"Because so many physicians are uninformed about ME, some at long COVID clinics prescribe therapies that have been proven to be harmful to patients who experience post-exertional malaise (PEM). Graded exercise therapy (GET)—a controversial form of physical therapy for ME and long COVID which slowly increases exercise over time— worsens patients’ symptoms who experience PEM. 'Graded exercise therapy implies that you can exercise yourself into fitness and resolve the illness,' Bateman says. 'When in reality, that’s not the case.'"
