Adaptive seating and pulmonary function in adults with muscular disease

Abstract

Pulmonary infections, possibly due to poor pulmonary functions, are common in individuals with muscular dystrophy. In order to evaluate the relative effects of seating devices on pulmonary function the forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), and forced expiratory time (FET) in eight adults aged between 12 and 21 years with Duchenne Muscular Dystrophy was measured while seated in an adaptive and a nonadaptive seating device. The results showed a 28.0% increase in FVC, a 14.5% increase in FEV₁, and a 17.3% increase in FET in the adaptive seating system compared to the nonadaptive system. This result emphasizes the need for proper seating as an important way of maximising pulmonary function and minimizing pulmonary complications in this population.
