dc.description.abstract | Background. Illusions that alter perception of the body provide novel opportunities
to target brain-based contributions to problems such as persistent pain. One example
of this, mirror therapy, uses vision to augment perceived movement of a painful limb
to treat pain. Since mirrors can’t be used to induce augmented neck or other spinal
movement, we aimed to test whether such an illusion could be achieved using virtual
reality, in advance of testing its potential therapeutic benefit. We hypothesised that
perceived head rotation would depend on visually suggested movement.
Method. In a within-subjects repeated measures experiment, 24 healthy volunteers
performed neck movements to 50o of rotation, while a virtual reality system delivered
corresponding visual feedback that was offset by a factor of 50%–200%—the Motor
Offset Visual Illusion (MoOVi)—thus simulating more or less movement than that
actually occurring. At 50o of real-world head rotation, participants pointed in the
direction that they perceived they were facing. The discrepancy between actual and
perceived direction was measured and compared between conditions. The impact
of including multisensory (auditory and visual) feedback, the presence of a virtual
body reference, and the use of 360o
immersive virtual reality with and without threedimensional
properties, was also investigated.
Results. Perception of head movement was dependent on visual-kinaesthetic feedback
(p = 0.001, partial eta squared = 0.17). That is, altered visual feedback caused a
kinaesthetic drift in the direction of the visually suggested movement. The magnitude
of the drift was not moderated by secondary variables such as the addition of illusory
auditory feedback, the presence of a virtual body reference, or three-dimensionality of
the scene.
Discussion. Virtual reality can be used to augment perceived movement and body
position, such that one can perform a small movement, yet perceive a large one. The
MoOVi technique tested here has clear potential for assessment and therapy of people
with spinal pain. | |
