NCT01590693

Brief Summary

The purpose of this study is to determine whether botulinum toxin A (BTX) adds a favourable effect to treatment of idiopathic toe-walking with below knee walking casts. The specific hypothesis to be tested is that a combination of BTX and casting is more effective than casting treatment alone in reducing toe-walking in 5-15 year old children. Evaluation methods include 3-D gait analysis, parents' perception of toe-walking frequency, passive joint range of motion measurements, and strength of ankle dorsal extension.

Study Arms (2)

Group 2

EXPERIMENTAL

Children treated with four weeks of below knee walking casts and botulinum toxin A injections

Drug: Botulinum toxin A

Group 1

ACTIVE COMPARATOR

Children treated with four weeks of below knee walking casts.

Drug: Botulinum toxin A

Interventions

The children in Group 2 underwent bilateral treatment with a total of 12 units/kg bodyweight Botox® (Allergan, California, USA). Four injection sites in each calf - two in the proximal third of the lateral and medial gastrocnemius bellies and two distally in the gastrocnemius-soleus complex - were administered. All injections were performed with electromyogram amplifier guidance to ensure intramuscular position. Children in both groups were treated with four weeks of below knee walking casts. Children in group 2 received the casts 1-2 weeks after botulinum toxin A treatment.
