How many joints must be controlled for a joint lock to be effective?

For a joint lock to be effective, it must control two or more joints. This is because controlling multiple joints ensures greater leverage and stability when applying the technique. When more than one joint is engaged, it increases the effectiveness of the lock, making it more difficult for the opponent to escape or resist the maneuver.

In many joint locks, the alignment and movement of connected joints are crucial. For example, controlling the elbow and wrist simultaneously allows for a more secure hold and greater control over the opponent’s movements. When only one joint is controlled, it may not provide sufficient leverage or security, allowing the individual to break free or counter the technique. Thus, the requirement of controlling two or more joints is a fundamental principle in defensive tactics that enhances the effectiveness of joint locks.
