Objective: The purpose of this study was to determine the normal value of cervical motion in Korean adults.
Method: Five hundred healthy subjects, 250 men and 250 women between third decades and seventh decades completed this study. The Cervical Range of Motion (CROM) instrument was used to measure six cervical motions and horizontal head motion.
Results: The elderly group had significantly less motion than the younger group for all six motions and horizontal head motions (p＜0.05). Women had greater range of cervical motions than men in all cervical motions (p＜0.05).
Conclusion: The method using the CROM instrument seems to be useful for primary and follow up test of cervical disease.
