NCT03017937

Brief Summary

Clinical trials have suggested that this device is effective in mitigating changes in brain structure and function in athlete populations. The purpose of the current study is to measure the response of the jugular vein to various pressures applied by a generic compression device across various ages and gender. The relative jugular vein response will be measured using ultrasound.

Outcome Measures

Primary Outcomes (1)

  • Neck Collar Size

    measurement of the neck collar size at each pressure level

    1 hour

Study Arms (1)

Q- collar

EXPERIMENTAL

All subjects will wear 3 sizes of the q-collar and ultrasound images of the jugular vein will be measured with each collar. Also, each subject will wear a pressure collar and ultrasound images of the jugular vein will be captured at each pressure point (0.1-0.5)

Device: Q-collar
