Abstract
PURPOSE: We determined the effect of changes in abduction orthosis for clubfoot (bar width, dorsiflexion and abduction) on ankle dorsiflexion and foot abduction. METHODS: The study included 31 children with clubfoot. An adjustable Steenbeek foot abduction orthosis permitting variations of bar width [distance between anterior superior iliac spines, shoulders and 'standard'], dorsiflexion (0, 15 and 30°) and abduction (30, 45 and 70°) was used for measurements. Ankle dorsiflexion and foot abduction were measured with and without orthosis and compared using repeated measures analysis of variance (ANOVA). RESULTS: Foot abduction was same as orthotic abduction in all configurations. A better ankle dorsiflexion was found with a shorter bar width, larger orthotic dorsiflexion and abduction. Contrarily, the arc increased with a wider bar. A 30° inbuilt orthotic dorsiflexion and 70° abduction produced better foot dynamics. CONCLUSIONS: A foot abduction orthosis with modifications of shorter bar length, 30° dorsiflexion and 70° abduction may offer better soft tissue stretch and foot motion in clubfoot.
