- Abstract
Next, for ITWs the generic passive ankle moment-angle curves for the gastrocnemii and soleus were shifted by 20° into plantarflexion (Figure 1), because the maximum passive dorsiflexion range in ITWs was ~20° smaller than for TD children (Harkness-Armstrong et al., [4]).

([3]) analysed gastrocnemius fibre operating ranges during gait in children diagnosed as idiopathic toe walkers (ITWs) and in typically developing (TD) children. To do so, we created a pathology-specific contracture model for ITWs by implementing a musculotendon contracture in a generic musculoskeletal model (Delp et al., [2]) that was simplified to include only a lumped gastrocnemius and a soleus muscle as plantarflexors (Veerkamp et al., [10]).
