Background: The aim of this study was to identify mechanical risk factors of diabetic foot ulcers and presenting biomechanical solving to prevent diabetic foot ulcers. Methods: Related articles from validate electronic and indexed sources from 1990 to 2014 were studied. In summation, 140 articles from electronic databases and journals, Elsevier, Pumped, Up to date, Google scholar, Cochrane library, were used. Results: Studies identified peak plantar pressure, shear force and time pressure and force integral as causes of diabetic foot ulcers. Intervention Factors such as peripheral neuropathy, skeletal abnormalities, muscle weakness, muscles cocontraction, hypomobility and reduced static and dynamic balance have been identified as aggrevating factors for mechanical risk of diabetic foot ulcers. Conclusion: Shear force, peak plantar pressure and time pressure integral are the most important mechanical risk factors for diabetic’s foot ulcers. Thus, good shoes and insoles can act as a filter and correct variables which effect ulcers such as force, pressure and time pressure integral.
