dc.description.abstractPhysiotherapists often use adventitious lung sounds(ALS), i.e., wheeze(Wh) and crackle(Cr), to monitor respiratory techniques in acute obstructive(AO) and restrictive(AR) respiratory patients. ALS are responsive to bronchodilators however, evidence regarding its usefulness in respiratory physiotherapy(RP) is scarce. This study aimed to assess the responsiveness of ALS to one session of RP applied in acute obstructive and restrictive respiratory patients. RP included breathing retraining and airway clearance techniques. Sound recordings were acquired with a digital stethoscope pre/post intervention, following the CORSA short-term acquisition guidelines. Computerised analysis was used to characterise Wh(occupation rate and duration) and Cr parameters(number and two cycle duration-2CD) per breathing cycle(BC). Comparisons were explored with Paired-Samples t-Tests(PASW 18.0). Thirty outpatients(14 males, 55.2±17.8y), diagnosed with AO(exacerbation of COPD, acute bronquitis & asthma;n=18) and AR diseases(pneumonia; n=12) were recruited. A significant decrease for Wh occupation rate(t=4.19, p=0.03) and duration(t=2.35, p=0.04) per BC, in the trachea, was found for AR patients. In all chest locations, the number of Cr per BC, presented a significant increase(t=-2.71, p=0.01) for AO and decrease(t=2.05, p=0.05) for AR patients. No significant differences were found for the 2CD. Both Wh and Cr changed significantly in response to RP. Wh and Cr decrease in AR diseases may be indicative of more airways opened after treatment. Cr increase in AO diseases, suggest movement of secretions to more central airways, allowing more air to pass and leading airways to suddenly open. Further research is recommended.pt_PT
