Muhammad Waseem, Sabeeda Kadavath, Swathi Sethuram, Husayn Al-Husayni and Gerard Devas

Article Type: Case Report | First Published: April 17, 2015

Apophyseal avulsion fractures are almost exclusive to the adolescent population. It has been commonly associated with sports injuries. In our case reports, we identify two cases of these apophyseal avulsion fractures with no history of routine physical activity. In the context of our patients, identifying causation of hip pain was essential to understanding the mechanism of any trauma resulting in fractures. The adolescents presented in this case series reported a history of mosh pit activity af...

Electromyographic Cross-Spectral Analysis of Antagonist Muscle Coactivation

Travis W. Beck

Article Type: Research Article | First Published: March 20, 2015

The purpose of this study was two-fold: (1) to compare the responses for traditional EMG amplitude measures with those from the crossspectrum approach for assessing agonist-antagonist interaction, and (2) to examine changes in the agonist-antagonist interaction for the elbow flexors and extensors with increases in movement velocity. Eighteen healthy, college-aged subjects (mean ± SD age = 21.8 ± 2.7 yrs) volunteered to perform maximal, concentric isokinetic contractions of the dominant elbow fle...
