  • Data are presented as mean±sd of means of each subject, unless otherwise stated. PEFR: peak expiratory flow rate; PIFR: peak inspiratory flow rate; VI: inspired volume; VE: expired volume; HuffHIGH: huff from high lung volumes. : data lost due to technical difficulties (data from different interventions lost in different subjects). p-value is significantly different from vibration. ***: p<0.001.
