Values for pre- and post-treatment are presented as mean (SD)
Pre pre-treatment; Post post-treatment; ic initial contact, df ankle dorsiflexion, pf ankle plantarflexion w weeks; m months
aReference values from the laboratory pediatric control database of 23 children (aged 5–14 years) with typical motor development
bValues are in degrees, where positive values indicate dorsiflexion and negative values indicate plantarflexion
cValues in percent of gait cycle
