Comparative Clinical Trial: Manual Therapy with and Without Radial Extracorporeal Shockwave Therapy to Treat Acute Low Back Pain
Description

The goal of this clinical trial is to learn if the addition of radial pulse therapy to chiropractic care will help adult patients recover faster to an acute bout of low back pain. Radial pulse therapy is the application of acoustic waves that passes through the skin to tissues and cells in the body. The main questions that the clinical trial aims to answer are: * Does the addition of radial pulse therapy to chiropractic care result in better or earlier reduction in pain intensity? * Does the addition of radial pulse therapy to chiropractic care result in better or earlier improvement in physical function? Researchers will compare radial pulse therapy plus chiropractic care to chiropractic care alone to see if patients with acute low back pain recover faster with the addition of radial pulse therapy. Participants will: * Visit the clinic once a week for 5 weeks * Receive chiropractic care with or without the addition of radial pulse therapy to the low back and hip regions of the body * Report their pain intensity and perform a physical function test at each clinic visit

Effects of a Lower Back Wrap Device on Lower Back Pain, Physical Function, and Quality of Life
Description

The goal of this counterbalanced cross-over study is to determine whether a recovery lumbar wrap effectively reduces lower back pain and improves outcomes related to physical function and quality of life in adults with LBP in adults 20-65 years old. This study will also explore whether improvements in other health metrics that are typically related to, or seen in, lower back pain research (i.e. stiffness, mobility, physical activity, validated clinical scoring methods, etc.) are improved with the use of the product. The main question this study aims to answer is: • Does the lumbar wrap effectively reduce low back pain symptoms and improve outcomes related to physical function and quality of life in adults with lower back pain. Participants experiencing lower back pain will be asked to use the lower back wrap for at least 20-minutes per day for a 2-week period, counterbalanced with a 2-week period of no device use. Participants will fill out small daily surveys about their symptoms and complete a pre-, middle-, and post- survey and functional screening to determine efficacy of the device.

Assessing the Functional Movement Screen as a Reliable Physical Therapy Discharge Criteria for Chronic Lower Back Pain Patients
Description

Overview of Research Design and Objectives This study is a prospective, concurrent cohort study aimed at evaluating the reliability of the Functional Movement Screen (FMS) as a discharge criterion for patients with chronic lower back pain (LBP) undergoing physical therapy. The primary objective is to identify a benchmark FMS score that correlates with a low risk of recurrence and high levels of functional performance post-discharge. Specific Aims and Hypotheses The study specifically aims to: Assess the effectiveness of FMS in determining discharge readiness for chronic LBP patients. The hypothesis is that a specific threshold score on the FMS can reliably indicate a patient\'s readiness for discharge, reducing the risk of recurrence and ensuring better long-term functional outcomes. Rationale for the Study Chronic LBP is a prevalent condition requiring multidisciplinary management. The FMS, widely used in athletic and military settings, has potential utility in clinical management of chronic LBP, particularly in establishing discharge criteria. This study seeks to explore this potential, addressing a gap in evidence regarding discharge benchmarks for chronic LBP patients. Procedures The study involves 50 chronic LBP patients from the Texas Back Institute. Participants will undergo their standard physical therapy regimen, supplemented by regular FMS assessments to evaluate discharge readiness. Assessments include a series of functional tasks, with scores ranging from 0 to 3 for each task, culminating in a total possible score of 21. Risks and Anticipated Benefits Risks are minimal, akin to those in low-intensity exercises. Benefits include improved discharge criteria for chronic LBP patients, potentially enhancing long-term outcomes. All procedures adhere to Good Clinical Practice and Health Insurance Portability and Accountability Act guidelines. This study\'s risks include potential loss of confidentiality, psychological, and physical risks. Physical risks are minimal, similar to those in low-intensity exercises like squatting and lunging. To protect confidentiality, data will be managed in compliance with Good Clinical Practice and HIPAA guidelines, with encryption and secure storage. Psychological and physical risks are mitigated through thorough instruction, practice trials, and breaks for participants. Additionally, trained study personnel can terminate a participant\'s involvement at any point for safety reasons. Outcomes The study will report on the average FMS score correlating with discharge readiness and the variance in scores across different functional assessments. Statistical Analysis Data will be analyzed using descriptive statistics, correlation analysis, and repeated measures ANOVA or Friedman Test, with a significance level set at α=0.05. Completion Time The study is expected to complete enrollment within two years.

