Conducted Electrical Weapon Drive-Stun Wounds

Abstract

Direct contact with the front of many handheld conducted electrical weapons (CEWs) is a common method of application. This method is sometimes referred to as a “touch stun” or “contact stun.” However, “drive stun” is the most widely accepted term for this type of application. This term is appropriate since the user “drives” the CEW into the recipient to ensure adequate contact. Metal surfaces on the front of the CEW or its cartridge serve as the requisite minimum two points of contact for conduction of electrical current. These points of contact are fixed and close enough that, in general, there is stimulation of peripheral sensory neurons but little stimulation of regional motor neurons. This results primarily in a painful stimulus and less incapacitation.

Because this method of contact involves pressure with fixed electrode points into a typically moving target, it results in a unique type of wound pattern. This pattern has multiple variations depending on many factors including angles of contact, interference with clothing, and type of CEW used. It is important for clinicians, investigators, and legal authorities to understand these factors and the appearance of these wounds. This will help to avoid confusion and uncertainty. This chapter will aid the reader in improved recognition and understanding of these wounds.
