Muscle energy problems and recovery after critical illness
The Role of Mitochondrial Dysfunction in Physical Recovery after Critical Illness
This project looks at whether problems with the cell’s energy makers in muscles help explain why many ICU survivors, especially Veterans, have long-lasting weakness.

What this research studies
You would join a group of 62 Veterans who survived a critical illness and left the ICU and be followed over time to track physical recovery. At scheduled visits, researchers will measure how well your muscles produce energy using lab tests and blood markers and compare those results to strength and walking tests. The team will analyze whether reduced mitochondrial oxidative capacity in muscle is linked to worse or slower recovery of physical function. Results will be used to help explain persistent weakness after hospitalization and guide future treatments.
Who could benefit from this research
Good fit: Ideal candidates are adult Veterans who recently survived a critical illness that required ICU care and who can attend follow-up visits and undergo blood and muscle testing.
Not a fit: People who were not recently in the ICU, are under 21, or cannot undergo blood draws or clinic visits are unlikely to benefit from participating.
Why it matters
Potential benefit: If successful, this work could reveal biological causes of lasting weakness after ICU stays and point to new treatments or better rehab strategies.
How similar studies have performed: Some smaller studies and preliminary data indicate mitochondrial problems after critical illness, but directly linking these energy defects to long-term physical recovery is a relatively new approach.
