Journal Article
Chadwell, A., Prince, M., Head, J., Galpin, A., Thies, S., & Kenney, L. (2022). Why does my prosthetic hand not always do what it is told?. Frontiers for Young Minds, 10, https://doi.org/10.3389/frym.2022.786663

There are online videos that appear to show electrically powered prosthetic (artificial) hands to be near-perfect replacements for a missing hand. However, for many users, the reality can be quite different. Prosthetic hands do not always respond as... Read More about Why does my prosthetic hand not always do what it is told?.

The impact of limited prosthetic socket documentation : a researcher perspective (2022)
Journal Article
Olsen, J., Turner, S., Chadwell, A., Dickinson, A., Ostler, C., Armitage, L., …Day, S. (2022). The impact of limited prosthetic socket documentation : a researcher perspective. Frontiers in Rehabilitation Sciences, 3, 853414. https://doi.org/10.3389/fresc.2022.853414

The majority of limb prostheses are socket mounted. For these devices, the socket is essential for adequate prosthetic suspension, comfort, and control. The socket is unique among prosthetic components as it is not usually mass-produced and must inst... Read More about The impact of limited prosthetic socket documentation : a researcher perspective.

An evaluation of contralateral hand involvement in the operation of the Delft Self-Grasping Hand, an adjustable passive prosthesis (2021)
Journal Article
Chadwell, A., Chinn, N., Kenney, L., Karthaus, Z., Mos, D., & Smit, G. (2021). An evaluation of contralateral hand involvement in the operation of the Delft Self-Grasping Hand, an adjustable passive prosthesis. PLoS ONE, 16(6), e0252870. https://doi.org/10.1371/journal.pone.0252870

The Delft Self-Grasping Hand is an adjustable passive prosthesis operated using the concept of tenodesis (where opening and closing of the hand is mechanically linked to the flexion and extension of the wrist). As a purely mechanical device that does... Read More about An evaluation of contralateral hand involvement in the operation of the Delft Self-Grasping Hand, an adjustable passive prosthesis.

Addressing unpredictability may be the key to improving performance with current clinically prescribed myoelectric prostheses (2021)
Journal Article
Chadwell, A., Kenney, L., Thies, S., Head, J., Galpin, A., & Baker, R. (2021). Addressing unpredictability may be the key to improving performance with current clinically prescribed myoelectric prostheses. Scientific reports, 11, 3300. https://doi.org/10.1038/s41598-021-82764-6

The efferent control chain for an upper-limb myoelectric prosthesis can be separated into 3 key areas: signal generation, signal acquisition, and device response. Data were collected from twenty trans-radial myoelectric prosthesis users using their o...

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...
