OBJECTIVITY IN MUSCLE TESTING
Handheld devices measure the amount of force exerted
manually by the examiner. This concern thought even so with regards to
making love modifications with Mulroy et the state of alabama.
It is evident that the variety of devices used and the
many variables involved preclude the establishment of
norms for muscle grading.
