The effects of orthoses, footwear, and walking aids on the walking ability of children and adolescents with spina bifida: A systematic review using International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY) as a reference framework.

BACKGROUND: To date no review has been published that analyzes the efficacy of assistive devices on the walking ability of ambulant children and adolescents with spina bifida and, differentiates between the effects of treatment on gait parameters, walking capacity, and walking performance.

OBJECTIVES: To review the literature for evidence of the efficacy of orthotic management, footwear, and walking aids on gait and walking outcomes in ambulant children and adolescents with spina bifida.

STUDY DESIGN: Systematic literature review.

METHODS: A systematic literature search was performed to identify studies that evaluated the effect of any type of lower limb orthoses, orthopedic footwear, or walking aids in ambulant children (≤18 years old) with spina bifida. Outcome measures and treatment results for gait parameters, walking capacity, and walking performance were identified using International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY) as the reference framework.

RESULTS: Six case-crossover studies met the criteria and were included in this systematic review. Four studies provided indications of the efficacy of the ankle-foot orthosis in improving a number of kinematic and kinetic properties of gait, stride characteristics, and the oxygen cost of walking. Two studies indicated that walking with forearm crutches may have a favorable effect on gait. The evidence level of these studies was low, and none of the studies assessed the efficacy of the intervention on walking capacity and walking performance.

CONCLUSIONS: Some data support the efficacy of using ankle-foot orthosis and crutches for gait and walking outcomes at the body functions and structures level of the ICF-CY. Potential benefits at the activities and participation level have not been investigated.

CLINICAL RELEVANCE: This is the first evidence-based systematic review of the efficacy of assistive devices for gait and walking outcomes for children with spina bifida. The ICF-CY is used as a reference framework to differentiate the effects of treatment on gait parameters, walking capacity, and walking performance.
