Rear portion, C1 is positioned at front portion, vola little toe heel and i.e. checks the inwardly turned side position of movement locus, and B1 is between A1, C1, and D1 is positioned at
Medial plantar correctly checks the end of movement locus, when micro controller detects that original position A1 starts when having push action
Babinski levies inspection action record process, and the change in electric that micro controller exports according to sensor device, in conjunction with in micro controller
The intervalometer in portion, final data is wireless passes to computer, by computer analysis complete whole Babinski levy mould analog information and
Recording process.
4. the method for work of the sensor device for analog neuron reflex system as claimed in claim 3, it is characterised in that
The method of the simulation that described Oppenheim levies simulation people is specific as follows: before examiner's thumb and forefinger edge simulation people's tibia
Edge firmly sliding pressure from top to bottom, checkpoint is positioned at simulation people's tibia sites, is respectively arranged with string pressure detecting point in the tibia left and right sides,
Two row test point quantity are identical, symmetrical distribution, and the most position encoded being respectively of left column test point presses A5, B5, C5, right
The most position encoded D5, E5, the F5 of being respectively of row test point, wherein (A5, D5) (B5, E5) (C5, F5) is symmetrical test point,
When micro controller detects that original position test point A5 or D5 starts Oppenheim when having push action and levy inspection action record
Process, the change in electric that micro controller exports according to device, in conjunction with the intervalometer within micro controller, final data is wireless passes to meter
Calculation machine, is completed whole Oppenheim by computer analysis and levies analog information and recording process.
