Researchers tested a German-language questionnaire designed to measure post-exertional malaise (PEM)—the worsening of symptoms that happens after physical or mental activity in ME/CFS and long COVID. They found the questionnaire is reliable and accurately distinguishes between people with and without long COVID, making it a useful tool for German-speaking patients and doctors.
