for different age groups. 12 Isokinetic ankle dorsiflexion and plantar flexion muscle strength tests were performed with the subject in supine, the hip and knee joints extended, and the limb fixed. The ankle joint testing range was set at 5° dorsiflexion to 40° plantar flexion.…”

Abstract.[Purpose] The purpose of this research was to study the test-retest reliability of isometric knee extension muscle strength measurement using a hand-held dynamometer (HHD) with a belt, with healthy elderly people living in the community as subjects.[Subjects] The subjects were healthy elderly people living in the community, with an average age of 70.5 years, and measurements were made of the leg on the side that was used to kick a ball.[Method] The subjects sat on a mat table, and isometric knee extension muscle strength measurements using a HHD with a belt were conducted twice, at an interval of 30 seconds, with a knee flexion angle of 90 degrees. The measurement values were classified according to the gender of the subjects, and by age group 65-69 years, 70-74 years, and 75 years and above, and studied. Testretest reliability was studied using the intraclass correlation coefficient (ICC) and checks of the differentials.[Results] The ICC(1,1) between the first and second measurements ranged from 0.85 to 0.92. Apart from the group of men aged 75 years and above, the second measurement values were higher than those of the first.[Conclusion] Test-retest reliability of isometric knee extension muscle strength measurement using a HHD with a belt was high in healthy elderly persons. However, measuring only once, or measuring twice and taking the average was considered inappropriate, since there is the possibility that the values in such cases would be lower than the actual muscle strength.

“…Within-session testeretest reliabilities ranged from good to excellent (ICC ¼ 0.83e0.94) for women (n ¼ 17) 18 . When assessed twice over 1 week, ICCs ranged from 0.82 to 0.96 depending on knee angle in 18 adults with mild symptomatic OA 19 . Further, isometric strength displayed an ICC ¼ 0.98, SEM ¼ 10.7 Nm, and a MDC90 of 25.0 Nm in 20 individuals with radiographic knee OA 20 .…”

“…In young healthy individuals assessed over several days, average quadriceps power measured with a dynamometer displayed good-to-excellent between-session ICCs 14,15 . When tested on separate occasions 1 week apart, average quadriceps power displayed ICCs ¼ 0.92e0.94 in 18 adults with mild symptomatic knee OA 19 , and peak power exhibited an ICC ¼ 0.82, SEM ¼ 9.9 W and MDC90 ¼ 23 W in 20 patients with advanced hip or knee OA 23 . The ICCs for quadriceps power obtained in the current study are similar.…”
