The Q-Collar is a lightweight neck band that applies gentle pressure to the sides of your neck to slightly increase blood volume inside the skull, which helps reduce how much the brain “sloshes” around during impacts.

What the Q-Collar Is

  • A flexible horseshoe-shaped band worn low around the neck, behind and to the sides of the throat.
  • Cleared by the FDA as a class II medical device to be used alongside helmets and other protective gear, not as a replacement.
  • Marketed mainly to athletes in contact sports (football, hockey, soccer, lacrosse) and to soldiers exposed to repeated head impacts.

How It Works (Simple Version)

  • The collar squeezes lightly over the jugular veins, similar pressure to a snug necktie.
  • This partial compression slows blood leaving the brain, so a bit more blood stays in the skull, increasing intracranial blood volume slightly.
  • With more blood in the vessels, the brain fits more tightly in the skull, so it moves less when the head is hit, lowering the mechanical forces that can damage brain tissue.

The “Brain Slosh” Idea

  • In a hit or sudden stop, the brain can move and twist inside the skull, a phenomenon often called “slosh.”
  • That internal motion, not just the blow to the skull, contributes to concussions and sub-concussive injury.
  • The Q-Collar aims to act like a seatbelt for the brain: less empty space, less slosh, less shear stress on brain tissue during impact.

What It’s Made Of and How It Feels

  • Built from a silicone-urethane outer shell around a specially engineered spring that provides consistent, low-level compressive force.
  • Designed to target the sternocleidomastoid area (side of the neck) to press the internal jugular veins without blocking the airway or arteries.
  • Users often describe feeling only light pressure after proper fitting, and it is meant to be worn during play or training, then removed.

Evidence, Limits, and Safety Notes

  • Multiple independent studies, including imaging studies in athletes, suggest reduced changes in brain structure or function when athletes wore the Q-Collar versus those who did not, after a season of impacts.
  • However, experts note it does not guarantee prevention of concussion or long-term brain disease; it is an add-on layer of protection, and research is still evolving.
  • It should be fitted and used according to instructions (and any medical guidance) since it works by altering venous blood flow and intracranial blood volume, which may not be appropriate for everyone (for example, some vascular or cardiac conditions).
