Electromyohgraph, Neck Pain
Conditions
Brief summary
Despite the important role of axioscapular muscles electromyography and cervical posture as outcomes for the management of chronic neck non specific pain , there is gab of evidence that highlight their association to the commonly used neck disability index. The quest to improve outcomes for individuals suffering from chronic nonspecific neck pain is underscored by the need to identify key prognostic variables that can guide clinical decision-making and intervention strategies. This study seeks to bridge the gap in research by examining the association between neck disability index score, cervical sagittal curvature, and axioscapular muscles electromyography in forms of both trapezius and levator scapula root mean squares to indicate muscular activities and median frequencies to indicate muscular fatigue.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Neck disability | at the enrollment | Neck disability will be measured using the neck disability index. It is a 10-item questionnaire. The patient will be asked to respond by selecting the checkbox next to each statement that most accurately reflect him/her. |
| Curvature angle of the cervical spine | at the enrollment | A flexible ruler (ati, FC-700R, Taiwan) will be used to measure the cervical spine curve. To calculate the angle, the patient's elbows will be resting on the armrest directly below the acromion as the patient sat in a chair with his feet flat on the floor, and the ruler will firmly press against the patient's upright cervical spine between the occiput and the seventh cervical spinous process. A mathematical equation will be used: angle (Q) =arc tan (2b / a). whereas: a, Length between the two endpoints of the cervical curve; b, Length of the perpendicular from the midpoint of line a to the curve |
| root-mean-square value (RMS) of Surface electromyography for both upper trapezius and levator scapula | at the enrollment | electromyography (MyoSystemTM 1400A, Noraxon Inc, 15770 N) will be used to measure: * the maximum voluntary isometric contraction of both upper trapezius and levator scapula for 3 trials. * Writing task electromyography amplitude for 15 minutes, a semistatic load, after the MVIC evaluation Finally, root-mean-square value (%) of both upper trapezius and levator scapula will be calculated as : Writing task electromyography amplitude divided by the average of the three maximum voluntary isometric contraction trials. |
