Virtual Reality for Recovery After Intensive Care (PICS) (VR4ICU)

8 maja 2026 zaktualizowane przez: 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.

Szczegółowy opis

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:

  1. 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.
  2. 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.
  3. 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."

Montreal Cognitive Assessment (MoCA)
Ramy czasowe: Baseline (T0), Post-intervention (T2: approx. 15-22 days from start), Follow-up 1 (T3: 30-45 days post-discharge), and Follow-up 2 (T4: 3 to 6 months post-discharge).
The MoCA is a tool used to screen for cognitive impairment. It assesses various cognitive domains including attention, concentration, executive functions, memory, language, visuoconstructional skills, conceptual thinking, calculations, and orientation. The total score ranges from 0 to 30 points, with higher scores indicating better cognitive function. For assessments conducted remotely (T3 and T4), a validated blinded/telephone version of the MoCA will be used.
Baseline (T0), Post-intervention (T2: approx. 15-22 days from start), Follow-up 1 (T3: 30-45 days post-discharge), and Follow-up 2 (T4: 3 to 6 months post-discharge).

The MRC-SS is used to assess muscle strength in six bilateral muscle groups (shoulder abductors, elbow flexors, wrist extensors, hip flexors, knee extensors, and foot dorsiflexors). Each muscle group is scored from 0 (total paralysis) to 5 (normal strength). The total sum score ranges from 0 to 60, where higher scores indicate better physical strength and motor function.

A self-report measure used to assess subjective distress caused by traumatic events (in this case, the ICU stay). It contains 22 items covering three subscales: intrusion, avoidance, and hyperarousal. Scores range from 0 to 88, with higher scores indicating a higher level of post-traumatic stress symptoms.

Each dimension has 5 levels of severity. It also includes a Visual Analogue Scale (VAS) where patients rate their health from 0 to 100. Higher index scores and VAS scores indicate better quality of life.

A 9-item multipurpose instrument for screening, diagnosing, monitoring, and measuring the severity of depression. Each item is scored from 0 to 3. The total score ranges from 0 to 27, where 0-4 is minimal depression and 20-27 is severe depression. Higher scores indicate greater severity of depressive symptoms.

A 7-item self-report questionnaire for screening and severity measuring of generalized anxiety disorder. Items are scored from 0 to 3. Total scores range from 0 to 21. Scores of 5, 10, and 15 represent cut-off points for mild, moderate, and severe anxiety, respectively. Higher scores indicate greater anxiety.

Simulator Sickness Questionnaire (SSQ)
Ramy czasowe: During the intervention period for the VR arm, after intervention (daily for up to 7 days).
A standard tool used to measure "cybersickness" symptoms in VR. It assesses 16 symptoms (like nausea, oculomotor strain, and disorientation) on a 4-point scale. This will be used to monitor the safety and tolerability of the immersive VR intervention compared to the tablet. Higher scores indicate greater discomfort.
During the intervention period for the VR arm, after intervention (daily for up to 7 days).
System Usability Scale (SUS)
Ramy czasowe: Post-intervention (T1: from the day after the last intervention (Day 8) to the day before T2).
A 10-item questionnaire used to evaluate the usability of the VR and Tablet systems. It covers aspects like complexity and ease of use. The final score is converted to a range of 0 to 100, where higher scores represent better user experience and higher system "acceptability."
Post-intervention (T1: from the day after the last intervention (Day 8) to the day before T2).
