This observational study aims to learn how to measure joint motion and tissue response when pressure is applied to the back and examine how the nervous system responds to the applied pressure. This pressure or mobilization technique is a standard care but we currently do not have a method to measure this technique. Through this study, we hope to validate a tool that allows physical therapists to measure the pressure applied during spinal mobilization. Participants will be asked to: * Receive spinal mobilization * Participate in pain threshold testing * Answer questionnaires

Change in pain threshold as measured by quantitative sensory testing.
The following tests will be used to test sensation threshold before and after grade I - IV mobilization/clinician: pressure pain threshold, conditioned pain modulation, and temporal summation.
Time frame: Change from Baseline (day1) to immediately post-treatment (day 1)

Functional near infrared spectroscopy (fNIRS) is a portable, non-invasive, and inexpensive brain imaging method of monitoring cerebral hemodynamic activity.
Time frame: Change from Baseline (day1) to immediately post-treatment (day 1)
