Motor Performance of Asymptomatic and Chronic Neck Pain Participants Pre- and Post-spinal Manipulation Using an Eye and Head Movement Fitts' Task
In Brief
A clinical study evaluating High velocity/low amplitude cervical spine manipulation for Chronic Neck Pain. Completed, enrolled 40 participants across 1 site.
Detailed Summary
The objective of this study is to quantify motor performance, this study will use an eye movement Fitts' task to examine the effects of cervical spine manipulation on participants with chronic neck pain and the subsequent changes to saccade movement time. This study will also include a head movement Fitts' task which has previously reported a reduction in head movement time in chronic neck pain participants after cervical spine manipulation. This is an observational within-subjects design that involves a pre/post cervical spine manipulation intervention on participants (n=20) with chronic neck pain and asymptomatic controls (n=20). All participants will complete an eye movement and head movement Fitts' task before and after cervical spine manipulation to identify any changes in saccade and head movement time, saccade and head peak velocity, and time to peak saccade and head velocity.

Timeline
Interventions
The participants will receive a single cervical spine rotary manipulation to the previously identified palpable cervical segmental fixation. During the performance of the manipulation, the supine participant will rest their arms at the sides of their body. Next, the index finger of the chiropractor's contact hand will be placed on the lamina of the restricted cervical segment. The chiropractor will then rotate the participant's head contralaterally until the barrier of the cervical segments volitional end range is reached. The chiropractor's other hand will be placed behind the participant's head to induce gentle neck rotation contralateral to the chiropractor's thrusting hand. The chiropractor will deliver a manual thrust, with the thrust vector directed towards the participant's opposite eye.
