Training inspiratory resistance in Duchenne dystrophy using adapted computer games

Abstract

Computer games were modified to encourage respiratory effort by two groups of patients with Duchenne muscular dystrophy. One group trained during the first six months of the study, the other during the second six months. Inspiratory effort was increased by their having to breathe through a mask to both start and continue the games. Pulmonary function tests were done at the beginning of the trial and six, 12 and 18 months later, when forced vital capacity, respiratory muscle endurance and strength were measured. Although there were some individual improvements, over-all the results were not statistically significant.
