Inclusion criteria
Inclusion criteria: All participants were evaluated during >3 consecutive radiological studies and via resting calcaneal stanindg position(RCSP) measurements. The following radiological param¬eters were screened to evaluate the alignment of both feet: anteroposterior talocalcaneal angle (APTCA), lateral talocalcaneal angle (LTTCA), lateral talometatarsal angle (LTTMA), and calcaneal pitch (CP). Flatfoot was defined as an angle of =4° at the valgus in either foot during RCSP and one of the following abnormal radiological findings: APTCA >30°, LTTCA >45°, LTTMA >4°, or CP <20°. Severe flatfoot was defined as an angle of =6° at the valgus during RCSP. We recruited only children aged 6–13 years of age with severe flatfoot.
Exclusion criteria
Exclusion criteria: (i) a fixed foot deformity, (ii) reported previous intervention (e.g., orthoses or surgery), (iii) congenital and developmental foot disease, and (iv) neuromuscular or central nervous system disease. Patients with a history of overuse or traumatic injury to the lower limb in the past 6 months, bony surgery to the lower limb, or systemic endocrine, neurogenic, or musculoskeletal disorders were excluded.
