Context. Most of the information found in the literature only provides suggestions as to what exercises to use for strengthening and rehabilitation programs with very few if any studies evaluating the benefits of the exercises. Objective. The purpose of this study is to determine whether there will be a difference between the Open Kinetic Chain/Closed Kinetic Chain (OKC/CKC) group and Open Kinetic Chain/Closed Kinetic Chain/Core Stability (OKC/CKC/CS) group, and control group following a six week training program on throwing accuracy, proprioception, and core endurance. Design. This study was a 2x3 factorial design with group (experimental groups and a control group), and time (pre and post). The dependent variables included Functional Throwing Performance Index (FTPI), Closed Kinetic Chain Upper Extremity Stability Test, Back Extensor Test, 45Ad Abdominal Fatigue Test, Right Side Bridging Test, and Left Side Bridging Test. Setting. At a Division III college in western Pennsylvania. Patients and other participants. Subjects consisted of 19 healthy baseball athletes (20.000 +/- 1.54 years, height 177.127 +/- 5.67 cm, and mass 90.391 +/- 22.597 kg) from a division III collegiate setting. The baseball athletes were randomly assigned into the two experimental groups. The control group consisted of healthy age, gender, and activity level matched individuals from the same institution. Interventions. Pre and post-test measurements for throwing accuracy using the Functional Throwing Performance Index (FTPI), upper extremity proprioception using the Closed Kinetic Chain Upper Extremity Stability Test, and core endurance using the Back Extensor Test, 45Ad Abdominal Fatigue Test, Right Side Bridging Test, and Left Side Bridging Test were conducted. The six week protocol for the experimental groups was conducted following a specific program three times a week for an average of 60 minutes. The battery of Open Kinetic Chain and Closed Kinetic Chain exercises was advanced from week to week. The exercises in the core stability program were also advanced from week to week. Main outcomes measures. There will be a significant difference in pre-test to post-test results of the athlete between the three groups. There will be a significant differences from pre-test to post-test and also for the OKC/CKC/CS group for the Functional Throwing Performance Index, Closed Kinetic Chain Upper Extremity Stability Test, Back Extensor Test, Abdominal Fatigue Test, and Right and Left Side Bridging Test. Results. Significant differences were found for test for within subjects effects for four of the six tests, FTPI (F = 15.696, P =APPENDIX A THE PROBLEM Research Question The glenohumeral joint is a very unstable joint based on static and ...
