Nomenclature in ElectroAcupuncture and others

 Hello Friends,

I have some doubts in Nomeclature in E.A. 

First:

• the active pole (the site that you feel the sensation) is the negative (-) called catode, normally the black one.
• the passive pole (that there is no sensation) is the positive (+) called anode, normally the red one.

Second:  

• the direction of the electric current is the some of the energy flow.
• It goes from the (+), anode, passive to the (-),catore, active. To tonify you you that, and sedate the opposite.

Third:

• In the acute pain site you use the pole (-), chronic pole (+).
• Sedation point pole (+) and tonification point pole (-)

Fourth:

Low frequency ( < 40hz) acute pain and chronic High frequency (> 100hz). How you characterized acute and chronic ? Just by the time or it take account the exacerbation of the pain ?

}Thanks Again Leonardo
