“…Temperature changes in response to walking may be monitored using either thermography, insoles, or flexible sensors (eg, smart socks). [57][58][59][60][61] These methods assume that increases in shear stress will increase thermal stress responses. 60,61 Such approaches can measure short-term acute increases in regional skin temperature of the foot in response to number of steps taken or in comparison to the same regions on the contralateral foot.…”

“…42,58,59,62 These shortterm acute temperature increases have been found to be correlated with the magnitude and locations of shear stress measured by research modalities (Figure 2). 58,60 Although some methods of measuring shear stress are promising, as discussed all methods should be considered within the context of their limitations. Many of the developed sensors lack adequate spatial resolution, are prone to structural, mechanical and thermal damage, and are sensitive to ambient temperature-related errors.…”

Excessive stress on plantar tissue over time is one of the leading causes of diabetic foot ulcers among people with diabetic peripheral neuropathy. Plantar tissue stress (PTS) is a concept that attempts to integrate several well-known mechanical factors into one measure, including plantar pressure, shear stress, daily weight-bearing activity, and time spent in prescribed offloading interventions (adherence). Despite international diabetic foot guidelines recommending the measure of each of these individual mechanical factors in people with neuropathy, only recently has technology enabled their combined measurement to determine PTS. In this article we review the concept of PTS, the mechanical factors involved, and the findings of pivotal articles reporting measures of PTS in people with neuropathy. We also discuss key existing gaps in this field, including the lack of standards to measure and report PTS, a lack of practical solutions to measure shear stress, and the lack of PTS thresholds that may indicate benefit or detriment to people with neuropathy. To address some of these gaps, we propose recommended clinical and research standards for measuring and reporting PTS in people with neuropathy. Last, we forecast future clinical, research, and technological advancements that may use PTS to highlight the importance of this critical concept in the prevention and management of diabetic foot ulcers.

“…Moreover, early hyperkeratosis studies identified frictional shear as a major factor in callus formations, which are well-documented risk factors. Shear also contributes to both acute and chronic plantar temperature increases ( 5 ), which makes the tissue susceptible to breakdown.…”
