Veterans' Intervention Blending NeuRomodulation and YogA for Chronic Low BackPaiN Treatment: VIBRANT

Veterans' Intervention Blending NeuRomodulation and YogA for Chronic Low Back PaiN Treatment: VIBRANT

The objectives of this VA Merit application are to demonstrate efficacy of combined intermittent theta burst (iTBS) and yoga (iTBS+yoga) intervention on improving pain, function, analgesic use, self-efficacy, quality of life and well-being among Veterans with chronic low back pain (CLBP). This Merit project will directly benefit Veterans and VA Services by demonstrating efficacy of a new, non-medication treatment for Veterans with CLBP in need of non-opioid treatment options. Neuromodulation including iTBS is now offered at over 50 VA hospitals and yoga is among the complementary and integrative health programs being rolled out as a part of VAs Whole Health implementation efforts. Thus, should iTBS+yoga ultimately prove to be efficacious, VA facilities will be well-poised to offer this treatment. A novel, activity-based, non-medication treatment for Veterans with CLBP is of great need given the high prevalence of CLBP.

Significance to VA: Chronic low back pain (CLBP) is the leading cause of disability worldwide and the most common location of chronic pain among Veterans. Medications are the treatment mainstay for CLBP and yet >50% of chronic pain patients receiving medications are treatment resistant. Lack of pain relief from medications can lead to non-prescription opioid use, opioid use disorder, and Veteran death from opioid overdose, which occurs at a higher rate than US Civilians. This Merit will directly benefit Veterans and VA Services by developing a new, neuromodulatory, non-opioid neurorehabilitation treatment for Veterans with CLBP who do not find existing options to be effective or preferable. Innovation and Impact: Yoga is an activity, and mindfulness-based behavioral intervention and is safe and recommended for CLBP. Given the room for improvement of available treatments and considering the life-threatening opioid epidemic, building an evidence base for novel, precise, non-medication approaches for pain management has high impact for VA Healthcare. The non-invasive treatment transcranial magnetic stimulation (TMS) applied to the motor cortex (M1) reduces pain and has remote effects including neuromodulation of pain pathways. Intermittent theta burst stimulation (iTBS), a type of patterned, excitatory TMS, increases M1 excitability. iTBS can prime the brain to boost the impact of interventions provided during this window of enhanced excitability. By activating the M1 through iTBS prior to participation in an evidence-based yoga program, the investigators theorize that iTBS will boost the effects of yoga resulting in improvements in pain, function and quality of life and these improvements will be sustained. The purpose of this Merit project is to demonstrate efficacy and additive effect of combined iTBS and yoga (iTBS+yoga) and vs. yoga or iTBS alone on improving pain, function, analgesic use, self-efficacy, quality of life (QOL) and well-being among Veterans with CLBP. This Merit is a natural progression of a VA RR&D-funded SPiRE suggesting that iTBS+yoga is safe, feasible, and acceptable among Veterans of all genders with CLBP and provides preliminary evidence of improvements from pre- to post-treatment in pain and QOL. The investigators will build on this evidence and add innovation by testing the additive effects of iTBS+yoga vs. yoga and iTBS each alone. For this Merit, the investigators will complete a randomized controlled trial among 3 groups of Veterans with CLBP receiving (1) active-iTBS+yoga, (2) sham-iTBS+yoga, or (3) active-iTBS alone. Specific Aims: Aim 1 will determine efficacy and sustainability of iTBS+yoga on pain, function, analgesic use, self-efficacy, QOL and well-being among Veterans with CLBP. Aim 2 will determine acceptability of iTBS+yoga for Veterans with CLBP. Exploratory Aim 3 will examine gender and common comorbidity measures as moderators of iTBS+yoga treatment effect. Methodology: The intervention will be provided in small group settings once a week for 6 weeks. Ac-tive- or sham-iTBS will be administered immediately prior to yoga. The investigators will be using an existing, evidence-based, manualized yoga program (LoveYourBrain Yoga). The investigators will collect outcome data related to pain, function, analgesic use, self-efficacy, QOL and well-being, as well as structural MRI data for iTBS neuronavigation. Path to Translation/Implementation: Completion of this Merit project will provide preliminary data for future applications focused on treatment responsiveness and a future larger scale multi-site pragmatic effectiveness study. This Merit project will directly benefit Veterans and VA Services by developing a new, non-pharmacological neurorehabilitation treatment for Veterans with CLBP in need of non-opioid treatment options. TMS is now offered at over 50 VA hospitals nationwide for treatment-resistant depression, and yoga is among the complementary and integrative health programs being rolled out as a part of VAs nation-wide Whole Health implementation efforts. Therefore, should iTBS+yoga ultimately prove to be efficacious and effective, VA facilities will be well-poised to offer this treatment.
