Relationship of Deep Cervical Flexor Muscle Endurance With Neck Position Sense and Body Balance

Study Overview
=================
Brief Summary
-----------------
The aims of this research are to investigate relationship of deep cervical flexor muscle endurance with neck position sense and body balance in non-specific chronic neck pain, and to compare the results with healthy individuals.

Detailed Description
-----------------
The investigation will be included 2 groups which include 30 individuals with non-specific chronic neck pain and 30 healthy individuals. In evaluation of participants, endurance of deep cervical flexor muscles will be measured using Stabilizer Pressure Biofeedback Unit with cranio-cervical flexion test. Pressure rise which increases from 20 mmHg to 30 mmHg with 2 mmHg increments will be performed in 5 stages. There are 10 seconds contractions at every stage and these contractions will be made 10 times. Endurance will be calculated by the cumulative performance index with the information obtained from this test. Neck position sense of 6-direction (flexion, extension, right-left lateral flexion and right-left rotation) will be measured by CROM device (cervical range of motion device). Joint position error will be calculated by taking the average of the absolute angular difference by 3 trial for each direction. Body balace will be measured by Balance Master System. Modified clinical test of sensory interaction balance (mCTSIB), limits of stability (LOS), rhythmic weight shift (RWS), unilateral stance (US), walk across (WA) and step/quick turn (SQT) will be performed.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Endurance of deep cervical flexor muscles | Score of cranio-cervical flexion test will be measured by Stabilizer Pressure Biofeedback Unit. | Baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Neck position sense | Joint position error of 6-direction (flexion, extension, right-left lateral flexion and right-left rotation) will be measured by cervical range of motion device (CROM device). | Baseline | 
| Modified clinical test of sensory interaction balance (mCTSIB) | This test will be measured by Balance Master System. | Baseline | 
| Limits of stability (LOS) | This test will be measured by Balance Master System. | Baseline | 
| Rhythmic weight shift (RWS) | This test will be measured by Balance Master System. | Baseline | 
| Unilateral stance (US) | This test will be measured by Balance Master System. | Baseline | 
| Walk across (WA) | This test will be measured by Balance Master System. | Baseline | 
| Step/quick turn (SQT) | This test will be measured by Balance Master System. | Baseline | 
| Pain | This test will be measured by Visual Analog Scale (VAS) score in activity and rest. VAS has 10-centimeter line corresponding to the amount of pain they experienced. 0 means no pain and 10 means pain as bad as possible. | Baseline |