Photobiomodulation for Lower Back Pain Post Spinal Fusion and Decompression Surgery
Description

After spinal fusion and decompression surgery there is a possible risk of developing chronic back pain. After surgery there is typically inflammation around the operation site and this inflammation can be painful and debilitating to patients. Many possible treatment plans have been incorporated to assist the patient with recovery - notably medications, physical therapy, and braces. However, few studies have looked at laser diodes that utilize high-power laser lights that are aimed at decreasing pain and inflammation. Investigators aim to look compare patients using a back brace with laser diodes within versus those who wear a normal brace used as a placebo. Investigators will also assess the patient's surgical wound to monitor the progression of wound healing while using the brace.

Implementing Group Battlefield Acupuncture in CCRCs for the Treatment of Chronic Lower Back Pain
Description

Lower back pain (LBP) is one of the most common causes of disability, with 68% of adults over 60 years of age suffering from chronic Lower Back Pain (cLBP). In addition to the exacerbation of physical, social and emotional health issues, LBP has a staggeringly high US economic burden. Community-dwelling older adults experience a significant amount of chronic pain and treatments that are effective in their younger adult counterparts (e.g., pain medications, exercise) are often not safe or feasible. Our long-term goal is to decrease cLBP and improve function in older adults residing in continuing care retirement communities (CCRC). Battlefield Acupuncture (BFA), a promising treatment for cLBP, is an auricular (ear-based) treatment intended to compliment traditional allopathic medical treatments for acute and chronic pain. Auricular acupuncture has been implemented and used widely in the US military. Despite emerging evidence supporting the use of BFA in chronic pain, BFA has not been used to treat older adults with cLBP residing in CCRC. To this end, we propose an adapted group BFA protocol for CCRC residents. We will determine the feasibility and acceptability of implementing group BFA for cLBP at the University of Iowa (UI) Family Medicine-affiliated CCRCs by evaluating patient participation rates and retention, comfort with the protocol and satisfaction with the sessions, protocol delivery and ease of use. We will also determine treatment effectiveness by evaluating pain scales in cLBP, pain medication use, mobility, and falls. Data obtained from this study will inform the design of a future clinical trial testing group BFA for the management of cLBP in older adults.

A Mediation Analysis Investigating Dry Needling Treatment Mechanisms in a Chronic Low Back Pain Population
Description

Low back pain is a common problem that many adults experience at some point in their lives. One treatment being studied is dry needling, a technique where a small needle is inserted into a specific area of muscle to help relieve pain. So far, the research on dry needling for low back pain hasn't been clear, and it's hard to know when and for whom it will work best. This study aims to figure out how dry needling works to help people with chronic low back pain by looking at the underlying factors. By understanding how dry needling helps people, we can develop a more targeted approach to treatment, which could lead to better outcomes for people with chronic low back pain. The goal of this study is to identify the factors that make dry needling effective for people with chronic low back pain, so that this this information can be used to provide more personalized and effective care. Eligible participants will attend 5 research sessions lasting approximately 1 hour and complete 2 online surveys. At 3 of those sessions, participants will receive dry needling to their low back. As part of the research, participants will complete questionnaires related to how pain effects their life. Participants will also undergo testing for muscle stiffness, low back mobility and strength, and pain sensitivity. To be included in this study participants must: * Be 18-65 years of age * Have low back pain for at least 3 months

Telerehabilitation for Patients With Chronic Low Back Pain (TeleBACK Clinical Trial)
Description

The investigators will conduct a prospective, randomized, clinical trial addressing key questions to understanding the effectiveness of telerehabilitation (physical therapy delivered via video-visits) and in-clinic physical therapy for patients with chronic low back pain (LBP). The investigators also seek to understand how patients engage with both care options and how these treatment options influence other LBP-related healthcare utilization. The investigators will explore implementation outcomes using a mixed methods approach consisting of electronic surveys and semi-structured interviews with patients, physical therapists, practice managers, and outpatient services administration focusing on perceived quality and impact on barriers to care. The investigators will enroll 1000 patients with chronic LBP seeking outpatient care at the healthcare systems in Maryland (Johns Hopkins Medicine (JHM)) and Utah (University of Utah (UU) and Intermountain Healthcare (IHC)). Eligible patients will provide informed consent and be randomized to receive telerehabilitation or in-clinic physical therapy delivered by a trained physical therapist. Primary effectiveness outcome is the difference in change in LBP-related disability (Oswestry Disability Index) after 8 weeks of treatment.

