Management of Chronic Low Back Pain in Older Adults Using Auricular Point Acupressure

Study Summary

Almost one-third (30%) of persons 60 years and older suffer from cLBP and cause a significant negative impact on individuals and society in the U.S. The goal of managing cLBP is decreased pain and disability.To accomplish this, cLBP sufferers often use analgesics including opioids to decrease pain and facilitate activity, but the side effects caused by these medications are problematic. A better pain management strategy clearly needs to be developed. The investigators propose to test auricular point acupressure (APA), a non-invasive, easily administered, patient-controlled, and non-pharmacological strategy, to provide rapid, safe, and an innovative solution for chronic low back pain (cLBP) in older adults. APA involves an acupuncture-like stimulation of the ear without needles. With APA, small seeds are taped to specific ear points. The patient is taught to apply pressure to the seeds, with the thumb and index finger, three times a day (morning, noon, and evening) for three minutes each session to achieve pain relief. The investigators have developed a detailed APA protocol to teach health-care providers without experience in acupuncture and traditional Chinese Medicine that investigators can learn about APA in brief educational seminars as a treatment including the systematic identification of ear points (called auricular diagnosis). The investigators teach methods that enable patients to continue using APA to self-manage participants' pain. Brain imaging studies in acupuncture indicate that acupuncture can restore normal functional connectivity related to pain reduction. Studies suggest that stimulation of ear points (1) excites the somatotopic reflex system in the brain and that pathological brain patterns are electrically reset to stop the unwanted activation of spinal pain pathways, explaining the possible immediate pain relief that patients feel after APA and (2) cause a broad spectrum of systemic effects, such as vasodilation, by releasing endorphin to elic

Primary Outcome

Pain intensity as assessed by the NRS for worst pain in the past 7 days using a 0-10 scale (0 = "no pain" and 10 = "worst pain imaginable")

Interventions

• OTHER Target ear points related to chronic low back pain (T-APA)
• OTHER Non-Target ear Points not related to chronic low back pain (NT-APA)
• OTHER Enhanced Educational Control Group (CG-2)
