Can a novel set of handgrips on a walking frame increase stability and support users when transferring to/from a chair? (2025)
Journal Article

Introduction: One important aspect of walking aid use is transferring safely to the aid from sitting and transferring back to the chair after walking, since these activities have been associated with falls in older adults. Standard frames require the... Read More about Can a novel set of handgrips on a walking frame increase stability and support users when transferring to/from a chair?.

3D Printing in LMICs: functional design for upper limb prosthetics in Uganda (2023)
Journal Article

Meeting the needs of persons with upper limb loss in Uganda requires an understanding of
the needs and desires of the local population. The limitations of resources and accessibility for the
individual gave rise to a focused design methodology fo... Read More about 3D Printing in LMICs: functional design for upper limb prosthetics in Uganda.

Simulated performance of an energy storage and return prosthetic ankle based on cams and miniature hydraulics (2022)
Journal Article
Pace, A., Gardiner, J., Kenney, L., & Howard, D. (2022). Simulated performance of an energy storage and return prosthetic ankle based on cams and miniature hydraulics. IEEE Transactions on Medical Robotics and Bionics, https://doi.org/10.1109/TMRB.2022.3146628

Prosthetic feet are limited in their ability to mimic the energy-recycling behaviour of an intact ankle, negatively affecting lower-limb amputees’ gait in terms of metabolic cost and walking speed. To overcome these weaknesses, a novel prosthetic ank... Read More about Simulated performance of an energy storage and return prosthetic ankle based on cams and miniature hydraulics.

Effects of a modified passive socket system on short-term changes in residuum volume and comfort: A preliminary study in transtibial amputees (2021)
Journal Article

Effects of a modified passive socket system on short-term changes in residuum volume and comfort: A preliminary study in transtibial amputees. Prosthetics and Orthotics International, 46(1), 54-60. https://doi.org/10.1097/pxr.0000000000000053

Background: Changes in residuum volume are a common problem in lower-limb amputees during prosthesis usage, and can lead to poor suspension, impaired gait, and tissue damage. Residuum volume can be affected by the in-socket air pressure, which will i...

An investigation of the effects of walking frame height and width on walking stability (2020)
Journal Article

Background
Walking aids are designed for structural support during walking, however, surprisingly self-reported use of a walking aid (“Yes, I use one.”) has been identified as a risk factor for falling. Adjustment and design of walking aids may affe... Read More about An investigation of the effects of walking frame height and width on walking stability.

A pin-array method for capturing tissue deformation under defined pressure distributions and its application to prosthetic socket design (2020)
Journal Article

The Fit4Purpose project aims to develop upper limb prosthetic devices which are suitable for deployment in lower- and middle-income countries (LMIC's). Open-frame trans-radial socket designs are being considered, formed of several, linked components,...

Evaluating reachable workspace and user control over prehensor aperture for a body-powered prosthesis (2020)
Journal Article

Using a shoulder harness and control cable, a
person can control the opening and closing of a bodypowered prosthesis prehensor. In many setups the cable
does not pass adjacent to the shoulder joint center allowing
shoulder flexion on the prostheti... Read More about Evaluating reachable workspace and user control over prehensor aperture for a body-powered prosthesis.

Are older people putting themselves at risk when using their walking frames? (2020)
Journal Article

Background Walking aids are issued to older adults to prevent falls, however, paradoxically their use has been identified as a risk factor for falling. To prevent falls, walking aids must be used in a stable manner, but it remains unknown to what ext... Read More about Are older people putting themselves at risk when using their walking frames?.
