Characterisation of rollator use using inertial sensors (2016)
Journal Article
Cheng, T., Kenney, L., Amor, J., Thies, S., Costamagna, E., James, C., & Holloway, C. (2016). Characterisation of rollator use using inertial sensors. Healthcare Technology Letters, 3(4), https://doi.org/10.1049/htl.2016.0061

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
Gardiner, J., Gunarathne, N., Howard, D., & Kenney, L. (2016). Crowd-sourced amputee gait data : a feasibility study using YouTube videos of unilateral trans-femoral gait. PLoS ONE, 11(10), e0165287. https://doi.org/10.1371/journal.pone.0165287

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...

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.

The reality of myoelectric prostheses : understanding what makes these devices difficult for some users to control (2016)
Journal Article
control. Frontiers in Neurorobotics, 10(7), https://doi.org/10.3389/fnbot.2016.00007

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...

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...
