Abstract:

Background: Test-retest strength, reliability of the Electronic Push/Pull Dynamometer (EPPD) in the measurement of the extensor and flexor muscles on a new constructed chair. Objective: The objective of the study was to assess the reliability of Electronic Push/Pull Dyna- mometer in the measurement of the knee flexion and extension at 90�? and 60�? on a new constructed chair. Aim: To assess reliability of Elec- tronic Push/Pull Dynamometer in the measurement of the knee flexion and extension at 90�? and 60�? on a new constructed chair. Design: A test-retest reliability study. Subjects: One hundred healthy students, male and female (mean age, 21 y). Methods: Maximum isometric strength of the quadriceps and hamstring muscle groups was measured using the EPPD were recorded at 60�? and 90�? for 3 trials on 2 occasions. Reliability was assessed with the Intraclass correla- tion coefficient (ICC), mean and standard deviation (SD) of measurements, and smallest real differences were calculated for the maximum and for the mean and work of the 3 repetitions. Results: Mean strength ranged from 50.44 kg for knee flexion to 55.76 kg for knee extension 50.44 kg to 61.98 kg at 90�? hip flexion. Test-retest reliability Intraclass correlation coeffi- cients (ICCs) ranged from 0.85 to 0.99. ICCs for test-retest reliability ranged from 0.780 to 0.998. Conclusions: The results of the reliability study indicate that the EPPD in reliable dynamometer to use in de- termining lower limb muscle force production. It can be used to measure disease progression and to evaluate changes in knee extension and flexion strength at the individual patient level.
