Plantar loading reflects ulceration risks of diabetic foot with toe deformation.

Lu YC, Mei QC, Gu YD - Biomed Res Int (2015)

Bottom Line: Peak pressure was significantly higher in the patients with toe deformity in rearfoot, central forefoot, and great toe regions compared with the control group.Diabetic patients with fifth-toe deformity could have plantar contact area reduction in the other toes part and increased loading to the great toe part.The result showed that fifth-toe deformity was associated with potential ulceration risk especially in hallux region.

ABSTRACT
Diabetes has been one of the most common chronic diseases all over the world. The purpose of this study was to quantitatively assess the foot loading characteristics of diabetic patients with fifth-toe deformity through a comparative analysis with diabetic patients with healthy and normal feet. Six neuropathic diabetic female subjects with the fifth-toe deformation and six age-matched neuropathic diabetic controls without any feet deformities participated in the walking test. Dynamic barefoot plantar pressure was measured with Novel EMED force plate. Peak pressure and pressure-time integral for all 7 foot regions (rearfoot, midfoot, lateral forefoot, central forefoot, medial forefoot, great toe, and other toes) were collected. Peak pressure was significantly higher in the patients with toe deformity in rearfoot, central forefoot, and great toe regions compared with the control group. Meanwhile, loading sustaining period extended longer in great toe region of deformed group than in that of the control group, and the center of pressure was nearly in the big toe region during toe offstage. Diabetic patients with fifth-toe deformity could have plantar contact area reduction in the other toes part and increased loading to the great toe part. The result showed that fifth-toe deformity was associated with potential ulceration risk especially in hallux region.

fig4: Pressure-time integral comparison between the fifth-toe deformed group and control group (∗significant difference, P < 0.05).

Mentions: Comparing the pressure-time integrals, the lateral forefoot (LFF), central forefoot (CFF), medial forefoot (MFF), great toe (GT), and the other toes (OT) parts showed significant difference. But as to the pressure-time integral in the GT and CFF regions, deformed group were significantly larger than those of the control group (Figure 4). The result compared with peak pressure features showed different patterns, mainly in the RF, LFF, and MFF areas. For RF region, the pressure-time integral did not show significant difference, but in the LFF and MMF regions, no significance was illustrated in peak pressure value.