Physical Exam, Static & Dynamic Ultrasound Assessment, & Treatment of Thoracolumbar Fascia (TLF) Mediated Low Back Pain
Description

This Study is for our continued study of the Thoracolumbar Fascia (TFL) in patients with and without low back pain by our experienced multidisciplinary team: Vincent Wang PhD, VT Biomedical Engineering \& Mechanics (BEAM). Albert J Kozar DO, FAOASM, R-MSK. P. Gunnar Brolinson, DO, FAOASM, FAOCFP. David T. Redden PhD, VCOM Research Biostatistician. Matthew Chung DO, VCOM and Team Physician at Virginia Tech. Edward Magalhaes, PhD, LPC, Psychiatry and Neuro- Behavioral Sciences, VCOM. This listing is specifically for our renewed efforts via two, Department of Defense (DoD) and American Osteopathic Association (AOA), extramurally, simultaneously funded grants for similar but distinct projects. Both funding sources are aware of each other's funding and have approved their grant study moving forward simultaneously with some integration. DoD: Machine Learning Analysis of Ultrasound Images for the Investigation of Thoracolumbar Myofascial Pain and Therapeutic Efficacy of Hydrodissection. The primary objectives of the proposed project are to: 1. develop reliable, quantitative image analysis approaches to objectively distinguish images from subjects with acute or chronic TLF pain from those without pain and 2. to assess the preliminary clinical efficacy of hydrodissection of the TLF as a novel therapeutic treatment for chronic LBP. AOA: Assessment of the Therapeutic Efficacy of OMT on Chronic Low Back Pain: An Integrated Sonographic and Machine Learning Analysis of Thoracolumbar Fascia Glide Impairment. The primary objectives of the proposed project are to: 1. assess the preliminary clinical efficacy of OMT as a therapeutic treatment for CLBP of TLF origin and 2. develop reliable, quantitative image analysis approaches to objectively distinguish images from subjects with TLF pain from those without pain. These projects will share 50 no LBP subjects as controls. The DOD study will include 50 acute LBP and 50 CLBP. The AOA study will include 50 CLBP. This project uses standard surveys, physical exam, functional tests, and ultrasound imaging to obtain both static images of the TLF at multiple transition zones. It further uses ultrasound to evaluate the dynamic gliding motion, via cine loops, of this fascia in 2 different body movements in subjects with acute low back pain (ALBP), with chronic low back pain (CLBP), and without low back pain (WLBP). All images will be clinically analyzed and further assessed by textural and machine learning analysis. Patients with CLBP (only) will choose to enter one of the two studies (DoD vs AOA) at the time of consent. All images will be clinically analyzed and further assessed by textural and machine learning analysis. Patients with CLBP (only) that are found to have TLF glide impairment or positive physical exam maneuvers suggesting TLF as etiology will enter the treatment arm of the chosen study at the time of consent, either ultrasound guided hydrodissection (USGH), or Osteopathic Manipulative Therapy (OMT). After receiving 3 treatments utilizing one of these modalities, the CLBP participants will have repeat standard surveys, physical exam, functional tests, and ultrasound imaging assessments at 2,4,6,12, and 24 weeks post-treatment. At the conclusion of this project, the investigators expect to have developed, refined, and implemented robust and feasible experimental and computational approaches which can be further expanded in larger-scale studies. The development of our data-driven computer models for the objective analysis of sonographic images of the TLF has high potential impact as it seeks to transform the assessment of TLF integrity, injury and healing via establishment of reliable US imaging biomarkers. The investigators anticipate that the tools developed will have broad utility to assess a variety of clinical treatments for the TLF. The investigators also hope to validate physical exam maneuvers that may predict TLF mediated LBP and have preliminary evidence of the efficacy of hydrodissection and OMT in TLF mediated LBP. In pursuit of these objectives, the investigators will adopt an innovative approach featuring a robust integration of clinical imaging, physical exam, pain and functional outcomes, quantitative image analysis, and machine learning analyses. Specific Aim 1: Compare sonographic TLF imaging characteristics in individuals with acute versus chronic pain to those without low back pain. Specific Aim 2: Develop a machine learning (ML) classification algorithm to reliably distinguish abnormal myofascial tissue in acute versus chronic pain stages from healthy tissue. Specific Aim 3: DoD Study: Assess the preliminary therapeutic efficacy of hydrodissection as a novel treatment for TLF pain using quantitative US imaging and ML tools. AOA Study: Assess the preliminary therapeutic efficacy of OMT as a treatment for CLBP using quantitative US imaging and ML tools.

Is Conditioned Pain Modulation Predictive of Clinical Improvement in Patients With Chronic Low Back Pain?
Description

Conditioned pain modulation (CPM) a measure of the effectiveness of the descending pain pathway and therefore a measure of the body's ability to perform endogenous analgesia. In subjects with normal function of the descending pain pathway, the net-effect during CPM testing is anti-nociceptive, or inhibition of the ascending pain pathway. In those with impaired descending pain pathway function, the response to CPM testing is pro-nociceptive, indicating that the body is unable to inhibit the pain signal, or may even amplify it. There is literature that supports the presence of impaired CPM, and therefore impaired descending pain pathway function, in numerus chronic pain conditions, including low back pain. Impaired descending pain pathway function may be contributing to this chronic pain presentation. This study will give us information on whether a typical physical therapy plan of care is able to improve impaired CPM, and if CPM values are predictive of improvement in physical therapy.

