CONSISTENCY STUDY OF STERNUM MANUBRIUM PERCUSSION USING PHASE SPACE

摘要

This paper presents the consistency of percussion in a clinical environment. By measuring the input to the system and then obtaining the response to such a stimulus we are then able to model the system as a transfer function, assuming that non-linearity is not significant. However in order to eliminate the need to measure the input to the system we are required to determine besides general consistency the input characteristics across different medical personnel. This work will show that the input is consistent, providing we have experienced percussors. We present Phase Space portraits (measured signal against it's first derivative) since graphical representation is substantially easier to cross compare than blind statistics which alone generally do not have an intuitive meaning.
