Kinesiological characteristics of ankle joint and rearfoot motion.

Kinesiological analysis of tarsal bones provides better understanding of foot disorders, especially in early childhood, when radiography is hindered by delayed ossification of foot bones. Children begin to walk in the age of 9-15 months, with rearfoot inversion only in initial contact phase, while inversion during terminal stance phase is delayed. Adult walking pattern is usually established at six years of age. Talocrural joint axis medial slope shifts during movements depending on the what part of talus comes in contact with maleolli. As a result, plantar flexion includes valgus, and dorsal flexion includes varus inclination. Subtalar joint axis highly varies among individuals: from 200-680 in sagittal and from 40-470 in frontal plane, with impact on coupled lower leg rotation movements around longitudinal axis. Midtarsal joint has two axes, and their position control the rigidity of forefoot and midfoot kinetic chain. Movement planes of tarsal bones strongly influence walking pattern as well as secure foot development.

Physical treatment of foot deformities in childhood.

During the period of development foot deformities can occur, not only during the growth and development, but also in the later age. The most frequent foot deformity is flatfoot, congenital club foot and hallux valgus. Prior to the decision on surgical treatment of the deformity, whenever possible the patient should be referred for physical therapy that may yield acceptable results in specific treatment phases. The basis of the treatment involves kinesitherapy, application of certain agents (thermotherapy, electrotherapy, ultrasound) and orthosis for maintaining corrections. If such therapy does not yield satisfactory results, the deformity is surgically corrected. After surgical correction, physical procedures can contribute to more rapid recovery and decrease possible complications (pain, edema, complex regional pain syndrome--Mb Sudec), which can follow the surgical correction of the deformity. In addition, the obligatory form of rehabilitation also involves kinesitherapy.
