Virtual Reality for Recovery After Intensive Care (PICS) (VR4ICU)
8. května 2026 aktualizováno: Adriana Sampaio, University of Minho
Virtual Reality Intervention for Post-Intensive Care Syndrome (PICS): A Protocol for a Pilot Randomized Controlled Trial for Cognitive, Physical and Psychological Outcomes
The goal of this clinical trial is to learn if virtual reality (VR) helps improve thinking and memory skills in adults who have stayed in the intensive care unit (ICU). The study focuses on people who needed a breathing machine or stayed in the ICU for several days and are at risk for memory or "brain fog" issues.
The main questions it aims to answer are:
- Does using VR improve a participant's memory, attention, and thinking skills after an ICU stay?
- Does the "immersive" feel of a VR headset work better to improve these skills than using a handheld tablet?
Researchers will compare three groups to see how different types of care affect the brain:
- VR-Rehab: Participants use a VR headset to play brain-training games.
- Tablet-Rehab: Participants use a handheld tablet to play the same brain-training games.
- Standard Care: Participants receive the usual hospital care without digital brain games.
Participants will:
- Play brain-training games for 12 minutes every day for up to one week while in the hospital.
- Complete memory and thinking tests with a researcher at the start of the study and again after two weeks.
- Answer follow-up questions about their memory and thinking skills for 6 months after leaving the hospital.

Detailní popis
Study Rationale and the Immersion Hypothesis Survivors of critical illness often face significant cognitive impairments, a key component of Post-Intensive Care Syndrome (PICS). While early rehabilitation is recommended, traditional methods often struggle to address cognitive recovery in the acute ICU setting.
This trial is designed to investigate the "Immersion Hypothesis." This hypothesis suggests that the neurological engagement provided by a fully immersive virtual reality (VR) environment offers superior cognitive benefits compared to standard digital content delivered via a 2D interface. By utilizing a three-arm randomized design, the study seeks to isolate whether the therapeutic value comes from the digital exercises themselves or the physiological and psychological impact of total immersion.
Study Design and Arms
Participants are randomized into one of three parallel groups with a 1:1:1 allocation ratio:
- VR-Based Rehabilitation (VR-Rehab): Participants use a Meta Quest Pro head-mounted display (HMD) to engage in the Enhance VR platform (Virtuleap). This involves 6 specific games targeting information processing, problem-solving, attention, memory, and motor control.
- Tablet-Based Rehabilitation (Tablet-Rehab): Participants engage in the exact same cognitive exercises and gameplay durations as the VR group, but via a 2D tablet interface. This arm serves as a "digital control" to account for the effects of cognitive stimulation without immersion.
- Standard of Care (SOC): Participants receive conventional ICU rehabilitation, including physical and respiratory physiotherapy, without structured digital cognitive training.
Intervention Protocol All digital interventions are performed at the bedside with the participant positioned at a 30° to 60° angle for safety. Sessions are designed for a target "dose" of 12 minutes of active gameplay per day for up to 7 consecutive days (or until ICU discharge).
A "Minimum Therapeutic Dose" is defined for this study as the successful completion of at least 12 individual game sessions. This threshold ensures that participants have reached a level of engagement sufficient to evaluate the impact of the technology on cognitive recovery.
Procedural Rigor and Bias Mitigation
To ensure high-quality data in a non-blinded clinical environment, the trial enforces a strict separation of duties:
- Researcher Roles: Different researchers facilitate the daily intervention sessions and conduct the primary cognitive assessments. Those delivering the VR or Tablet therapy are prohibited from scoring the recovery outcomes.
- Automated Analysis: To eliminate subjective interpretation, primary group comparisons are performed using pre-developed, automated scripts in Python.
- Sanitization: Strict infection control protocols are followed, using medical-grade, non-corrosive disinfectant wipes for all hardware between uses.
Safety Monitoring Participant safety is monitored continuously during every session. Predefined stop criteria include physiological instability (such as a drop in oxygen saturation or significant changes in heart rate) or any verbal/non-verbal signs of distress or "cybersickness."
