Characterisation of rollator use using inertial sensors (2016)
Journal Article

The use of walking aids is prevalent among older people and people with mobility impairment. Rollators are designed to support outdoor mobility and require the user to negotiate curbs and slopes in the urban environment. Despite the prevalence of rol...

Crowd-sourced amputee gait data : a feasibility study using YouTube videos of unilateral trans-femoral gait (2016)
Journal Article

Collecting large datasets of amputee gait data is notoriously difficult. Additionally, collecting data on less prevalent amputations or on gait activities other than level walking and running on hard surfaces is rarely attempted. However, with the we...

A review of the design and clinical evaluation of the ShefStim array-based functional electrical stimulation system (2016)
Journal Article

Functional electrical stimulation has been shown to be a safe and effective means of correcting foot drop of central neurological origin. Current surface-based devices typically consist of a single channel stim- ulator, a sensor for determining gait...

Dealing with time-varying recruitment and length in Hill-type muscle models (2016)
Journal Article
Hamouda, A., Kenney, L., & Howard, D. (2016). Dealing with time-varying recruitment and length in Hill-type muscle models. Journal of Biomechanics, 49(14), 3375-3380. https://doi.org/10.1016/j.jbiomech.2016.08.030

Hill-type muscle models are often used in muscle simulation studies and also in the design
and virtual prototyping of functional electrical stimulation systems. These models have to
behave in a sufficiently realistic manner when recruitment level a... Read More about Dealing with time-varying recruitment and length in Hill-type muscle models.

Functional electrical stimulation versus ankle foot orthoses for foot-drop : a meta-analysis of orthotic effects (2016)
Journal Article

Objective: To compare the effects on walking of functional
electrical stimulation (FES) and ankle foot orthoses for footdrop of central neurological origin, assessed in terms of unassisted walking behaviours compared with assisted walking following...

The reality of myoelectric prostheses : understanding what makes these devices difficult for some users to control (2016)
Journal Article

Users of myoelectric prostheses can often find them difficult to control. This can lead to passive-use of the device or total rejection, which can have detrimental effects on the contralateral limb due to overuse.
Current clinically available prosth... Read More about The reality of myoelectric prostheses : understanding what makes these devices difficult for some users to control.

A novel method of using accelerometry for upper limb FES control (2016)
Journal Article

This paper reports on a novel approach to using a 3-axis accelerometer to capture body segment angle for upper limb functional electrical stimulation (FES) control. The approach calculates the angle between the accelerome... Read More about A novel method of using accelerometry for upper limb FES control.

The effects of prosthetic ankle stiffness on stability of gait in people with trans-tibial amputation (2016)
Journal Article

The ability to control balance during walking is a critical precondition for minimizing fall risk, but is compromised in persons with lower-limb loss due to reduced sensory feedback mechanisms and inability to actively modulate prosthesis mechanical...

Transtibial amputee gait efficiency : energy storage and return versus solid ankle cushioned heel prosthetic feet (2016)
Journal Article

Energy storage and return (ESR) feet have long been assumed to promote metabolically efficient amputee gait. However, despite being prescribed for approximately thirty years, there is limited evidence that they achieve this desired function. Here, we...
