Flat feet is one of the most common deformities of the foot, which is neglected in many cases, although it can cause various painful conditions. The normal anatomical position of the foot arch is disturbed and needs to be corrected. In young children it is very easy to mistake fatty deposits on the soles with deformities, so it is important to determine whether it is really a flat feet. There are various methods and procedures which are used to assess the position of the feet and to determine the distortion: mainly plantography or pedobarography. Any discrepancy must be noted to help recommend therapy. Prior to the physiotherapy intervention, a detailed assessment should be made which includes subjective and objective examination, inspection and palpation of the feet, and gait assessment to analyze posture and gait pattern. This is followed by measurements that include measurements of range of motion in the joints and a manual muscle test. After the assessment, it is necessary to perform exercises of strengthening, stretching and coordination and balance. Strengthening exercises serve to strengthen muscles and ligaments and are characterized by overcoming the resistance of your own body or external load. Stretching exercises help establish, maintain and improve the mobility of joints and shortened muscles. Coordination and balance exercises participate in the realization of the movement of each structure. Kinesio taping which reduces pain, improves circulation and stabilizes joints and improves muscle function is also used. As deformity of flat feet is becoming more common in children, preventive measures are used in early childhood such as orthopedic shoes or insoles.
