Trunk Motor Control Performance Before and After Spinal Manipulation Treatment

The overall goal of this project is to develop sensitive and objective clinical research tools for the assessment of trunk motor control. In order to accomplish this goal, the investigators aim to quantify changes in trunk motor control before and after spinal manipulation treatment. The investigators hypothesize that trunk motor control will improve in the low back pain participants after 4-weeks of spinal manipulation treatment. Additionally, the investigators will compare position and force trunk motor control between healthy controls and low back pain patients. The investigators hypothesize that baseline tests of position and force trunk motor control will be better in healthy individuals than low back pain patients.
