Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The two intervention groups will receive different exercise regimes:
Group 1. Sensorimotor and kinematic exercise including balance, repositioning, movement sense and oculomotor (eye movement) exercises. Each participant in group 1 will receive 2x 30 min session per week for 4 weeks. These exercise sessions will be supervised one-on-one by a physiotherapist. In addition participants will be required to complete a daily home exercise program consisting of the exercises taught during the sessions. The participants will be requested to perform their home exercises for 30 minutes, at least 4 times a week. Progression of exercise difficulty level and dossage will be updated every week according to the patient's progress. For example, balance may be challenged with unstable surfaces, single leg stances, number of repetitions and combination of a few tasks may be used in order to increase level of difficulty.

Group 2. Sensorimotor and kinematic exercise plus interactive exercises using the virtual reality system (VR glasses equipped with a tracker). Patients will interact with visual targets in a customised video game displayed in the VR glasses. This game will be controlled by head movement. Each participant in group 2 will receive 2 x 30 minute sessions per week for 4 weeks using the VR device. The VR exercise sessions will be supervised, one-on-one, by a physiotherapist. Patients will also be prescribed and progressed with home sensorimotor and kinematic exercises. Similarly to group 1, the participants in group 2 will be requested to perform their home exercises for 30 minutes, at least 4 times a week. Progression of exercise difficulty level and dossage will be updated every week according to the patient's progress. For example, balance may be challenged with unstable surfaces, single leg stances, number of repeatitions and combination of a few tasks may be used in order to increase level of difficulty.
The difference between the two groups is the use of the VR interactive system which will be included in the intervention of group 2 alone.

Outcomes
Primary outcome [1] 287376 0
Disability as assessed by the Neck Disability Index
Timepoint [1] 287376 0
Baseline, at week 5 from randomization, and at 3 & 6 months follow up.
Primary outcome [2] 287378 0
Cervical range of motion as assessed by the virtual reality system. The VR glasses are equipped with a tracker, including accelometers, gyropscopes and compass based sensors. Head motion data is collected during the assessment and analysed in customised software, resulting range of motion measures. Cervical range of motion will be assessed using the motion tracking sensors of the VR device. This has previously demonstrated reliability and repeatability for this measure.

Baseline, at week 5 from randomization, and at 3 & 6 months follow up.
Primary outcome [3] 287379 0
Cervical motion velocity and smoothness as assessed by the virtual reality system. The VR glasses are equipped with a tracker, including accelometers, gyropscopes and compass based sensors. Head motion data is collected during the interactive session using VR. The motion data collected is analysed in a customisedcustomised software and produces a velocity profile including multiple kinematic parameters such as velocity and smoothness of neck motion. Cervical motion, velocity and smoothness will be assessed using the motion tracking sensors of the VR device. This has previously demonstrated reliability and repeatability for this measure.

Secondary outcome [3] 298034 0
Cervical spine joint repositioning:Cervical joint position sense will be measured using the three-space Fastrak system (Polhemus, Navagation Science Division, Kaiser Aerospace Vermont). The Fastrak is a non-invasive electromagnetic device which tracks the positions of sensors in relation to a source in three-dimensions and has also been shown to demonstrate a good reliability and validity. Two sensors: one sensor placed on the forehead via attachment of a light weight headband, the second over the spinous process of C7, will continually record the positions of the head relative to a transmitter source during the entire test sequence. A software program written to format and process the data for three-dimensional analysis of the starting position (zero) and the position to which the head returned will be used. The difference between the starting (zero) and position on return to the starting position will be calculated in degrees for the return from head rotation from the right and left. In this test, the subject is instructed to focus on the natural resting head position for a few seconds, actively rotate the head away, and then try to return to the starting position as accurately as possible while vision is occluded.

Secondary outcome [4] 298035 0
Balance will be measured using a computerised, stable force platform (40 X 60 centimetres) The ground reaction forces are registered by force transducers located in each corner of the plate to measure force changes over time in both the ML and AP directions. The signals will be recorded on a computer and the raw traces produced both numerically and graphically (Kistler 9286AA, North America). A total of 4, 30-second tests will be performed. These will include standing in comfortable stance with eyes open and eyes closed and then repeated while the subject is standing on a 10cm high-density piece of foam placed on the platform. In all tests, subjects will be asked to stand as steadily and quietly as possible with their arms by their sides for 30 seconds. A custom made Matlab program will calculate the total energy and RMS for each test.

delete the sentence "by pulling a note out of a box."
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients will initially be stratified according to whether or not they have at least one deficit in sensorimotor values (greater than 2 sd of the mean value for control subjects for either joint position sense or balance). Subjects will either be labeled sensorimotor + or –ve. Block randomisation using a randomisation table generated by a computerised sequence will then be used for each subject according to the stratified group they are allocated to.
