Definitions for "Armlock"
to apply pressure to a joint (usually the elbow) against its natural direction.
The legitimate application of pressure to an opponent's elbow joint to gain a submission.
An armlock is a single or double joint lock which hyperextends, hyperflexes or hyperrotates the elbow joint and/or shoulder joint. An armlock which hyperflexes or hyperrotates the shoulder joint is referred to as a shoulder lock, and an armlock which hyperextends the elbow joint is called an armbar. Depending on the joint flexibility and integrity of a person, armlocks which hyperrotate the shoulder joint can also hyperrotate the elbow joint, and vice versa.
