Upper Cross Syndrome Rehabilitation Strengthening of the Dorsal Erector Muscles

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine which treatment is more effective for chronic neck pain associated with Upper Cross Syndrome.

Detailed Description
-----------------
Patients will divided in two groups, control and intervention. Control Group will do exercises of strengthening of Deep Cervical Flexors, Shoulder External Rotators and Adduction of Scapulae. Intervention group will do the same plus Strengthtening of Erector Thoracic.
