Sponsor's own description

The aim of this study is to investigate the effect of manipulating the optic flow speed in the virtual environment on the gait pattern during virtual reality (VR) - enhanced treadmill walking in people post-stroke. Furthermore, the study will also investigate if the level of immersion has an effect on the rehabilitation outcomes by manipulating the optic flow speed in two different VR devices: the semi-immersive GRAIL system and the fully-immersive 'Oculus Rift S' HMD.

To properly understand the results of the people with a stroke, we will also investigate the effect of manipulating the optic flow speed and the level of immersion on the gait pattern in healthy people. That way, we can investigate whether virtual reality has a different influence on the gait pattern of people with a stroke than in healthy people.
