Powered lower-limb exoskeleton training for adults with prolonged mechanical ventilation
Official title: Physiological and Functional Adaptations Associated With Robot-assisted Lower-limb Activity in Ventilator-dependent Hospitalized Patients
Run by Fu Jen Catholic University · NCT07445035 · Data updated 2026-11-12
We are testing whether using a powered leg exoskeleton during training can improve leg strength, breathing measures, and recovery time for people who have been on a ventilator for a long period.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults on prolonged mechanical ventilation who can sit upright for at least one minute and provide consent (or have a legal representative).
✕Probably not a fit
Patients who cannot follow instructions, have complete leg paralysis, unhealed leg ulcers, severe cardiac or orthopedic conditions, or other high-risk exclusions may not benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
The trial will evaluate the effects of exoskeleton-assisted training on lower limb strength, respiratory parameters, 28-day ventilator-free days, and length of hospital stay in adults with prolonged mechanical ventilation in a respiratory care center. Thirty participants will be recruited and assigned to exoskeleton-assisted training or standard care in a 1:1 fashion, with matching on gender, age, and ICU length of stay. The study is conducted at Fu Jen Catholic University Hospital in collaboration with Fu Jen Catholic University. Outcomes will inform how rehabilitation and respiratory care might be integrated for this population.
Why it matters
Potential benefit: If successful, patients may gain improved leg strength and shorter ventilator dependence and hospital stays.
How similar studies have gone: Exoskeletons have shown benefits for leg strength and endurance in other populations, but similar evidence in prolonged mechanical ventilation patients is limited.
