简要总结
This study investigates one of the mechanism factors of neck pain. Cervical lordotic angle alterations affect the tension of serratus anterior muscle. Expected result that the long thoracic nerve can be affected in this situation, and could be observed the functional changes of the nerve with serratus anterior electromyographic findings.
详细描述
Different methods exist in order to evaluate muscle function. For the neck pain, the most commonly used method by researchers and clinicians are spot radiography and surface electromyography (sEMG). Radiographs can be used for the kyphotic angle or cervical lordotic angle measurements. Parameters that can be studied by EMG are amplitude, timing, conduction velocity, fatigability and characteristic frequencies/patterns.
The long thoracic nerve innervates the serratus anterior muscle. This nerve arises from the anterior rami of three spinal nerve roots: the fifth, sixth, and seventh cervical nerves (C5-C7) The nerve descends through the cervicoaxillary canal behind (posterior to) the brachial plexus and the axillary artery and vein, resting on the outer surface of the serratus anterior. The Serratus anterior electromyography, the needle can be inserted into the muscle superficially to the fourth to sixth rib in the medial or posterior axillary line. The usual nerve latency time is between 2.6-4 ms.
In this study, the results of serratus anterior muscle EMG activity and postural cervical angle alterations (lateral radiography) in patients with chronic mechanical neck pain will be compared with healthy volunteers without neck pain.

研究组 & 干预措施
Control group
The healthy volunteers recruit in this group. All inviduals will undergo lateral cervical spot radiography and serratus anterior needle electromypography
干预措施: Radiography (Radiation)
Cervical postural related neck pain
Patients recruit in this group who has a neck pain without radiculopathy. If the patient examination shows neurologic deficits, this patient will exclude in this study. All patients will undergo lateral cervical spine spot radiography and serratus anterior needle electromyography. Cervical segmental angle measurements will be done in all patients.

时间窗: 1 hour
Pain is a sensory and emotional experience, modified by multiple factors, including meaning, context, previous pain experience, culture, gender, expectation, anxiety, depression, fear, family and social factors. Patients admitted to hospital experience a high prevalence of moderate and severe pain. The VAS (Visual Analog Scale, 0 mm "no pain", to 100 mm," the worst pain possible ") is used to assess chronic neck pain. The authors aim to find a correlation between factors either neck pain (with VAS), cervical lordosis angle and long thoracic nerve electrophysiological results.
