Virtual Reality , immersion in a virtual titlted room
Virtual Reality , immersion in a virtual titlted room: The immersion in virtual reality will be based on the HTC VIVE® device and the software developed by the Virtualis Society.
Study summary
VIRGIL is a monocentric interventional study aiming to investigate the effect of immersion in a virtual tilted room on modulation of the verticality representation (postural vertical \[PV\] and visual vertical \[VV\]), which in turn might affect body orientation (head and trunk). To this end, the investigators will conduct a within-person randomized trial including post-stroke patients and healthy participants.

* Severe trunk deformation with C7 lateral \> 30 mm due to a independant cause beyond the stroke (i.e., scoliosis) or history of postural disorder
* 20 Stroke participants

Primary outcome measure(s)
Changes in the postural perception of the vertical (PV) before and during the immersion in a virtual tilted room, in stroke and healthy participants. — Days 1 and 3 if assignment to plane A or days 2 and 4 if assignment to plane B of the W2 PV consists of testing the whole body orientation in sitting, perceived as vertical by participants, in complete darkness. PV will be tested by a well-validated apparatus and paradigm (Pérennou et al Brain 2008). PV orientation will be the average orientation (in degree) of the 10 trials performed for each condition.
