This study demonstrates that when
percussion is applied by
physiotherapists to a patient model
with normal lung function, a wide
range in the rate and force of
application is present. Some previous
studiesinvolving percussion have
~applied the technique atrates which
are not representative ofthose found in
the present study. The findings
indicate that clinically, and in further
studies, the force·ofpercussion should
not be predicted from gender, body
weight, BMI or frequency of usage of
the ·technique. The rate of percussion
should not be used as an indicator of
force. The foreeaf percussion may be
related to the technique used. Most
physiotherapists demonstrate a hand
dominance.
