Registration Number: NCT03589703

Lead Sponsor: The University of Texas Health Science Center, Houston

Brief 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 elicit short-term analgesic effects or neuropeptide-induced anti-inflammatory cytokines, which may explain long-term effects.

The Ecological Momentary Assessment (EMA) smart phone app will be used to collect real-time cLBP outcomes and adherence to APA practice. Treatment and nonspecific psychological placebo effects will be measured via questionnaires for all participants. Neuro-transmitters is measured by inflammatory biomarkers. Blood samples will be collected for serum collection and a multiplex bead-based immunofluorescence assay performed to check for serum levels. Mini-Mental State Examination will be used to screen for cognitive function, also HRQoL, satisfaction, treatment beliefs and expectations, sleep, relaxation effects, catastrophizing and fear/avoidance, and placebo effects will be measured.

Recruitment & Eligibility

Status: COMPLETED

Sex: All

Target Recruitment: 272

Inclusion Criteria

Age 60 years or older
Able to read and write English
cLBP that has persisted at least 3 months and has pain on at least half of the days for the previous 6 months
Average intensity of pain ≥ 4 on a 11-point numerical pain scale in the previous week

Arm && Interventions

Group	Intervention	Description
NT-APA	Non-Target ear Points not related to chronic low back pain (NT-APA)	The same procedure for APA will be applied but the tapes/seeds will be placed on five different ear points, comprising mouth, stomach, duodenum, internal ear, and tonsil. These points are chosen for the non-target ear points of APA treatment for two reasons. First, they are distinct from the zones of the ear (and the points therein) associated with the lower back, and correspond to body regions in which the participant is usually pain-free. Second, they are equivalent in number to those points used in the APA treatment group.
Enhanced Educational Control Group (CG-2)	Enhanced Educational Control Group (CG-2)	Participants in the enhanced educational control group will be given the cLBP educational booklet and visit the office weekly for assessment (i.e., blood draws and questionnaires), which is the same schedule as that for the APA groups.
T-APA	Target ear points related to chronic low back pain (T-APA)	Patients with active points related to cLBP. Will receive acupressure within the two zones for cLBP located on the front and back of the ear and three points known for alleviating stress and pain.

Primary Outcome Measures

Name	Time	Method
Physical Function as Assessed by the Roland Morris Disability Questionnaire (RMDQ)	1 month post completion of the treatment (2 months after baseline)	The Roland Morris Disability Questionnaire (RMDQ), 24-item measure, is used to assess the impact of back pain on their daily functioning. The score ranges from 0 (no disability) to 24 (maximum disability).
Pain Intensity as Assessed by the Numeric Rating Scale (NRS)	1 month post completion of the treatment (2 months after baseline)	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")
Pain Interference as Assessed by the Brief Pain Inventory-short Form Pain Interference Subscale	1 month post completion of the treatment (2 months after baseline)	Pain interference is assessed by the Brief Pain Inventory pain interference subscale, which uses a 0-10 scale (0 = "does not interfere" and 10 = "completely interferes").

Secondary Outcome Measures

Name	Time	Method
Number of Participants Who Use Opioids	1 month post completion of the treatment (2 months after baseline)
APA Treatment Satisfaction as Assessed by Satisfaction Survey	1 month post completion of the treatment (2 months after baseline)	Satisfaction is assessed using a 5-point numeric rating scale: 1. - Completely satisfied 2. - Somewhat satisfied 3. - Neither satisfied nor dissatisfied 4. - Somewhat dissatisfied 5. - Very dissatisfied
Quality of Life as Assessed by the Patient-Reported Outcomes Measurement Information System (PROMIS-29) - Depression	1 month post completion of the treatment (2 months after baseline)	The Patient-Reported Outcomes Measurement Information System (PROMIS-29) is a 29-item profile instrument that can be used to assess seven subscales of health quality of life (QOL) for each of 7 domains-this outcome measure reports one of the 7 domains, depression. The raw score on the depression subscale is converted to a standardized T-score. T-score is reported here, and it ranges from 0 to 100, with a higher PROMIS T-score representing more of the concept being measured, that is, greater depression. PROMIS uses a T-score metric in which 50 is the mean of a relevant reference population and 10 is the standard deviation (SD) of that population; therefore, a depression T-score of 40 is one SD better than average in terms of depression. A T-score below 55 is indicative of depression within normal limits.
Quality of Life as Assessed by the Patient-Reported Outcomes Measurement Information System (PROMIS-29) - Sleep Disturbance	1 month post completion of the treatment (2 months after baseline)	The Patient-Reported Outcomes Measurement Information System (PROMIS-29) is a 29-item profile instrument that can be used to assess seven subscales of health quality of life (QOL) for each of 7 domains-this outcome measure reports one of the 7 domains, sleep disturbance. The raw score on the sleep disturbance subscale is converted to a standardized T-score. T-score is reported here, and it ranges from 0 to 100, with a higher PROMIS T-score representing more of the concept being measured, that is, greater sleep disturbance. PROMIS uses a T-score metric in which 50 is the mean of a relevant reference population and 10 is the standard deviation (SD) of that population; therefore, a sleep disturbance T-score of 40 is one SD better than average in terms of sleep disturbance. A T-score below 55 is indicative of sleep disturbance within normal limits.
Quality of Life as Assessed by the Patient-Reported Outcomes Measurement Information System (PROMIS-29) - Anxiety	1 month post completion of the treatment (2 months after baseline)	The Patient-Reported Outcomes Measurement Information System (PROMIS-29) is a 29-item profile instrument that can be used to assess seven subscales of health quality of life (QOL) for each of 7 domains-this outcome measure reports one of the 7 domains, anxiety. The raw score on the anxiety subscale is converted to a standardized T-score. T-score is reported here, and it ranges from 0 to 100, with a higher PROMIS T-score representing more of the concept being measured, that is, greater anxiety. PROMIS uses a T-score metric in which 50 is the mean of a relevant reference population and 10 is the standard deviation (SD) of that population; therefore, an anxiety T-score of 40 is one SD better than average in terms of anxiety. A T-score below 55 is indicative of anxiety within normal limits.
Fear-Avoidance as Assessed by the Fear-avoidance Beliefs Questionnaire (FABQ)	1 month post completion of the treatment (2 months after baseline)	The fear-avoidance beliefs questionnaire (FABQ) focuses on participant's beliefs about how physical activity and work affect their pain. The questionnaire consists of 16 items in which a participant rates their agreement with each statement on a 7-point Likert scale where 0 = completely disagree and 6 =completely agree. The total score ranges from 0 to 96. A higher score indicates more strongly held fear-avoidance beliefs.
Pain Catastrophizing as Assessed by the Pain Catastrophizing Scale (PCS)	1 month post completion of the treatment (2 months after baseline)	The PCS was included to detect exaggerated and negative interpretations of pain. It is a self-report scale that consists of13 items. Participants were asked to reflect on past painful experiences and to indicate to which degree he/she experienced symptoms such as helplessness or rumination when feeling pain. This is a 0-4 Likert scale (score sum 0-52) with responses ranging from "not at all" to "all the time," with higher scores indicate stronger catastrophizing.
Relaxation as Assessed by Relaxation Response	1 month post completion of the treatment (2 months after baseline)
Memory as Assessed by the Stroop Test	1 month post completion of the treatment (2 months after baseline)	T-score will be reported, with a range of 0-100, with a higher score indicating better memory.
