A kinematic description of dynamic midfoot break in children using a multi-segment foot model

摘要: Midfoot break (MFB) is a foot deformity that occurs most commonly in children with cerebral palsy (CP), but may also affect other developmental disorders. Dynamic MFB develops because the muscles cross ankle joint are hypertonic, resulting breakdown and dysfunction of bones within foot. In turn, this creates excessive motion at midfoot. With inefficient lever arm, then unable to push off ground effectively, an inadequate painful gait pattern. Currently, there no standard quantitative method for detecting early stages MFB, which would allow intervention before further occurs. The first step developing objective tool diagnosis examine difference dynamic function between typical Therefore, main purpose study was compare differences feet (Controls) using multi-segment kinematic model. We found had significant decrease peak dorsiflexion compared Controls (1.3 ± 6.4° versus 8.6 3.4°) increase midfoot (15.2 4.9° 6.4 1.9°). This help clinicians track progression standardize treatment recommendations type deformity.
