COVID-19's hidden toll: muscle wasting in the ICU
NCT ID NCT04849624
First seen Sep 15, 2026 · Last updated Sep 16, 2026 · Updated 1 time
Summary
Researchers at the University of Malaya are studying how COVID-19 affects muscle loss and strength in critically ill patients. They will compare quadricep muscle thickness and cross-sectional area, along with handgrip and knee extension strength, between COVID-19 and non-COVID-19 patients admitted to the intensive care unit. The study aims to understand whether COVID-19 worsens muscle wasting during critical illness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If researchers find that COVID-19 patients lose muscle faster or more severely, this could guide earlier or more intensive rehabilitation for critically ill patients.
- What could go wrong
- This is a small observational study of 59 people, so it cannot prove cause and effect. Ultrasound and strength tests can vary between operators, and the findings may not apply to other hospitals or patient groups.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
A total of 30 COVID-19 ICU patients as per the eligibility criteria will be recruited. A total of 20 non-COVID-19 ICU patients that are matched by age (+/- 10 years old), sex and ventilation mode (mostly will be with lung pathology) will be enrolled to compare their change in muscle mass and muscle strength at hospital discharge with COVID-19 ICU patients.
