Pilot Testing A Theory-Driven Self-Management Intervention for Chronic Musculoskeletal Pain

The proposed randomized control trial will evaluate auricular point acupressure (APA) treatment administered by the participant themselves with the use of a phone app on chronic musculoskeletal pain (CMP) outcomes.

This study will randomly assign participants into three groups: (1) Self-guided mAPA (S-mAPA), (2) In-Person Training + mAPA (IP-mAPA), and (3) Usual Care Control (UC). EMA will be used to assess momentary pain outcomes and APA adherence.

Data will be collected at pre- (T1), post-completion of intervention (T2), follow-ups at post 1M- (primary endpoint) (T3), 2M (T4), and 3M (secondary endpoint, long-term sustained effect) (T5) for a total of four assessments.

Chronic musculoskeletal pain (CMP) is the most common self-reported and clinically diagnosed pain condition in the US and costs up to $635 billion annually. Analgesics/opioids are the most common treatments utilized by patients with CMP, however, unnecessary opioid use has resulted in the current opioid epidemic. The Institute of Medicine recommended guidelines for non-pharmacologic, self-management strategies to manage pain. However, these guidelines have not been broadly implemented due to time constraints among healthcare providers, accessibility, patient's beliefs/motivations, and high cost/insurance coverage, especially among socioeconomically disadvantaged and vulnerable patients.

Auricular point acupressure (APA), a non-invasive procedure, provides acupuncture-like stimulations on ear points using small pellets instead of needles to self-manage pain. The investigator's interdisciplinary team has accumulated extensive evidence (11 clinical trials) supporting the efficacy of interventionist-administered APA to manage pain. The randomized clinical trial (RCT) comparing APA to sham APA demonstrated: (1) Significant rapid and sustained effect: APA resulted to ≥38% rapid pain relief among participants at three minutes post-APA; \>44% pain relief and \>28% improved physical function at follow-up after 4-weeks APA; (2) Reduced use of medications: After 4-weeks of APA, ≥60% of participants reported less use of pain medications; and (3) Significant impact on physiological measures: APA controls pain through blocking pro-inflammatory cytokines (IL-1β, IL-2) and modulating nerve sensitivity. No adverse effects from APA were reported.

The investigator's long-term goal is to eliminate pain care disparities and reduce society's reliance on opioids to manage pain. Leveraging technology, the proposed study will help advance mAPA, a novel, easy-to-initiate, rapid, safe, and non-pharmacologic tool incorporated in a self-management plan to manage pain in real-world settings. The proposed intervention promises to provide important and timely information to advance a non-opioid and self-managed pain treatment.

* Chronic pain ≥ 4 on a scale of 0-10 point numerical pain, persisting for at least 3 months or has resulted in pain on at least half the days in the past 6 months.

Exclusion Criteria:

* Disease that might confound therapeutic effects or explanation of outcomes, i.e., infection, malignant tumors, or autoimmune diseases.
* Severe ear skin issues.
* Use of some types of hearing aids (size may obstruct the placement of seeds)
* Concurrent major psychiatric disorder (i.e., participant self-report).
* Pregnant women will be excluded from the study based on the self-reported data.
