The design, development and evaluation of an array-based FES system with automated setup for the correction of drop foot (2002)
Presentation / Conference
Kenney, L., Heller, B., Barker, A., Reeves, M., Healey, J., Good, T., …Howard, D. (2002, August). The design, development and evaluation of an array-based FES system with automated setup for the correction of drop foot. Presented at 9th IFAC Symposium on Biological and Medical Systems, Berlin, Germany, Berlin, Germany

Functional electrical stimulation has been shown to be a safe and effective means of correcting drop foot of central neurological origin. However, despite recent technological advances, the set-up of surface stimulators remains a challenge for many...

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.

Whole body inverse dynamics over a complete gait cycle based only on measured kinematics
Journal Article
Ren, L., Jones, R., & Howard, D. Whole body inverse dynamics over a complete gait cycle based only on measured kinematics. Journal of Biomechanics, 41(12), 2750-2759. https://doi.org/10.1016/j.jbiomech.2008.06.001

This paper presents a three-dimensional (3D) whole body multi-segment model for inverse dynamics analysis over a complete gait cycle, based only on measured kinematic data. The sequence of inverse dynamics calculations differs significantly from the... Read More about Whole body inverse dynamics over a complete gait cycle based only on measured kinematics.

Kinematic design of crab-like legged vehicles
Journal Article

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...
