Patellar Tendon Straps Decrease Pain And May Alter Lower Extremity Kinetics In Those With Patellar Tendinopathy During Jump Landing, Adam B. Rosen, Jupil Ko, Kathy J. Simpson, Cathleen N. Brown

Health and Kinesiology Faculty Publications

Patellar tendinopathy is often managed with a patellar tendon strap, however, their effectiveness is unsubstantiated. The purpose of this study was to determine if straps altered pain or lower extremity kinetics of individuals with patellar tendinopathy during landing. Thirty participants with patellar tendinopathy and 30 controls completed drop jumps with and without patellar tendon straps. Wearing the strap, tendinopathy participants demonstrated significantly decreased pain and reduced knee adductor moment; all participants displayed significantly decreased anterior ground reaction force while wearing a strap. Patellar tendon strapping may reduce pain due to alterations in direction and magnitude of loading.

Illegitimate Bodies In Legitimate Times: Life, Liberty And The Pursuit Of Movement, Brian Culp May 2017

Illegitimate Bodies In Legitimate Times: Life, Liberty And The Pursuit Of Movement, Brian Culp

Faculty Articles

Drawing on Michel Foucault’s concepts of state racism and biopower, the author of the 26th Delphine Hanna Lecture presents several claims: (a) that the idea of the illegitimate outsider in Western world governments like the United States has largely been influenced by ancient Greek ideals, (b) that a host of policies and intentional actions by power brokers create derision and hierarchies between “old” and “new” immigrant groups, and (c) neoliberal ideology couched in actions that aim “to protect the state” is nothing more than a recoding of traditional racist rhetoric that expands systemic racism. The author identifies the capabilities approach, …
