dorsaVi Athletic Movement Index (AMI)

Symmetry in Triple Hop Distance Hides Asymmetries in Knee Function After ACL Reconstruction in Athletes at Return to Sports This research article, from The American Journal of Sports Medicine , evaluates the lower limb function of athletes after ACL reconstructive surgery and aims to question the effectiveness of the triple hop for distance test on athletes who have passed the return to sport (RTS) assessments. This study was done in a controlled laboratory study and conducted on 47 male athletes:  24 athletes had undergone ACLR and were cleared to RTS  The criteria for RTS was one of the following: (1) clearance by the surgeon and physical therapist (2) completion of a sports-specific on-field rehabilitation program (3) limb symmetry strength index <90% after quadriceps strength and hop battery tests.  23 athletes were healthy controls during the triple hop test.  From here, lower limb and trunk kinematics were calculated and evaluated using mixed linear models. ...

Why Did DorsaVi Create the AMI? On this blog, we have discussed: what the AMI is capable of, case studies and reviews from clients about this wearable sensor technology. However, we have yet to discuss how the AMI came to be created. Our Marketing & Sales team had the opportunity to sit down and talk with Dr. Trent Nessler, PT, MPT, DPT and the co-founder of the AMI to ask exactly "Why the AMI was built?" As a Physical Therapist, Doctor Trent Nessler was witnessing movement patterns detrimental to an athlete's movement, even after they had completed rehab. Interested in reducing this risk, he set about trying to find a way to better assess an athlete's recovery.  Watch the quick clip below to hear how Doctor Trent Nessler came to create the AMI: For more information on the AMI, check out some of our other blog posts:  Why Have These Tests Been Specifically Selected For the AMI Assessment?

Sport Specialization and the AMI Studies have shown that children who participate in sport have an improved quality of life. They are less likely to smoke or to be truant at school and are more likely to maintain good grades. With over 7.8 million kids participating in interscholastic sports each year, sports injuries are inevitable, and dorsaVi designed the Athletic Movement Index (AMI) with the goal to minimize that risk of injury where possible.  DorsaVi’s interest lies predominantly with injury prevention for the lower extremity, specifically knee and ACL injury. Why do we hold a strong focus here?  Ingram et al ( American Journal of Sports Medicine, 2008 ) study showed that the most reported athletic injury between the ages of 15 and 25 is a knee injury.  Fernandez et al ( American Journal of Sports Medicine, 2007 ) showed lower extremity injuries account for 60-70% of all injuries in high school athlete populations.  Rechel et at ( Journal of Trauma and Acute C...

  The AMI v. Competitors At dorsaVi, we make wearable sensors. Our AMI module relies on easy to use wearable sensor technology: a clinician simply places these sensors on an athlete and conducts a series of seven tests to assess and record their movement. For our AMI module, wearable sensors are first placed on the low back in order to measure the movement of the lumbar spine. Whilst the sensors are on the low back, the athlete will complete:  One minute plank  20 full squats  One minute side plank (right and left)  The clinician will the switch the sensors from the low back to the tibia and continue the assessment with single limb testing:  Single leg squat  Single leg hop Single leg hop plant (hop forward, hop back, hop lateral, hop medial)  Ankle dorsiflexion  But, why do we rely on wearable technology when there is a vast range of other technologies out there? And   how does wearable technology compare with this?  Dr Trent ...

  We are very excited to share with you our new case study.  Here we discuss a return to play decision on a Collegiate Lacrosse player after an ACLR. By reading the case study posted below you can learn  how our AMI predicted injury potential in a Collegiate Lacrosse player during his Return to Play assessments.  More specifically, we will explain to you how the AMI Module and dorsaVi’s wearable sensor technology successfully detected movement fault on the athlete’s right side, eight months after ACL reconstruction surgery on his right knee. We walk you through the AMI module tests, data and results to explain how the module detected movement fault, why the AMI advised against return to play and the consequences of the athlete’s decision to continue to return to play.  We demonstrate how valuable the AMI module’s objective, actionable data is when assessing an athlete’s physical well-being: it is a crucial tool for injury prevention and creating safer return-to-...

  The AMI and The Tests The AMI module uses wearable sensor technology to create objective, actionable data and identify potential movement faults in patients. The AMI measures core stability, bilateral symmetry, single leg mechanics, and ankle dorsiflexion  through a mandatory set of seven research-based tests:  Plank test  Side plank test (left/right) Full squat test  Single leg squat  Single leg hop Single leg hop plant  Ankle lunge test But "why  have these tests been specifically selected for the AMI assessment?"  Time and time again, our dorsaVi sales team has been asked this question by countless interested customers.  To answer this question concisely , watch this quick five minute clip of Dr Trent Nessler , PT, MPT, DPT, and co-founder of the AMI, as he gives a detailed explanation as to how these seven tests came about, why they were selected and the importance of each when examining athletes well being.  

