Abstract To evaluate the changes in kinetic and temporospatial gait parameters following 1st metatarsalphalangeal joint (MTPJ) arthrodesis in a
population with severe hallux valgus deformity. A novel, fully integrated and wireless sensor insole (OpenGo, Moticon, München, Germany) was used for gait analysis. Hallux valgus is one of the most common foot pathologies resulting in changes of the plantar pressure distribution and gait patterns. In severe deformities this changes could lead to significant pain, disability and imbalance. This study is one of the first to analyse this population using specialised gait and motion detecting insoles.
