• Aim– Investigate if using prosthetic foot with hydraulically
controlled articulating ankle that allows foot to be relatively dorsiflexed at toe-off and throughout swing increases minimum toe clearance (MTC).
• Relevance– Most clinically available prosthetic feet have rigid
attachment or incorporate “ankle” device allowing elastic articulation during stance, with foot returning to “neutral” position at toe-off.

Method
• 21 people with unilateral transtibial amputation completed overground walking trials using their habitual prosthetic foot with rigid or elastic articulating attachment and a foot with a hydraulic ankle attachment (hyA-F).
• MTC and other kinematic variables were assessed across multiple trials.

Results• When using hyA-F:– Mean MTC increased on both limbs. • On prosthetic limb, this was partly due to device being in its
fully dorsiflexed position at toe-off, which reduced the “toes down” foot angle throughout swing.
– Walking speed increased and was associated with greater swing-limb hip flexion on prosthetic side, which may have contributed to increased mean MTC.
– Variability in MTC increased on prosthetic side, but did not increase risk of tripping.

Conclusion
• Using hyA-F could increase MTC and walking speed in persons with amputation.
