What technique applies pressure to the back of the subject's hand during wrist control?

The transport wrist lock technique is designed to apply pressure to the back of the subject's hand while simultaneously gaining control over their wrist. This technique is often used in defensive tactics to safely manage and control a subject's movements without causing excessive harm. The application of pressure to the back of the hand helps to limit the subject's ability to resist or escape, allowing for easier transport or restraint.

The effectiveness of the transport wrist lock lies in its ability to maintain a balance between control and safety for both the subject and the officer. By keeping the focus on the wrist and hand, it allows for a significant level of control while minimizing the risk of injury that can occur if more aggressive techniques are employed.

Other techniques presented, while related to control and binding of limbs, differ in their primary focus or application. An arm lock generally encompasses a larger section of the arm, not just the wrist; a finger lock focuses specifically on manipulating and controlling the fingers; whereas a joint lock involves locking a joint in place, which can be more painful and restrictive. The uniqueness of the transport wrist lock lies in its specific focus on wrist control and pressure on the back of the hand.
