Abstract
Around three years ago, in the special issue on augmented and virtual reality in rehabilitation, the topics of simulator sickness was briefly discussed in relation to vestibular rehabilitation. Simulator sickness with virtual reality applications have also been referred to as visually induced motion sickness or cybersickness. Recently, study on cybersickness has been reported in entertainment, training, game, and medical environment in several journals. Virtual stimuli can enlarge sensation of presence, but they sometimes also evoke unpleasant sensation. In order to safely apply augmented and virtual reality for long-term rehabilitation treatment, sensation of presence and cybersickness should be appropriately controlled. This issue presents the results of five studies conducted to evaluate visually-induced effects and speculate influences of virtual rehabilitation. In particular, the influence of visual and vestibular stimuli on cardiovascular responses are reported in terms of academic contribution.
Highlights
Background on the Behavior of BiosignalsThe autonomic nervous regulation would be evaluated during a recovery phase because it regulates cardiovascular functions after extensive exercise or stress
Current virtual reality (VR) technology expands sensory effects and physical activities, and the potential effects are expected in rehabilitation engineering [2]
There is a large difference in time-scale between sensory activity and autonomic nervous activity (ANA) (Fig. 2)
