Low Back Pain and Motor Control in Soccer Players

Study Overview
=================
Brief Summary
-----------------
Identification of the effects of low back pain and motor control influence on soccer players performance.

Detailed Description
-----------------
At least 60 volunteer athletes who playing soccer at least 3 years, not away from field more than 2 weeks, 16 years and older are planned to include this study. All participating athletes in this study will be signed an informed consent form then their demographic information will be recorded. To evaluate disability due to low back pain, musculoskeletal problems and the willingness to participate in sports will be used the Oswestry Disability index, the Nordic Musculoskeletal System questionnaire and the Sport Motivation Scale-2, respectively. The motor control levels of the athletes will be assessed with the motor control test battery (MKTB), the core stability with the Sahrmann's core stability test, core muscles endurance with the sport-specific endurance plank test and side bridge endurance test, the static balance with the stand stork test, the dynamic balance with the lower quadrant y balance test, postural changes with the Corbin Posture Rating Scale, the agility with the T test, speed and coordination with 4-10 shuttle run test, explosive force with long jump test, the kinetic chain with the functional movement screen.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Motor control disorder | Motor control test battery: the test consists of ten different tests (forward bend, return from forward bend, sitting forward lean,sitting knee extension, pelvic tilt, one leg stance,side bending, rocking forward, prone knee flexion, hip abduction).Whether the total score increases, the motor control disorders increase. | baseline | 
| Core stability | Sharmann's core stability test | baseline | 
| Core muscles endurance | Sport-specific endurance plank test, right and left side bridge endurance test | baseline | 
| Static balance | Stand Stork test | baseline | 
| Dynamic balance | Lower quadrant y balance test | baseline | 
| Agility | T test | baseline | 
| Speed and coordination | 4-10 Shuttle run test | baseline | 
| Explosive power | Standing long jump test | baseline | 
| Kinetic chain | Functional movement screen | baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Nordic Musculoskeletal System Questionnaire | Evaluates the musculoskeletal system problem. If the athlete indicate a musculoskeletal problem different than low back pain, it will use for screening. | baseline | 
| Sport Motivation Scale-2 | Evaluates willingness to participate in sports. The scale has 6 subparameters indicating sport motivation levels is high or low. | baseline | 
| Oswestry Disability Index | Evaluate disability due to low back pain. the index measures perceived low back pain related dysfunction. Whether the total score increaeses, the dyscfunction increases. | baseline | 
| Postural changes | Corbin Posture Rating Scale. Whether the total score increaeses, thepostural problems increases. | baseline |
