Abstract
Aims: The aim of this study is to determine the forefoot pressure distribution in normal subjects and in patients with metatarsalgia and to present an application of the electronic pedobarography in the design of orthoses. Methods: A control group of 358 normal subjects and a pathological group of 100 patients with metatarsalgia were studied with a wireless portable system for plantar pressure dynamic measurement. Each patient of the pathological group had their metatarsal head loads reequil-ibrated according to the loads obtained in the control group, by means of a set of orthopaedic sights located below the metatarsal heads which supported the lowest load, increasing its pressure support and lightening thus the overloaded metatarsal heads. The aim was to obtain a balance between the þve metatarsal heads similar to the control group. This balance was assessed with the electronic portable system. Results: The pathological group had a signiþcantly higher pressure under the third metatarsal head. The third metatarsal head pressure was significantly decreased, and the þrst, fourth and þfth metatarsal head pressures were signiþcantly increased by means of orthopaedics sights. Conclusions: The forefoot pressure distribution in patients with metatarsalgia differs from normal subjects. Redistribution of metatarsal head loads assessed by means of a electronic system can contribute to the design of orthoses to treat metatarsalgia.
