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.