Phenotyping Response to Spinal Cord Stimulation in Chronic Low Back Pain
Description

Chronic low back pain (CLBP) is a debilitating condition and costly to treat. Long-term drug treatment often fails due to habituation, breakthrough of pain, or adverse effects of drug treatment. Opioid use to manage this pain has contributed to the opioid epidemic. Spinal cord stimulators have emerged as a promising treatment and reduces reliance on drugs. However, response to spinal cord stimulation (SCS) is unpredictable. It is difficult to predict which patients will respond positively to SCS because the physiological mechanism for treatment responsiveness is unclear. Therefore, the aim of this study is to investigate how spinal cord stimulators affect functional measures in patients with CLBP, including functional MRI, neurophysiology, gait analysis, and questionnaires. The results of this study can lead to the widespread adoption of spinal cord stimulators as a safe and effective therapy for CLBP, reducing the reliance on opioids and mitigating the opioid epidemic's impact.

Self-management of Low Back Pain in Horticulture Workers
Description

The primary purpose of this hybrid Type II comparative effectiveness and implementation study is to compare two self-management strategies in nursery and landscape workers. This randomized pragmatic study will compare interventions with different degrees of support to determine if self-management videos plus multimodal personalized support is more effective than self-management videos alone for improving LBP among horticulture workers. Both groups will review short self-management video modules to introduce general pain concepts and the importance of managing pain without medication, risks of opioid use, self-management of pain, and simple ergonomic strategies for both groups. Both groups will choose 1 self-management strategy to manage pain at home and 1 ergonomic workplace strategy to limit pain. The video+support group will receive 1) check-list guidance, 2) review videos of their work tasks, and 3) receive text reminders to support implementation. Surveys will include instruments reflecting low back pain disability, pain, work ability, and affective or cognitive characteristics (self-efficacy, pain anxiety, depression, coping), collected at baseline, pre- and post-intervention, with follow-ups at 3- and 6-months. Workers will be videoed pre- and post-intervention for calculation of work risk and to compare any changes after the intervention. Specific aim 2 will identify contextual factors impacting engagement, adoption, effectiveness, and implementation. Interviews, focus groups, and field notes will be used to explain results and establish patterns to inform future translation.

Detection of EEG-Based Biomarkers of Chronic Low Back Pain
Description

Chronic low back pain (CLBP) is a pervasive disorder affecting up to one-fifth of adults globally and is the single greatest cause of disability worldwide. Despite the high prevalence and detrimental impact of CLBP, its treatments and mechanisms remain largely unclear. Biomarkers that predict symptom progression in CLBP support precision-based treatments and ultimately aid in reducing suffering. Longitudinal brain-based resting-state neuroimaging of patients with CLBP has revealed neural networks that predict pain chronification and its symptom progression. Although early findings suggest that measurements of brain networks can lead to the development of prognostic biomarkers, the predictive ability of these models is strongest for short-term follow-up. Measurements of different neural systems may provide additional benefits with better predictive power. Emotional and cognitive dysfunction is common in CLBP, occurring at the behavioral and cerebral level, presenting a unique opportunity to detect prognostic brain-based biomarkers. Likewise, improvements in electroencephalogram (EEG) neuroimaging strategies have led to increased spatial resolution, enabling researchers to overcome the limitations of classically used neuroimaging modalities (e.g., magnetic resonance imaging \[MRI\] and functional MRI), such as high cost and limited accessibility. Using longitudinal EEG, this patient-oriented research project will provide a comprehensive neural picture of emotional, cognitive, and resting-state networks in patients with CLBP, which will aid in predicting symptom progression in CLBP. Through this award, the investigators will use modern EEG source analysis strategies to track biomarkers at baseline and 1- and 2-month follow-ups and their covariance with markers for pain and emotional and cognitive dysfunction. A 5-month follow up will also be used to only assess patient reported outcomes. In Aim 1, the investigators will identify and characterize differences in resting-state, emotional, and cognitive networks between patients with CLPB and age/sex-matched controls. In Aim 2, the investigators will identify within-subject changes across time and their relationship with clinical symptoms. In Aim 3, as an exploratory aim, the investigators will apply machine- and deep-learning strategies to detect a comprehensive signature of CLBP using EEG features from resting-state, emotional, and cognitive networks.
