Objective
To study the relationship between plantar pressure and diabetic foot ulcer and the assessment the usefulness of plantar pressure measurement in diabetic patients.

Method
The total 94 diabetic patients were enrolled in this study. The plantar pressure was measured by using EMED-SF. And the nerve conduction studies, physical examination, and history taking were done. Patients were divided into 3 subgroups, Group A: without neuropathy and past ulcer history (n=31), Group B: with neuropathy and without past ulcer history (n=44), Group C: with neuropathy and past ulcer history (n=19).

Results
1) There were significant increase in the maximum peak pressure (MPP) and the pressure-time integral (PTI) values in the Group C as compared with the Group A and B (p＜0.05). 2) As compared among the groups for each areas, the MPP and the PTI significantly higher in group C for heel, medial fore-foot, and lateral fore-foot area than in another two groups (p＜0.05).

Conclusion
The high plantar pressure was significantly related with diabetic foot ulcer history. The plantar pressure measurement may be useful in diabetic patients as a predictive and management aids of diabetic foot ulcer.
