Fixed Versus Mobile

Fixed Versus Mobile

Part of activating muscle is having it.

describe the imageThe Pashby Sports Safety Award is an award presented in Canada to recognize and honor people who make sports and recreational activities safer from catastrophic injuries, which typically involve the eyes, spine or brain.  Dr. Karen Johnston MD, PHD was given the Safety Award for her outstanding work to prevent injuries, most specifically concussions.

She is also Director of the Concussion Program at the McGill Sports Medicine Clinic.

Dr. Karen Johnston says that, “The force required to concuss a fixed head is almost twice that required to concuss a mobile head”.

Mouthguard companies understand that by activating head and neck muscles at the time of impact rotation will be decreased, which will lead to less harmful movement of the brain inside the skull.

By being able to clench down hard on a mouthguard activates the head and neck muscles and stabilizes the head.

describe the imageRalph Cornwell is taking this one step further,  building bigger stronger cylinders by developing the musculature around the head, neck and thoracic spine. The developed muscles dissipate more force and ‘clenching’ on the mouthguard with a stronger head, neck and jaw augments the value of dissipation by stabilizing movement.  This further reduces the subconcussive forces involved in causing a concussion.

A Virginia Tech doctoral canidate Ralph Cornwell, is doing research at Elon University in North Carolina.

He is not only building necks, but a mathmatical model of force dissapation.

Build head, neck and trap muscle to dissipate force and fix the head to lower concussive forces and Get Strong.

  1. Great Post Ralph. The muscles around the neck as well as the neck are very often ignored in designing programs. Although, they are a vital part of injury prevention. Thanks for sharing.


  2. Ralph, it’s exciting to hear about your doctoral research and dissertation on designing protective equipment to prevent concussion in sports. I commend you on making that your focus because the sports industry needs needs to know more options in preventing brain injuries to players of all ages.

    Keep me posted as I would love to blog about your research and results on my web site:—maximum-sentence-for-eugene-hickman/
    We need advocates like you. Best of Luck!
