Neuromuskuläre Manifestationen beim Long-COVID-Syndrom

The term long-COVID syndrome encompasses symptoms that occur after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, persisting over a period of several weeks, and which cannot be explained by another diagnosis. Long-COVID is considered to be a multiorgan condition. In this review article, the data regarding neuromuscular manifestations of long-COVID syndrome are summarized and evaluated based on criteria, such as effect size, plausibility, coherence, and experimental evidence. So far, myalgia and autonomic dysfunction (especially postural tachycardia syndrome) have been postulated as neuromuscular symptoms of long-COVID; however, the evidence to date is limited. In addition to very heterogeneous methodologies and different definitions of long-COVID in the clinical studies, conclusive experimental data supporting the described symptoms as a specific long-term consequence of COVID-19 are lacking.
