Influence of Anthropometric Data, Shoulder Complex Muscle Strength, and Abdominal-lumbar Endurance in Closed Kinetic Chain Upper Extremity Stability Test

Each patient receive the same intervention, the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST). The CKCUEST is a functional test which assess shoulder's stability. Patient is in push-up position, with 91 cm between his hands. His body is straight and his foots are squeeze. patient has to touch his hand with his other one and returns in the initial position. Then, patient repeats this movement with his other hand, etc, during 15 secondes. The CKCUEST score is the movement's number performed.

"The prone bridge test also known as the plank or hover measures the muscular endurance of the abdominal muscles. Subjects will start in the down push up position with their feet together and their hands shoulder width apart. When the test starts the subject will push up to the prone bridge position so they are resting on their hands and toes making sure they maintain a straight line from the shoulders through the hips to the knees. The outcome measure will be the time where the subject stay in this position."
