Experimental
Active Comparator
Spinal Treatment
Foot Massage
Participant receives High Velocity Low Amplitude Spinal Manipulation (HVLA) to the low back only from a doctor of chiropractic. Also receives focused palpation procedures to the low back paired with visual input of these procedures using a tablet computer. During a HVLA treatment, the study doctor will ask the participant to lie on their side on a treatment table. The doctor will make a quick and controlled push with their hand to slightly move joints in the low back. 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 doctor of chiropractic 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.
