Journal Article
Chadwell, A., Kenney, L., Granat, M., Thies, S., Head, J., Galpin, A., & Baker, R. (2018). Upper limb activity in myoelectric prosthesis users is biased towards the intact limb and appears unrelated to goal-directed task performance. Scientific reports, 8, #11084. https://doi.org/10.1038/s41598-018-29503-6

Studies of the effectiveness of prosthetic hands involve assessing user performance on functional tasks in the lab/clinic, sometimes combined with self-report of real-world use. In this paper we compare real-world upper limb activity between a group...

Performance of optimised prosthetic ankle designs that are based on a hydraulic variable displacement actuator (VDA) (2017)
Journal Article

Current energy storage and return (ESR) prosthetic feet only marginally reduce the cost of amputee locomotion compared to basic solid ankle cushioned heel (SACH) feet, possibly due to their lack of push-off at the end of stance. To our knowledge,... Read More about Performance of optimised prosthetic ankle designs that are based on a hydraulic variable displacement actuator (VDA).

A generalizable methodology for stability assessment of walking aid users (2017)
Journal Article

To assist balance and mobility, older adults are often prescribed walking aids. Nevertheless, surprisingly their use has been associated with increased falls-risk. To address this finding we first need to characterise a person’s stability while using... Read More about A generalizable methodology for stability assessment of walking aid users.
