The clinical impact of orthotic correction of lower limb rotational deformities in children with cerebral palsy: a randomized controlled trial

Abstract

Objective:

This study aimed to evaluate the effectiveness of a static ground reaction ankle foot orthosis and strapping system on improving gait parameters in children with spastic diplegic cerebral palsy.

Setting:

The current study was conducted at the physical therapy faculty of Cairo University, Egypt.

Subjects:

This study included 57 children of both sexes, aged 6 to 8 years.

Study design:

Three-armed randomized control trial.

Intervention:

Participants in all groups received a traditional neuro-developmental physical therapy program that included standing and gait training exercises. Children in group A performed the training program without any orthotic management, in group B with the TheraTogs™ strapping system, and in group C with the TheraTogs™ strapping system and static ground reaction ankle foot orthoses. Children underwent treatment for two hours daily, except on weekends, for twelve successive weeks.

Main measure:

Gait speed, cadence, stride length, and hip and knee flexion angles in the mid-stance phase were evaluated pre-and post-treatment using a three-dimensional motion analysis system (pre-reflex system).

Results:

Statistically significant differences were recorded among the three groups post-treatment in gait speed, cadences, and stride length. The P-values for these variable differences were 0.03, 0.011, and 0.001 respectively. Significant post-treatment differences were also recorded for bilateral hip-and knee-flexion angles. For all measured parameters, better significant results were registered for group C than for the other groups.

Conclusion:

Orthotic intervention composed of a static ground reaction ankle foot orthosis combined with the TheraTogs™ strapping system improves gait more than conventional treatment with or without TheraTogs™ in children with spastic diplegic cerebral palsy.
