We collected and analysed the detailed clinical information as follows: the type and order (in case of different types) of COVID-19 vaccine, laterality of symptom presentation, timeline regarding the vaccination, symptom onset and nadir, clinical presentation, motor grade at nadir, the results of electrodiagnosis, brachial plexus MRI, cerebrospinal fluid (CSF) analysis, treatment regimen and the outcomes.We identified 12 patients (7 men and 5 women) who developed PTS after a receipt of COVID-19 vaccine. Clinical features of the patients are summarised in table 1 (and online supplemental figure). Age ranged between 23 and 81 (average 51). Vaccination … ER -
