Studies have consistently shown that ​approximately 60-80% of confrontations between law enforcement officers and suspects occur on the ground. This may be due to an ​officer taking a suspect to the ground, a suspect taking an officer to the ground, or simply due to loss of balance and control by either ​the officer or the suspect.

The majority of​ individuals suffering from extreme psychosis, who are under the influence of psychotropic drugs, or who demonstrate a high tolerance for pain are usually brought under control on the ground after a prolonged confrontation with officers. These individuals are very difficult to control and are usually subdued after multiple force options have been utilized or exhausted, or superior manpower finally prevails.

The Carotid Restraint Training Institute's methodology concentrates on proper and safe application of a bilateral vascular restraint technique in order to gain quick compliance and minimize risk during these intense struggles. Bilateral vascular restraint techniques can be started or applied while standing, however, the CRTI method focuses on ground application where the law enforcement officer utilizes close body control to effectively limit the subject's mobility and ability to alter the placement of the hold.

This is intended to:


​​1) Negate the risk of officer injury from temporarily bearing the weight of an unconscious or conscious person from the standing position to the ground.

(2) Negate the risk of airway or cervical injury to the subject due

to potential torsional movements or from a takedown involving

a neck hold.

(3) Negate the risk of secondary injuries if the subject were to be

unintentionally dropped or the officer loses balance during a dynamic struggle.

   Although a static and sterile training environment has its benefits when it comes to initially learning proper technique, CRTI promotes a progressive training system that will develop skills ranging from static learning to performing these skills under stressful conditions that the officers will inevitably face in the field. The dynamic motion of a real struggle routinely causes challenges for officers attempting to safely apply or maintain correct positioning of bilateral vascular restraint techniques. This training system will better prepare students through progressive repetition and continual assessment to ensure proper arm placement and positioning is maintained under stress, resistance and motion.

The Vascular Restraint objective is to quickly restrain and gain safe control of a violent or potentially violent subject.

The goals include:

​(1) Application from a ground position

(2) Ensure proper alignment prior to application

(3) Seek voluntary compliance or render the subject unconscious

(4) Safely place the subject in a position to allow for quick handcuffing

(5) Place the subject in a recovery position and assess vital signs

(6) Obtain medical clearance
