Effect of the Enriched Environment on the Risk of Relapse: Clinical Study Combining Physical Activity With Mindfulness in Virtual Reality

This clinical study investigates the effects of enriched environment on the risk of relapse in alcoholic patients.

135 patients hospitalized for an alcoholic addiction will be recruited and randomized in two groups: one group will receive standard of care, the other group will receive a treatment with enriched environment.

The enriched environment consists of six sessions of virtual reality (20 minutes) in a multi-sensory pod and six sessions (20 minutes) of bike activity with cognitive tasks while pedalling.

The multi-sensory virtual reality pod allows mindfulness practice and allows patients to be in immersive situations that may trigger cues in order to help them in craving management.

The bike consists in the combination of a pedal set and a touch pad on which cognitive training games are offered. This tool thus makes it possible to simultaneously stimulate motor skills and cognition by means of bicycle-game coupling.

Patients are then followed during 3 months and a half.

  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Interventional Group

Patients complete a measurement session at inclusion visit (Day 1). These measures include an assessment of explicit and implicit craving, a measure of mindfulness skills and a measure of the perceived richness (in stimuli) of daily environment. After inclusion visit, patients randomized in the interventional group will have 6 sessions of enriched environment (from Day 2 to Day 9).

The enriched environment includes:

  • the multisensory virtual reality pod offers sessions of 20 minutes of mindfulness in immersive situations. Some immersive situations are relaxing and others trigger cues in order to improve craving management;
  • the cognitive bike offers training sessions of 20 minutes. The patient pedals while using a touch pad with cognitive training games. This simultaneously stimulate motor skills and cognition by means of bicycle-game coupling.

A second measurement session takes place at Day 10. Alcoholic relapse is then evaluated at two weeks, one month and 3 months.

Six sessions of 20 minutes of mindfulness.
Six sessions of 20 minutes of cognitive bike (pedal + cognitive games).
Standard of care treatment
Active Comparator: Control Group

Patients complete a similar measurement session to the intervention arm, that include psychological tasks and questionnaires at inclusion visit (Day 1). After inclusion visit, patients randomized in the control group wil received the standard of care.

A second measurement session takes place at Day 10. Alcoholic relapse is then evaluated at two weeks, one month and 3 months.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Alcoholic relapse
Time Frame: 2 weeks

Relapse at 2 weeks (after Day 10), defined by the consumption of at least 5 glasses per occasion, or by consumption at least 5 times a week, assessed by the Time Line Follow Back, a beathalyser or a significant increase in Carbohydrate Deficient Transferrin and Gamma-GT.

We will consider a relapse to have occurred if at least one of the three indicators points to a relapse: 1) if in the TLFB the patient indicates consumption of at least 5 times per week or at least 5 drinks per occasion; 2) if there is a significant increase in CDT and GGT since the D10 blood test, and 3) If the breathalyser is positive. We will consider patients as non-relapsers if none of these indicators (TLFB, CDT and GGT, breathalyzer) is positive.

Day 10
Mindfulness skills
Time Frame: Day 10
The effect of intervention on mindfulness skills, assessed by a questionnaire (Five Facets Mindfulness Questionnaire -15)
Day 10
Alcoholic relapse
Time Frame: 1 month
Relapse at 1 month (after Day 10), defined by the consumption of at least 5 glasses per occasion, or by consumption at least 5 times a week
1 month
Alcoholic relapse
Time Frame: 3 months
Relapse at 3 months (after Day 10), defined by the consumption of at least 5 glasses per occasion, or by consumption at least 5 times a week
