The Effects of Spinal Manipulation on Performance on Neck Pain Patients During a Fitts' Task

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.
