Abstract:

BACKGROUND: Pain of neck and shoulder is the common clinical symptoms caused by chronic strain of the neck and shoulder soft tissue (mainly muscle). Surface lectromyography is a new noninvasive examination method for muscle activity, which can measure the muscle activity and function.
OBJECTIVE: To evaluate the neck-shoulder muscle function in patients with neck and shoulder pain, and provide theoretical basis for the application of surface electromyography and the reasonable prevention and rehabilitation of neck and shoulder pain.
METHODS: Thirty-two office staffs with unilateral neck and shoulder pain were examined with surface electromyography, and the surface electromyographies of the neck erector muscle and trapezius muscle were recorded under the posture of lowering head, lifting head, and hands up. The visual analogue scales of neck and shoulder pain were recorded before the test. Then the data were collected, and the muscle electromyography activities were compared between the pain side and non-pain side.
RESULTS AND CONCLUSION: The average visual analogue scales in patients with neck and shoulder pain was 5.03 before test. Under different postures, the original myoelectricity signals of the neck erector muscle and  trapezius muscle in the pain side were weaker than that in the non-pain side; there were significant differences in the average amplitude value of the neck erector muscle and trapezius muscle between the pain side and the non-pain side (P < 0.05). No significant difference was found in the average frequency slope value of the neck s erector muscle and trapezius muscle between the pain side and the non-pain side (P > 0.05). The results showed that, the neck and shoulder muscle activity ability decreased at the pain side of patients with neck and shoulder pain, and the office staffs with long-term seat assignments should exercise their neck and shoulder muscles regularly.
