AuriculoTherapy NeuroImaging

Mechanistic Clinical Trial of Auricular Stimulation and Cryogenic Auriculotherapy in Patients With Chronic Low-back Pain, Using Functional Near-infrared Spectroscopy and Magnetic Resonance Imaging

Enrollment

60 participants

Start Date

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.

Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This clinical trial is studying a medical device called Cryo-auriculotherapy, Experimental auricular stimulation, and others for people with back pain lower back chronic, back pain without radiation, and other related conditions. The study is currently recruiting participants at 1 location. People eligible for this study include aged 18 Years and older.

Interventions

DEVICECryo-auriculotherapy

The cryo-IQ device (containing compressed nitrous oxide) with a narrow-tip nozzle will be used. After disinfection of the device and both ears, 7 inter-related points in the auricular cartography will be treated with a 1-2 second application of cold gas, applied to both ears. Treatment points will be: mesoderm master, spine, reticular formation, sensory master point, thalamus, adrenocorticotropic hormone, and corpus callosum.

DEVICESham auriculotherapy

For the sham procedure, an empty gas canister will be used in the cryo-IQ device. This will make the same noise and temporary skin imprint on the ear, but does not deliver any cooling effect. The same 7 ear points will be sham-treated in a protocol that is imperceptibly different from the verum auriculotherapy treatment.

OTHERExperimental auricular stimulation

Three points on each ear will be repeatedly stimulated with a plastic (von Frey) filament. This will be felt, but not be painful and should not result in lasting irritation.
