Energy cost of walking and of wheelchair propulsion by children with myelodysplasia: comparison with normal children / Linda O. WILLIAMS in Developmental Medicine & Child Neurology, 25-5 (October 1983)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 25-5 (October 1983) . - p.617-624 Titre : Energy cost of walking and of wheelchair propulsion by children with myelodysplasia: comparison with normal children Type de document : Texte imprimé et/ou numérique Auteurs : Linda O. WILLIAMS, Auteur ; Lynn THOMAS, Auteur ; Joyce CAMPBELL, Auteur ; Amy D. ANDERSON, Auteur ; Earl FEIWELL, Auteur ; Joan M. WALKER, Auteur Année de publication : 1983 Article en page(s) : p.617-624 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The oxygen consumption of 15 myelodysplastic children during walking and propelling a wheelchair was studied. In comparison to normal children, they walked more slower and consumed more oxygen per meter, but had a similar rate of oxygen consumption. A swing-through gait pattern was 33 per cent more energy-efficient than a four-point gait pattern for these children. Wheelchair propulsion produced velocities and energy efficiencies similar to normal children walking. Oxygen consumption and velocity measurements were found to be significantly related to the clinical factors of level of lesion and strength of hip and knee extension. Regression lines and equations are presented to permit prediction of energy cost and efficiency from heart-rate data of myelodysplastic children.

Energy cost of walking in normal children and teenagers / Robert L. WATERS in Developmental Medicine & Child Neurology, 25-2 (April 1983)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 25-2 (April 1983) . - p.184-188 Titre : Energy cost of walking in normal children and teenagers Type de document : Texte imprimé et/ou numérique Auteurs : Robert L. WATERS, Auteur ; Helen J. HISLOP, Auteur ; Lynn THOMAS, Auteur ; Joyce CAMPBELL, Auteur Année de publication : 1983 Article en page(s) : p.184-188 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Oxygen consumption during free level walking was determined in 114 children and teenaged subjects between the ages of 6 and 19 years and compared with a group of 47 normal adults. Subjects were divided into two age groups: children (6-12 years) and adolescents (13-19 years). The mean rate of oxygen uptake for children was significantly greater, 15.3 ml/kg/min, than the value for teenaged subjects, 12.9 ml/kg/min. The oxygen cost to walk a unit distance (meter) was higher in children than adolescent subjects. The mean values averaged .22 ml/kg/min and .18 ml/kg/min respectively. The data on heart rate paralleled the findings on oxygen consumption. The mean heart rate for children, 114 beats per minute (bpm), was significantly higher than the mean values for adolescent subjects, 97 bpm.
