Predictive simulation of human walking has great potential in clinical motion analysis and rehabilitation engineering assessment, but large computational cost and reliance on measurement data to provide initial guess have limited its wide use. We dev... Read More about A three-dimensional whole-body model to predict human walking on level ground.

A fast inverse dynamics model of walking for use in optimisation studies (2016)
Journal Article
Salehi, S., Ren, L., & Howard, D. (2016). A fast inverse dynamics model of walking for use in optimisation studies. Computer Methods in Biomechanics and Biomedical Engineering, 19(11), 1201-1209. https://doi.org/10.1080/10255842.2015.1124267

Computer simulation of human gait, based on measured motion data, is a well-established technique in biomechanics. However, optimisation studies requiring many iterative gait cycle simulations have not yet found widespread application because of thei...

The strengths and weaknesses of inverted pendulum models of human walking (2014)
Journal Article
McGrath, M., Howard, D., & Baker, R. (2015). The strengths and weaknesses of inverted pendulum models of human walking. Gait & Posture, 41(2), 389-394. https://doi.org/10.1016/j.gaitpost.2014.10.023

An investigation into the kinematic and kinetic predictions of two ‘inverted pendulum’ (IP) models of gait was undertaken. The first model consisted of a single leg, with anthropometrically correct mass and moment of inertia, and a point mass at th...

This study investigated the effects of the finger extensor mechanism on the bone-to-bone contact forces at the interphalangeal and metacarpal joints and also on the forces in the intrinsic and extrinsic muscles during finger pressing. This was done w... Read More about Biomechanical analysis of the human finger extensor mechanism during isometric pressing.

The effects of transverse rotation angle on compression and effective lever arm of prosthetic feet during simulated stance (2012)
Journal Article
Major, M., Howard, D., Jones, R., & Twiste, M. (2012). The effects of transverse rotation angle on compression and effective lever arm of prosthetic feet during simulated stance. Prosthetics and Orthotics International, 36(2), 231-235. https://doi.org/10.1177/0309364611435996

Background and Aim: Unlike sagittal plane prosthesis alignment, few studies have observed the effects of transverse plane alignment on gait and prosthesis behaviour. Changes in transverse plane rotation angle will rotate the points of loading on the...

A generic analytical foot rollover model for predicting translational ankle kinematics in gait simulation studies (2010)
Journal Article
Ren, L., Howard, D., Ren, L., Nester, C., & Tian, L. (2010). A generic analytical foot rollover model for predicting translational ankle kinematics in gait simulation studies. Journal of Biomechanics, 43(2), 194-202. https://doi.org/10.1016/j.jbiomech.2009.09.027

The objective of this paper is to develop an analytical framework to representing the ankle-foot kinematics by modelling the foot as a rollover rocker, which cannot only be used as a generic tool for general gait simulation but also allows for case-s...
