Updated Jul 23, 2026

Abstract

Electromyography abnormalities were observed in patients with long COVID.

Persistent symptoms following SARS CoV-2 infection, known as long COVID, remain a significant health concern.
Previous findings indicated abnormalities in muscle electrical activity among patients with long COVID.
This study focuses on evaluating the long-term effects on the neuromuscular system in individuals experiencing long COVID.

Simplified

Persistent symptoms after SARS CoV-2 infection, often designated as "long COVID", continue to be an ongoing health issue. Previously, we reported electromyography (EMG) and single fiber EMG (SFEMG) abnormalities in long COVID. This study aimed to assess the long-term neuromuscular manifestations of long COVID.
