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

Study Overview
=================
Brief Summary
-----------------
A previous study of the Closed Kinetic Chain Upper Extremity Stability Test (EPOLTEST) in a population aged 18 to 25 years isolated 3 main factors influencing the CKCUEST score: upper extremity span, weight, and sex of the individual. A predictive equation for the CKCUEST score was thus established and to date has a capacity to determine the real score of approximately 51%. The results of this first study show that a certain number of variables have not been studied. The purpose of this study, EPOLTEST 2, is to take into account the variables already studied on a larger population (18-50 years old) and to add an assessment of shoulder muscle strength and abdominolumbar endurance.

Design Details

Primary Purpose: Prevention
Intervention Model: Single Group Assignment
Interventional Model Description: This study is a monocentric interventional prospective study
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention<br>All subjects will perform the same tests. | Diagnostic Test: Closed Kinetic Chain Upper Extremity Stability Test<br>* 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.<br>Diagnostic Test: Prone Bridge Test<br>* 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.<br>Diagnostic Test: Measurement of the muscle strength of the shoulder complex<br>* Maximum isometric force of the external and internal rotators and abductors/adductors measured by a dynamometer.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) score | Closed Kinetic Chain Upper Extremity Stability Test/ 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. Three tests are performed. The outcome measure will be the mean of the score of the three tests realisation. | Day 1 | 
| Anthropometric data | Measurement of the subject's weight in kilograms | Day 1 | 
| Anthropometric data | Measurement of the subject's height in centimeters | Day 1 | 
| Anthropometric data | Measurement of the subject's BMI in kg/m^2 | Day 1 | 
| Anthropometric data | Measurement of the subject's upper extremity length in centimeters | Day 1 | 
| Anthropometric data | Measurement of the subject's upper extremity span in centimeters | Day 1 | 
| Anthropometric data | Measurement of the subject's distance between acromion and radial styloid of the right upper limb in centimeters | Day 1 | 
| Anthropometric data | Measurement of the subject's distance between olecranon and radial styloid of the right upper limb in centimeters | Day 1 | 
| Muscular strength of the shoulder complex | Maximum isometric force of the external and internal rotators and abductors/adductors measured by a dynamometer in Newton. | Day 1 | 
| Abdominal-lumbar stability | 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. | Day 1 |
