PRoGReSS-PS: Patient Response to GRraded Sensory Stimulation: A Pilot Study

This treatment will be applied to the low back region only. During a HVLA treatment, the study doctor will ask the participant to lie on their side on a treatment table. After carefully helping the participant into the proper position, the doctor will make a quick and controlled push with their hand to slightly move joints in the low back. During this procedure, the participant may feel and/or hear a popping sound. After treatment, the doctor may ask the participant to rest on the table for a few moments. During palpation procedure, the doctor will touch several areas in the low back while asking questions about pain, tenderness and other sensations felt during this procedure. The participant will watch the doctor perform the palpation procedure in real time with a tablet computer.

The study doctor will perform a massage of each foot while the participant lies face up in a relaxed position on a treatment table. The procedure will last approximately 10-20 minutes including massage to the toes, heel, sole, and top of each foot.
