Abstract: 

Objective: There was no complete information about the effect of wearing a cervical collar on postural stability, despite the widespread use of it. The purpose of this study is to investigate the effect of cervical collar in neutral position and 20 degrees extension of head and neck on balance.
Materials & Methods: In this interventional and quasi-experimental study, thirty-six healthy students were conveniently selected through simple sampling method and mean scores of displacement and sway velocity of center of pressure on anteroposterior and mediolateral directions and total (in sway velocity) were measured in four different standing positions [neutral position of head and neck with and without cervical collar and 20 degrees (20o) head and neck extended position with and without cervical collar] by force platform. Paired Sample T-test was employed for statistical analysis.
Results: Mediolateral sway velocity in 20o extended head and neck position with collar increased in comparison with the neutral position significantly (P=0, 043), but the other balance parameters had no significant increases. No significant difference was found in other balance parameters of neutral position between wearing a collar and no collar. Also, there was no significant decrease in postural stability in 20 degrees extension of head and neck.
Conclusion: Wearing a cervical collar in head and neck extended position, causes postural stability decreasing, while use of it in neutral position has no acute effect on postural stability.
