Gait Research

Objectives

The Auckland Bioengineering Institute Gait Research Group aims to advance musculoskeletal modelling techniques to provide new insights into the biomechanics of human walking.

Medical images are used to develop anatomically-based models of individual subjects. The 3D models are simulated during walking based on external measurements from gait analysis. Clinically important parameters are analysed in collaboration with orthopaedic surgeons to assist in the assessment of patients with neuromuscular disorders such as cerebral palsy. Muscle and joint function during walking are visualised for further use in medical education and training.

Current projects

  • Development of a software tool for improved clinical assessment of normal and pathological gait
  • Finite element analyses of hip joint loading during walking to gain new insights into the development of hip deformities
  • Advanced modelling of knee joint dynamics for better injury management and prevention
  • Development of an interactive, web-based teaching platform for medical education and training
