High Prevalence Of Nontraumatic Shoulder Pain In A Regional Sample Of Female High School Volleyball Athletes, Kayt E. Frisch

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Background: Shoulder pain is becoming increasingly problematic in young players as volleyball gains popularity. Associations between repetitive motion and pain and overuse injury have been observed in other overhand sports (most notably baseball). Studies of adult athletes suggest that there is a shoulder pain and overuse problem present in volleyball players, but minimal research has been done to establish rates and causes in juvenile participants.

Purpose: To establish rates of shoulder pain, regardless of whether it resulted in a loss of playing time, in female high school volleyball players. A secondary goal was to determine whether high repetition volumes correlated …

Interleukin-1 Receptor Antagonist Modulates Inflammation And Scarring After Ligament Injury, Connie S. Chamberlain, Ellen M. Leiferman, Kayt E. Frisch, Sarah E. Duenwald-Kuehl, Stacey L. Brickson, William L. Murphy, Georffrey S. Baer, Ray Vanderby

Ligaments have limited regenerative potential and as a consequence, repair is protracted and results in a mechanically inferior tissue more scar-like than native ligament. We previously reported that a single injection of interleukin-1 receptor antagonist (IL-1Ra) delivered at the time of injury, decreased the number of M2 macrophage-associated inflammatory cytokines. Based on these results, we hypothesized that IL-1Ra administered after injury and closer to peak inflammation (as would occur clinically), would more effectively decrease inflammation and thereby improve healing. Since IL-1Ra has a short half-life, we also investigated the effect of multiple injections. The objective of this study was to …
