title: Ankle and first metatarsophalangeal joint dorsiflexion in children with clubfoot.
abstract: It has been hypothesised that the stiffness of the plantar aponeurosis after clubfoot surgery affects push-off. Because the first metatarsophalangeal (MTP) joint motion relies on the plantar aponeurosis, it was important to determine whether there was a lack of first MTP joint motion in children with clubfoot that also affected push-off. By examining the motion of the first MTP joint using a motion analysis system and passive motion techniques, then correlating these with gait characteristics, the authors found that the first MTP joint was not affected in children with clubfoot. The authors found that a motion analysis system could be used to determine range of motion accurately.
