primary motor cortex

CONCLUSION Functional magnetic resonance can show the changes of the primary motor cortex in patients with brachial plexus avulsion after C7 nerve transfer at uninjured side. The active exercise with injured extremity after operation can accelerate the conversion of cerebral compliance and is helpful for functional recovery.

结论：功能性磁共振可描绘出臂丛神经损伤健侧C7神经移位患者的大脑初级运动皮质的改变，术后积极进行损伤肢体的主动锻炼，可加速大脑可塑性的转化，有利于功能康复。
