Methods: One group of 20 participants aged 18-23 from a Midwestern university performed a pre-test/post-test on a computerized posturography plate to determine Center of Pressure (CoP) and Limit of Stability (LoS) scores. Participants performed three 20-30 minute sessions per week of balance and proprioceptive training using a Balance Bow for a period of four weeks. Data were analyzed (SPSS 21.0) using a dependent t-test to determine if any changes occurred between pre- and post-test scores after four weeks. Results: The analyses found no significance difference in Center of Pressure (CoP), normal stability eyes open (NSEO), normal stability eyes closed (NSEC), perturbed stability eyes open (PSEO), perturbed stability eyes closed (PSEC), or LoS forward (F), backward (B), or right (R) scores in college-aged participants. A significant difference was found in LoS left (L) and a notable trend towards significance was found in LoS R results. Conclusion: With the exception of LoS L stability scores, it was concluded that 12 sessions of 20-30 minutes, utilizing a slack line device, over a four week training period did not significantly improve stability and proprioceptive scores of the ankle in college-aged participants

Reliability of the sitting hand press-up test for identifying and quantifying the level of scapular medial border posterior displacement in overhead athletes

While scapular internal rotation has been listed among the forms of scapular dyskinesis there has not been a reliable test documented in the literature that examines this motion. The purpose of this study was to determine whether an innovative scapular medial border posterior displacement measurement device has adequate inter-rater and intra-rater reliability when used at rest and during the sitting hand press up test. 16 male Division III baseball players free of upper limb injury for the previous 12 months participated in the study. Posterior scapular displacement measures were taken on each subject in a resting static posture and while performing a sitting hand press up test. Subjects were tested twice within 24 ho...
