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 novel hydraulic energy-storage-and-return prosthetic ankle : design, modelling and simulation (2020)
Thesis
Pace, A. A novel hydraulic energy-storage-and-return prosthetic ankle : design, modelling and simulation. (Thesis). University of Salford

In an intact ankle, tendons crossing the joint store energy during the stance phase of walking prior to push-off and release it during push-off, providing forward propulsion. Most prosthetic feet currently on the market – both conventional and ener... Read More about A novel hydraulic energy-storage-and-return prosthetic ankle : design, modelling and simulation.

Using magneto-inertial-measurement-units to track upper-limb movement during rehabilitation (2020)
Thesis
Al-ani, A. Using magneto-inertial-measurement-units to track upper-limb movement during rehabilitation. (Thesis). University of Salford

Functional Electrical Stimulation (FES) can be used to support upper-limb rehabilitation after a stroke. A key aspect of FES control and also patient monitoring is the automatic tracking of upper-limb motion during intensive and functional practise o...

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...

The influence of the mechanical properties of trans-tibial prostheses on amputee performance (2010)
Thesis
Major, M. The influence of the mechanical properties of trans-tibial prostheses on amputee performance. (Thesis). Salford : University of Salford

Achieving the required functionality of a trans-tibial prosthesis during the stance phase of gait (e.g., shock absorption, close to normal roll-over characteristics, and smooth transition into swing) depends on the "Amputee Independent Prosthesis P...
