Functional electrical stimulation (FES) applied to the common peroneal nerve is
commonly prescribed to correct both equinus and excessive foot inversion in swing
and initial contact. This paper presents the development of a simple shoe model,
to allow quantification of 3-D shoe (foot and footwear) kinematics in clinical
situations when footwear is required, e.g. with FES systems requiring
footswitches. To preliminarily validate the shoe model, barefoot 'normal' adult
data (n=11) processed using validated 3-D foot models, were reprocessed with the
shoe model. Outputs were compared through calculation of waveform similarity and
correlation. Clinical utility of the shoe model is demonstrated through the
presentation of 3-D shoe kinematics, calculated from a cohort of existing
unilateral common peroneal FES users (n=16), both with and without FES. A trend
of reduced inversion at mid-swing and initial contact was seen, although this was
not found to be statistically significant (p</=0.0125).
The shoe model was found
to be practical to use in a clinical environment, and has potential to contribute
to the evidence base for interventions such as common peroneal FES.
