Effect of Core Stabilization Trainings on Function and Proprioception of Upper Extremity on Physically Active Women with Predisposition to Injury

  Core stability is the ability to control the movement of the trunk for optimal production, transfer, and control of forces from the upper and lower extremities during functional activities. Limited evidence from literature provides a link between core stability, upper extremity, and prevention of injury of upper extremity and thus more investigation are needed. Therefore, the present study was conducted to determine the effect of core stabilization trainings on the function of upper extremity on physically active women with predisposition to injury. In the current study, 23 physically active women with the risk of upper extremity injury participated.Six-week programs, including core-stability exercises that progressed each week, were perfromed. Closed kinetic chain upper extremity stability test, shot medicine ball throw test for function, and error of active angle reproduction of 45 for dominant side for proprioception were used. Also, Shapiro Wilk test was used to examine the normality of the data and to assess the changes in the scores of the tests in each group, ANCOVA was used before and after the training period. The significance level wasα ≤ 0.05. A significant difference was observed between groups on function. Also, an increase was evident in all pretest-to-posttest results in the experimental group. According to the results, core stability training involves the neuromuscular system and increase dynamic stability in the core area. These functional exercises can affect the performance of the entire kinetic chain. The results showed that core stability training improved function and proprioception on upper extremity in physically active women with predisposition to injury. It is also be suggested that different tools be used to examine the function and proprioception in future studies.
