The purpose of this study is to examine the effect of a structured pre-athletic event cervical muscle warm-up program on cervical muscle performance.

The purpose of this study is to compare the use of the King-Devick concussion test in the traditional neutral (forward facing) position, to a 45 degree turn of the neck to the left and right.

The purpose of this study is to examine if there is a difference in muscle activity in two different techniques of performing a lunge exercise.

The purpose of this study is to investigate the reliability of a modified King-Devick (K-D) Balance Test in hockey players. The KD test is typically performed in stocking feet.  The modified test under study will be conducted while hockey players are wearing hockey skates in order to evaluate if this modified test might contribute to a quick concussion screen at a hockey rink.

The aim of this study will be to estimate and compare intra-rater reliability and minimal detectable change (MDC) of maximum ankle dorsiflexion (ADF) in persons with lower extremity injury using a weight-bearing lunge test (WBLT) and three clinical measurement tools: (1) standard goniometer; (2) bubble inclinometer; and (3) digital goniometer. 

The purpose of this study is to compare various muscle testing techniques using a hand held dynamometer and a custom made testing device for assessing cervical musculature.

The purpose of this study is to understand recovery, hip and trunk strength in patients after hip arthroscopy. 

The purpose of this study is to investigate the reliability of a mobile app to assess balance in athletes during a concussion assessment
