Lower-body heat therapy to improve mobility after long COVID

Official title: Physical Rehabilitation of Long COVID by Heat Therapy

Run by University of Nebraska · NCT06928116 · Data updated 2026-11-12

This test will see if at-home lower-body heat therapy can improve mobility and metabolic and vascular health in people aged 50–90 with long COVID who have ongoing fatigue or reduced physical function.

Is this trial a fit for you?

Likely a good fit

People aged 50–90 who previously had COVID-19 and continue to experience fatigue or reduced physical function for at least two months, who can walk and meet the BMI/weight limits, are ideal candidates.

Probably not a fit

People who are pregnant, breastfeeding, on hormone therapy, have orthopedic limitations that prevent walking, severe claustrophobia, or are already enrolled in exercise-based rehabilitation may not benefit or be ineligible.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Researchers will enroll adults aged 50–90 with persistent symptoms after COVID-19 and randomize them to home-based lower-body heat therapy, a sham control, or a walking intervention, with planned baseline and follow-up visits at the University of Nebraska Omaha. The trial will measure safety, tolerability, adherence, and changes in functional capacity alongside metabolic and vascular biomarkers. Heat therapy is delivered at home to assess real-world tolerability and feasibility for people who may struggle with traditional exercise-based rehabilitation. Outcomes will compare mobility and surrogate cardiometabolic markers between groups over the intervention period.

Why it matters

Potential benefit: If successful, this approach could offer a low-exertion, at-home option to improve mobility and cardiometabolic health for older adults with long COVID.

How similar studies have gone: Whole-body heat therapy has shown health benefits in other populations, but lower-body, home-based heat therapy for long COVID is relatively novel and largely untested.
