Clinicians' Corner
The clinicians’ corner will feature the previous month’s most-talked-about research article. We ask the authors for a clinical take-home message and ask a clinician to provide feedback on how they can use the research to improve their practice. This month we will feature two articles.

Herzog MM, Mack CD, Dreyer NA, Wikstrom EA, Padua DA, Kocher MS, DiFiori JP, Marshall SW. Ankle Sprains in the National Basketball Association, 2013-2014 Through 2016-2017. The American journal of sports medicine. 2019:036354651986467.
Herzog and colleagues collected data regarding ankle sprains in the National Basketball Association and provided the following take-home messages:
  • Based on the past 4 seasons, an NBA player has a 1 in 4 chance of sustaining an ankle sprain each season, and a 1 in 8 chance of sustaining an ankle sprain that results in missing a subsequent game.
  •  A majority of sprains were lateral (80%) and involved a contact mechanism (71%). However, high ankle sprains resulted in more NBA games and days missed due to injury than lateral or medial sprains.
  • Among players with a history of ankle sprain in the past year, the rate of ankle sprain in games was higher compared to those without a history in the past year.
  • More research on basketball-specific injury prevention strategies for reducing the incidence of ankle sprain and integrating injury prevention programs into the management of initial sprains may be beneficial.
 Clinical Opinion
Dr. Quinton Sawyer, the Associate Head Athletic Trainer for the Charlotte Hornets, provides insight into the findings of Herzog and colleagues’ NBA database search. His approach to managing ankle injuries, or any injury among his elite athletes, is an individualized one. He does not like to make generalizations about any injury he treats and notes “anytime an elite athlete has an injury or illness, their performance will likely be affected.” While ankle sprains have a 1 in 8 chance of causing a player to miss a game, Dr. Sawyer views his job as a healthcare provider is “to ensure that their performance can still be effective for them to perform their jobs without additional risk of injury.” Even though contact ankle sprains were highly prevalent in the NBA, these are almost impossible to prevent, yet not every contact mechanism results in an injury. When asked about his prevention strategies for contact injuries, Dr. Sawyers explains “people who have a more robust capacity for movement have been shown to have a higher resiliency to injury.” So, his efforts are focused on protecting patients against unpredictable and unpreventable contact injuries by incorporating movement strategies into everyday practice and training. His goal: “increase the patients’ movement library available to them on the court.” Further, he was not surprised that high ankle sprains caused more missed games among professional athletes and he views these are a completely different injury than a lateral ankle sprain. The differences in injury mechanism and structures involved with high ankle sprains do not surprise Dr. Sawyer that they have different recovery times.
According to his individualized treatment philosophies, Dr. Sawyer doesn’t have “hard and fast rules” when designing rehabilitation protocols. Rather, he uses “education and communication to help develop a plan with each patient as a member of the team.” He stated repeatedly the importance of treating the whole body in his elite athletes and the ability of athletes to “withstand the rigors of athletic participation without injuries” is reliant on their ability to “incorporate movements from different body segments” in a unified and coordinated manner.

Our second featured article this month is:
Grooms DR, Diekfuss JA, Ellis JD, Yuan W, Dudley J, Foss KDB, Thomas S, Altaye M, Haas L, Williams B, Lanier JM, Bridgewater K, Myer GD. A Novel Approach to Evaluate Brain Activation for Lower Extremity Motor Control. Journal of Neuroimaging. 2019;29(5):580-588.
The authors have provided us with three take-home messages they believe highlight the relevance for their novel methodological work in regard to improving patient care: 
  • Neuroimaging can capture brain activity for loaded multi-joint lower extremity sensorimotor control reliably.
  • This neuroimaging paradigm can be used to determine changes in brain activity from an intervention or injury.
  • This more ecologically relevant assay of neural activity for lower extremity sensorimotor control may provide new insights into lower extremity injury prevention and rehabilitation design.
Clinical Opinion
Dr. Terry Grindstaff, Associate Professor at Creighton University and 20 years of experience as a dual credentialled Physical Therapist and Athletic Trainer, provides his clinical view on the importance of understanding the underlying mechanism of sensorimotor control. The neuroimaging techniques utilized by Grooms et al. are advancing our knowledge of the mechanisms behind rehabilitation programs and giving mechanistic researchers the basis for understanding the true neurological effects interventions have during the recovery of motor control. There is still a disconnect between neuroimaging mechanisms and clinical practice. Dr. Grindstaff believes the first step in connecting the dots is by “taking a step back” from simply treating localized joint injuries and “also looking to the brain and spinal cord as the central driver and their influence in the recovery process.” As an example, Dr. Grindstaff talks about a patient recovering from an ACL reconstruction: “if a patient is struggling with something simple like a post-op quad sets, they have to look at their quad more, or they have to really think about doing an exercise, maybe the patient is trying to tell us something very early on. Maybe the patient is starting to lay down a maladapted motor pattern. We should figure out what are the different ways we can cue an exercise or better address impairments that contribute to these bad patterns so we can potentially better restore function.” He goes on to say maybe we need to add a visual perturbation to these tasks and to challenge different aspects of the sensorimotor system in order to guide patients into a better neurocognitive pattern.

 Clinicians are good at focusing their efforts at the specific joint that is injured and is it difficult to “wrap our head around these true neuromuscular consequences of an injury and what to do about them.”  He also explains researchers like Dr. Grooms is using knee injuries as a model to understand these mechanisms but that “the neurocognitive influence and approach is probably the same for someone having an ACL reconstruction as it is for an ankle sprain or low back injuries.” In order to begin to understand the influence of the brain in the rehabilitation process, Dr. Grindstaff urges clinicians to be “more intentional and purposeful in their thinking” about specific reasons certain exercises are being prescribed. For example, incorporating a balance task on a foam pad with eyes closed is a great exercise to challenge balance, but clinicians should understand what each of those manipulations is adding to the neurocognitive rehabilitation following joint injury. A balancing task targets the somatosensory system, but it also has a vestibular and visual component. “Clinicians should be intentional with exercise prescription with the awareness of the neurocognitive.” Further, clinicians should understand the brain is going to be affected by any joint injury, but we should better determine which responses help best maximize patient function and health.
