Association between foot types defined by static and dynamic measures, and the centre of pressure during gait (2014)
Journal Article
Liao, S., Javis, H., Liu, A., Nester, C., Bowden, P., Jones, R., & Xiong, K. (2014). Association between foot types defined by static and dynamic measures, and the centre of pressure during gait. Journal of Foot and Ankle Research, 7(S1), A55-A55. https://doi.org/10.1186/1757-1146-7-S1-A55

Foot types (e.g. pronated, supinated foot) are used for clinical reasoning [1] and widely assumed to be related to centre of pressure (COP) patterns [2, 3]. Specifically, a pronated foot will demonstrate a medially deviated COP. It follows that COP c...

Early observations of the effects of lateral wedge orthoses on lower limb muscle length and potential for exacerbating spasticity (2010)
Journal Article
