  • USA Hockey National Registry for Catastrophic Injuries in Ice Hockey Rochester, Minn.

    The purpose of this USA Hockey registry is to collect information on the prevalence of catastrophic injuries for both genders in youth, high school, junior, college, national program, adult amateur, minor league, and professional ice hockey in the United States.  The goal is to design and maintain a comprehensive registry of catastrophic injuries in ice hockey that will be the primary source of catastrophic ice hockey injury data in the United States. The registry will provide data to support potential rule and equipment changes.

  • Arthrex Primary Total Knee and Unicondylar Knee Registry Rochester, Minn.

    The objective of the study is a multi-center prospective registry to collect clinical outcomes of  knee arthroplasty.


  • Preparing to Treat Concussions in Adolescent Hockey and Football Players Using the "From Ice and Field to the Axon and Astrocyte" Model Rochester, Minn.

    The purpose of this study is to further demonstrate the value of the components of our objective diagnosis and quantification of severity: the NeuroCatch quantified electroencephalogram, the King-Devick test, blood biomarkers, and metabolomics profiling. Wearable accelerometers (Triax SIM-G) and video footage will provide data to correlate concussive injuries with physical parameters and mechanisms of injury. Time on Ice tracking will allow for calculation of Individual Exposure Time (IET).

  • Preparing to Treat Concussions in Hockey Players Using a "From Ice to Axon and Astrocyte Repeated Measures Design" Rochester, Minn., Scottsdale/Phoenix, Ariz.

    The purpose of this study is to demonstrate the value of our objective diagnosis of concussion (ODC) components and to quantify severity. ODC components include: the NeuroCatch™ Platform [quantified electroencephalogram (qEEG)] developed by NeuroCatch Inc., the King-Devick Test (in association with Mayo Clinic) of rapid number naming, and blood biomarkers such as neurofilament light (NfL), neuron-specific enolase (NSE), and S100B.  Wearable accelerometers (Triax Technologies’ SIM-G, X2 Biosystems X Patch, and Prevent Biometrics’ Impact Monitor Mouthguard) and three camera video footage will also provide acceleration data to correlate to concussive injuries and mechanism of injury. Time on Ice tracking will allow for calculation of Individual Exposure Time (IET).
