Prescribe rigid body kinematics postview1/10/2024 This has been shown in healthy adults, healthy elderly individuals, and patients with knee osteoarthritis. It seems that the lever arm of the ground reaction force (GRF) is directed to the joint center. In healthy adults, these changes are most likely due to a shift of the center of pressure to the direction of FOs posting. These authors were able to show altered frontal plane moments, particularly at the ankle and knee joints, when walking or running with medially posted FOs. More research was conducted in healthy adults and children with flexible FF. These studies revealed small reductions in peak rear foot eversion (up to 1–3 degrees) in the FO condition. Previous research examined the effects of FO treatment versus a sham condition (i.e., regular insoles) on walking and running kinematics in healthy adults and adults with FF. However, this potential effect was not confirmed in the literature in both, healthy adults and adults with FF. The rationale behind the application of FOs is that they are supposed to realign the lower limb through changes in lower extremity kinematics. We used arch support FOs in this study that were manufactured with a negative cast technique in subtalar joint neutral position. However, the biomechanical mechanisms underlying the therapeutic effect of FOs in children with flexible FF is still unclear. Moreover, it has been reported that FOs are effective means to treat a variety of painful feet conditions including the high or low arched foot, rheumatoid arthritis, and plantar fasciitis. There is evidence from Australian Podiatrists indicating that during the last decade, 91% prescribed either functional (individualized) or prefabricated orthotics to individuals (adults and children) with FF. In a recent website audit, it was found that 47% of websites from Canadian Chiropractors advertise orthotics for sale. A variety of intervention programs are used to treat such problems, with foot orthoses (FOs) being a popular means. It has previously been shown that children with flexible FF compared with aged-matched healthy peers are more likely to suffer from pain or discomfort at the knee, hip, or trunk. Of those children with FF, 10% receive treatment for the prevention of secondary deformity during adulthood.
