A cam-displacement transducer device for measuring bi plane prosthetic motion (2004)
Journal Article
Twiste, M., Rithalia, S., & Kenney, L. (2004). A cam-displacement transducer device for measuring bi plane prosthetic motion. Medical Engineering and Physics, 26(4), 335-340. https://doi.org/10.1016/j.medengphy.2004.01.002

An electromechanical system is described that comprises a cam and two linear displacement transducers for measuring two-degree of freedom. This is aimed at quantifying the extent and pattern of both transverse rotation and longitudinal translation...

An implantable two channel drop foot stimulator: initial clinical results (2002)
Journal Article
Kenney, L., Bultstra, G., Buschman, R., Taylor, P., Mann, G., Hermens, H., …Hobby, J. (2002). An implantable two channel drop foot stimulator: initial clinical results. Artificial Organs, 26(3), 267-270. https://doi.org/10.1046/j.1525-1594.2002.06949.x

This article reports preliminary results of pilot studies of a new implantable two channel drop foot stimulator. The stimulator consists of an externally worn transmitter inductively coupled to an implanted receiver unit located in the lower leg, lat...

A comparison of feature extraction methods for the classification of dynamic activities from accelerometer data
Journal Article
Preece, S., Goulermas, J., Kenney, L., & Howard, D. A comparison of feature extraction methods for the classification of dynamic activities from accelerometer data. IEEE Transactions on Biomedical Engineering, 56, 871-879

Driven by the demands on healthcare resulting from the shift toward more sedentary lifestyles, considerable effort has been devoted to the monitoring and classification of human activity. In previous studies, various classification schemes and featur... Read More about A comparison of feature extraction methods for the classification of dynamic activities from accelerometer data.

Predicting lower limb joint kinematics using wearable motion sensors
Journal Article
Findlow, A., GOULERMAS, J., Nester, C., Howard, D., & Kenney, L. Predicting lower limb joint kinematics using wearable motion sensors. Gait & Posture, 28(1), 120-126. https://doi.org/10.1016/j.gaitpost.2007.11.001

The aim of this study was to estimate sagittal plane ankle, knee and hip gait kinematics using 3D angular velocity and linear acceleration data from motion sensors on the foot and shank. We explored the accuracy of intra-subject predictions (i.e., wh... Read More about Predicting lower limb joint kinematics using wearable motion sensors.

Why doesn’t a prosthetic hand always do what it’s told?
Journal Article
Chadwell, A., Prince, M., Head, J., Galpin, A., Thies, S., & Kenney, L. (in press). Why doesn’t a prosthetic hand always do what it’s told?. Frontiers for Young Minds,

There are online videos which appear to show electrically-powered prosthetic hands to be nearperfect replacements for a missing hand (e.g. https://youtu.be/F_brnKz_2tI). However, for many users, the reality can be different. Prosthetic hands don’t a... Read More about Why doesn’t a prosthetic hand always do what it’s told?.

A novel energy storage and return prosthetic ankle using cams and miniature hydraulics
Journal Article
Pace, A., Gardiner, J., Kenney, L., & Howard, D. (in press). A novel energy storage and return prosthetic ankle using cams and miniature hydraulics. IEEE Transactions on Neural Systems and Rehabilitation Engineering,

A novel design for an energy-storage-and-return (ESR) prosthetic ankle is described, based on simple miniature hydraulics. The aim is to overcome the weaknesses of prosthetic feet currently on the market and also previous research attempts, which are...
