Values are means (SE) data for dependent variables according to task and cough number. CPD, compression phase duration; PEFRT, peak expiratory flow rise time; PEFR, peak expiratory flow rate; CVA, cough volume acceleration; PPPIA, post-peak plateau integrated area; PPPD, post-peak plateau duration; Max RA EMG, maximum EMG from the rectus abdominus; RMS RA EMG, root mean square EMG from the rectus abdominus; Max IC8 EMG, maximum EMG from the eighth intercostal space; RMS IC8 EMG, root mean square EMG from the eighth intercostal space; AU, arbitrary units.
