Full description

The Patient Response to Graded Sensory Stimulation Pilot Study (PRoGReSS-PS) will measure back pain perceptions in participants who receive either chiropractic treatment or foot massage. In this study, the researchers will:

1. Measure the participant's back pain and function using research forms.
2. Test the participant's ability to discern different touch sensations in the low back.
3. Assess the participant's perceptions of the study procedures on research forms during the study and in a short interview at the end of the study.

Spinal Treatment

Experimental group

Description:

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.

Treatment:

Procedure: Spinal treatment

Foot Massage

Active Comparator group

Description:

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.
