"If the ribs don't like to move during inhalation they are in exhalation,
And if they are restricted in exhalation then they are in inhalation,
Whichever rib stops moving first during inhalation is in exhalation dysfunction which means it is restricted in inhalation."
And for clarification
"The picture of exhalation restriction corresponds to the picture of inhallation"
It eventually made sense to me, but I had to laugh because it sounded like something I had read before:
"Be bent so as to become whole
Be crooked so as to become straight,
Be empty so as to become full,
Be worn so as to become new.
Posses little so as to acquire;"
The Doadejing
Who ever knew that studying ancient Chinese religious texts would help me in medical school!
