Jugular Vein Compression Collar
Other Names
- Jugular Vein Compression Collar
- Jugular Vein Compression Device
- JVC Neck Collar
- Jugular compression collar
- Neck compression collar
- Q-Collar
- Cervical compression collar
- Brain protection collar
Introduction
- This page covers so-called jugular vein compression collars
- Note these are controversial and currently undergoing studies to determine clinical efficacy
History
- Gentle compression of internal jugular vein dates back to 1918 (need citation)
- Quenkenstedt showed that compression of the IJV caused a rise in spinal pressure
Basis for Use
- Objective: reduce the "slosh" of the brain in collision sports
- This is accomplished by compression of the internal jugular vein
Basis for using MRI markers
- This has been criticized
- Systematic review of 86 studies[1]
- Results suggested widespread but inconsistent differences in white matter diffusion metrics following mTBI/concussion
- MRI is "sensitive to a wide range of group differences in diffusion metrics, but that it currently lacks the specificity necessary for meaningful clinical application"
Evidence
Animal Studies
- Application of collar increased intracranial pressure (30%), intraocular pressure (31%)[2]
MRI Studies
- A study of 284 football athletes were separated into a collar and non-collar group[3]
- Application of collar provided mechanist response to diffusion, anisotropic properties on MRI
- A similar study was performed among 17 hockey players[4]
- They drew similar conclusions that "sport-related alterations in white matter microstructure were ameliorated by application of jugular compression during head impact exposure"
- Study among 75 soccer players[5]
- MRI is " sensitive to a wide range of group differences in diffusion metrics, but that it currently lacks the specificity necessary for meaningful clinical application"
EEG Studies
- One study looked at 23 SWAT personnel[6]
- Those who did wear the collar "demonstrated a possible amelioration of changes in the group that wore the JVC collar"
