Previous research has shown a positive relationship between activation of the upper trapezius muscle and flexion of the cervical spine muscles during computer operation3, 4. Cervical motion is now considered to consist of upper cervical motion and lower cervical motion5. Increased forward head movement, specifically combined with lower cervical flexion and upper cervical extension, might result in tightness of the cervical extensors as well as increased compressive forces in the articulations of the cervical spine2, 4.
Thus, therapists should evaluate upper and lower cervical motion separately in computer workers with neck pain; however, few studies have assessed this. The upper trapezius and levator scapular muscles can become painful after computer work 2, 5. These muscles are also important in the treatment of neck pain 2.
Therefore, the purpose of this study was to compare the upper cervical flexion and cervical flexion angles of computer workers with upper trapezius and levator scapular pain.
The upper trapezius and levator scapular pain groups were defined as the subjects with a pressure pain threshold below 6 lb in the respective muscles. The dolorimeter consists of a metal probe that can measure pressures up to 20 lb in 0.
In this study, the pressure was applied with the dolorimeter at a right angle to the body to measure the pressure pain threshold.

All subjects provided their informed consent before participating in the study. Each participant was assessed in terms of upper cervical flexion angle and total cervical flexion angle using a cervical range of motion instrument CROM; Performance Attainment Flexin, St. The sagittal- and frontal-plane gravity goniometers measure flexion extension and lateral flexion, respectively.
Each participant was seated on a standard folding chair flxeion fitted with the CROM device. For the selective upper cervical flexion angle measurement, a pressure biofeedback unit was placed between the wall and the Corresponding author. In this position, the plastic bag was inflated to a pressure of 20 mmHg during upper cervical flexion motion. The subjects performed selected computer work using the program Hansoft. The SPSS software ver. However, we suggest that a treatment approach for the upper cervical portion is needed for computer workers with levator scapular muscle pain.
Thus, an intervention or rehabilitation to address limitations in total cervical range of motion must first include an intensive approach for recovery of lower cervical motion. For selective and effective intervention for neck pain, therapists should evaluate upper and lower cervical motion individually.
To enable this, researchers should develop a new device such as an upper cervical range of motion measurement tool. Man Ther, Upper crossed syndrome and its relationship to cervicogenic headache.
