Effect of a Prosthetic Foot with a Hydraulic Ankle Unit on the Contralateral Foot Peak Plantar Pressures in Individuals with Unilateral Amputation

IntroductionSince their release, prosthetic feet with integrated hydraulic ankle units have proved a popular prescription choice among individuals with lower-limb amputation. This study evaluates the effect of including this type of prosthetic foot on the peak plantar pressures of the patient’s contralateral foot. Case Description and MethodsPeak plantar pressures of 14 participants with established K3 activity levels were measured before and after the addition of a prosthetic foot with hydraulic ankle unit using the Amcube pressure plate. ResultsThe results showed a statistically significant reduction in contralateral peak plantar pressures with the use of a prosthetic foot containing a hydraulic ankle unit. ConclusionsThe benefits of changing to a prescription including a foot with integrated hydraulic ankle unit can have significant effects on the forces acting on the remaining foot of an individual with amputation.
