Some Kappō (活法), or Kassei-hō (活性法 - life activation method, i.e. resuscitation / revival) techniques from Ryōi Shintō-ryū Jūjutsu (良移心当流 柔術).These would have been taught together with Shime waza (絞技) chokes & strangles and also with Kenpō (拳法 - fist art), kyūsho-jutsu (急所術 - vital point method) techniques. I can remember being choked unconscious and revived by Shortt Sensei when I received by Shodan (初段 - 1st dan). Those were different times and I would not advise it now. However, it was an interesting experience.Another note of caution - for medico-legal reasons, be aware of and follow 'First Aid' protocols for any potential injury, or unconsciousness.
