Dropped feet or pes planus are among the most common foot deformities and one of the common musculoskeletal deformities in general. The development of dropped feet can be monitored, depending on the criteria and methodology, through three stages - pes valgus, pes planovalgus and pes planus. The frequency of a lowered foot arch is one case per thousand inhabitants. The etiology of flat feet can include congenital factors, in the case of congenitally flat feet, and acquired factors, in the case of acquired flat feet. External factors, for example, walking on hard flat surfaces, inadequate footwear, excessive body weight, etc., when combined with accelerated growth, consequently result in loosening of the arches of the feet. In adults, the abovementioned deformity most often occurs in professional occupations that involve long-term support on the feet, for example, doctors, hairdressers, restaurateurs, etc. The most commonly used diagnostic method for dropped feet is pedobarography. A dropped foot most often has the following features: pronation of the talus, valgus position of the heel, abduction of the anterior part of the foot and shortening of the Achilles tendon. The treatment of dropped feet is usually conservative and should be started as early as possible in order to achieve maximum results and avoid surgical treatment. The role of a physiotherapist is to carry out physiotherapy assessment procedures and create a plan for physiotherapy interventions. The most commonly used physiotherapy interventions for people with dropped feet are strengthening exercises, stretching exercises, coordination, balance and proprioception exercises, transcutaneous electrical nerve stimulation, electrostimulation and kinesio taping.
