Illusions - Vertigo Simulation

Illusions - Vertigo Simulation

Materials:
1. An open lawn space at least 15' by 15'
2. A yard stick or equivalent light weight stick

Procedure:
1. While standing in middle of open space, have victim hold stick on nose. Hold head as far back as possible and keep eyes focused on upper end of stick. Make several (4-5) 360s at a smooth rate.
2. Stop. Bend down at the hips and while holding the middle of the stick with one hand, place (do not drop) stick in front of you.
3. Remain bent over and step across the stick. Stand up quickly.

Effect:
1. The tilting and turning causes the inner ear canals to receive nerve messages in conflict with the normal axis.
2. The changes in position and movements place the inner ear messages in conflict to the visual messages.
3. When the exercise is done without pauses, the disrupted sense of balance is caused by vertigo.
