The Effect of Adding Auditory Information on Head Movements in People With Traumatic Neck Pain

Study Overview
=================
Brief Summary
-----------------
This study sets out to investigate the potential effect of auditory disturbances on human movement

Detailed Description
-----------------
Clinicians routinely investigate/test human movement but if/how this is effect by auditory disturbances is unclear. This study sets out to investigate the impact of auditory disturbances on head movements.

Official Title
-----------------
The Effect of Adding Auditory Information on Head Movements in People With Traumatic Neck Pain

Conditions
-----------------
Whiplash, Healthy

Intervention / Treatment
-----------------
* Device: Smartphone playing a sound

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Range of motion | Range of motion will be assessed during head rotations (i.e. moving the head from a neutral position to end of range in rotation before returning to the start position) | During a single test session (approximately 45minutes) at day 1 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Head repositioning accuracy | Head repositioning accuracy will be assessed as the error between the starting point and the end point following a head rotation (i.e. moving the head from a neutral position to end of range in rotation before returning to the start position) and will be repressed in degrees. | During a single test session (approximately 45minutes) at day 1 | 
| Quality of head movement | Quality of movement (smoothness) will be determined using calculations of jerk variance (Jerk is the time derivative of acceleration which will be measures using an inertial measurement unit. The measure will be converted to a unitless measure where higher values indicates less smooth movements), assessed during head rotations (i.e. moving the head from a neutral position to end of range in rotation before returning to the start position). | During a single test session (approximately 45minutes) at day 1 | 
| Perceived stiffness during movement | Participants will rate their perceived stiffness during head movement using a 0-100 numerical rating scale, where 0 = no stiffness and 100 = worst stiffness imaginable. | During a single test session (approximately 45minutes) at day 1 | 
| Perceived difficultness of performing movement | Participants will rate the Perceived difficultness of performing head movements using a 6-point Likert scale going from 0 = no problems, 1 = minimally difficult; 2 = somewhat difficult; 3 = fairly difficult; 4 = very difficult; 5 = unable to perform | During a single test session (approximately 45minutes) at day 1 | 
| Perceived neck pain intensity | Participants will rate ant potential pain during the session using a 0-11 numeric rating scale (NRS) with 0 = no pain and 10 = worst imaginable pain | During a single test session (approximately 45minutes) at day 1 |
