Recovering muscle strength and mobility after critical illness

Muscle and physical function recovery after acute critical illness

NIH-funded research University of Kentucky · NIH-11172557

This research follows adults who survived critical illnesses like ARDS to learn how their muscles and movement recover during the first year after leaving the hospital.

What this research studies

If you survived a serious critical illness such as ARDS or sepsis, researchers will follow you over the first year after hospital discharge to track muscle and physical recovery. They will collect small, repeated muscle tissue samples from the same patients and pair those with physical function tests, patient-reported quality-of-life measures, and clinical data. Laboratory measurements will include muscle protein turnover, cellular signaling pathways, and markers of damage, inflammation, and immune response. The aim is to link cellular changes in muscle with real-world recovery outcomes so future treatments and rehabilitation can be better targeted.

Who could benefit from this research

Good fit: Adults (generally 21 years and older) who survived acute critical illness such as ARDS or acute respiratory failure and are within the first year after hospital discharge.

Not a fit: People under 21, those without a recent critical illness, or anyone unable or unwilling to undergo serial muscle sampling and repeated clinic visits are unlikely to benefit from participating.

Why it matters

Potential benefit: This work could lead to targeted treatments or rehabilitation strategies that help survivors regain muscle strength and independence after critical illness.

How similar studies have performed: Prior research has linked inflammation and inactivity to post-critical-illness muscle loss, but serial, within-patient muscle biopsies combined with year-long functional follow-up are relatively novel.
