Foot & Ankle Research

The Department of Biomechanics has expanded our research efforts to the lower extremities, focusing on how surgical adjustments of the foot and ankle structures affect function. Recently, the Foot & Ankle research group has developed a robotic gait simulator that allows for investigation of intrinsic foot and ankle joint biomechanics during simulated tasks such as walking. This development will contribute to the understanding of how structure influences normal hindfoot function. Additionally, the simulator will serve as an instrumental tool in the evaluation of various surgical techniques aimed at the correction of foot and ankle deformities. Our team aims to translate the findings gathered through experimental simulator and computational models into clinically relevant tools that will improve patient outcomes.

Current Projects

  • A biomechanical evaluation of total ankle arthroplasty as treatment options for end-stage ankle arthritis utilizing robotic gait simulator
  • Function assessment of ankle arthrodesis (fusion) and its effect on adjacent joint kinematics during simulated walking
  • Investigation of ultrasound shear-wave elastography as imaging modality to determine Achilles tendon material properties, degree of degeneration, and to predict risk of tendon rupture
