Spinal cord injury (SCI) is a kind of severe disease with high morbidity and complications. At present, electroacupuncture has certain advantages in treating motor sensory dysfunction, neuropathologic pain, neurogenic bladder and intestinal dysfunction after spinal cord injury. However, previous clinical studies of acupuncture neglected the brain, which is closely related to the structure and function of spinal cord.So,the aim of this study is to observe and analyse the impact of the changes of gray and white matter volume on whole brain and brain functional re-establish,to reveal the neuroimaging mechanism of improving the motor sensory functions of patients with spinal cord injury, and to provide a theoretical basis for the clinical application of electroacupuncture.

Electroacupuncture： Major acupoints: Jiaji points. With urinary and stool dysfunction:+Shenshu (BL23) ,Huiyang(BL35). Localization:Jiaji points of the upper 1 and the lower 1 segment of the Spinal cord injury plane, a total of 4 points. Operation: Insert Jiaji points By using Hwato-brand disposable acupuncture needles(0.30mm\*50mm), with 0.5 inch from the median line and a depth of 50 to 60mm with perpendicular insertion.Then, participants will receive electroacupuncture treatment by connecting Han's pain irritant instrument (HANS100A) for 30min with the stimulation frequency of 2 /100 Hz and intensity of 1-2mA. Once a day, 5 days a week and rest 2 days, a week is one course and the duration need 12 courses. Routine rehabilitation training: Same as Routine rehabilitation training Group.
Routine rehabilitation training: Participants with good spinal stability will receive sitting training as early as possible, and will carry out standing training if participants had no adverse reactions (postural hypotension, etc.) after sitting training. Muscle strength training will be performed in recovery phase, and functional movement training will be selected according to participants' conditions. Functional movement training and transfer training will be performed for 20min each time and once a day;Standing and walking training, 2 times a day, 30min each time.

RECRUITINGBrain structure data(Changes of gray and white matter volume on whole brain based on fMRI)
The 3D MPRAGE image data collected by fMRI will be recorded and exported on a CD, and then will be processed and analyzed by VBM8.
Time frame: Before intervention; the end of the 3rd month when treatment finished.
Brain function data(Changes of ALFF value and FC value of the whole brain based on fMRI)
The REST fMRI image data will be recorded and exported to a CD, and then will be processed and analyzed with REST software and seed point method to calculate the ALFF value and FC value of the whole brain.
Time frame: Before intervention; the end of the 3rd month when treatment finished.
Change in ASIA (American Spinal Injury Association) grade
To assess the motor function and the sensory function. The motor function will be evaluated according to the scores of five key muscles and muscle strength in both lower limbs.This score can reflect the degree of neurological impairment associated with the SCI, with lower score indicating greater impairment. Score ranges from 0-25 for each extremity, with maximum scores of 50 for the upper limbs and 50 for the lower limbs. The sensory function will be evaluated according to the scores of bilateral pain sensation and tactile sensation in 14 key sensory points in both lower limbs. This score can reflect the degree of neurological impairment associated with the SCI, with lower score indicating greater impairment. Score ranges from 0-56 points each for light touch and pin prick (sharp/dull discrimination) modalities, with a maximum total score of 112 points per side of the body.
Time frame: Before intervention; after 6 weeks of treatment;the end of the 3rd month when treatment finished;fellow-up period at the 6th month.
Change in Modified Ashworth Scale(MAS)
To assess the muscle tone.MAS grades as follows: 0: No increase in muscle tone.1: Slight increase in muscle tone, manifested by a catch and release or by minimal resistance at the end of the range of motion when the affected part(s) is(are) moved in flexion or extension.1+: Slight increase in muscle tone, manifested by a catch followed by minimal resistance through the remainder of the range of motion but the affected part(s) is(are) easily moved.2: More marked increase in muscle tone through most of the range of movement, but the affected part(s) is easily moved.3: Considerable increases in muscle tone, passive movement difficult.4: Affected part(s) is (are) rigid in flexion or extension.
Time frame: Before intervention; after 6 weeks of treatment;the end of the 3rd month when treatment finished;fellow-up period at the 6th month.
Change in Modified Barthel Index(MBI)
To assess the ability of the patient to perform daily activities.It comprises 10 items regarding activities of daily living and mobility and assesses feeding, transfer from wheelchair to bed and back, self-care, bathing, walking, climbing stairs, dressing, and bladder and bowel continence. Scoring is based on whether the patient requires help or not in performing any of the above mentioned activities.Scale range: 0-100.Higher score means better function and less dependence.
Time frame: Before intervention; after 6 weeks of treatment;the end of the 3rd month when treatment finished;fellow-up period at the 6th month.
