Comment: The Orthostatic Grading Scale CRF is modified from the Orthostatic Grading Scale (Schrezenmaier et. al., 2005), which asks about "orthostatic symptoms". Because respondents with or without ME/CFS might not be familiar with what "orthostatic" symptoms are, the questionnaire has been expanded to ask about four common orthostatic symptoms (fatigue, lightheadedness, problems thinking and concentrating, and blurry vision).

Comment: The Orthostatic Grading Scale CRF is modified from the Orthostatic Grading Scale (Schrezenmaier et. al., 2005), which asks about "orthostatic symptoms". Because respondents with or without ME/CFS might not be familiar with what "orthostatic" symptoms are, the questionnaire has been expanded to ask about four common orthostatic symptoms (fatigue, lightheadedness, problems thinking and concentrating, and blurry vision).
