  • Title: Physical work capacity in adolescent patients with mild idiopathic scoliosis.
    Author: DiRocco PJ, Breed AL, Carlin JI, Reddan WG.
    Journal: Arch Phys Med Rehabil; 1983 Oct; 64(10):476-8. PubMed ID: 6625882.
    Abstract:
    The purpose of this study was to investigate the physical work capacity of adolescent patients with mild idiopathic scoliosis (less than 60 degrees). Fourteen subjects, who were being treated with a Milwaukee brace, were given a progressive exercise stress test. Ventilatory volume, frequency of breathing, end-tidal PCO2, heart rate, and blood pressure were continuously monitored and oxygen consumption (VO2) was computed for each work load. Results indicated that the majority of subjects were 1 to 4 standard deviations above the mean for nonhandicapped peers in expired ventilation, and all of the subjects were 2 standard deviations or more below the mean for their nonhandicapped peers in VO2max. The low work capacity was similar to that reported in individuals with much larger curves. Reduced work capacity was not apparently limited by maximal attainable ventilation or ventilatory pattern (frequency). Reduced aerobic fitness cannot be ruled out.
