Plantar pressure and shear stress during gait in people with diabetic neuropathy.
Aims: Diabetic foot ulcers are a leading cause of lower extremity amputations, significantly affecting the quality of life. Excessive plantar surface pressure and shear stress are key factors in ulcer development and aggravation. This study aimed to determine the association of these forces with the progression of diabetic peripheral neuropathy to help in foot-ulcer treatment and prevention.
Methods: Participants were categorized into four groups: individuals with no diabetes (NS), people with diabetes without peripheral neuropathy or foot-ulcer history (DM), those with diabetes with peripheral neuropathy but no foot-ulcer history (DPN), and people with diabetes with active or past foot ulcers (DFU). Plantar pressure and shear stress were measured during walking.
Results: The study included 47 participants. The DFU group demonstrated significantly higher pressure peak value and plantar pressure time integral value at the fifth metatarsal head compared to the DPN and DM groups. The DPN group exhibited significantly higher shear-stress time integral and shear stress time compared to the NS group.
Conclusions: In the DPN group, an increase in shear stress was observed. In the DFU group, an increase in plantar pressure and a tendency for an increase in shear stress were noted. Further research is needed to understand how these changes trigger the onset of foot ulcers.

期刊介绍：
Diabetology International, the official journal of the Japan Diabetes Society, publishes original research articles about experimental research and clinical studies in diabetes and related areas. The journal also presents editorials, reviews, commentaries, reports of expert committees, and case reports on any aspect of diabetes. Diabetology International welcomes submissions from researchers, clinicians, and health professionals throughout the world who are interested in research, treatment, and care of patients with diabetes. All manuscripts are peer-reviewed to assure that high-quality information in the field of diabetes is made available to readers. Manuscripts are reviewed with due respect for the author''s confidentiality. At the same time, reviewers also have rights to confidentiality, which are respected by the editors. The journal follows a single-blind review procedure, where the reviewers are aware of the names and affiliations of the authors, but the reviewer reports provided to authors are anonymous. Single-blind peer review is the traditional model of peer review that many reviewers are comfortable with, and it facilitates a dispassionate critique of a manuscript.
