Explain how a carotid choke works.

[Coach Josh]

Good find UK. So why isn't this present in more Judoka worldwide?

What is a lesion? Isn't it a tear or bleed? How would lack of blood flow cause that?

What pain? What nerve? What type of shock?

Southpaw sometimes people pass out instantly from a choke and sometimes it takes a few seconds. This is not conjecture but a fact. So obviously they do work faster at times.

Pressure in carotid sinus baroreceptors. Not a very recent discovery. Pressure in this area has been used to lower blood pressure in clinical environments.

Can't answer the questions as my arts department login doesn't get me onto the medical and science type websites. Maybe someone doing biology or a science degree can get access I'll try and find a biology friend.

However, why aren't more Judoka identified, perhaps because they aren't being studied or examined for it. Or because you need to be put out regularly rather than just tapped. From the adbstract, which has very little info, it seems they only noticed the lesion after a brain scan specifically looking for damage and psychometric testing revealed some memory problems.

Its likely that a normal and otherwise healthy person would never go for a brain scan or that a lesion might be missed. Also it depends on the level of memory problems and if you have to be exposed to shimewaza for a long period i.e 20/30 years. Then it may coincide with the natural memory problems that occur with ageing and so be dismissed by people as just naturally getting more forgetful as you grow older and thus never get checked out with an eye towards looking for causes of memory problems from brain damage.

Explain more please an in laymans terms.

Clinical environment sends up a red flag for me since the parameters are of 2 people in active physical exertion.

I'll try

Massage in this area is used to detect hypersensivity in the pressure receptors (for diagnosis) and as a "first aid" in cases of very high blood pressure.

What we have here is not a typical vasovagal syncope but an induced "carotid sinus syncope" which has different symptoms.

OK but it in terms that a 5th grader can understand

My Taber's Medical gives the definition of a lesion as: 1"a circumscribed area of pathologically altered tissue" 2"an injury or wound" .

The definition goes on to list specific conditions (blebs, bullae pustules....)

I found this definition interesting because in oncology we use the term lesion to describe a cancerous tumor, I had no idea the term was so general.

Press here-> -> guy nervous system gets confused -> guy passes out.

Can you download the pdf and attach it in a post so we can have a read of it, please?

DCS every time I press there someone will pass out?
