The Science

Join Dr. Theo Versteegh to explore the impact of higher dynamic neck strength on reduced concussion risk. In this video, Theo dives into a revolutionary concept in concussion mitigation: Rate of Force Development (RFD). Learn how increasing mutli-planar (all 3 planes of motion) RFD in the neck enables an active approach to concussion risk reduction.

  1. EMG (Electromyography – a way to measure muscle activity) changes before and after training on the TopSpin360 in healthy adults.
  2. Effects of training on the TopSpin360 on static and dynamic neck strength, neck strength balance and 40 yard dash performance in female varsity athletes (women’s soccer and rugby). Link
  3. Examining the use of the TopSpin360 for the treatment and rehabilitation of sport related concussion in adolescents and young adults with prolonged symptoms (>28 days) and cervicogenic symptoms (neck pain). Link.
  1. 20 university level high-concussion risk football players (starters from high risk positions) trained on the TopSpin360 during the pre-season, ZERO experienced a concussion the following season (given risk profile, expected number was 3-5 concussions)
  2. University women’s volleyball team went from 7 concussions in 2018 to ZERO in 2019 after implementing TopSpin360 training during the off-season
  3. University women’s soccer team went from an average of 3-8 concussions per year to ZERO following implementation of TopSpin360 training during the off-season

For every one pound increase in neck strength, odds of concussion decrease by 5%. We conclude that identifying differences in overall neck strength may be useful in developing a screening tool to determine risk of concussion.

Neuromuscular training designed to enhance cervical muscle dynamic responses may be a more suitable and effective approach than strength training to reduce the odds of sustaining high-magnitude head impacts among football athletes.

In conclusion, the results of this study suggest that greater neck strength accentuates the head’s dynamic response to external forces. These relationships hold true in all planes of head motion and across the age spectrum in athletes of both sexes.
