VERARE_2 Efficacy of the Observation of Virtual Motor Actions for the Improvement of Gait in Patients With ICU-weakness

Condition(s) studied

Investigational drug(s) / intervention(s)

Virtual Reality Observations: If the patient is included in the Virtual Reality group, they will be asked to observe 1 time per day for 9 days for 5 minutes Virtual Motor Actions (avatar moving in a virtual environment) using a headset. Virtual Reality, followed by 5 minutes of relaxation performed using soothing music played through headphones.

Relaxation: If the patient is included in the Relaxation group, they will be offered 10 minutes of relaxation performed using soothing music played through headphones once a day for 9 days.

Study summary

After hospitalization in Intensive Care (Intensive Care Unit or Continuing Care Unit), approximately 50% of patients usually present with intensive ICU-weakness, i.e. damage to the nerves and muscles secondary to immobilization and to the treatments that must have been used. This condition will delay the resumption of walking in these patients, their discharge from hospital and impair their autonomy in the daily life.

The recent international literature is in favor of early rehabilitative management of these patients, which should ideally be started in the intensive care unit. However, this is not always possible, due to the possible lack of physiotherapists in the services on the one hand, due to the fatigue of the population concerned and the existence of unstable medical conditions which do not always allow the use of recommended rehabilitation techniques on the other hand.

Virtual Reality (VR) environments are widely used for the assessment and rehabilitation of patients with neurological pathology. VR allows the user to be active in simulated activities and offers many advantages for the rehabilitation of motor functions in patients with neurological diseases. VR tools used to create action observation, motor imagery and sensations or even the illusion of movement in particular, have already shown their effectiveness in recovering and improving walking in different populations, especially after a stroke, in patients with Parkinson's Disease or Multiple Sclerosis. The role of the embodiment in VR appears promising in immersing participants in a controlled environment and creating movement's illusions.

The Virtual Reality tool designed consists of virtual environments presented using a Virtual Reality headset where an avatar (double) of the hospitalized patient will be represented, who will perform a walking motor task (involving his lower limbs ) in several different virtual environments (sets). In the present study named VERARE\_2, the patient will be asked to observe walking actions and imagine performing them as they will be performed by the avatar in the virtual environment.

This VERARE\_2 protocol aims to assess the effectiveness of the Observation of Virtual Motor Actions on the speed of gait recovery in hospitalized patients with IUC-weakness and in the intensive care units and continuing care units of the Rennes University Hospital.
