The Carotid Restraint Training Institute is a division of Boydd Products, Inc. and was developed in 2013 to create subject matter experts at the agency level. The Law Enforcement Vascular Neck Restraint (e.g. Carotid Restraint) is a bilateral vascular restraint and is NOT a respiratory "choke hold." The technique protects the vulnerable front structures of the neck including the subject's airway. As with most police use-of-force techniques, associated risks always remain a factor. This program is based on the latest research and studies on police neck restraints by Dr. Jamie Mitchell. Ph.D. (2011), Dr. John Pi, M.D. (2010), and research conducted by the Canadian Police Research Centre with Dr. Christine Hall, M.D. (2007). A thorough and effective training program is essential for proper application of bilateral vascular restraint techniques, strong litigation defense, and protection against claims of deliberate indifference in police training or policy.

This program is designed to meet or exceed current law enforcement and state training standards. Many states or training presenters simply integrate bilateral vascular restraint training as part of a larger or broader control tactics instructor program where multiple tactics and control techniques are learned. Generally, only few hours are spent on the subject of neck restraints before the curriculum moves to the next block of instruction. At CRTI we prepare your subject matter experts by specifically focusing on the Vascular Neck Restraint and provide in-depth exposure to this dynamic and often misunderstood force option. Since January of 2013, CRTI has presented this course to over 800 law enforcement trainers from more than 220 agencies nationwide (see attending agencies button below).
