To explore the effect of modified Shengyu decoction on spinal cord function of cervical spondylotic myelopathy after operation.Method: A total of 68 cases diagnosed definitely and operated

were randomly divided into rehabilitation exercise treatment combined with modified Shengyu decoction group（group A）

and rehabilitation exercise treatment（group B）.Group A included 32 cases

and 36 cases were in group B.After operation

the cases were treated by anti-inflammatory

rehabilitation treatment

traditional Chinese medicine

etc.Spinal cord function of cervical spondylotic myelopathy was evaluated by JOA score at preoperative and 1

2

4

6 weeks and 3 months after operation.Result: The JOA scores for patients in both groups were significantly improved compared with that of pre-operation（P < 0.05）

but there was no significant difference between the two groups after one week.And JOA in group A were significantly better than that in group B after 2

4

6 weeks and 3months

and the difference was significant（P < 0.05）.Conclusion: Rehabilitation exercise treatment and rehabilitation exercise treatment combined with modified Shengyu decoction can improve the spinal cord function for cervical spondylotic myelopathy after operation.But the effect of combined with modified Shengyu decoction is more significant.
