Control: postural education, general range of motion and strengthening in addition to the standard of care rest followed by graded exertion. Individuals were seen once weekly for eight weeks or until time of medical clearance to return to sport.
Physiotherapy: including vestibular rehabilitation and multimodal treatment for the cervical spine, once weekly with the study physiotherapist for 8 weeks or until time of medical clearance to return to sport.

Change in Dynamic Visual Acuity
Assessed clinically using an eye chart and a metronome set at 2 Hz. Static visual acuity is measured 13 feet from the target. The subjects head is rotated at 2 Hz and visual acuity is measured dynamically. The difference between static and dynamic visual acuity is calculated.
Time frame: Change between Baseline and 8 weeks or time of medical clearance
Head Thrust Test
Clinical test performed in sitting with head flexed and high velocity low amplitude motion into 5-15 degrees rotation is performed while the subject is asked to maintain focus with the examiner's nose.
Time frame: Baseline and at 8 weeks or time of medical clearance
Change in modified Motion Sensitivity Test Score
Patient report of intensity and duration of dizziness with eight head or body motions
Time frame: Change between Baseline and 8 weeks or time of medical clearance
Change in Functional Gait Assessment Score
Dynamic Balance Measure that includes 10 different movements and the ability to complete each activity is rated by the examiner.
Time frame: Change between Baseline and 8 weeks or time of medical clearance
Change in Cervical Flexor Endurance
Test to evaluate the time (seconds) that an individual can maintain the head in a position of craniovertebral flexion and two finger widths above a pillow in crook lying.
Time frame: Change between Baseline and 8 weeks or time of medical clearance
Change in Joint Position Error
Clinical test using a laser pointer affixed to a head piece on top of the head that is projected onto a bull's eye target. Subject rotates head to left, right (rotation) or up (extension) to the maximum comfortable range and relocates to the perceived point of neutral head position with eyes closed. A measures from the centre of the bull's eye is recorded. A mean of three trials is recorded for each direction.
Time frame: Change between Baseline and 8 weeks or time of medical clearance
