Participants wanted for exciting new research on balance function testing!

The effect of head angle on the Video Head Impulse Test (vHIT)
We are currently recruiting volunteers to take part in a research study investigating the effects of head angle on a routine test of balance function, the video Head Impulse Test (vHIT).
You may be eligible to take part if you:
· Are between the age of 18 and 70
· Have a good level of spoken communication in English
· Have no current symptoms or history of dizziness or imbalance
· Have no history of neck problems, eye conditions or neurological conditions
This experiment will involve you attending a single 30 minute test session at the Ellen Wilkinson Building of the University of Manchester. After a couple of quick eye tests, you will perform the vHIT test - a test used daily in balance clinics throughout the NHS. During vHIT, you will wear a pair of special goggles that can track both the movement of your eyes and the movement of your head. While looking ahead at a central target, the examiner will turn your head from side to side a small distance from centre in a brief motion. The reflex that exists between the ears and the eyes means that a head movement to the left is accompanied by eye movements to the right and vice versa. It is this reflex that keeps our visual world stable even when we are moving! The vHIT tests takes 2-3 minutes to complete and we will perform the test three times. Each time your head will start at a slightly different angle, either pitched slightly down, pitched slightly up or in a neutral head position.
