However, little information is available on the effect of wearing a collar on postural stability. The purpose of this study was therefore, to investigate the effect of cervical collar in neutral and 20 degrees extension of head and neck on balance. Materials & Methods: In this Quasi-experimental study, 36 healthy subjects volunteered to take part in the study through convenient simple sampling method. Data on anteropoterior (AP) and mediolateral (ML) displacement of center of pressure (COP) and AP, ML and total sway velocity were collected in four different test positions of neutral head and neck with and without cervical collar and extended head and neck with and without cervical collar. Paired Sample T-test was employed for statistical evaluation. Results: No statistically significant different (P LA eng UL http://rehabilitationj.uswr.ac.ir/article-1-661-en.html M3 ER -
