Background and study aims Neck pain is a very common condition, which can be cause great discomfort and restriction of movement. Patients with neck pain often have visual problems however the reason for this is unknown. One possibility is that the amount of neck movement a person undertakes can influence the eye function. Many patients with neck pain may move their necks less to avoid pain, which may be causing the visual problems. The aim of this study is to look at whether a lot of movement or restricted movement of the neck has an effect on eye function in healthy people with no neck pain, to try to find the out if there is link between neck movement and visual problems. Who can participate? Adults with no neck pain who are able to move their necks freely and normal or corrected-to-normal vision. What does the study involve? Participants are randomly allocated to undertake two tests spaced one week apart in a different order. Before and 20 minutes after each test, participants have their eye function (measuring of the eye stabilization reflexes) measured. One test involves moving the neck around extensively for 20 minutes. The other test involves wearing a stiff neck collar that restricts movement for one hour. The measurement of eye function will be in a darkened room and lasts around 20 minutes. It involves having to look straight forward while the chair they are sitting on is rotating, while the position of their eyes is measured with an infrared eye tracking device. Two weeks later, 11 participants return to repeat the condition with the neck collar, after wearing it for two hours. The eye function tests are repeated before and 20 minutes after wearing the collar. What are the possible benefits and risks of participating? There are no direct benefits for participants taking part in this study. Where is the study run from? Erasmus MC (Netherlands) When is the study starting and how long is it expected to run for? August 2014 to May 2015 Who is funding the study? Erasmus MC (Netherlands) Who is the main contact? Miss Britta Ischebeck [email protected]
