This method was developed over the years since I worked at the Beth Israel Hospital in Boston way back in 1992! Being a place of care, regardless of whether or not the patient was under the influence or drugs, alcohol or just an emotionally disturbed person, (EDP), they were there for help. As security officers, like cops, we were held to a higher standard. Non-violent methods of restraints were required and what was being instructed was not quite doing the job. With a basic background in Hapkido at that time, I began creating techniques based on my knowledge of joint manipulation to safeguard both the patient and the employee. This is one of my go-to's still to date.
Enjoy and stay safe. Sharing is caring, if you do.
