Comparison of lung functions between the subjects who received mechanical insufflation-exsufflation (MI-E) therapy and the subjects who received intermittent positive pressure breathing (IPPB) therapy. a Forced vital capacity (FVC) of predictive value were significantly higher in subjects who received MI-E therapy (open bar), compared to the subjects who received IPPB therapy (black bar) (* indicates p < 0.05); b Forced expiratory volume in one second (FEV₁) of predictive value were significantly higher in subjects who received MI-E therapy (open bar), compared to the subjects who received IPPB therapy (black bar) (* indicates p < 0.05); c Peak expiratory flow rate (PEF) of predictive value were no significant difference between both groups; d The difference between pre-operative and post-operative values of FVC, FEV₁, PEF were significantly higher in subjects who received MI-E therapy (open bar), compared to the subjects who received IPPB therapy (black bar) (* indicates p < 0.05); (data expressed as mean ± SEM)
