3D Motion Analysis - ViMove+ AMI

The AMI is the brainchild of Dr. Trent Nessler.  Developed out of a frustration after seeing a high volume of young athletes with ACL injuries, he was set on a mission to solve the unsolvable problem. After receiving his doctorate with a focus in biomechanics and motor learning, Dr. Nessler set out on the journey of trying to accurately assess athletes for movements we know impact injury risk and performance.

A self professed sports biomechanist, Dr. Nessler is one of the leading experts in assessing athletic movement.  After 18 years of research and development, Dr. Nessler partnered with DorsaVi to launch, what is known today as, the ViMove+ AMI.  The ViMove+ AMI uses 4 wearable sensors placed on the body to record how you move during a prescribed and standardized sequence of movements.  The sensors capture movement within 2% of the gold standard and over 3500 data points per assessment.   Now available in 5 countries and used in professional sports and elite tactical forces, Dr. Nessler’s system has been used to assess 90,000 sport and tactical athletes globally.  Today, this represents the largest objective movement database in the world with over 320M data points related to human movement.

The ViMove+ AMI is designed to assess core stability, symmetry in loading during bilateral tasks and limb and core stability during single limb testing.  The ViMove+ AMI consist of:

  • 1 minute plank
  • Squats
  • 1 minute right and left side plank
  • Single leg squats
  • Single leg hops
  • Single leg hop plant (multi-directional hop)
  • Ankle lunge test
Example of Single Leg Squat Reporting

The results of this test will provide:

  • Overall movement score
  • AMI Rating
  • Loss of balance (LOB) and LOB LSI
  • Absolute LSI – based on LQI scores on each limb during performance of multiple tasks
  • LSI – limb symmetry index – compares performance on the right side versus left on each rep on each task
  • LQI – limb quality index – is a measure of quality of movement during each rep of each task and is based on dynamic valgus, speed of valgus pelvic, degree of pelvic motion, and depth of motion.

The AMI provides clinicians with the objective measure and guidance on where your specific weaknesses, tightnesses and instability issues are.  This information guides the development of the most effective program to address.  When this is improved, there is a direct impact on the results of the test, mitigation of injury risk and improvement in athletic performance.  Since its development, Dr. Nessler has used this data, the information gained from and over a decade of research to develop the most effective treatment strategies for improving human movement available.  The technologies, treatment protocols, exercise progressions/equipment, and nutritional recommendations provided by The Athlete Lab have all been found, through measurement of objective data and outcome measures, to provide the most effective impact on human movement and results on the AMI.

Dr. Nessler has used this information to develop educational certifications, develop commercial products and services and spoken at national sports medicine conferences globally on what he is learning and how he develops programs to improve.   Through a partnership with Northeast Seminars, he developed The AMI Certification Course which certifies clinicians in use, clinical interpretation and how to develop programming to impact.  In Dr. Nessler’s book, How To Build A Badass Firefighter, he applies these same principles to the tactical athlete (police, fire, SWAT, Special Forces, etc).
