The Influence of Neck Pain on Balance in Young People
Lee Gyu-Chang

Abstract
Purpose: The purpose of this study was to investigate balance changes in young patients with neck pain by comparing postural sway velocity and velocity moment between young patients with neck pain and healthy subjects.

Methods: The cross-sectional study enrolled fifteen young patients with over 3-month duration of the neck pain and twelve healthy subjects between the ages of 20 and 30 years old. All subjects were measured their postural sway velocity and velocity moment during quiet standing with eyes open and eyes closed conditions. We compared the differences of postural sway velocity and velocity moment between neck pain patients and healthy subjects, and between eye open and eye close.

Results: Significant differences were evident in the anteroposterior and mediolateral sway velocity, and velocity moment of center-of-pressure (COP) between patients with neck pain and healthy subjects (p<.05), and in patients with neck pain in the eyes open and eyes closed conditions (p<.05).

Conclusion: These results indicate that the balance of young patients with neck pain was worse than healthy subjects during quiet standing, and was especially lessened in the absence of vision. The finding may inform management program to decrease the balance deficits in young patients with neck pain.
