What is a concussion?


A concussion is a traumatic brain injury (TBI), resulting from a hit to the head which temporarily changes brain function. Most concussions occur due to direct impact to the head. However, impact to the body (ie: body checks, falls, cross checks, or tackles) which cause the brain to move quickly within the scull, may also attribute to TBIs.

 

What are the impacts of a concussion?


Any trauma to the brain should be considered serious!

“Subconcussive level impacts can lead to significant neurological alterations, especially if the blows are repetitive” 1

Symptoms of concussions are not the same for everyone and vary based on the severity of the brain injury. Concussion suffers can exhibit a variety of physical, cognitive, and emotional symptoms. Those who have experienced a concussion are more likely to suffer another, especially if the injury occurs before the first concussion has had time to heal. TBIs can also cause epilepsy and increase the risk for conditions such as Alzheimer’s disease, Parkinson’s disease, Chronic Traumatic Encephalopathy (CTE), and other brain disorders that become more prevalent with age. 2 Repeated mild TBIs occurring over an extended period of time (ie: months,years) can result in cumulative neurological and cognitive deficits. Repeated mild TBIs occurring within a short period of time (ie: hours, days or weeks) can be catastrophic or fatal. 3

 

What is a Shockbox?

 

Shockbox

Shockbox helmet sensors were developed as a front line assessment device to warn parents, athletic trainers and coaches when a player impact should be assessed for concussion.

 

How does Shockbox work?

 

When attached to a helmet, Shockbox can assess the magnitude and direction of a hit that may result in a concussion.* Shockbox is designed to alert at a threshold of 50g (peak G linear acceleration) to the head by using algorithms to calculate helmet and head acceleration. Based on research from Gwin et al*, it was seen that 86% of impacts in football fall below the 50 g threshold. There is also a growing body of research indicating that concussions predominantly fall in a range between 70 – 100 g (Broglio et al**). 

 

 

 *No helmet sensor can accurately determine that a blow to the head is concussive

 

 

Shockbox Research Studies


Impakt Protective has been conducting clinical research and pilot use studies in hockey and football since 2011 in order to validate the efficiency of the helmet sensors technology as well as develop the Shockbox products and software system.
