Ankle Dorsiflexion: Why is Ankle Dorsiflexion a metric on the AMI?

Image
  Ankle Dorsiflexion and the AMI   Our sales team is regularly asked: why is ankle dorsiflexion in the AMI ? To this, dorsaVi reply: why would you not look at the ankle? Our AMI uses a criterion-based approach to measure the foot and ankle, the knee and the hip. The reason we prioritize looking at ankle DF is because we recognize that when we look at an athlete’s lower extremities, we are looking at a chain. The ankle is a key component of that the chain and if you remove that link, then it will be compensated for elsewhere (typically in the knee or hip).   Why is the ankle important?   If an athlete lacks dorsiflexion, for example on the left side, and then they perform a bilateral squat, they will shift their weight to the right side in order to get down to the required depth. When the athlete shifts to the right during their squat, the ankle dorsiflexion on the right leg is going to be increased and the dorsiflexion on the left side will be less. If the athlete has

Great Article from Sports Ed TV: Kinesiophobia - are you addressing it in your athletes?

                 KINESIOPHOBIA - an article byTrent Nessler  If you are not addressing Kinesiophobia in your athletes, then you are missing an important part of their rehab.This is a great article by Trent Nessler that discusses Kinesiophobia. Read the article here:  Kinesiophobia Article Recent research shows that if athletes demonstrate high levels of kinesiophobia (as measured on the TSK-11) they are 13 times more likely to reinjure upon return to sport (Paterno et al Sport Health 18).  We also know that these same fears after an injury are associated with altered movements.  Noehren et al Ortho J Sport Med 18 demonstrated that athletes who had high levels of kinesiophobia also unloaded the involved side during a vertical drop jump test.  This means, one side is bearing more brunt of the work versus the opposite side.  The side they are shifting away from will never develop strength comparable to the other side unless this is corrected.   Assessing your athletes with a battery of ob

Interesting Research Article: Effects of Pubertal Maturation on ACL Forces During a Landing Task in Females

  Effects of Pubertal Maturation on ACL Forces During a Landing Task in Females Nasseri et al: American Journal of Sports Medicine Sept 2021 Rates of anterior cruciate ligament (ACL) rupture in young people have increased by >70% over the past two decades. Adolescent and young adult females aged 15-19 years are at higher risk of ACL injury as compared with their prepubertal counterparts. On the basis of the Tanner classification system, 19 pre-, 19 early-/mid-, and 24 late-/postpubertal females performed a standardized drop-land-lateral jump while 3-dimensional body motion, ground-reaction forces, and surface electromyography data were acquired. The data were used in a validated computational model to estimate ACL loading.        Results: When compared with pre- and early-/midpubertal females, late-/postpubertal females had significantly higher ACL force. No differences were found between pre- and early-/midpubertal groups in ACL force or its contributors. Growth of ACL volume plate

Interesting Research Article: Bilateral Squatting Mechanics Are Associated With Landing Mechanics in Anterior Cruciate Ligament Reconstruction Patients

  Bilateral Squatting Mechanics Are Associated With Landing Mechanics in Anterior Cruciate Ligament Reconstruction Patients:  Peebles et al Am J Sport Med 21. This study assessed 41 patients who had undergone ACLR, performing 15 unweighted bilateral squats and 10 bilateral stop jumps. The movements were assessed using three dimensional kinematics measuring peak knee abduction angle, knee abduction/adduction range of motion, peak vertical ground-reaction force limb symmetry index (LSI), vertical ground-reaction force impulse LSI, and peak knee extension moment LSI during the descending phase of the squatting and landing tasks. Results: The peak vertical ground reaction force, the vertical ground reaction force impulse, and the peak knee extension movement were reduced in the surgical limb compared to the non- surgical limb during both the squatting and landing tasks. Conclusion: This study shows that ACLR athletes shift their weight off their involved leg (lateral shift) and t

Does Sport Specialization Increase Risk for Injury?

Image
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 Care Surgery, 2011 )

The dorsaVi AMI v. Competitors: How do the AMI wearable sensors compare to what is on the market?

  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 Nessler, PT, MPT, DPT, and co-founder of the AMI, answers t

10-41 Discuss How Their Athletes, Coaches, and Parents Have Responded To Using DorsaVi's AMI?

Patient Care and the AMI When deliberating whether dorsaVi’s Athletic Movement Module (AMI) is a fit for their clinic, many potential customers ask our sales team about the impact the test and the test results have on the athlete:  can patients interpret and understand the results of their AMI test?  How easy is it for the clinician to explain the results to their athlete, or even to the athlete’s parents? And what are their feelings about the AMI tests?  To answer this question, we thought it best to ask one of our existing customers: Courtney Green, physical therapist, and Jeff Hannah, Conditioning Coach, from 10-41 Strength and Physical Therapy. 10-41 Strength and Physical Therapy is the first facility in Alabama to partner strength coaches with a full-time physical therapist and have been reaping the benefits of AMI, using and avidly enjoying the technology In a few quick and easy video clips down below , you can listen to Green and Hannah  explain the positive outcome and customer
