Predictive value of forefoot plantar pressure to predict reulceration in patients at high risk García Madrid, Marta García Álvarez, Yolanda Sanz Corbalán, Irene Álvaro Afonso, Francisco Javier López Moral, Mateo Lázaro Martínez, José Luis Aims: To analyze a plantar pressure cut-off point for diabetic foot reulceration beneath the metatarsal heads in patients with previous forefoot amputation. Methods: A one-year prospective study was conducted in a total of 105 patients at high risk for foot ulceration. Peak plantar pressure (PPP) and pressure-time integral (PTI) in the entire foot, the forefoot region, and each metatarsal head separately were registered. ROC curves were used to select the optimal diagnostic pressure cut-off points. Patients were follow-up monthly or until the development of an ulcer event. Results: A total of 52 (49.5%) patients developed a reulceration. Using ROC analyses for PPP in the full-foot and in the forefoot, did not predict reulceration beneath the metatarsal heads. Analyzing separately each metatarsal head all patients with values greater than or equal to 20.8 N/cm2 at the 1st, 18.62 N/cm2 for the 2nd, 18.85 at the 3rd, 17.88 at the 4th, and 12.2 at the 5th metatarsal heads will suffer a reulceration despite the use of orthopedic treatment with optimum values of sensitivity (from 100 to 87.5) and specificity (from 83.2 to 62.8). Conclusion: Barefoot pressures beneath the metatarsal heads should be analyzed separately to predict the region at risk of reulceration. 2023-06-22T10:54:43Z 2023-06-22T10:54:43Z 2023-06-22T10:54:43Z 2022-06-30 journal article https://hdl.handle.net/20.500.14352/71876 0168-8227 10.1016/j.diabres.2022.109976 eng https://creativecommons.org/licenses/by-nc-nd/3.0/es/ open access Atribución-NoComercial-SinDerivadas 3.0 España Elsevier
