Assessment of Chiropractic Treatment Using Reaction and Response Times in Members of the Special Operation Forces (ACT2)

Participants will receive chiropractic spinal manipulative therapy consisting of High velocity low amplitude (HVLA) spinal manipulative procedures. These procedures are typically associated with a quick manual thrust and a cavitation sound. For the cervical spine, a procedure called a cervical index pillar push, thoracic manipulation will occur with unilateral or bimanual contacts in the prone or supine positions and lumbar/pelvis manipulation will be performed with a procedure referred to as side-lying or side-posture.

Participants randomized to the wait-list control group will complete questionnaires and perform the same study procedures as those randomized to the chiropractic manipulative therapy arm. After completing the required 2-week waiting period, those who wish to receive chiropractic manipulative therapy will be eligible to schedule treatment visits.
