There is a seminar or tournament or maybe both where an Isshinryu high graded karate-ka is going to teach what they are labeling "denshi's twenty for martial artist" that promotes a means to control and move an attacker from place to place as s supplement to the essence of karate or Isshinryu where the objective is to kick/punch to stop/destroy/maim an adversary (there words redacted a slight bit, not my words as I don't like to use words like destroy and/or maim, etc.).
It sounds a lot like the system called "Chin-na," a Chinese system of joint/pressure point manipulation, etc. or even the art of tuite but to this moment I had never heard of anything called "denshi's twenty." Anyone out there who travels by this post/blog can enlighten me it would be really cool.
I wondered at first if this was a Japanese/Okinawan word used to describe this persons favorite or what is perceived by him as the most effective, i.e. top twenty tuite/chin-na techniques. I looked up the word denshi and the meanings I ran across are:
Denshi [電子] which means electron; electronic; electronics; [電視] television.
Neither of these translations speaks to what is going on here unless the person intended it to mean a kind of shock to the body when these twenty techniques are applied. Some of the tuite/chin-na techniques could/can feel like a shocking electric type feeling of pain when applied but I may be stretching it a bit. Then again my theories or speculations may be way off on this one ergo why I ask for enlightenment from readers. Maybe it is used because of the stunned feeling you can experience here, i.e. similar to the stunned feeling when in receipt of a small electrical shock.
