Simple and Affordable is Hard

Applying force to muscles in order to determine their structural integrity has its roots in the muscle testing techniques from physiotherapy. A muscle is put into a position of contraction that isolates it’s function and manual pressure is applied to evaluate the strength and function of that particular muscle. This is a very specific force tested on a isolated target.

This concept was expanded in 1988 by Lois Klatt, PhD, who developed a simple jump test that adds a sudden load throughout many muscular chains in the body. Depending on how the individual reacts, you can identify the weakest muscle in the kinetic chain. This is a general force applied to reveal a specific weakness.

The RAM Technology compares the movement velocity of the thoracic spine to the amplitude, velocity, and rotation that occurs in the chin and forehead motion. The total G forces along with the magnitude of the head tilt and speed that occurs tells us:

  1. A low velocity impact combined with our sensor technology allows a microscopic view of the mechanics created during simulated contact. The rad/s (range of angular velocity, ω) combined with the magnitude of acceleration over time (in milliseconds) tells us exactly how the athlete will respond when hit during a game.
  2. How extensor and flexor musculature affect a broad spectrum of strength qualities that allow the deceleration of head and neck mass.
  3. The milliseconds in which the head tilt is reversed tells us the reflex speed and is a predictor of trauma to the deep cervical musculature and highly correlated with their ability to stabilize higher loads of impact.
  4. Whether they have a pre-existing musculoskeletal dysfunction that puts them at greater risk to secondary concussion syndrome enabling us to identify and implement proactive rehab strategies.
  5. The ideal ratios required to optimize the training effect, which govern exercise selection, training protocols, and rehab strategies.


The paper by Nazarahari, M., Arthur, J. & Rouhani, H. Titled A Novel Testing Device to Assess the Effect of Neck Strength on Risk of Concussion has been published in the Annals of Biomedical Engineering. This journal is historically a prestigious archival journal in biomedical engineering. The U of A article went through 3 rounds of critical peer-review and can be cited as a proof of the validity of the RAM device (in the scope and to the extent discussed in the article).

Specifically the U of A team studied the contribution of individual neck muscles on the reduction of angular head acceleration in simulated sports contact. The goal was to identify the optimal ratio of strength between muscle groups that strength training should strive to achieve which reduces angular acceleration in common scenarios of impact.

A Novel Concussion Active Prevention Testing Device for Neck Strength Evaluation During Sub-concussive Impacts” paper was presented at The Canadian Society for Mechanical Engineering (CSME) International Congress 2018 in Toronto, ON, Canada. The RAM technology was clinically validated by the CSME.

CAP is working with Auckland University of Technology to analyze our CAP data from the kinematic response to impulsive loading. By analyzing the relationship between strength performance and the movements of the head we can predict a strategy and protective levels of strength that the athlete can develop to reduce susceptibility to concussions.
