Neck Motion and Motor Control in Chronic Neck Pain and Associations With Clinical Symptoms

Study Overview
=================
Brief Summary
-----------------
The primary purpose of this study is to investigate if there is altered motor control of head and neck in chronic neck pain patients compared with healthy persons. In addition, associations between neck pain, motor control, disability and function, and clinical symptoms will be studied in patients following physiotherapy treatment in primary health care.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Conjunct motion | Describes the movement stiffness in active movements of the neck. Conjunct motion is movement in the two associated movement planes to the primary plane. For example,the amount of rotation and lateral flexion during neck flexion and extension. Measured by 3D Liberty device and with degrees as unit of measure. | up to 8 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| head motion smoothness | Measured by a 3D Liberty device and with velocity(degrees/s)as unit of measure | up to 8 weeks | 
| reposition accuracy | Measured by 3D Liberty device and with degrees as unit of measure | up to 8 weeks | 
| postural sway. | Measured by 3D Liberty device and trunk sway as a unit of measure | up to 8 weeks | 
| Head stabilization | Measured by 3D Liberty device and with velocity (degrees/second) as unit of measure | up to 8 weeks | 
| pain | a numerical pain rating scale will be used to measure neck pain. | up to 24 weeks | 
| Head motion accuracy | Head motion accuracy will be measured by a 3D Liberty device and centimeter will be used as a unit of measure | up to 8 weeks |
