Trial Parameters
Brief Summary
This is a clinical study of patients who have low back pain (for at least 6 months). The goal is to understand, with brain imaging, how auriculotherapy (an acupuncture-like stimulation of the ear) may work to relieve pain. There are 4 total study visits, divided into two pairs of visits that occur before and 5-7 days after receiving either a real or sham auriculotherapy treatment. The cryo-IQ device will be used, to stimulate 7 small areas on both ears with a focused jet of cold as a small amount of compressed gas is released. This is generally not painful, and less invasive, compared to using needles for auriculotherapy.
