    Abstract:
    Multilevel surgery for gait improvement was performed on twelve ambulatory children with diplegic type of cerebral palsy and dynamic equinus deformity. Dynamic equinus deformities were defined as those who had an equinus at initial contact during preoperative gait analysis, and where the equinus deformity was correctable passively during physical examination. Ankle function was evaluated by clinical examination and gait analysis before surgery, and at least 3 years after surgery. The ankle showed an increase in dorsal flexion at initial contact, at single stance and in swing. There was an increase in dorsal flexion at the beginning of push-off, without a decrease in the range of motion of the ankle during push-off. Ankle moments demonstrated significant improvement in the maximum flexor moment in the second half of single stance. There was a change from abnormal generation of the energy in mid-stance to the normal pattern of energy absorption. Positive work during push-off was significantly increased. Conservative management of dynamic equinus deformities combined with multilevel surgery to correct other deformities of the locomotion system resulted in significant improvements in ankle function during gait.
