  • 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: inspiratory volume; VE: expiratory volume; PEP: peak expiratory pressure; TLCrelax: total lung capacity positive expiration. : data lost due to technical difficulties (data from different interventions lost in different subjects); +: data only collected from stated number of subjects. p-values are significantly different from vibration. ***: p<0.001; #: p = 0.002.
