Spirometric measurements and physical efficiency in children and adolescents with hearing and visual impairments.
The objective of the study was to investigate whether a sensory impairment has an effect on functional capabilities of the respiratory system and whether possible deviations from reference ranges of selected parameters might indicate a decrease of physical efficiency. Vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF), forced expiratory flow of 25-75% (FEF25-75), maximum voluntary volume (MVV), and maximum oxygen uptake VO2 max were measured in 86 deaf and 102 blind children and adolescents, and in a matched group of hearing controls. We found a significant influence of deafness on PEF (P<0.01), FEF25-75 (P<0.05), and MVV (P<0.05). As compared with the control subjects, mean VC was significantly lower in blind adolescents (P<0.05). Our results seem to suggest that both sensory defects during childhood and adolescence affect functional capabilities of the respiratory system.
