Results of the Use of Navicular Support Foot Orthoses in Children with Flatfeet
Various foot orthoses have been studied for their ability to alleviate the symptoms of flatfoot. While many interventions feature medial longitudinal arch support, this study aimed to compare resting calcaneal standing position, talocalcaneal angle, talo-metatarsal angle, and navicular height before and after treatment with navicular support in children with flatfeet. In total, 10 participants (6 males and 4 females; mean age 10.8 ± 1.61 years) wore navicular orthotic support for more than 8 hours a day throughout the 12-month study period. X-ray and physical measurements were carried out before the intervention (baseline) and after 6- and 12-months of treatment. All measurements were performed without orthotics. Analysis showed that the resting calcaneal standing position and navicular height increased, while the talocalcaneal and talo-metatarsal angles decreased, when comparing data at baseline to 6- and 12-months of treatment. In summary, our research findings show that orthotics with navicular support improve the symptoms associated with flatfeet in children when worn for more than 8 hours per day for at least 6-months.
