Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with documented fatigue symptoms following a COVID-19 infection.

Probably not a fit

Patients currently experiencing an active SARS-CoV-2 infection or those with pre-existing conditions that affect physical or cognitive function may not benefit from this study.

What this trial studies

This feasibility trial evaluates a new rehabilitation program called COVIDEx aimed at treating fatigue in individuals suffering from Long COVID. The study will recruit 60 participants who will be randomly assigned to either the COVIDEx program or standard care, with both groups followed for 24 weeks. The intervention consists of an 8-week multi-modal rehabilitation program with two 50-minute sessions per week. The trial employs a modified Zelen design to assess the effectiveness of the intervention under real-world conditions, ensuring comprehensive data collection on health outcomes.

Why it matters

Potential benefit: If successful, this program could significantly alleviate fatigue symptoms in patients recovering from COVID-19.

How similar studies have gone: While there have been studies addressing rehabilitation for Long COVID, this specific approach using the COVIDEx program is novel and untested.
