The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The purpose of this study is to compare the effect of Botox and casting to placebo and casting for reducing toe walking problems in children who are idiopathic toe walkers.
Condition or disease
Idiopathic Toe Walking
Drug: Botox injections
Patients who have been seen by one of the 5 paediatric orthopaedic surgeons at British Columbia's Children's Hospital and have been referred to the Shriner's gait lab for assessment of idiopathic toe walking will be eligible for the study.
The primary outcome will be based on gait analysis data - specifically whether post injection gait analyses show a reduction in the features that were used to determine the severity of the subjects' toe walking problem. [ Time Frame: Data not known ]
Secondary Outcome Measures :
Ankle range of motion (dorsiflexion and plantarflexion) [ Time Frame: collected at every visit ]
