MORE in the Management of Lumbosacral Radiculopathy Symptoms: A Randomized Controlled Trial

National University of Natural Medicine60 enrolled

Overview

INTRODUCTION: Chronic low back pain (CLBP) is a ubiquitous musculoskeletal (MSK) complaint that often presents as a chronic and difficult to treat condition. Lumbosacral radiculopathy/radiculitis (LR) or "sciatica" is a common secondary condition that can last well beyond the expected time frame after treatment with physical therapy, oral anti-inflammatory medications, local steroidal injections, and surgery. Challenges in the treatment of LR indicate that persistent pain may have evolved from mechanical to neuropathic. Previous research has shown that, in addition to the aforementioned treatments, mindfulness-based stress reduction (MBSR) is effective in limiting self-reported pain in patients with CLBP and neurogenic conditions such as fibromyalgia. This study proposes a randomized clinical trial to evaluate the effects of a newer mindfulness program, Mindfulness Oriented Recovery Enhancement (MORE), on self-reported pain, physical function, quality of life (QoL), depression symptoms, trait mindfulness, reinterpretation of pain, and surface electromyography (sEMG) findings in patients with LR. METHODS: Participants will be recruited from the Portland, OR metro area. Upon screening and recruitment, participants will receive a battery of questionnaires collecting demographic, self-reported pain, physical function, QoL, depression symptoms, mindfulness, and reinterpretation of pain data. Participants will also undergo sEMG to identify neurological abnormalities that can be characterized diagnostically. Upon enrollment, participants will be randomized to either the mindfulness-based intervention group (MBI), MORE; or the control group, treatment as usual (TAU), for 8 weeks. Self-reported pain measures and sEMG studies will be conducted again at eight weeks post randomization. HYPOTHESES: Primarily, investigators hypothesize that MORE will be effective in improving self-reported pain, physical function, QoL, depression symptoms, mindfulness, and reinterpretation of pain scores after eight weeks of mindfulness training. Secondarily, investigators hypothesize that those individuals with abnormal sEMG findings at baseline will have improved sEMG findings at their eight-week follow-up visit. ANALYSIS PLAN: Changes in self-reported pain, physical function, QoL, depression symptoms, trait mindfulness, and reinterpretation of pain will be analyzed using descriptive statistics as well as ANCOVA. Regression will also be used to evaluate the dose-response relationship between all outcome measures and time spent in mindfulness practice for the intervention group. Finally, ANCOVA will be used to evaluate the relationship between pain and physical function and sEMG findings.

Study Type

Interventions

Mindfulness Oriented Recovery EnhancementOTHER

Participants randomized to the intervention group will undergo an eight-week mindfulness training program as instructed by MORE for the Treatment of Chronic Pain manual. This eight-week intervention will consist of weekly synchronous video conferencing sessions during which participants will be asked to follow along with a guided meditation read by the study lead and to engage in reflection and discussion exercises with other study participants. Participants will also be asked to complete weekly activities and daily mindfulness practices outside of weekly synchronous meetings.

Outcomes

Primary Outcomes

Change in Modified Oswestry Low Back Pain Disability Questionnaire Score

The ODI is designed to assess the intensity of pain and the degree to which pain interferes with activities of daily living such as personal care, lifting, walking, sitting, etc.
