Journal Article
Hussaini, A., Kyberd, P., Mulindwa, B., Ssekitoleko, R., Keeble, W., Kenney, L., & Howard, D. (2023). 3D Printing in LMICs: functional design for upper limb prosthetics in Uganda. Prosthesis, 5(1), 130-147. https://doi.org/10.3390/prosthesis5010011

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...

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
Thies, S., Russell, R., Al-ani, A., Belet, T., Bates, A., Costamagna, E., …Howard, D. (2020). An investigation of the effects of walking frame height and width on walking stability. Gait & Posture, 82, 248-253. https://doi.org/10.1016/j.gaitpost.2020.09.017

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
Prince, M., Kenney, L., & Howard, D. (2020). A pin-array method for capturing tissue deformation under defined pressure distributions and its application to prosthetic socket design. Medical Engineering and Physics, 84, 136-143. https://doi.org/10.1016/j.medengphy.2020.08.003

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
Chadwell, A., Kenney, L., Howard, D., Ssekitoleko, R., Nakandi, B., & Head, J. (2020). Evaluating reachable workspace and user control over prehensor aperture for a body-powered prosthesis. IEEE Transactions on Neural Systems and Rehabilitation Engineering, 28(9), 2005-2014. https://doi.org/10.1109/TNSRE.2020.3010625

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...

Are older people putting themselves at risk when using their walking frames? (2020)
Journal Article
Thies, S., Bates, A., Costamagna, E., Kenney, L., Granat, M., Webb, J., …Dawes, H. (2020). Are older people putting themselves at risk when using their walking frames?. BMC Geriatrics, 20(1), 90. https://doi.org/10.1186/s12877-020-1450-2

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?.

A three-site clinical feasibility study of a flexible functional electrical stimulation system to support functional task practice for upper limb recovery in people with stroke (2019)
Journal Article

A three-site clinical feasibility study of a flexible functional electrical stimulation system to support functional task practice for upper limb recovery in people with stroke. Frontiers in Neurology, 10(227), https://doi.org/10.3389/fneur.2019.00227

Introduction: Of those people who survive a stroke, only between 40 and 70% regain upper limb dexterity. A number of reviews have suggested that functional electrical stimulation (FES) may have a beneficial effect on upper limb motor recovery. In lig...

An investigation into the effects of, and interaction between, heel height and shoe upper stiffness on plantar pressure and comfort (2019)
Journal Article
Melvin, J., Price, C., Preece, S., Nester, C., & Howard, D. (2019). An investigation into the effects of, and interaction between, heel height and shoe upper stiffness on plantar pressure and comfort. Footwear Science, 11(1), 25-34. https://doi.org/10.1080/19424280.2018.1555862

High heeled shoes remain popular, nevertheless it is not clear what influence manipulating characteristics of this footwear has on their functioning. It is accepted that shoe features other than heel height can affect plantar pressures. However, few...
