Discomfort experienced during surface functional electrical stimulation (FES) is thought to be partly a result of localised high current density in the skin underneath the stimulating electrode. This paper describes a finite element (FE) model to pre... Read More about A finite element model to identify electrode influence on current distribution in the skin.

The influence of gluteus maximus on transverse plane tibial rotation (2008)
Journal Article

There is a common clinical belief that transverse plane tibial rotation is controlled by the rearfoot. Although distal structures may influence the motion of the tibia, transverse plane tibial rotation could be determined by the proximal hip musculat...

There is a dearth of information on navicular, cuboid, cuneiform and metatarsal kinematics during walking and our objective was to study the kinematic contributions these bones might make to foot function. A dynamic cadaver model of walking was used... Read More about In vitro study of foot kinematics using a dynamic walking cadaver model.

Foot kinematics during walking measured using bone and surface mounted markers (2007)
Journal Article

The aim was to compare kinematic data from an experimental foot model comprising four segments ((i) heel, (ii) navicular/cuboid (iii) medial forefoot, (iv) lateral forefoot), to the kinematics of the individual bones comprising each segment. The foot... Read More about Foot kinematics during walking measured using bone and surface mounted markers.

Predictive modelling of human walking over a complete gait cycle (2007)
Journal Article

An inverse dynamics multi-segment model of the body was combined with optimisation techniques to simulate normal walking in the sagittal plane on level ground. Walking is formulated as an optimal motor task subject to multiple constraints with minimi... Read More about Predictive modelling of human walking over a complete gait cycle.

Intrinsic foot kinematics measured in vivo during the stance phase of slow running (2007)
Journal Article

An accurate kinematic description of the intrinsic articulations of the foot during running has not previously been presented, primarily due to methodological limitations. An invasive method based upon reflective marker arrays mounted on intracortica... Read More about Intrinsic foot kinematics measured in vivo during the stance phase of slow running.

Invasive study of rearfoot, midfoot and forefoot kinematics during walking (2006)
Journal Article

There is a dearth of quality information on the kinematics of the mid and
forefoot during ambulation. We investigated the kinematics of the tibia, fibula,

during wa... Read More about Invasive study of rearfoot, midfoot and forefoot kinematics during walking.

Intrinsic foot motion measured in vivo during barefoot running (2006)
Journal Article

Knowledge of the natural range of motion of individual skeletal segments in
the foot during running is necessary for the construction of appropriate stability
parameters in athletic footwear. Globally restricting intrinsic motion of the foot
may r... Read More about Intrinsic foot motion measured in vivo during barefoot running.
