Cervical motor nerve root conduction time measuring device and method

Abstract

The invention discloses a cervical motor nerve root conduction time measuring device and method. The cervical motor nerve root conduction time measuring device comprises an information acquisition unit, a preliminary examination, calculation and analysis unit and a result archiving output unit, wherein the information acquisition unit comprises a myoelectric evoked potential instrument and a magnetic stimulation instrument, and the preliminary examination, calculation and analysis unit comprises a preliminary examination module and a calculation and analysis module. The method comprises the steps that the conduction time of the incubation periods of an M wave and F wave of the nerve is measured, and the conduction time of the motor nerves near the cervical vertebra is measured; the two periods of conduction time together with personal information, personal historical information and standard information are transmitted into the preliminary examination module of the preliminary examination, calculation and analysis unit; finally, result archiving output is carried out. The cervical motor nerve root conduction time measuring device and method solve the problem that the sensitivity and specificity are reduced due to the facts that long-range conduction significantly 'dilutes' the assessment of the conduction function of the proximal cervical nerve roots, the specificity is poor, and the long-range conduction is possibly covered by normal conduction by providing a normal value of the conduction time of the cervical nerve of Chinese Han normal people.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device and method for measuring the conduction time of cervical motor nerve roots. Background technique [0002] Existing examinations, such as magnetic resonance (MRI) and CT imaging techniques, are difficult to display cervical radiculopathy well, and can only show anatomical structures, but cannot prompt cervical nerve root function. The results are often serious with clinical cervical radiculopathy. In addition, these tests are not suitable for people with spatial phobia. Traditional electrophysiological methods are mostly used to evaluate the function of the distal peripheral nerve, but the F wave induced by super-strong stimulation runs through the entire length of the peripheral nerve of the limb, and can only indirectly evaluate the function of the proximal nerve. In 1950, Magladery and McDougal first discovered that there was a small electric wave after the co...

Problems solved by technology

[0008] The object of the present invention is to provide a kind of cervical motor nerve root conduction time measurement device and method, the present invention detects the cervical nerve root conduction time of Chinese Han normal population of different ages and genders in normal population, and provides the cervical nerve root conduction time of Chinese Han normal population. The normal value of the conduction time solves the problem of the existing technology that the evaluation of the conduction function of the proximal cervical nerve root is significantly "diluted" due to the long-distance conduction, and the specificity is poor, which may be covered by the normal conduction, resulting in a decrease in sensitivity and specificity
