Result:In the cervical myelopathy patients,no significant difference was found among the results of Hoffmann reflex at neutral position,30°,60°of dorsiflexion,but there was significant difference between the results of Hoffmann reflex at15°of palmar flexion and that at neutral position,30°,60°of dorsiflexion.
Method:37patients diagnosed as cervical myelopathy as well as50normal persons were examined for Hoffmann reflex respectively at15°of palmar flexion,neutral position and30°,60°of dorsiflexion,the result of which was do with statistics.
The indicati ons for this procedure include cervical disc herniation, cervical myelopathy, ra diculopathy, and traumatic cervical disc injury on C3,4 to C5,6 segments.
Among them, 11 cases were diagnosed cervical myelopathy(CM), and 9 cases coexisted of CM. The authors considered=(1) CM usually was misdiagnosed as MND;
Objective:To explain the adaptive symptom for each surgery by comparing the results of 64 cases of cervical spondylosis myelopathy(CSM)patients after surgery with anterior or posterior approach.
Methods The ultrastructure of cervical disc herniation (CDH),cervical spondylosis myelopathy (CSM) and CED of fetal,normal adults,were obtained by electronic microscope.
Methods 86 cases with cervical spondylitic myelopathy were treated with anterior decompression, bone graft and interbody fusion with cage (C 3~4 ) or plate fixation C 5~6 ,C 6~7 . The neural function recovery, fusion, and implant complication were monitored.
Objective To investigate the veracity of cortical somatosensory evoked potential (CSEP) and the influencing factors of manipulation of CSEP monitoring during the operation for cervical spondylitic myelopathy (CSM).
Conclusion This method for cervical spondylitic myelopathy has the advantages of few complications, simple manipulation, immediate stability, prevention of bone graft displacement, unneccessary for plaster immobilization and significant improvement of bone fusion rate.
The Change of Blood Flow Velocity of Vertebral Artery Basilar Artery(VA-BA) and Observition of Therapeutic Effection before and after Treating Cervical Spondylosis of Type Spinal Cord by Pluse Magnetic Therapy
Objectives The purpose of this study was to consider the active mechanisms and therapeutic effection of pluse magnetic therapy. Method 57 patients with documented cervical spondylosis of type spinal cord were treated by piuse magnetic therapy, while blood flow velocity of VA - BA was checked by Transcranial Doppler before and after treatment, we selected 10 healthy adults randomly, their conductive velocity of the midial nerve and the ruler nerve was determined by Sports Nerve Conductived velocity Surveying instrument before and after pluse magnetic therapy.
Twenty-two patients with localized lesions of the central nervous system (unilateral cerebral ischaemia, cervical myelopathy, spinal tumour, familial spastic paraplegia) underwent neurophysiological evaluation of sensorimotor deficits of the leg.
There were 20 patients with cervical myelopathy, 15 with intrinsic cord abnormalities including syrinxes, 7 with spinal cord infarcts and 7 with other conditions such as tropical spastic paraparesis and hereditary paraparesis.
