Modifying Bodily Self-Awareness during Acupuncture Needle Stimulation Using the Rubber Hand Illusion

Figure 1

Schematic drawing of the experimental setup illustrating the rubber hand illusion with (experiment  1) and without (experiment  2) the visual expectation when participants received acupuncture stimulation on their real hand. Two small paintbrushes stroked the rubber hand and the participant’s hidden real left hand as synchronously as possible under one condition (synchronous condition) and asynchronously under the other (asynchronous condition).
