OBJECTIVE
The aim of this study was to examine the effects of deep branches of cervical plexus on trapezius muscle.
METHODS
The evoked electromyography of 32 trapezius of 16 SD rats was examined in different time and results obtained were processed by statistical methods.
RESULTS
After cutting the accessory nerves, stimulating the deep branches of cervical plexus evoked the myoelectricity, the myoelectricity results varied according to different time.
CONCLUSION
The deep branches of cervical plexus are another important motorial supply to trapezius muscles. After cutting the accessory nerves, if the branches were undamaged, the shoulder's function would be greatly preserved.
目的
本研究旨在探讨颈丛深支对斜方肌的影响。
方法
对16只SD大鼠的32块斜方肌进行不同时间的诱发肌电图检查，并对所得结果进行统计学处理。
结果
切断副神经后，刺激颈丛深支可诱发肌电活动，肌电结果随时间不同而变化。
结论
颈丛深支是斜方肌的另一重要运动神经支配。切断副神经后，若该分支未受损，肩部功能可得到很大程度的保留。
