VI Perform AMI
Athletic Movement Index™ (AMI™)
The Athletic Movement Index or AMI™ was developed by Dr. Trent Nessler with over 20 years of clinical practice, research and development. Frustrated with current methods available, Dr. Nessler had a desire to find a way to accurately assess and treat his athletes following lower extremity injuries. The AMI™ is a tool which utilizes the latest in movement science to accurately and reliably identify movement patterns that put athletes at risk for injury and performance issues. The AMI™ is a sequence of movements that progresses from bilateral and core movements to progressively more difficult single limb plyometric activities. Through this sequence of movements, the evaluator is able to determine what components of the kinetic chain are leading to the overall pathological movement patterns in a sport that put athletes at risk for injury or decreased athletic performance. As an athletic evaluation, this is designed to assess how an athlete looks when they have been on the field for some time and not how they look when they step on the field. As such, at the conclusion of this test, the athlete will have completed 83 reps and 3 minutes of core timed core testing.
DorsaVi ViPerform AMI™
In 2016, Dr. Nessler and DorsaVi (Australian based wearable sensor technology company) launched the ViPerform AMI™. By leveraging the DorsaVi wearable and wireless movement sensor technology with the Athletic Movement Index™, we are able to track and measure with lab quality data how elite athletes move in real-time across a variety of sports and movements. The ViPerform AMI™ system consists of wearable motion sensors that record data at 200 frames per second, intuitive software with sophisticated algorithms that turn robust data into easy-to-read human movement data and meaningful actionable results about how athletes are moving. ViPerform AMI™ assesses core movement and lower limb movement within 3% of a Vicon (motion capture lab) system. In addition, the evaluator will be able see limb symmetry index (LSI or variance between right and left limb) on a variety of movement tasks based on stability during single limb tasks (control of frontal plane motion and speed of valgus).
At the conclusion of the test, the evaluator is provided with a comprehensive, easily interpreted report that summarizes over 1000+ data points that are collected during the assessment. From this, you can easily determine most effective correctives as well as their effectiveness on future assessments.

RTPlay
One of the most difficult decisions to make in sports medicine is when is an athlete ready to return to play (RTPlay). With that decision comes a high degree of responsibility and liability for the medical professional. According to the research, not only are athletes who RTPlay susceptible to reinjury (28% reinjure, Rousseau et al AJSM 19′) but their future performance is negatively impacted for up to 2 years (Mai et al AJSM 17′). This is the result of multiple factors including: there is no standard RTPlay assessment, most of the standard assessments are too subjective in nature (assessed via visual interpretation), do not quantify biomechanical factors that put athletes at risk (Wren et al JOSPT 18′) and biomechanical risk factors are not properly addressed in rehab (King et al AJSM 19′). Additionally, with movement assessments, the question has also remained on whether or not what you see in the movement assessment actually correlates to what you see on the field.
The ViPerform AMI™ RTPlay blends the latest in movement science to help medical professional make an more informed decision. With a combination of psychological data, demographic data, a 3D comprehensive movement assessment (AMI™) and a 3D on the field maximum acceleration/deacceleration test, we are able to provide the most comprehensive, completely objective approach to RTPlay. Stop guessing if they are ready to RTPlay…Know with ViPerform AMI™ RTPlay!

Frequently asked questions
Once a user becomes proficient (4-6 assessments), the full “ViPerform AMI assessment” will only take 15 minutes per athlete. This does not include the set up time or entering the athlete information. The system does allow you to import athlete data prior to testing for when doing mass physicals.
In 2018, we performed over 2000 pre-participation physicals using the ViPerform AMI at the high school, college and professional level. On the average, with proficient users, we can process 110 athletes per day.
For CPT coding, you should always check with your compliance department. However, the ViPerform AMI meets all the criteria for billing 97750 (physical performance test). Typically with set up, performing the test and explaining the results to the athlete this results in 3-4 units of 97750. If report is attached to your EMR note along with an explanation of the test, in states where 97750 is reimbursed, this will prevent denials.
For those going through rehab, you do not have to perform the whole test. We encourage you to use this throughout the rehab process. Typically, performance on first part of the test determines whether individuals are ready to progress to more aggressive activity.
The ViPerform AMI is currently being used by several organization (colleges/professional teams) for base line testing. This will give them something to compare to if an athlete suffers a lower kinetic chain injury or concussion. Our independent research is showing reductions in all lower kinetic chain injuries from the foot to the lower spine.
Research shows a strong correlation to concussion and knee/ACL injuries (Gilbert et al Sport Health 16′, McPherson et al AJSM 18′). Studies also show that improvement in dynamic single limb stability reduces risk for concussion (Johnston et al AJSM 19′). As a result, several teams and organizations use the ViPerform AMI for baseline to compare after a concussion as well as a part of the concussion rehab process.
The system can function independent of internet access and can be used remotely on the field or on the court. You will need some access to electric supply for the computer.
As with any wireless technology, you have to be aware of your surroundings. With the ViPerform AMI the sensors can be interrupted if you are doing assessments in a space that is located right next or above an MRI or if you are doing assessments in a stadium with stadium quality WiFi (usually only in high DI schools or professional teams).
With over 13,000+ assessments performed, we have been able to determine some recommendations for RTPlay. This is based on magnitude of motion in the frontal plane, speed motion in the frontal plane, overall LSI, psychological scores and sprint data. As always, RTPlay is a clinical decision made by the health care professional, the ViPerform AMI RTPlay is only intended to provide more objective information to help guide that decision.
Anyone can purchase the ViPerform AMI. As a part of this purchase, you are provided a 4 hour training on how to accurately perform the test and provided some basics in interpretation of the data. The AMI Specialist takes it to the next level.

BFR - Blood Flow Restriction
Blood flow restriction training has been around since the late 60s. Back in those days, this was most commonly used in bodybuilders. Today however, there has been a resurgence and increasing acceptance of this training methodology in the area of rehabilitation and sports medicine. With this resurgence has come a lot of misconception about what BFR is, what it is not and how it can not be used.
This online course seeks to provide participants with the latest research in the area of BFR. Leveraging this research to know what protocols are research based and safely implemented. How BRF should be implemented and differences in pneumatic and non-pneumatic BFR devices.
This course is NOT specific to a particular blood flow restriction device but does provide some basic science behind BFR irrelevant of which device is used. In this course we will dive into the misconceptions of BFR, the biochemistry and physiology behind the use of BFR and how BFR can be used in populations other than just athletic individuals.
