Clinical, electrodiagnostic and pedobarographic assessments of leprotic patients with trans-tibial amputation

The aim of present study was to investigate clinical, electrodiagnostic and pedobarographic findings of non-amputee limb in chronic leprotic patients with unilateral trans-tibial amputation to determine neuropathy and plantar foot pressure in non-amputee limb. During the present prospective cross-sectional study, 10 chronic leprotic patients with unilateral trans-tibial amputation were evaluated. The study was conducted in Tabriz Bababaghi and Imam Reza Hospitals at summer of 2008. Sensory nerve conduction (SNAP) and Compound Motor Action Potentials (CMAP) studies were performed in association with pedobarographic assessment. No reliable response was detected from tested sensory and motor nerves, except a very low amplitude finding in deep preoneal nerve of one patient. In comparing with healthy group, static total plantar area, dynamic total plantar area, static rarefoot peak pressure and dynamic rarefoot peak pressure were lower in leprotic patients (p = 0.047, p = 0.004, p = 0.029 and p<0.001), while static forefoot peak pressure and dynamic forefoot peak pressure were higher in these patients (p = 0.011 and p = 0.031). All of leprotic patients with unilateral trans-tibial amputation suffered from severe neuropathy. Also, these patients have high plantar pressure under the forefoot. Collectively, severe neuropathy and abnormal plantar foot pressure expose in non-amputee foot expose leprotic patients to the higher risk of secondary amputation. é 2009 Asian Network for Scientific Information.
