Novel in-shoe temperature sensor located underfoot optimized by plantar pressure found rate of temp increase following donning of footwear is higher in people with (early stage) diabetes. 🔥🦶⏫ doi.org/10.3390/s21051… via MDPI

Professor at UNC/NC State, Jacque Cole, is excited about the new field of mechanomics! With advancements in mechanomics, biomechanists will be able to use this knowledge to improve the field of biomechanics. #future #biomechanics #podcast

Plantar skin properties had more influence than sock/interface. No trend in skin hydration across the foot (6 sites) or individuals [multiple factors proposed]. ⬆️ hydration tends to ⬆️ friction force. [2015] #Friction #TissueMech sciencedirect.com/science/articl… via Elsevier | ScienceDirect

The location of peak forefoot pressure and shear overlapped in a pilot study of people with #Diabetes. Peak pressure happened before peak shear. Leading to a press and stretch which may damage tissue. [2002] #Gait #Shear sciencedirect.com/science/articl… via G&P

FEA shows sock stiffness (weave) and sock outer friction (coating) influence shear measurement accuracy. Optimal sock for measurement is low stiffness and high outer CoF. Reducing skin-sock CoF may reduce tissue shear [2021] #Shear #Gait sciencedirect.com/science/articl… via Journal of Biomechanics

A model of foot-sock-insole interaction shows plantar pressure is constant between barefoot & sock but shear is significantly lower (~9x at forefoot). +Varying friction arrangement affects where slip occurs. [2006] #FEA #Shear #Friction sciencedirect.com/science/articl… via J Clinical Biomech

#Friction #Gait hydration ⬆️ frictional force [Tasron 2015] Friction affected by local tissue stiffness [Abdel-Aal 2017] Peak pressure & shear can coincide [Perry 2002] Sock affects shear/slip not pressure [Dai 2006] Measure with low stiff' & high outer CoF socks [Tiell 2021]

Providing people at risk of diabetic ulceration with custom indoor footwear improves adherence (time wearing footwear) from baseline - unknown cost/benefit or longer term impact. [Symp Abstract] [2021] #Footwear #Diabetes doi.org/10.1080/194242… via Footwear Science

Collagen within skin cells (rats) is a woven mesh (in plate shape) which can respond (change shape) under stretching force in multiple directions. Mesh shape may define proteoglycans profile and thus manage cell-cell interaction/function. [2013] #Skin ncbi.nlm.nih.gov/pmc/articles/P…

Wonderful editorial by our #EditorinChief Amit Gefen, including prospectives from the original Editorial Board! As written by Mark Pearcy: "It is interesting to reflect that Clinical Biomechanics has been a constant companion, source of knowledge... throughout my career."
