Cycling with immersive VR for ICU patients recovering from critical illness

Official title: Cycling Within an Interactive and Immersive Virtual Environment During Critical Illness: a Patient-centred Approach for Lower Limb Rehabilitation

Run by KU Leuven · NCT07894146 · Data updated 2026-11-12

In this crossover study, critically ill adults in the ICU will try three 10-minute cycling sessions to see if an immersive VR environment motivates them more than cycling with no visuals or cycling while watching a route on a TV.

Is this trial a fit for you?

Likely a good fit

Adults in the ICU who have been mechanically ventilated for at least 48 hours, are awake and able to participate in 10 minutes of cycling, and have an expected ICU stay of at least 7 more days.

Probably not a fit

Patients who are unable to cycle, have significant visual or cognitive impairments, or cannot understand Dutch, French, or English may not benefit.

What this trial studies

This randomized, within-subject crossover trial will enroll 20 adult ICU patients who have been on mechanical ventilation for at least 48 hours and are able to perform active cycling. Each participant will complete three 10-minute cycling sessions under different visual conditions (no visuals, TV route, and immersive VR) in random order on three consecutive days, with cycling resistance held constant. The aim is to determine whether the VR environment improves motivation and engagement during rehabilitation. The study is conducted at KU Leuven-affiliated centers and led by KU Leuven with Universitaire Ziekenhuizen KU Leuven as collaborators.

Why it matters

Potential benefit: If successful, VR-enhanced cycling could make ICU rehabilitation more engaging and potentially improve exercise tolerance and recovery.

How similar studies have gone: Previous research in rehabilitation has shown feasibility of VR in clinical settings, but benefit in ICU cycling is exploratory and this design tests a novel within-subject VR approach.
