Gait & posture, 2002•ElsevierNine subjects (12 sides) with cerebral palsy who walked in equnius were evaluated prior to
and 1 year after surgical tendo Achilles lengthening. Gastrocnemius and soleus length [Gait
Posture, 6 (1997) 9] and plantarflexor force [Gait Posture, 6 (1997) 9; J Biomech, 23 (1990)
495] were calculated. The length of the gastrocnemius and soleus increased significantly
(P< 0.01) following the intervention. Force output of the triceps surae during push-off
increased significantly (13.95 N/kg body weight (BW) preop to 30.31 N/kg BW postop; P< …

Assessment of the force–length capacity of the triceps surae in candidates for tendo Achilles lengthenings may identify individuals at risk of residual weakness and iatrogenic crouch.
