Papel da press？o inspiratória máxima na avalia？？o da for？a muscular respiratória em asmáticos - Revis？o sistemática

asthma is a chronic illness of the airways that can reduce respiratory muscle strength due to the resulting hyperinflation or treatment with corticosteroids. one of the ways to evaluate this respiratory muscular weakness is the maximal inspiratory pressure (pimax). methods: a systematic review of the databases pubmed/medline, lilacs and scielo was carried through, using the key words: asthma, respiratory muscle and muscle strength. results: fifty were found and six articles that evaluated the pimax in asthmatics, from these, thirty were excluded, making a total of twenty six articles. final considerations: through the present revision we show the effectiveness of pimax in evaluating respiratory muscle strength in asthmatics. more studies are needed, however, fot better understanding of the asthmatic individual.
