Energy Expenditure in Patients With Low-, Mid-, or High-Thoracic Paraplegia Using Scott-Craig Knee-Ankle-Foot Orthoses

Abstract

Renewed interest in ambulation in patients with paraplegia prompted us to measure the energy expenditure (kcal/kg per min) during standing and ambulating with the Scott-Craig orthosis in nine patients who had low-, mid-, or high-thoracic paraplegia. Energy expenditure during standing and during ambulation with a walker was similar for patients with all levels of paraplegia. In patients with high-thoracic paraplegia, energy efficiency was significantly less (P less than 0.05) than that for patients with mid- or low-thoracic paraplegia, whose efficiency levels were similar. In patients with low-thoracic paraplegia, the only patients who could perform swing-through gait patterns, energy efficiency was increased because of increased velocity. Our data do not support the concept of denying, on the basis of the level of the lesion alone, young, otherwise healthy, well-motivated patients with thoracic paraplegia the opportunity of using Scott-Craig orthoses to supplement wheelchair mobility and activities of daily living.
