Let's examine various arm pressure points.
The arm holds a variety of usable pressure points for women's self defense.
The inside of the elbow joint is a good striking point for self defense purposes.
A blow here will cause pain and cause the joint to bend. If enough force is used it could also cause a numbing effect, temporarily incapacitating the arm.
There's no need to come too close to deliver such a blow. A knife hand or hammer fist would be effective as well as a well aimed, quickly executed kick.
The outside of the elbow joint
is of limited practical value. If the arm is bent a blow here could
cause a numbing effect, but one risks self injury from the bony point.
On the other hand if the arm is straight a blow here could cause
hyper extension, injuring cartilage and incapacitating the arm.
The forearm mound on most
people is very sensitive to pain, there fore is a good arm pressure point. If you extend your arm with your thumb
up, the mound is just beyond your elbow, towards your hand. A forceful
blow here- say a knife hand- will cause considerable pain, possibly
numbness and can partially incapacitate the arm temporarily.
A wrist strike would primarily
be used as a deflection technique. If an attacker were trying to grab
you could strike the wrist with a knife hand or hammer fist deflecting
the attempt. A heavy enough blow could cause a bone bruise.
The back of the hand provides sensitive areas between the bones and tendons. If someone grabs you from behind you could use your knuckles to grind in the back of their hand. This technique works well no matter what the size of the potential victim.
Scrape your knuckles against the back of his hand.
