Purpose: This study aimed to determine whether there are differences in subtalar joint range of motion (ROM) when using different measurement methods, and to determine inter- and intra-rater reliability of goniometry as used in clinical setting. Methods: Subjects were thirty-one healthy males and females (sixty-two ankles) living in Korea. Three raters with different clinical experiences measured inversion and eversion range of motion of the subtalar joint two times. Measurements were done with subjects prone (open kinetic chain) and standing (closed kinetic chain). Rater and measurement methods were based on analyzing differences in range of motion. Intra-class correlation coefficients (ICCs) were calculated to determine intra-rater and inter-rater reliability. Results: Mean subtalar jont range of motion for inversion ranged from $9.31^{circ}$ to $11.94^{circ}$ for eversion, it ranged from $6.73^{circ}$ to $9.20^{circ}$. The differences in ROM between raters and between measurement methods were significant (p<0.01). The ICCs for interrater reliability ranged from $0.02^{circ}$ to $0.20^{circ}$ for inversion and from $0.23^{circ}$ to $0.39^{circ}$ for eversion. Intrarater reliability ranged from $0.32^{circ}$ to $0.78^{circ}$ for inversion and from $0.45^{circ}$ to $0.73^{circ}$ for eversion. Conclusion: Subtalar joint inversion and eversion ROM show differences for measurement methods low reliability between different raters, and low to high intra-rater reliability within sessions.
