Table 1 Average spatiotemporal, ankle kinematic and dynamic parameters during six steps for arthrodesis, total ankle replacement (TAR) and comparison with Healthy subject (intra-trial confidential coefficient comprised between 0.93 and 0.98 for the left joints side and between 0.96 and 0.99 for the right joints side)

From: Comparison of total ankle replacement and ankle arthrodesis in patients with haemophilia using gait analysis: two case reports
