Cov koob electrode siv hauv kev kuaj electromyography yog hu ua ib rab koob electrode pov tseg (tseem hu ua electromyography koob los yog concentric needle), uas yog ib tug bipolar nyias koob zoo li electrode. Thaum lub sij hawm kuaj xyuas, cov electrodes tau muab tso rau hauv cov leeg, thiab cov nqaij ntshiv ntawm cov nqaij ntshiv nyob rau hauv so thiab kev cog lus hauv lub xeev tau nthuav dav los ntawm lub teeb liab amplifier, uas tom qab ntawd tso tawm ntawm oscilloscope.
Nta:
1. Koob: Qhov chaw txiav ntawm rab koob yog du, lub koob ntxig yog du, thiab tus neeg mob hnov mob tsawg.
2. Koob raj: zoo yooj, laser txiav ntawm qhov chaw txiav, du thiab tsis muaj burrs.
3. Connector: Lub connector yog kub-plated los txo cov teeb liab distortion, kom ruaj khov thiab siab raug ntawm lub teeb liab.
4. Kov: Los tiv thaiv plam tsim, nrog cov yas protrusions qhia txog kev hloov pauv ntawm rab koob, yooj yim siv.
