  • energy consumption in children with myelomeningocele a comparison between reciprocating gait Orthosis and hip knee ankle foot Orthosis ambulators
    Developmental Medicine & Child Neurology, 2008
    Co-Authors: T J Cuddeford, Michael D Aiona, Renee P Freeling, Susan Thomas, Henry Sirolli, Joanne Elliott, Mark Magnusson
    Abstract:

    : This study compared the differences in energy efficiency (energy cost) in children with myelomeningocele ambulating with either reciprocating gait orthoses (RGOs) or Hip-Knee-Ankle-Foot orthoses (HKAFOs). There were 15 children who ambulated with RGOs and 11 children braced and ambulating in HKAFOs. Velocity was measured in m/s, energy consumption was measured in mL/kg/min, and energy cost (energy consumption/velocity) was measured in mL/kg/m. Children in HKAFOs had a significantly higher energy consumption rate than children in RGOs. However, children who swing through in a HKAFO have a significantly faster velocity than children who ambulate with the RGO using a reciprocating pattern. The increased energy cost in the RGO group is influenced by their slower velocity, just as the decreased energy cost in the HKAFO group is influenced by their increased velocity. Therefore it appears that children in HKAFOs are more energy efficient than children in RGOs.

  • longitudinal assessment of oxygen cost and velocity in children with myelomeningocele comparison of the hip knee ankle foot Orthosis and the reciprocating gait Orthosis
    Journal of Pediatric Orthopaedics, 2001
    Co-Authors: Susan Sienko Thomas, Cathleen E Buckon, Jeanne B Melchionni, Mark Magnusson, Michael D Aiona
    Abstract:

    : Oxygen consumption and cost and velocity were evaluated over time in 23 children with myelomeningocele to determine whether differences exist when children walk with Hip-Knee-Ankle-Foot orthoses (HKAFOs) versus reciprocating gait orthoses (RGOs). Children using HKAFOs had similar oxygen cost as children using RGOs while achieving a faster velocity. Children walking with HKAFOs into adolescence had a faster velocity and lower oxygen cost than children who discontinued use of their HKAFOs. No significant differences in velocity or oxygen cost were found between children who continued to walk with RGOs and those who discontinued use of their RGOs. Upright ambulation may progress from ambulation with an RGO, when the child's upper extremity strength to mass ratio is low, to an HKAFO when upper extremity strength improves and velocity or keeping up with peers is of concern. Wheelchair mobility should be offered when speed and an energy-efficient method of community mobility are desired.
