The aim of our study was to assess the measurement reproducibility of the amputated defrosted foot compression test data at different loading rate. The foot specimen used for testing was from a female. Compressive tests were done on a 25 kN force Tinius Olsen H25K-T testing machine. Defrosted foot specimen was repeatedly loaded at a different rate 25 mm/min, 50 mm/min, 100 mm/min and 500 mm/min. The Intraclass Correlation Coefficient was calculated to assess the measurement reliability of foot force-displacement curves at each loading rate. The measures of foot displacement taken from the repeated compression test had a very high level of agreement at each compression rate.
