Relationship Between Musculoskeletal, Sensorimotor and Functional Factors and Nonspecific Chronic Neck Pain

Study Overview
=================
Brief Summary
-----------------
Several factors have been associated with neck pain. Controversy exists regarding the degree of association between some of these factors and neck pain. Information regarding the degree of association of each factor to neck pain is needed for effective prevention and appropriate treatment strategies. The aim of this study is to investigate the association among musculoskeletal, sensorimotor factors and functional disability and occurrence of chronic nonspecific neck pain.

Conditions
-----------------
Neck Pain
