Similarly, this study revealed that percussion
significantly decreased the systolic blood pressure (SBP)
when subjects were in prone lying with foot of bed raised
45cm.. This result contradicted the findings of White and
Mawdsley (1983) and Arigbabuwo and Adedoyin (2002)
who reported that the addition of percussion to level side
lying and head down lying did not significantly affect the
CV parameters. However, this study supported the findings
of Barre and Abass (1978) who reported that pulmonary
physical therapy that included percussion had effect on
the cardiovascular system when administered to patients
within 24 hrs although in a mitral valve surgery. Since
some cardiovascular and cardiorespiratory parameters
most especially systolic blood pressure and respiratory
rate showed significant changes when participants change
from sitting to prone lying, foot of bed raised 45cm, and
right side lying positions.
