Battlefield Acupuncture for Low Back Pain (BFA)

The purpose of this study is to determine the effect of Battlefield Acupuncture (BFA) on outcomes for pain, sleep, and physical activity level in an active duty military sample with subacute or chronic lower back pain (LBP). BFA is a form of auricular acupuncture (AA) that has been implemented in many Department of Defense (DoD)/Veterans Affairs (VA) medical settings to alleviate acute or chronic pain. BFA uses five predetermined locations in a defined sequence to place semi-permanent needles in the ear. Subacute lower back pain is pain that has persistently lasted from four to twelve weeks. Chronic lower back pain is pain that lasts more than 12 weeks.

Hypothesis 1: Participants with subacute or chronic LBP will have reduced pain using BFA as compared to placebo.

Hypothesis 2: Participants with subacute or chronic LBP will have improved physical activity using BFA as compared to placebo.

Hypothesis 3: Participants with subacute or chronic LBP will have improved sleep quality as compared to placebo.

The secondary study aims are:

1. To explore the effects of BFA two weeks following the treatment for LBP.

   1. Do positive outcomes appreciated with BFA persist over two weeks?
   2. What is the pain medication usage during and after intervention treatments?

2. To explore the effectiveness of BFA on trunk flexion mobility and balance.

   1. Does pain reduction improve trunk flexion and balance?
   2. Does improved truck flexion mobility and balance contribute to increased physical activity?

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Sham Comparator: Sham Treatment; Participants will continue to receive usual care from their primary care provider, which can include medications, physical therapy, biofeedback, and education according to DoD/VA guidelines for LBP management. Participants randomized to this arm will also receive a sham intervention, pointing a laser pointer to the ear without turning the laser on.	Other: Sham Treatment; Laser pointer pointed at the ear, but not turned on.
Experimental: Auricular Acupuncture; Participants will continue to receive usual care from their primary care provider, which can include medications, physical therapy, biofeedback, and education according to DoD/VA guidelines for LBP management. Participants randomized to this arm will receive up to five ASP needles per ear placed in the predetermined BFA pattern. Needles are placed until the participant states pain is reduced 1/10.	Other: Auricular Acupuncture; Up to five small ASP needles placed in each ear until pain is reduced to 1/10.; Other Names: Battlefield Acupuncture (BFA)

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain level change over time on the Defense/Veterans Pain Rating Scale(DVPRS).	Participant reported pain level using the DVPRS. DVPRS pain level ranks from 0 (no pain) to 10 (As bad as it can be. Nothing else matters).	The DVPRS will be administered weekly for seven times. Followed by a one time washout 2 weeks later.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in pain medication need.	A self reported increase, decrease, or no change in medication use.	A medication form will be administered weekly for seven times. Followed by a one time washout 2 weeks later.
Change in trunk flexion.	Trunk flexion will be assessed with Dual Digital Inclinometers. The Dual Digital Inclinometer is placed around the sacrum and measures the angle of flexion.	Trunk flexion will be administered weekly for seven times. Followed by a one time washout 2 weeks later. If the participant has a DVPRS >=2 and mODI >=20%, trunk flexion will also be measured after the intervention.
Change in balance	Balance is measured by Functional Reach Test(FRT) and Timed Up and Go Test(TUG). The FRT assesses a patient's stability by measuring the maximum distance an individual can reach forward while standing in a fixed position. The TUG is a simple test used to assess a person's mobility and requires both static and dynamic balance. It measures the time that a person takes to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down.	The FRT and TUG will be administered weekly for seven times. Followed by a one time washout 2 weeks later. If the participant has a DVPRS >=2 and mODI >=20%, the FRT and TUG will also be measured after the intervention.
Change in physical activity	Activity will be measured using an Actigraph watch and Modified Oswestry Low Back Pain Disability Questionnairre(mODI)	The mODI will be administered weekly for seven times. Followed by a one time washout 2 weeks later. The Actigraph watch is worn the entire 8 weeks.
Change in sleep quality	Sleep will be measured using an Actigraph watch, Epworth Sleepiness Scale(ESS), and Insomnia Severity Index(ISI)	The ESS and ISI will be administered weekly for seven times. Followed by a one time washout 2 weeks later. The Actigraph watch is worn the entire 8 weeks.

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Health and well being	Health and well being is measured using the SF-8 Health Survey (4 Week Recall).	The SF-8 is administered the first, fourth, and eighth week.
Height, weight, and Body Mass Index(BMI)	The participants height and weight is measured. A BMI is also calculated using the following formula: BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in meters squared.	Height, weight, and BMI is measured the first and eighth week.
