TY - JOUR T1 - Consistency of sternal percussion performed manually and with mechanical thumper JF - European Respiratory Journal JO - Eur Respir J SP - 1004 LP - 1008 DO - 10.1183/09031936.93.05081004 VL - 5 IS - 8 AU - AB Bohadana AU - SS Kraman Y1 - 1992/09/01 UR - http://erj.ersjournals.com/content/5/8/1004.abstract N2 - Auscultatory percussion is a technique that is potentially useful to study the acoustic behaviour of the chest. However, finger percussion, as used in this technique, has not been previously assessed for consistency. We calculated the intrasubject variability and short-term reproducibility of this technique in 10 healthy subjects. We examined several indices of the output sound of two series of sternal percussion manoeuvres performed one hour apart by the same examiner. The results were compared to those obtained during sternal percussion performed by a mechanical thumper. Consistency for both finger and thumper percussion varied from 4.8-20.6 (coefficients of variation) for various acoustic indices. For thumper percussion, the average results were not significantly different from those of finger percussion. We conclude that finger percussion of the sternum is sufficiently consistent to be used as a tool to investigate the acoustic behaviour of the chest. ER -
