Automated detection of instantaneous gait events using time frequency analysis and manifold embedding (2013)
Journal Article
using time frequency analysis and manifold embedding. IEEE Transactions on Neural Systems and Rehabilitation Engineering, 21(6), 908-915. https://doi.org/10.1109/TNSRE.2013.2239313

Accelerometry is a widely used sensing modality
in human biomechanics due to its portability, non-invasiveness, and accuracy. However, difficulties lie in signal variability and interpretation in relation to biomechanical events. In walking, heel st... Read More about Automated detection of instantaneous gait events using time frequency analysis and manifold embedding.

Background
Previous studies of commercially-available trans-tibial prosthetic components have been unable to provide clear insight into the relationships between prosthetic mechanical properties and user performance (i.e., gait quality and energy ex...

Automatic detection of lift-off and touch-down of a pick-up walker using 3D kinematics (2013)
Journal Article
Grootveld, L., Thies, S., Ogden, D., Howard, D., & Kenney, L. (2014). Automatic detection of lift-off and touch-down of a pick-up walker using 3D kinematics. Medical Engineering and Physics, 36(2), 255-260. https://doi.org/10.1016/j.medengphy.2013.08.008

Walking aids have been associated with falls and it is believed that incorrect use limits their usefulness. Measures are therefore needed that characterize their stable use and the classification of key events in walking aid movement is the first ste...

Bernstein’s levels of construction of movements applied to upper limb prosthetics (2012)
Journal Article
applied to upper limb prosthetics. Journal of Prosthetics and Orthotics, 24(2), 67-76

This article addresses the neuromotor control processes underlying the use of an upper limb prosthesis. Knowledge of these processes is used to make recommendations as to how prostheses and prosthesis training should develop to advance the functional...

Stance phase mechanical characterization of transtibial prostheses distal to the socket : a review (2012)
Journal Article

Achieving the required functionality of a trans-tibial prosthesis during the stance phase
of gait (e.g., shock absorption, close to normal roll-over characteristics, and smooth
transition into swing) depends on the “Amputee Independent Prosthesis P... Read More about Stance phase mechanical characterization of transtibial prostheses distal to the socket : a review.

Effects of ramp negotiation, paving type and shoe sole geometry on toe clearance in young adults (2011)
Journal Article
Thies, S., Jones, R., Kenney, L., Howard, D., & Baker, R. (2011). Effects of ramp negotiation, paving type and shoe sole geometry on toe clearance in young adults. Journal of Biomechanics, 44(15), 2679-2684. https://doi.org/10.1016/j.jbiomech.2011.07.027

Trips are a major cause of falls and result from involuntary contact of the foot with the ground during the swing phase of gait. Adequate toe clearance during swing is therefore crucial for safe locomotion. To date, little is known about the effects...