Poor Validity of Functional Performance Tests to Predict Knee Injury in Female Soccer Players With or Without Anterior Cruciate Ligament Reconstruction This research article, from the American Journal of Sports Medicine , investigates the poor validity of functional performance tests to predict knee injury in female soccer players with or without ACL reconstruction.  The study was conducted on a cohort of active female soccer players, 117 of which had ACL reconstructive surgery and 119 knee-healthy players:  At baseline, all players underwent tests to assess postural control (Star Excursion Balance Test), Hop performance (Single Leg Hop for Distance, Side Hop) and movement asymmetries in the lower limbs (Drop Vertical Jump, Tuck Jump). Then the predictive validity of the test cutoffs was assessed by identifying players who would sustain ACL injury or a severe traumatic knee injury. The study concludes that the validity of commonly used functional performance tests is...

  SportsEd TV and ACL Injuries in Volleyball SportsEd TV has uploaded two great articles discussing the increased risk for ACL injuries in volleyball players.  In the first article,  ACL Injuries in Volleyball  (click  here to read), SportsEdTV discuss certain factors which lead to an increase in injury to volleyball players, particularly in female athletes. The article also discusses how a coach could evaluate this risk in your players. The second article,  ACL Injuries in Volleyball – Part II  (click  here to read), continues from this article. This article investigates the question:      • Once you assess them, what do you do with that information?      • Is there a way to address this with training?      • By addressing this with training, will this mitigate their risk for injury? To tackle these questions, the article discusses a study documenting the positive outcome of dorsaVi wearable sensor t...

Effect of Anterior Cruciate Ligament Rupture on Physical Activity, Sports Participation, Patient-Reported Health Outcomes, and Physical Function in Young Female Athletes This research article, from the American Journal of Sports Medicine , looks at the effect of ACL reconstruction on future sports participation, patient reported outcomes, and physical function in female athletes.  The study was conducted on a cohort of 102 female athletes aged 15-23, 51 participants had undergone ACL reconstruction within the previous 1-2 years and 51 had no previous knee injury:  All participants were fitted with an accelerometer for 13 days that measured their Physical Activity.  The participants completed patient-reported health outcomes: Tegner activity level, Knee Injury and Osteoarthritis Outcome Score (KOOS), Knee Self-Efficacy Sale (K-SES), Anterior Cruciate Ligament Return to Sport After Injury scale (ACLRSI), Tampa Scale for Kinesiophobia (TSK-11).  Physical function test: ...

The TSK-11 and Patient Reported Outcome Measures DorsaVi’s Athletic Movement Index (AMI) is an amazing tool for clinicians to make Return to Play decisions, but we hope to encourage our customers to increase the validity of their Return to Play assessments by utilizing Patient Reported Outcomes Measures (PROMs), specifically the Tampa Scale Kinesophobia-11 (TSK-11). What is the TSK-11? And why is this PROM so important in ACL Return to Play assessments?  The TSK-11 is a questionnaire designed to assess an athlete’s mental status after sustaining a lower extremity injury; primarily used in the ACL sphere, it also has some application with foot, ankle and hip injuries (click  here to check out the TSK-11 questionnaire). Ultimately,  the TSK-11 assesses the athlete’s fear to bear weight and trust their previously injured limb . For example, if an athlete sustains an ACL injury and has reconstructive surgery on his right leg, they are likely fearful of cutting right and weig...

The AMI and Concussion  In a recent webinar with Dr Trent Nessler, PT, MPT, DPT and co-founder of the AMI (Athletic Movement Index) our dorsaVi team were keen to ask him about the significance of the AMI results in relation to a previous concussion and how concussion can relate to an athletes future health and movement.  Whilst investigating the relationship between concussion and movement, Dr Nessler started to see some interesting things as a pattern began to emerge:  Those who reported a previous concussion also reported more lower kinetic chain injuries. Those who had a previous history of concussion had poor motion and scored poorly on the AMI.  This is supported by the research: Those who had reported a concussion were 3 times more likely to suffer a lower kinetic injury. ( Frances Gilbert et al, Sports Health, 2016 )  This is why assessments, such as the dorsaVi Athletic Movement Index (AMI), are so important. Research indicates a relationship b...
