Gait analysis in hallux valgus

Abstract

The solar pressure zones were analyzed in the feet of 66 patients suffering from hallux valgus, together with 60 normal subjects. The EMED Gait Analysis System was used. In the hallux valgus group, the maximum pressure was found to be increased significantly in the small toe region and more proximally situated, close to the metatarsophalangeal joint. In the normal subjects, the maximum pressure was increased significantly in the first, second, third, and fourth metatarsal and heel regions. In general, the hallux valgus group had smaller contact areas compared to the control group. The increased pressure in the small toe region, together with the smaller contact areas manifested by the hallux valgus group, were interpreted in this work as being the possible causes of the metatarsalgia seen in patients with the deformity.
