Hypothesis: We hypothesize that post-COVID-19 patients have a significantly higher apnea-hypopnea index (AHI) during sleep compared to healthy controls.~15 post-COVID-19 patients and 15 healthy controls will perform a baseline assessment on day 1 including a 1-minute sit-to-stand test (STST), post-COVID functional scale (PCFS), Ordinal Scale for Clinical Improvement (OSCI), history of COVID-19, social anamnesis, Pittsburgh Sleep Questionnaire and subjective limitations of sleep.~On day 4, after an initialization phase for WHOOP strap (a digital fitness and health coach), all patients performed a single night sleep assessment in a sleep lab via Polysomnography and WHOOP.
After acute infection, patients with coronavirus disease 2019 (COVID-19) often suffer from persisting symptoms for more than 3 months (post COVID-19). Sleep disorders (31%) have already been assessed by questionnaires and interviews in post-COVID-19, but have not yet been proven by polysomnography (PSG), the gold standard for sleep testing. This study aimed to measure sleep characteristics in post-COVID-19 patients.
