Effect of Intermittent Serial Casting on Equinus Ankle Deformity in Children with Hemiplegic Cerebral Palsy

Abstract
Background: Equinus is the most common problem in ambulatory children with spastic hemiplegic cerebral palsy, which results in an unstable and inefficient gait pattern. Without proper management at an early stage, it can lead to permanent foot deformities.
Aim of Study: The aim of this study was to evaluate the effect of serial casting on ankle range of motion, tone of the calf muscle and ankle kinematics during gait in children with spastic hemiplegic cerebral palsy.
Material and Methods: Twenty-five spastic hemiplegic cerebral palsy children of both sexes (15 boys and 10 girls) participated in this study. Patients were selected at level I according to Gross Motor Function Classification System and the degree of spasticity ranged from 2 to 3 according to Modified Ashworth Scale with true equinus, with their mean age were 4.8±0.8 years. They were randomly assigned to two groups. The first group, 12 children, Group (A) who received a selected physical therapy program once a day/3 times a week for three successive weeks; while the second group, 13 children, Group (B) who received three consecutive casts for five days each and removed in the last two days in each week to conduct the same selected physical therapy program which conducted for the Group (A). Ankle range of motion was assessed by electronic goniometer, calf muscle spasticity was assessed by modified ashworth scale and ankle kinematics during gait was assessed by observational gait scale.
Results: The results of the present study revealed that Group (B) showed statistically significant improvement in ankle range of motion, tone of calf muscle and ankle kinematics during gait (p=0.0001 for all) than those of the Group (A).
Conclusion: Serial casting of equinus ankle deformity could improve ankle range of motion, tone of calf muscle and ankle kinematics during gait in children with spastic hemiplegic cerebral palsy.
