Abstract:
:Research by our group and others indicates that many amputations of the lower limb occur after foot ulceration in patients with diabetes. It has been proposed that diabetic foot ulcers are mainly caused by repetitive trauma in areas of high plantar pressure during walking. Recent technology permits in-shoe measurement of plantar pressure. We assessed the reliability of the F-Scan in-shoe system for measurement of plantar pressure (Tekscan Inc., Boston, MA) in 51 subjects from a cohort of 977 diabetic veterans enrolled in a prospective study of risk factors for foot ulceration and amputation (the Seattle Diabetic Foot Study). Subjects were tested twice, wearing their own shoes. We used the coefficient of variation (CV) and the intra-class correlation coefficient (ICC) to estimate the reliability of F-Scan measurements of pressure. Peak pressure over the metatarsal heads proved to have the best indices of reliability, with CVs of 0.150 and 0.155, and ICCs of 0.755 and 0.751. Coefficients of variation for the heel, whole foot, and hallux ranged from 0.148 to 0.240, with ICCs ranging from 0.493 to 0.832. By published standards, peak pressures over the metatarsal heads and right hallux met the criteria for excellent reliability. Our ICCs for high pressures under the foot, heel, metatarsal heads, and hallux, and for peak pressures under the heel and left hallux represented fair-to-good reliability. No F-Scan plantar measurements could be judged by these criteria as having poor reliability. This clinical study found that for elderly patients with diabetes who were wearing their own shoes and were tested on two different days with different insoles, the F-Scan insole system was generally reliable for measurements of high pressure and peak pressure.
