Note that I said "a central problem", not "the central problem". Not all ME/CFS patients put OI high up on the list, though some, including myself, do. In these patients it was called "refractory", which is enough to merit special attention.Why do you assume that their central problem was OI? According to the paper, they were clearly diagnosed with ME/CFS.
Having read the Fukuda criteria for CFS, I don't think these mean much. In particular, they don't mention orthostatic intolerance at all, and PEM is not required:
It is even possible that CSS would be considered an exclusionary condition.A thorough medical history, physical examination, mental status examination, and laboratory tests (diagram) are recommended to identify underlying or contributing conditions that require treatment. Diagnosis or classification cannot be made without such an evaluation. Clinically evaluated, unexplained chronic fatigue cases can be classified as CFS if the patient meets both of the following criteria:
These symptoms persisted or recurred during 6 or more consecutive months of illness and they cannot have first appeared before the fatigue.
- The individual has severe chronic fatigue for 6 or more consecutive months that is not due to ongoing exertion or other medical conditions associated with fatigue (these other conditions need to be ruled out by a doctor after diagnostic tests have been conducted)
- The fatigue significantly interferes with daily activities and work
- The individual concurrently has four or more of the following symptoms:
- post-exertion malaise lasting more than 24 hours
- unrefreshing sleep
- significant impairment of short-term memory or concentration
- muscle pain
- pain in the joints without swelling or redness
- headaches of a new type, pattern, or severity
- tender lymph nodes in the neck or armpit
- a sore throat that is frequent or recurring
