Abstract:
Objective By using lung sound spectrum analysis, the clinical efficacy of asthma -relieving manipulation, which is a gentle massage therapy mainly on the acupoints, on acute exacerbation of children asthma was evaluated. Methods We collected the lung sound of 11 children with acute asthmatic attack before and after asthma-relieving manipulation, and then input to the computer for obtaining lung sound spectrum signal data. The sound intensity, average respiratory muscle strength ( RMS) power, total RMS power and the volume of every 25 Hz frequency spectrum were extracted for comparison. Results After asthma-relieving manipulation, the sound intensity, average RMS power, and total RMS power of the children with acute asthmatic attack were significantly lower than those before the manipulation (P<0.01). The results of lung sound spectrum analysis displayed that lung sound volume was significantly lower at frequency band 0~300 Hz after manipulation ( P<0.05 compared with that before the manipulation) . The difference of the lung sound volume was insignificant over frequency band 300 Hz before and after treatment ( P>0.05). Conclusion Lung sound spectrum analysis can be applied to monitor lung function of asthmatic children objectively and quantitatively, and it is a new sensitive method for clinical detection. Asthma-relieving manipulation shows certain effect on acute exacerbation of children asthma.
