Objectives To measure passive musculoarticular ankle stiffness ( PMAAS ) and its intra‐ and interday reliability in adult control subjects without ankle disorders. We also sought to quantify PMAAS in children, adolescents and young adults with haemophilia ( CAA wH) taking into account the accurate tibiotalar and subtalar joints structural status obtained by magnetic resonance imaging ( MRI ). Methods We included 23 CAA wH and 23 typically developing boys ( TDB ) matched by age, weight and height, along with 25 healthy volunteers for reliability assessment. All CAA wH underwent bilateral ankle MRI , with anatomical status assessed using the International Prophylaxis Study Group MRI scale. All CAA wH underwent PMAAS testing for both sides randomly vs the dominant side ( DS ) in TDB s. For assessing viscous stiffness ( VS ) and elastic stiffness ( ES ), eight different oscillation frequencies were randomly repeated three times for each subject. Results Good‐to‐excellent intra‐ and interday reliability was observed for ES and VS variables. No relevant differences were observed between the ankle viscoelastic properties in CAA wH without joint damage and matched TDB s, whereas the study revealed significantly increased ES in the affected ankles of CAA wH with severe unilateral joint involvement compared to the non‐affected joint. Conclusion This study confirmed increased ES in the severely affected ankles of CAA wH compared to non‐affected sides. No differences in the ankle viscoelastic properties of CAA wH with or without joint damage were observed, however, compared to matched TDB .
