Coronavirus disease 2019 (COVID-19) is associated with muscle and nerve injuries as a consequence of prolonged critical illness. We report here a case of intensive care unit-acquired weakness (ICU-AW) with bilateral peroneal nerve palsy after COVID-19. A 54-year-old male with COVID-19 was transferred to our hospital. He was treated by mechanical ventilation and veno-venous extracorporeal membrane oxygenation (VV-ECMO), from which he was successfully weaned. However, by day 32 of ICU admission, he had developed generalized muscle weakness with bilateral foot drop and was diagnosed with intensive care unit-acquired weakness complicated with bilateral peroneal nerve palsy. Electrophysiological examination showed a denervation pattern in the tibialis anterior muscles, indicating that the foot drop was unlikely to recover immediately. Gait training with customized ankle-foot orthoses (AFO) and muscle-strengthening exercises were started as part of a regimen that included a stay in a convalescent rehabilitation facility and outpatient rehabilitation. Seven months after onset, he returned to work, and 18 months after onset, he had improved to the same level of activities of daily living (ADLs) as before onset. Outcome prediction by electrophysiological examination, appropriate prescription of orthoses, and continuous rehabilitative treatment that focused on locomotion contributed to the successful outcome in this case.
