• A Prospective Study Investigating the Immediate Consequences of Knock-outs, Technical Knock-outs and Chokes in Mixed Martial Arts on Brain Function Minneapolis, Minn.

  The purpose of this study is to investigating the impact on the brain of knock-outs, technical knock-outs and chokes in mixed martial arts.

• Characterization of Orthobiologic Agents Used for Point of Care Ultrasound Guided Procedures and Associated Outcomes Rochester, Minn., Minneapolis, Minn., Jacksonville, Fla.

  The purpose of this study is to determine patient and manufacturing factors that influence orthobiologic agent (OBA) product components and determine how they may influence patient outcomes.

• Inter-Rater and Intra-Rater Reliability of Measuring the Ischiofemoral Space Between Sonographers of Differing Experience: A Pilot Study Rochester, Minn.

  The ischiofemoral space (IFS) has been evaluated with radiographs, CT, and magnetic resonance imaging (MRI). Recent studies have questioned the reliability of IFS measurements taken without controlling hip position. In recent years the utilization of outpatient musculoskeletal ultrasonography (MSK US) increased has increases dramtically. MSK US offers many benefits to a musculoskeletal practice, including rapid diagnosis of disorders of bones, joints, tendons, muscles, ligaments, blood vessels, and nerves, as well as the ability to guide interventions to treat these structures. The primary aim of this study is to evaluate the inter-rater and intra-rater reliability of US measurements of the IFS.  A secondary aim is to determine whether operator experience affects the inter-rater or intra-rater reliability of these measurements. 

• Retrospective Review of Clinical Complications from the Use of Office-based, Micro-invasive Procedures in a Tendinopathy Clinic Rochester, Minn.

  The purpose of this study is to retrospectively evaluate the complication rate and outcomes of ultrasound-guided micro-invasive surgical procedures performed at 6 institutions. 

• The Effect of a Home Training Program on Preferred Step Rate in Recreational Runners Rochester, Minn.

  This will be a pilot study to determine if a 6 week home training program can increase preferred step rate (cadence) in recreational runners. Increase in step rate has been correlated with decreased stress at lower limb joints in runners. This has the potential of decreasing overuse injuries in this population. Research participants will have their preferred cadence evaluated at the beginning of the study. The athletes will be randomly assigned to two groups. One group will continue to train without intervention and the other group will train at a cadence of 10% higher than their preferred step rate. At the end of 6 weeks the participants will have their preferred cadence reevaluated using the same method as pre-participation cadence was determined. The investigators hypothesis the preferred running cadence of recreational runners following the intervention will be 5-10% greater than prior to the intervention and the increased cadence will be maintained for 6 months following the intervention.

• The Utility of Diagnostic Ultrasound in the Evaluation of Athletes with Vocal Cord Dysfunction: A Proof of Concept and Feasibility Study Rochester, Minn., Minneapolis, Minn.

  The purpose of this study is to find out if we can use ultrasound to identify people with breathing problems from their vocal cords. Ultrasound machines use sound waves to see inside your body. In this case, we will be looking at the vocal cords in your neck. If we can use ultrasound to see this problem, then we won’t need to use a camera inside of a person’s throat to diagnose this problem.

• Ultrasound Assessment of Weightbearing and Non-Weightbearing Meniscal Protrusion: A Reliability Study Rochester, Minn.

  The purpose of this study is to determine the intra-rater and inter-rater reliability of US measurements of meniscal protrusion with and without weight bearing.
