Chapman, J., Preece, S., Nester, C., Braunstein, B., Höhne, A., & Brüggermann, G. (2014). Evaluating the effect of apex position and rocker in curved rocker shoes. Journal of Foot and Ankle Research, 7(S1), A66-A66. https://doi.org/10.1186/1757-1146-7-S1-A66

Curved rocker shoes are designed with a contoured outsole which can be characteristics by three principle design features: rocker angle, apex angle and apex position. Although these shoes are routinely prescribed to reduce in-shoe pressure in patient... Read More about Evaluating the effect of apex position and rocker in curved rocker shoes.

Background
Although approximately one-third of stroke survivors suffer abnormal foot posture and this can influence mobility, there is very little objective information regarding the foot and ankle after stroke.

Objective
As part of a programme... Read More about The effect of stroke on foot kinematics and the functional consequences.

Effect of rocker shoe design features on forefoot plantar pressures in people with and without diabetes (2013)
Journal Article

Background: There is no consensus on the precise rocker shoe outsole design that will optimally reduce plantar pressure in people with diabetes. This study aimed to understand how peak plantar pressure is influenced by systematically varying three de...

Foot posture after stroke : frequency, nature and clinical significance (2011)
Journal Article

Objectives: clinical convention suggests that foot posture and movements are adversely affected by stroke and cause walking difficulties but there is little objective data to support or refute these beliefs. This study explores static foot posture in... Read More about Foot posture after stroke : frequency, nature and clinical significance.

Automatic identification of gait events using an instrumented sock (2011)
Journal Article
instrumented sock. Journal of NeuroEngineering and Rehabilitation, 8, 32. https://doi.org/10.1186/1743-0003-8-32

Background: textile-based transducers are an emerging technology in which piezo-resistive properties of materials
are used to measure an applied strain. By incorporating these sensors into a sock, this technology offers the
potential to detect crit... Read More about Automatic identification of gait events using an instrumented sock.

Early observations of the effects of lateral wedge orthoses on lower limb muscle length and potential for exacerbating spasticity (2010)
Journal Article
spasticity. Prosthetics and Orthotics International, 34(3), 319-326. https://doi.org/10.3109/03093646.2010.504976

Lateral wedge orthoses are often prescribed to correct varus deformity after stroke. Spasticity is implicated in varus deformity and is caused by velocity-related muscle length changes, so a lateral wedge may affect spasticity by manipulating foot an...

Reproducibility of MUAP properties in array surface EMG recordings of the upper trapezius and sternocleidomastoid muscle (2009)
Journal Article

The use of array surface EMG recordings for detailed assessment of motor control and muscle properties is increasing. Motor unit action potentials (MUAPs) and their properties can be extracted from these recordings. The objective of this study was to...

Variation in pelvic morphology may prevent the identification of anterior pelvic tilt (2008)
Journal Article

Pelvic tilt is often quantified using the angle between the horizontal and a line connecting the anterior superior iliac spine (ASIS) and the posterior superior iliac spine (PSIS). Although this angle is determined by the balance of muscular and liga... Read More about Variation in pelvic morphology may prevent the identification of anterior pelvic tilt.

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...
