If the examiner believes that there is an organic basis (a true clinical condition) for the restricted range of motion, then:

ANSWER: b. the examiner should perform three measurements of range of motion and use the greatest range measured for grade modifier determination

RATIONALE: Range of motion of the joints in the lower extremity may be assessed as a method of determining a physical examination grade modifier, if it is clear to the examiner that there is a clinical reason...
