Region-specific measurement strengths of the four stiffness assessment tools across plantar foot. A comparative overview of the region-specific performance characteristics of MyotonPRO, Durometer, IndentoPRO, and TCM based on multilayer phantom model analysis. The figure summarizes optimal assessment zones, heel (calcaneal), midfoot, and forefoot, for each tool, considering their mechanical sensitivity and correlation with SWE. The visualization supports an integrated approach to diabetic foot stiffness assessment by guiding tool selection based on anatomical region and measurement capability.
